Digital communication in connection with the use of modern Internet have exponentially to the point that communication has become digital now an indispensable part of daily life. From mobile phones to netbooks to e-mail, blogs and online portals, the transfer and exchange of electronic data, communicate as many controls interact with each other both personally and for business travelers. Now with the current trend towards "cloud" computing, where all persons or companiesKeep important documents stored and accessed online or in the "cloud", cyber security has become the number one priority among many.
Protecting methods to data in encryption, anti-virus were software, firewalls and passwords to access long before the current information revolution, but unfortunately not such as to accommodate effective security solutions to the modern forms of digital communication. Products, the global data network or Internet connection can produce, havegetting smaller and smarter. For example, with only a modern mobile phone, a person's e-mail, post updates on blogs access and access personal or business documents that can be all over the internet.
The typical security approach in the past has been on the model to identify the access via firewall systems or intrusions as virus signature scanning systems. All these solutions are based on the concept is based, restrict, channel hide, and access toData. A firewall, for example, borrows its name from the "fire-retardant walls" that must be established to secure areas where no fire because the material may, from which they are built to pass. In this case, all external access, which was not previously considered necessary, an internal or public network blocked as fire and simple. Anti-virus solutions, and the virus signature model also proved to be defective, because the turn around time for the signature files and the amount of changeResource utilization of these systems to scan 1000 of files. It's like the concept of sending the police to everyone's house in a city of millions of people are trying to figure out where to hide the bad guys. With modern computers with multiple 1000 files, and the ever-changing nature of modern fast polymorphic viruses on the signature-scanning model is no longer feasible.
The problems with current approaches, with the proliferation of digital networks, there has neverwas a way to accommodate the dynamic updating of firewalls or signature databases to new types of access and threats. Almost every day there are new applications, which themselves are always necessary for people to gain effective access to digital services and also new dangers. The current security situation model was never considered a solution that quickly finds work between good and bad. In fact, it is the freedom of the entire group to protect the potentialThreats of a few. A truly useful security system must be able and get access to the group and then only in limited or denied access to these activities out of line with the established standards of operations.
Each brings with it security technology, property and general firewalls, antivirus software, a cost, VPN networks and access control methods rather serve to limit the access to modern digital networks, to protect as effectively. System administrators andCorporate IT security directors can no longer follow restrict and mitigate model everything that is there in the end they only legitimate access is extremely limited and the ability of users to take advantage of the digital information revolution and does little to actually " to prevent hacking or unauthorized access to their networks.
A truly effective cyber security solution is as dynamic and flexible as the guests of every-changing applications and digital servicesAccess and digital equipment used. It is no longer a workable model to restrict it all, or scan everything because it serves only to users, taking advantage of increased productivity and performance by modern digital networks and the Internet brought obstacle and an enormous use of computing resources.
The cyber-security model for data networks can be something that protects data and systems through the denial of access to unauthorized users defined, preventing downtimeservice authorized by unauthorized activities (Denial of Service attacks), and the preservation of the entire area of the health status of a digital network at 99%.
1) The protection of data and systems from unauthorized access
As more and more online information of the financial information is stored credit card numbers, classified documents and information that has not fallen into unauthorized hands, the privacy of the biggest concerns of Internet security. Unfortunately, it has manyknown vulnerabilities of critical data, like millions of stolen credit card numbers, theft of company trade secrets and even concerns of foreign retrieve information of national security through the use of Trojans and other intrusion methods.
Methods for intrusion contain
The installation of backdoor network intrusion applications, or disguised as legitimate applications that are accidentally caught in a network of authorized users to open infected e-mails or use hiddenSites.
Brute-force attacks, which are common user names and weak passwords used by schemes that seek millions of combinations of user names, sets the password to gain access.
Exploits can be found in operating systems like Microsoft Windows, a secure or an authorized service used by errors in the software design.
Theft or breach of the internal networks of employees or persons authorized by a rule allowing access to the systems, or who has access to certain areas to keepinternal snooping, where they will be able to find passwords and authcode safe areas. (Notes on the desks on the left to back left of computers to areas notified.
Exposing the data to an external breach by documents on USB pendrives and laptops to present these data at meetings outside of the network. Many times people place the document on a USB pen, which have for a presentation at a different location, but they happen to secure documents regardless of the current session, theleft standing on the USB. Then they have their pen drive into your computer to a third party to submit by 1 document, without knowing that it is mainly computer a Trojan, fast, all data copied to the USB 3 Party to an unauthorized location.
2) prevention of downtime of professional services by non-authorized activities
Brute-force attacks, scanners, and denial of service attacks can have a network, the main server and its access router to get to the point that theNetwork is no longer usable in any form. Such attacks cause considerable damage and downtime to the network on a daily basis. The ability to detect such attacks and to cut them off at the source furthest away from the core network and its services is very important for the overall health of a strong cyber program.
3) The preservation of the general functional state of health of a digital network.
The preservation of the health of a digital network is not only in the prevention of attacks andaccessing unauthorized activities, but also in the maintenance of centralized services and data, depending on the authorized user. It is not a viable solution to stop an attack or to prevent possible attacks by also prevent or limit unauthorized access. A cyber solution to be able to isolate and prevent attacks and injuries, his integrity, not by limiting the same time, or the denial of access to their resources by unauthorized users.
It is clear from the many different ways that the securitycan be violated in data networks, and overwhelming dependence on such networks, the current security methods are not only no longer sufficient to protect such networks, but even serve to further problems and create more security network access problems. Created as an urgent need for the current mode of approach to cyber-change and a new dynamic model that is able to constantly adapt to the changing needs to provide the protection of data networks.
A new model must IDSbe created to meet the following objectives:
The goal of any IDS system must ensure the integrity of the network, in which they protect and accept that to receive such network in its ideal operating at 99.99% function. An IDS system to be used more easily and dynamically. An IDS system may not prove to be another break-in and can not break the first rule from the networks integrity too much computer and network resources in their efforts to protect theNetwork.
An IDS system must be able to be permanently on a constantly changing environment and adapt itself added his own signature on the basis of documents relating to the evolving threats. An IDS system should not require hands on a lot of resources to continually update their signature files, and manual verification requires that the threats that they are actually incurred are recognized and not false. An IDS system must be able to simultaneously protect the network against attacks from unauthorized use and prevent downtime, no, nor to limitnetwork access and usage of network resources to authorized clients. As such it must always discreet and maintain the network in an open state in which are entitled to its core services and resources, 99.99% in the networks, the user as well as the identification, isolation and prevents unauthorized activities.
Really only research in proactive defenses will keep the protection of the usefulness of digital networks of today and tomorrow.
