Cisco CIUS Secure Enterprise Android Tablet Product Review

Cisco's new enterprise Android tablet, the Cisco CIUS, is different from all the other Android tablets available. It is not intended for the consumer market, but for the very different enterprise business market. You won't see this in stores, and unless an organization has a number of things working on the back end, it has nothing different than any other Android tablet.

This is a difficult product to classify, because the tablet aspect is only one part of its capabilities. It is also a phone, desktop video conferencing device, and virtual desktop endpoint. Furthermore, it is designed from the ground up to be secure. With all these capabilities, it can be a very useful device for organizations that are ready to take advantage of all it can offer.

There are two versions of the Cisco CIUS, pronounced "see-us". The one that shipped first is the 7" version, and is the one that I have been using and demonstrating to people. The 7" tablet is running a Cisco Android version based on version 2.2 Froyo. There is rumor of a 10" version available soon, but no confirmation.

The most engaging part of the demonstrations that we have been doing for customers is the High Definition video conferencing client using either the front or back cameras. The HD video operates at 720p with 30 fps, and is a high quality video conference. It is a very different video calling experience than one gets from Google Talk or Skype, which are lower resolution with a lower frame rate.

CIUS Specifications:

Size: 5.5 x 8.9 x 0.6 inches
Weight: 1.2 lb
Screen resolution: 1024 x 600 pixels
Processor: Intel Atom Z615 at 1.6GHz
Memory: 1 GB RAM and 32 GB Flash
Connections: micro USB, micro SD, micro HDMI
Wireless connectivity: 802.11 a/b/g/n with 3G and 4G in future, bluetooth 2.1
Operating System: Android Froyo 2.2.2
Camera: front and rear facing 1280 x 720, 5 megapixel

Docking station specifications:

3 USB ports
Gigabit ethernet wired
DisplayPort with cables for VGA, DVI, HDMI
Can be powered by 802.3at, PoE class 4

Pros

Enterprise tablet that is manageable with a controlled App store.
Cisco IP Telephony endpoint with video and voice calls.
Standards based HD video endpoint with 720p resolution at 30 fps and dual cameras.
Secure operation with Cisco AnyConnect VPN.
Replaceable battery.

Cons

Heavier than similar sized Android tablets.
Requires other Cisco applications to take full advantage of capabilities.
7" form factor too small for full virtual desktop client unless using XenApp.
7" version has low external monitor resolution at 1024x600.
Cisco Unified Communications Manager version 8.5.1 or later required.

There are a few different back end applications that are necessary to put into place to give the Cisco CIUS basic functionality. The CIUS can operate as a full Android tablet with access to the Google Apps Market only, but I expect that most organizations are not going to want to limit it to being just a tablet.

The first application to set up for Enterprise deployment of the Cisco CIUS is the Cisco Unified Communications Manager version 8.5.1 or later. This application provisions and updates the Cisco CIUS. It allows the organization to create an internal App store, with applications that can be pulled from the Cisco App store and the Android market. This addresses multiple concerns, although it is required to set up an account at Cisco which has an additional fee. The first is that only Apps that are approved can be loaded on the organization's CIUS's. The second is site or block user licensing for purchased applications. Additionally, it centrally controls tablet security.

The CIUS docking station enhances the capability of the tablet significantly. I have found that keeping the dock plugged into an external monitor, keyboard, and mouse enhances the usability of many applications, and is almost a necessity given the small size of the 7" form factor. Even the video output ports on both the dock and tablet support both VGA and HDMI, one drawback is the low external resolution size, which is limited to 1024x640 pixels.

The CIUS docking station turns the Cisco CIUS into a full Cisco IP phone. The best way to use a Cisco IP phone is to connect it into a Cisco Communications Manager server. The Cisco Communications manager can be the company's entire phone system, and it is currently the #1 shipping business phone system in the world, so there are many organizations that could take advantage of this capability. If an organization has a different phone system, it is still possible to stand up a small Cisco Communications manager installation for just the Cisco CIUS's, and then integrate the Cisco phone system into the company's existing IP or traditional phone system.

The HD video conferencing endpoint capabilities of the CIUS can be enabled by connecting it into the Cisco Communications Manager, but for full HD video conferencing capabilities it is best to have the Cisco Video Infrastructure in place. This provides for standards based video calls to other organizations over the internet, HD video conferences using a centralized conferencing codec, and bandwidth management for the calls.

The Cisco CIUS can be used as a full Virtual Desktop endpoint using either VMware View or Citrix HDX Receiver for Citrix XenApp and XenDesktop. The two virtual desktop applications have their pros and cons, and it is good that the Cisco CIUS supports both. At the 7" form factor when not using the external monitor, the most useful is Citrix XenApp, which provides full screen application capability.

It is important to operate the Cisco CIUS over a good network. Both the Local Area Network and the Wide Area Network has to have a good Quality of Service policy implemented, and there has to be sufficient bandwidth for the voice, video, and virtual desktop streams. The CIUS preferentially uses 802.11n wireless LAN for call control even when docked, so it is best to have a good wireless infrastructure in place that has sufficient coverage, bandwidth, and Quality of Service. The advantage of always using wireless for call control is to allow the user to undock the CIUS in the middle of a video or voice call and to permit it to continue the call without interruption.

The Cisco CIUS is a new category of tablet device that is focused at a distinctly different market than the consumer tablets from Apple and other Android tablet manufacturers. When it is deployed in an enterprise environment that has the right types of back end applications, it can be a very useful device. The two issues of small screen size and low external monitor screen resolution on the 7" CIUS are a limitation for its use as a general purpose tablet. This is overall a good product that works well and can be the main device for a mobile device strategy. It is an especially good choice for organizations that have concerns about security and have existing voice, video, and virtualization deployments.

How to Configure SSH (Secure Shell) For Remote Login on a Cisco Router

Prior to the introduction of SSH in the Cisco IOS, the only remote login protocol was Telnet. Although quite functional, Telnet is a non-secure protocol in which the entire session, including authentication, is in clear text and thus subject to snooping.

SSH is both a protocol and an application that replaces Telnet and provides an encrypted connection for remote administration of a Cisco network device such as a router, switch, or security appliance.

The Cisco IOS includes both an SSH server and an SSH client. This document is concerned only with the configuration of the SSH server component.

Prerequisites

Software

The SSH server component requires that you have an IPSec (DES or 3DES) encryption software image from Cisco IOS Release 12.1(1)T or later installed on your router. Advanced IP services images include the IPSec component. This document was written using c2800nm-advipservicesk9-mz.123-14.T5.bin.

Pre-configuration

You must configure a hostname and a domain name on your router. For example:

router#
router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router01(config)#hostname router01
router01(config)#ip domain-name domain.local

You must also generate an RSA keypair for your router which automatically enables SSH. In the following example, note how the keypair is named for the combination of hostname and domain name that were previously configured. The modulus represents the key length. Cisco recommends a minimum key length of 1024 bits (even though the default key length is 512 bits):

router01(config)#
router01(config)#crypto key generate rsa
The name for the keys will be: router01.domain.local
Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.

How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys ...[OK]

Finally, you must either use an AAA server such as a RADIUS or TACACS+ server or create a local user database to authenticate remote users and enable authentication on the terminal lines. For the purpose of this document, we'll create a local user database on the router. In the following example, the user "donc" was created with a privilege level of 15 (the maximum allowed) and given an encrypted password of "p@ss5678". (The command "secret" followed by "0" tells the router to encrypt the following plaintext password. In the router's running configuration, the password would not be human readable.) We also used line configuration mode to tell the router to use its local user database for authentication (login local) on terminals lines 0-4.

router01(config)#username donc privilege 15 secret 0 p@ss5678
router01(config)#line vty 0 4
router01(config-line)#login local

Enabling SSH

To enable SSH, you must tell the router which keypair to use. Optionally, you can configure the SSH version (it defaults to SSH version 1), authentication timeout values, and several other parameters. In the following example, we told the router to use the previously created keypair and to use SSH version 2:

router01(config)#
router01(config)#ip ssh version 2
router01(config)#ip ssh rsa keypair-name router01.domain.local

You can now log on to your router securely using an SSH client such as TeraTerm.

Viewing SSH Configurations and Connections

You can use the privileged mode commands "view ssh" and "view ip ssh" to view SSH configurations and connections (if any). In the following example, the SSHv1 configuration from a Cisco 871 router is verified using "show ip ssh" and a single SSHv1 connection is displayed using the command "show ssh". Notice that we did not enable SSHv2 on this router, so it defaulted to SSH version 1.99. Also note in the output of the "show ssh" command that SSH version 1 defaults to 3DES. SSHv2 supports AES, a more robust and efficient encryption technology. SSHv2 is also not subject to the same security exploits as SSHv1. Best practice recommends the use of SSHv2 and disabling a dropback to SSHv1. Enabling SSHv2 disables SSHv1. This example is included only to demonstrate backwards compatibility:

router04#
router04#show ip ssh
SSH Enabled - version 1.99
Authentication timeout: 120 secs; Authentication retries: 3
router04#
router04#show ssh
Connection Version Encryption State Username
2 1.5 3DES Session started donc
%No SSHv2 server connections running.
router04#

You can also use the command "debug ip ssh" to troubleshoot SSH configurations.

Security and Software Development: Secure Coding Standards

Algorithmic vulnerabilities are technical flaws in a manmade component, typically hardware and software. In software, the flaws can be design flaws or implementation flaws, commonly coding errors. Software infected with bugs has been a problem for decades, software engineering was invented to find ways to minimize them, and formal methods were invented to eliminate them, but attaining the goal has been quite elusive. In the preceding years, security issues have occasionally raised awareness of problems, notably buffer overflow attacks that were eventually resolved by improved coding techniques. SQL injection attacks are, in some ways, an evolution of buffer overflow and can also be prevented by proper coding.

Coding standards are a classic solution to the problem of preventing coding flaws from infesting new software. In many shops, the standards were used to assure maintainable software was produced. The typical standard consisting of a list of requirements to be applied by programmers when writing code. They were then enforced during code reviews and other activities linked to quality control.

The same approach can be applied to a list of techniques to prevent exploitable algorithmic vulnerabilities. Any number of authoritative sources are readily available, so generating a list of techniques is more a library exercise than a laboratory one. Further, consultancies specializing in advising on solutions can be easily found by simple Internet searches.

There are several advantages to creating and using an in-house standard. Involving programmers in researching, writing and reviewing the standard helps overcome resistance and generate a sense of ownership. Also, language-specific issues can be focused on, ensuring the result is appropriate to the environment.

A coding standard should be regularly reviewed to ensure it remains fit for purpose, as new attacks appear that focus on previously unrecognized vulnerabilities, the Standard needs to be updated to address techniques to prevent the vulnerabilities, minimizing the new risks.

Vulnerability scanners have been in use for at least a quarter century. Scanners specializing on applications are available and are useful in identifying problems.

Secure coding standards provide agreed requirements used in the software development lifecycle, usually in the coding and testing activities. Test Plans should provide procedures for testing based on the standard's requirements.

Application programming in not often thought of as being relevant to security; this is an oversight, as it certainly is very important. Secure coding standards corrects this error by providing requirements for avoiding exploitable algorithmic vulnerabilities from appearing in new code and systems.

The Secure Erasing and Disposal of Electronic Media

When you are looking at a place where you are looking to make sure that your data is secure, you are going to find that one of the first things that you need to think about is how to dispose of your electronic media in a safe and secure way. When you are working in any industry that involves handing money, or the sensitive data of other people, you will find that good disposal of your various media is quite important. Whenever you put anything on your hard drive, remember that it does not go away if you delete it! The information lingers and you will find that someone who knows what they are doing can remove the data in question. To make sure that you are considering all of your options, think about what you need to do to make sure that your data is secure.

The first method that is often used when it comes to the destruction of electronic media and hard drive is physical destruction. The plates and discs that hold the information are susceptible to effective harm, and you will find that when you are looking to make sure that you have disposed of the media that you are working with completely that this is a service that often comes up. Remember that it can take a surprisingly large amount of harm to really destroy data; a lot of the companies offer this option when it comes to shredding everything from CDs to DVDs to hard drives. While it might seem a little excessive, remember how important the data on the media was!

The other method that is commonly used to destroy electronic media is degaussing, where magnets are used to destroy the information. You will find the magnets that should be used in this procedure need to be ranked by the Department of Defence. The use of this method of data erasure does render the media unusable and you will find that it can be dangerous for people with pacemakers to be present while this is happening. It is also important to make sure that an adequate amount of passes are used to remove all of the data in question.

There are also various types of software that you can find to delete information, but keep in mind that at this point in time, degaussing and physical destruction are the only methods that are one 100% proven to remove sensitive data from a disc and make it completely unrecoverable. When you are dealing with sensitive information, you may find that your industry has rules about how you get rid of your electronic media, so make sure that you are aware of them.

At the end of the day, whoever said that knowledge is power was definitely right; make sure that the data you are getting rid of does not come back to haunt you and take the time to make sure that you are in a place where you are thinking about the right methods for you to use.

Become a Secure Wireless Router - 3 Important Things to Know

To learn how to make a wireless router is important to know three things for backup: SSID, MAC address and WEP / WPA. Of course there are a number of abbreviations, which we discuss counted. There are many aspects of setting up a wireless router in a secure manner. These three things are not the only issues involved, but some of the most important.

First SSID

Service Set Identification is basically the name associated with a device on a network - in this case, theWi-Fi router. There is no password, user ID or username. But it has come into play when you connect to wireless networks. On most PCs or other wireless devices, you can view a list of available wireless networks. If you see this list on your device, you will notice that the devices have a name connected with them on the display. This is the SSID.

If you buy a wireless router, take it out of the box and plug it in, the chances that the SSID will show the name of the manufacturer. AHackers or others intent on invading your wireless network, the default settings in this way that they have a clue how to get around the system. Out of the box, most wireless routers have a default administrator password, which is also known to hackers. With the default SSID and default password can easily view their access to the wireless network.

So, if you set your router, change the SSID and the default password. A neutral name like "my router" is probably the best thing. Whilemay be tempted in a name like "TheSmithFamily" I said, only offers a few more details, trying to get into the system. You know the old joke, right? I'm not paranoid, but even paranoids have enemies!

There is another parameter on most wireless routers, the impact of the name to disable. Some say that you do not want to do this, and it is a waste of time because even sophisticated hackers and "script kiddies" with powerful applications they receive from the Interneteasy to find these "hidden" networks. But disabling the SSID broadcast makes it less objective, as I see it. It keeps the riff-raff!

Second MAC Address

A Media Access Control address or physical address, as it sometimes known is the most unequivocal identification of each network card. The MAC or physical address includes the identification of the manufacturer and "single number". Most wireless routers can do everything with the exception of addresses in your list or in a way thatI recommend you access to all the addresses, but in your list. For the MAC or physical address of your Windows or Linux, you want to help you get a DOS window or command prompt and type:. IPCONFIG / ALL or just IPCONFIG Find the MAC or physical address of the wireless network card. The MAC is 12 hexadecimal digits, separated using the digits 0-9 and letters AF, perhaps a dash or colon. Find the wireless router's configuration screen, which can be used as MACFiltering and enter the addresses of the authorized PC.

Also, do not rest on our laurels. MAC addresses are easily forged, copied or cloned. The router can also be the ability to clone a MAC address to your Internet service provider (ISP) has passed. Why bother? Now again a blip on the radar of someone less. Maybe I'm not too picky, or maybe I'm just looking for someone who is a completely open system must go.

3 WEP / WPA

WEP Wired Equivalent Privacy.And WPA is Wi-Fi Protected Access. WEP is the older protocol. Some call it the weak encryption protocol. Here you will find stories on the internet of this mixture in a few minutes. EPA's new and much more. There is a new version of WPA called WPA2.

To use WPA2, WPA or WEP in that order. If you have problems with WEP? Well, if all that is - yes. It 'better than nothing and may prevent those who want large capacity but not scary hacking encryptedSystem.

You are completely protected now? No, but you are in front of where you were! Sleep a little 'better!

Secure network computer remote access options for remote workers

There are many benefits to offer members of your organization or business with reliable, safe and full of options for remote access. The term "telecommuting" refers to an alternative model of work that employees who work primarily from home or on the move are leading. Remote access options in many flavors. Here are some of the most secure remote access solutions are in use today.

A virtual private network or VPN provides a secureBack link from a remote location to headquarters. A multifunction firewall VPN router or a dedicated server operating system, which includes VPN support should be installed and configured in a central location for an endpoint for VPN remote clients. Internet Protocol Security (IPsec) and Secure Sockets Layer (SSL) protocols are commonly used by VPN services for encryption and security for remote connectivity over the availableInternet.

The one way to connect teleworkers? In most cases, a VPN connection or through the software, which launched on a client computer or hardware based. Support for Microsoft operating systems (XP, Vista and Windows 7) is a built-in VPN connectivity. Cisco, SonicWall, Netgear, Fortinet and many other providers of VPN products to provide all clients and client (sometimes called a thin client), VPN connectivity options.Clientless VPN connectivity is usually through a Web browser with a small Active X control or Java applet in conjunction with SSL to provide secure connection to headquarters. A hardware-based VPN client is usually a router, able to establish a secure connection to your office at home.

Once a remote secure connection is established, remote workers can access what resources are available explicitly. The most common applicationresources and delivery is usually via a server or desktop remote terminal session. Remote Desktop connections, experience, "as if you sit there in the office." Based on remote servers and services that meet multiple users on a single server at the same time to connect. A desktop computer, the remote session is possible, usually 1-1.

Secure remote access from home or on the road to greater productivity and efficiency can be promoted. Movea virtual office employees or teleworkers model also has the added advantage of potential cost savings by reducing the need for the traditional space headquarters.

The penetration tester: Keeping your systems secure

Currently, almost all types of information, including sensitive and confidential information stored in databases and accessed through a computer system. In an ideal world, should be stored digitally in a secure and manage information and given the many ways to access electronic data, such as encryption, restricted network, firewall, etc. However, to protect the cyber-criminals will always find a way to SSL circumvent these walls. So it is always important to have a penetration test andTo monitor penetration testers, dass
A penetration test involves a simulated attack on a network or system for testing in a controlled environment, safety. The penetration tester simulates the activity of an attacker the ability with which the fraudsters real Internet would be able to access the system to be determined. A large part of the penetration tester is the task of finding all the vulnerabilities of the system, what causes them and how to solve them. The task of a penetration testerimportant, especially if the systems to protect sensitive data are involved.
A penetration tester can perform his tests in two species, the black box or white box. If a penetration tester uses a black box, the focus was no information on the infrastructure system. The penetration tester must determine for himself, before his attacks simulated in the analysis. Black-box testing is used when a system needs to be protected from attacks from realThe hackers, who have no knowledge of the system.
On the other hand, the white-box testing, the penetration tester has all the information needed by the system infrastructure. From there, a penetration tester and studies to determine how to attack the system from within. White-box testing is always necessary, in the heart of the system before leaving the hotel safe to store confidential data much more severe in case of a job dealing or a mole.
Some penetration testers alsoplay black box testing that indicates their incomplete information about a system design. This type of test is useful to determine what gives the individual parts of the system, if known, the most vulnerable. Once the penetration tester determines what they are, they may recommend, in particular security measures.
Black Back-testing is inexpensive, because it is completely automated, the work of a high degree of penetration testers. White-box testing costs more because of theWorking in separation of some parts of the system at every step involved the examination. In both cases, the client company is the one who determines which test is best for your system.
Represents a penetration tester Sound interesting? If you are considering this as a career, it is best to get a certification received before the move. The International Council of E-Commerce Consultants (EC-Council, or in short) offers a certification program called "Penetration Tester License" toemerging penetration testers. There are a couple of certification programs of this type, but EC-Council is a program of licensing programs most prestigious and best known in his field.

Protect your business with running a secure server

Although some things are entirely predictable in the business, one thing is certain: At some point your servers and workstations must be replaced or updated. Ideally, these elements can be reconfigured and reused, but eventually all equipment will be the end of his life achieved functional. When this happens, your first thought in the exchange are likely to cost considerations, efficiency, usability and performance. However, it is equally important to decide what will happenYour old equipment when it is obsolete or unusable.

Disposal of old servers and workstations is not as easy as making them on the sidewalk on garbage. Not only do these devices usually contain very sensitive information and private companies, but probably can be made with materials that are hazardous to the environment. And in some cases may be inappropriate for the disposal of equipment in violation of environmental laws. But most companies do notto manage resources in-house secure management of servers and workstations. There are companies that provide professional equipment available, but it is important to be sure, these companies are following best practices.

Top consideration for any company is to protect itself and its employees from data theft. Whether you're using to save the server of proprietary information, corporate e-mail or files, personnel management, data theft can be devastating to see a company's reputation and bottom line. ToPeople often think the deletion of a file means that, for the system, but rarely the truth. Professional Recyclers hardware information wipe out all the servers and workstations through tactics such as software, data-flushing, destruction and electromagnetic the physical destruction of the hard disk. The ideal is to choose a company that not only different levels of data wiping and destruction of parts, but also tracks each piece of equipment through the process so you canensure complete security for your business.

Subsequently, the proper disposal of servers and workstations is essential. First, companies are obliged by law to provide server and workstation in an environmentally friendly manner. Failure to comply with these laws is not only a company at risk of fines and processes can generate bad publicity, in a society increasingly aware of the importance of green living practices. Second, many companies now voluntarily adopt green policiesWay of practicing responsible business and environmental protection. Again, companies can save disposal and recycling of their servers and workstations. However, it is important to first research the practices of this company for waste management. One way to ensure the proper disposal and recycling to ensure that there is available to companies is a member of the e-Stewards initiative. Superintendents and the Initiative is a campaign by the Basel Action Network (BAN), a nonprofit organization focused on reducing toxicaround the world. Ban has received support from around the world by government agencies and environmental organizations such as Hewlett-Packard, HP hardware and HP servers produce. The members of the Superintendents and-Initiative, BAN, following all e-waste laws, practice and practice environmental and social responsible recycling.

If your servers and workstations will reach the end of their usefulness, do not forget to treat it with consideration what iswould be new equipment. Even if they are out of sight, do not put out of mind as their proper disposal or for the security company continues.

Secure e-mail client are important in today's world

Whether you are an individual or head of a large company, communication is one of the most important aspects of your business or personal life. When communicating via computer, the most important method of connecting with other e-mail. An e-mail programs or e-mail client and it works for us to send and receive communications to and from our contacts. All these programs use when setting up an account. Most of them work very well. However, not many of these programsessential to protect and securced. With an e-mail client is certainly very important for us is today's time.

Everyone at one time or another requires contact with their communication. When information about certain things were accessible to anyone who wanted to find, it could well lead to problems. For example, if you are a business that should be monitored until the band is ready, so word of it may leak to the public can be devastating. This iswhy a secure email client is essential in today's world. In fact, you often hear about where the bank fraud or other information obtained and used for the high cost of the victim. All this can be avoided by mail client with a safe e.

Many people have firewalls and antivirus protection on your computer and can not recognize that the client is important for secure e-mail. Every aspect of sending and receiving messages that must be protected,and it is good to know that some email programs are very willing to do so. Using different levels of protection to make it difficult for anyone to e-mail hack. A password key is required as a security measure primary and individual e-mail can be protected with a password.

In addition to passwords, to ensure the quality of the mail client is an encryption of all data stored. Powerful keys are designed to protect private data. Knowing thatprotected by a secure e-mail client gives you peace of mind as to send and receive data over the Internet.

Wireless Network Security - Basics of a secure wireless LAN

Authentication process network

The process of a partner and client authentication is an access point by default. If Shared Key Authentication Client selected indicates that there are add-on packages sent to confirm the authenticity of the keys.

The following section describes the EAP authentication on the network.

The probe sends first customer at all access points

2. AP sends frame information with data transmission rates, etc.

Third Clientselects the next combination Access Point

Fourth scans client access point, in order of 802.11a, 802.11b, 802.11g and

5. Data Rate Selected

Client Associates sixth SSID Access Point

7. EAP authentication on the network, client authentication with RADIUS server

Open Authentication

This type of protection is a string to an access point or multiple access points defines a logical network segmentation known as wirelessService Set Identifier (SSID). The client can not connect to an access point, unless it is configured with the SSID. Connecting to the network is as simple as determining the SSID of each network client. The Access Point can be configured to not broadcast the SSID to something better security. Most companies implement static or dynamic keys in order to integrate the security of the SSID.

Static WEP

Configuring the client with an adapterStatic Wired Equivalent Privacy (WEP) improves the security of wireless transmissions. The access point is configured in comparison with the same 40-bit or 128-bit key WEP and association during the encrypted key. The question is, hackers can intercept the wireless packets and decrypt the WEP key.

Dynamic WEP (WPA)

The use of dynamic WEP encryption keys for each session reinforces the security of a hash algorithm, the new key pairs generated with specificIntervals to make it harder to spoof. The protocol includes methods for 802.1X authentication with TKIP and MIC. Authentication between the wireless client and RADIUS server authentication allows proactive management of safety. It should be noted that any type of authentication must be given in support of the Windows platform. One example is the PEAP requires Windows XP with Service Pack 2, Windows 2000 with SP4 or Windows 2003 on each client.

L '802.1x is an authentication standard per user, per session encryption that supports EAP types: EAP-TLS, LEAP, PEAP, EAP-FAST, EAP-TTLS and EAP-SIM. User network authentication credentials have nothing to do with the configuration of the client computer. Any loss of computer equipment does not affect safety. Encryption is TKIP with advanced encryption standards WEP treated with improvement of the packet key hashing (PPK), Reportintegrity check (MIC) and broadcast key rotation. The protocol uses a 128-bit key to encrypt data and 64-bit keys for authentication. The transmitter adds a few bytes or a MIC package prior to encryption and the receiver decrypts and verifies the MIC. Broadcast key rotation rotate unicast and broadcast keys at certain intervals.

How to set up a secure proxy

The need to establish a secure proxy is created when a computer can not directly to a desired network. This may be due to the fact that the safety requirements is not sufficient for direct connection, so you may need to function as an intermediary to act on your behalf.

Secure Proxy can also be chosen so that the firewall administrator for access to inappropriate web sites. In some cases Secure Proxy is accessed as a fast connection, too oftenLocations. These are used to accelerate access to Web sites that are visited constantly, and keep an unwanted sites. Computer connects to the Internet through a single IP address, such as Local Area Network (LAN) works. Since not pass data through a series of gates, the data is secure.

The proxy settings actually differ from the firewall, since the application level, the 7th layer of the OSI model to use as a firewall to use the lower layers. Setting up a secureThe proxy requires platforms other protocols such as the firewall, and it is therefore difficult. The proxy server must be customized for the proper functioning of a number of applications, such as HTTP, SMTP, SOCKS or configured. Only a well-configured proxy server will work in a safe and smart to check outgoing requests whose URL addresses, and make routine, HTTP GET and POST messages.

This allows administrators to grant access either in cash or other sites. In contrast WebsiteDomains in the news not to read through the firewall. Proxy servers also filter content within the application of information received. In many proxy server for Windows, set a secure proxy can be guaranteed if you do your due diligence and check the reviews first.

Use a proxy server, such as the above WinProxy, a transparent proxy server with NAT and supports all protocols including HTTP, FTP, NNTP, etc. any other software installed on our computer,thus to accelerate the development and efficient operation of servers later. In addition, the proxy client is not recognized by computer. Because of this the client computer is virtually nothing about proxy 'server existence.

Setting up a Secure Proxy Server as WinProxy requires some simple configuration steps. First, it requires the TCP / IP on the network computer to install, and then select the Setup Wizardwill guide you through the installation. To activate the wizard, the product keys are required. Select your Internet connection and the name of the selected connection.

The method is then as simple as access to all of your Internet connection: After selecting your Internet connection, you must type your username and password for the same. External and internal configuration of IP is that, as a single address automatically given to all devicesLocal area network (LAN). Now disconnect the Internet, and navigate to the last stage, when WinProxy, confirming through the entire setup following successful implementation of all configurations. Now, the Secure Proxy is available for use. Although the creation of a proxy is difficult to secure, protect your data.

To configure SSH (Secure Shell) for remote access to a Cisco router

the introduction of Cisco IOS SSH, Telnet remote login protocol only makes. Although quite functional, is a non-secure Telnet protocol, in which the entire session, including authentication, are unencrypted and therefore subject to snooping.

SSH is both a protocol and a software which replaces Telnet and provides an encrypted connection for remote management of a network device like a Cisco router or switch safety device.

L '> Cisco IOS provides an SSH server and SSH client. This document is only with the configuration of the SSH server component concerned.

Terms

Software

The server component requires a photo SSH IPSec (DES or 3DES) encryption software from Cisco IOS version 12.1 (1) T or later installed on your router. Advanced IP Services image includes the IPSec component. This document has beenc2800nm-advipservicesk9-mz.123-14.T5.bin.

Preconfiguration

You need a host name and domain name of your router. For example:

Router #
Router # conf t
Enter configuration commands, one per line. It ends with CNTL / Z.
router01 (config) # hostname router01
router01 (config) # ip domain-name domain.local

You also need an RSA key pair for the router, which automatically enables SSH. In the following example to determine how the key pair is designatedCombination of host and domain names that have been previously configured. The module provides the key length), the key length. Cisco recommends a minimum key length of 1024 bit (even if the standard 512-bit:

router01 (config) #
router01 (config) # generate RSA encryption key
be the name for the key: router01.domain.local
Select the size of the key module in the range from 360 to 2048 for General Purpose Keys. The decision to form a key larger than 512, a fewMinutes.

How many bits in the module [512]: 1024
% Generating 1024 bit RSA keys ... [OK]

Finally, you must authenticate to a server such as RADIUS or TACACS + AAA server or local user database for remote users and enable authentication for terminal lines. For the purposes of this document, we create a local user database on the router. In the following example the user "donc" has been a privilege level of 15 (maximum) was created and received aencrypted "p @ ss5678" password. (The "secret", followed by "0", the router says the following password to encrypt the plain text. When configuring the router is running, the password is not readable.) We used the line configuration mode to tell router use its local user database for authentication (login locally) in the terminal lines 0-4.

router01 (config) # username privilege 15 secret 0 donc p @ ss5678
router01 (config) # line vty 0 4
router01 (config-line) # loginLocal

SSH enabled

To enable SSH, you must use a key pair for the router. Alternatively, the version of SSH (the default SSH version 1), the timeout values for authentication, and some other parameters. The following example uses the router to the key pair you created earlier and use the SSH version 2:

router01 (config) #
router01 (config) # ip ssh version 2
router01 (config) # ip ssh RSA key pair name router01.domain.local

You can now access the applicationMake sure your router, an SSH client as TeraTerm.

Display configuration and SSH

You can use the privileged mode command "ssh View" and "ip ssh to view SSH connections and configurations (if any). SSHv1 The following example configuration of a Cisco 871 is verified with the" show ip ssh "and a SSHv1 individual content is displayed to show ssh "with". Please note that we do not allow SSHv2 on this router, making it the defaultSSH version 1.99. Note also in the production of "ssh show" command, the version 1 default 3DES. SSHv2 supports AES encryption technology robust and efficient. SSHv2 is not under the same vulnerability SSHv1. Best Practice recommends using SSHv2 SSHv1 and off at a drop-back. Enable SSHv2 SSHv1 disabled. This example is to demonstrate compatibility only:

router04 #
router04 # show ip ssh
SSH Enabled - version1.99
Authentication timeout: 120 seconds; authentication attempts: 3
router04 #
router04 # show ssh
Connection Version Encryption State Username
2 1.5 3DES Session started donc
% No SSHv2 server connections running.
router04 #

You can also use the command "debug ip ssh SSH configurations to solve.

optimal use of authentication with SSL VPN Secure Auth

If you are using Cisco or Juniper SSL VPN network access by allowing your company to final consumers Secure Auth is an excellent companion to ensure a secure seamless connection by end-users across the enterprise server and back to your clients your current SSL VPN authentication connection to the Internet.

The process to access a corporate network via remote access can lead to serious security risks that cause moderate to large end-user downtimeTraining. This endangers the entire infrastructure of a network, but a necessary component of a well-functioning society, as it is almost impossible to have all put consumer mainframe 24 hours a day.

Auth for Cisco Secure VPN authentication is a browser-based, bi-directional authentication solution X.509 certificate Cisco IPSec and SSL VPN, Cisco. It works directly with the current device Cisco ASAa complete solution to provide authentication safer place. This solution offers several advantages over its competitors. It does not require a token, data, server or additional investments in infrastructure, not a private company in the Secure Hosted Auth saved infrastructure. It eliminates the need for an administrator to install and update software for the end user and very user-friendly auto-registration and automated distribution of certificatesreduced help desk calls. If this is not enough, it also supports IE, Firefox and Safari.

Secure Auth also integrates seamlessly with the Juniper IVE provides browser-based, two-way authentication solutions that require X.509 certificate authentication level, This allows the Cisco VPN. A transition seamlessly from Cisco or Juniper Secure Auth without significant reinvestment. The Juniper version differs from the version of Cisco forthe fact that the multi-platform support for Windows, Mac, iPhone and Linux clients.

Secure Auth is scalable to meet the individual companies, offering a complete range of services for the adaptation of the Secure Auth for the needs of any business to attend to. This provides extra protection, not in recent time. As a hacker and vulnerability are still widespread and very dangerous, Corporate Security, is always very important that the software is safethat an additional protective layer. This allows the integration of remote users, enabling greater productivity, protecting the network from those who should not have access. It also helps to limit the number of help desk calls to correct on integration, contribute to the cash cost per user of IT services more productive and cost-effective to reduce the company.

Security certificates - easily on your site and increase conversion rates Secure

The Internet is a market with thousands of products and services from around the world. We need to find some comfort in seconds simply by typing words and scanning through the mail. When Internet access was common to all, family e-commerce and online shopping is a trend. Therefore, any Internet user a potential buyer or customer. But for an online shopper, the first thing that comes when you enter an e-commerce in the sensethe question: "Can I trust this site ... Is there any type of security certificate?"

Remember, trust is necessary in a sale. The advantage of an online business is access to all our customers around the world 24 / 7 and less costly maintenance and operation. However, one of the disadvantages that their presence online, customers can call into question the legitimacy of the company and the quality of its products for lack see it in person. AnotherIntroduction threat is that customers feel free to disclose personal information for fear that there will be safe and disseminated. In addition, customers may be careful to disclose financial information because of the fact that the alarming cases of widespread identity theft and credit card fraud.

The good news is that there is a simple, security threats that may 'lead to increase in order to eliminate the exchange rate. To get a better business online throughTrust and confidence. The harsh reality is that you lose a potential sale in a few seconds before, when the customer feels that your site is not secure and can not be trusted. A proactive task is to beat the truck, they show a sign or signs that your company's web site is security.

Secure Sockets Layer Technology or SSL protocol was developed to protect online transactions from financial and personal information. As a result, they have safety certificates are currentlyTo show condition for e-commerce sites, because it acts as a visible proof and passport, the online business that is legitimate and sensitive information safe from hackers or unauthorized use. Security certificates work by authentication and encryption. Each browser is SSL certificates and if the client computer requesting the certificate for authentication between the browser and find the site. If your site uses a security certificate, ayellow padlock appears on the bottom right of the screen. Overall, a security certificate is a win-win situation for buyers and sellers. This will give customers a reassuring certainty that transactions will be safe. On the other hand, the seller is therefore an increased conversion rate (visitors online shoppers turning) - increased revenues could mean an increase in ROI.

Configuring Secure Shell (SSH) for remote access to a Cisco router

Before the introduction of the Cisco IOS SSH, the only remote login protocol has telnet. Although quite functional, non-secure Telnet is a protocol in which the entire session, including authentication, is in plain text and thus subject to snooping.

router01 (config) # line vty 0 4
router01 (config-line) # loginlocal

Enabling SSH

To enable SSH, you must tell the router to use the key pair. Optionally, you can use the version of SSH (default SSH version 1), authentication timeout values, and some other parameters. In this example, we told the router to use the key pair created earlier and use of SSH version 2:

router01 (config) #
router01 (config) # ip ssh version 2
router01 (config) # ip ssh router01.domain.local RSA key-name

You can now accessSecure your router, an SSH client as Teraterm.

Information Technology Forum for secure networks

VPN provides secure access to integrated data and that's for sure. The most modern technologies of the computer as a VPN have a system owned or leased lines, VPN know that the organization was less expensive than might only be an organization that provides the same functionality at a very low cost.

A VPN works by using shared public infrastructure while maintaining the confidentiality of security procedures, such as Layer Two TunnelingProtocol (L2TP). These tunneling protocols to encrypt and decrypt data on the sender and the receipt page. A "tunnel" is created that can not be "entered" a compromise between them. A further level of data security is not just data encryption, but encryption of origin and receiving network addresses.

You may request technical assistance for the creation of a VPN in a good forum for information technology. This is a technology-intensive process that can give great rewardsYour system activity. You can set up and configure a VPN with Windows 07 and Windows 2008.

In the long term, VPN technology can reduce operating costs.

You have to follow some effective tactics for best results. Your expert technical assistance in a forum good technique, you can help it. Today, VPN is a useful tool for SMEs. Given the growing advanced technology Web 2.0 Internet and globalization, the practice of recruitment of remotequickly. can spread using the services of labor in different geographical locations will significantly reduce the costs of doing business and competitive advantage.

You can hire workers worldwide talent for your business. Through the use of appropriate technology VPN, you can ensure that the confidential data of your company building the house are safe. In fact, VPN is a promising option for midsize businesses.

You need special hardware andSoftware before creating a virtual private network (VPN) for users of Microsoft Exchange Server remotely. You can find a study-based information forum for peer-to-peer solutions on different Virtual Private Network on different network protocols. This will help you determine the best solution and the encryption system for your specific needs.

Secure Proxy

Secure Proxy acting as intermediaries accepting applications for other systems and thus contribute to others in the order given. These are often used when the network connecting the client computer is incompatible with a direct. An example is when the customer needs is not able to take the security of the server.

Secure Proxies are also used for screening purposes. This allows access to inappropriate web sites contain unwanted or administrator. In addition, the Secure Proxy ServerAlso used for cache, faster access to frequently used Web sites.

Key Features

These types of proxies are working on the application level - the seventh layer of the OSI model. Unlike firewalls, which work differently in the lower layers tend secure proxy, to remain dependent on demand.

These types of proxies are easy to install and are very difficult as a firewall, just because the functionality for each protocol is configured on an applicationTime.

However, increased well-configured secure proxy performance and security. work with proxy servers for OSI application layer, the filter questions are very sharp. Through the control messages, web proxy server can easily verify URLs outgoing requests for web pages.

VoIP secure?

The service provider offers VoIP security as follows. You want to ensure that their network is secure, their revenue with their customers protected. If you do not have to VoIP, the false sense of security that everything is good VoIP. Also understand that you're not in a position of a call anywhere. Even today, VoIP still has some problems of reliability and security, said that these problems are addressed because of increasing demand fromthis technology.

As we know the broader question of security is a hot topic these days and off the Internet, following the security industry, governments and global standards, so we can expect some control serious security problem facing VoIP. VoIP is also vulnerable to security risks as traditional IP data networks or other data that are sent over the Internet.

As hackers use to infiltrate a software with security holesThe transfer of data, it cam also use the same software to your voice to get the data. Although this may not be a big problem, if you're talking to you baby from the field, the opposite is true in the case of sensitive data during operations.

Ensure that if you are considering a VoIP provider, is offering security and redundancy, so that you do not have to worry about the physical requirements and support your phone system. Secondly, they want to address these problemsSecurity. Ask them if they have separate lines for voice traffic. Ask them what steps to take to protect their networks. You can also ask if you can combine a VPN (Virtual Private Network) for your VoIP? This can prevent unauthorized access to telephone system

Moving into the future VoIP security will remain an important concern, because it is well known that the information that passes over the Internet may fall into the wrong hands. As much asIt 's always a concern, as well as additional resources were devoted to these gaps in security issues. You've put many questions and get the best possible service for your needs.

Decide to go, with truly wireless Internet in the new year

When it comes to ringing in the new year comes, it is seen as a time of renewal and new beginnings. People want to go see, come to the new and the old ones. They make resolutions, some promises to himself and others that this year will be fresh and new, filled with ambition and efficiency. For many of these resolutions to several months paid stacking an unused gym membership, one of unread books, and some quit-smoking-candy that seems to never make it out of the box amount. For others, thisYears can be a great opportunity to really improve life. A good start may be a subscription for a 4G WiMax Internet service.

Everyone wants to streamline their lives, and spend more time on things they enjoy. This can include everything from a bird-watching or sailing hobby to spend more time with the family. With the Linksys Wireless-quality fourth-generation wireless Internet really can help accomplish each of these acts and more. By Internetwherever you go, it is possible to get out of the office for your lunch break without losing time, it is a good way to work by bus or train to do, and it allows you to bring the office home, so any little emergencies sans to the long hours or emergency trips back to be dealt with in the boardroom. Streamlining a business and private life to be more efficient, and therefore more quality and quantity of time is a top resolution of the wish list of many.

For those puttingGetting into or back into shape at the top of the list of resolutions, a great incentive that the treatment of your workout routine to a brand new MP3 device. With a subscription of WiMAX Internet service and activate an MP3 device, 4G, not only listen, but actually download music while jogging. Eliminate the middle man and download movies while in your car, and send photos and videos from your digital camera to friends and family immediately. Skip the step where you can then download for hoursUploading send you, and stuck all the time and energy into a workout routine!

Finally, for the person who wants only happier, more relaxed, and far less stressful to start this year is a great place with a WiMax ready portable handheld or mobile phone. The current 3G technology is great, but it does not just give users the mobile broadband capabilities of the fourth generation or 4G technology. By sending and receiving video, large files and important documents are on the go thereis far less stress in cramming everything involved in a work day, or a few free hours at home. The bottom line is that today people constantly on the go. Unfortunately, the Wi-Fi technology is almost impossible to keep our way of life. to be efficient, and therefore free, people have to work with the technology and to dictate what they will do for their technology to, rather than prescribe the possibilities of the technology they already have, how they live their lives.
