NAC 2.0: A new model for a safer future
NAC functions best fit on the end point. We must be about the present scenario in which users control the conduct NAC website as a part of effective security. How bad is it? We found that 40% of the respondents had begun the use of NAC, but completed only 4% actually.
The majority of those that are based search for solutions to network equipment such as devices, Ethernet switches, routers and VPN gateways are over. But we believe that this approach is wrong.
NAC 1.0 and why it does not areOrganisations increasingly on technology, Network Access Control to provide better protection of their networks and their data. However, many first-generation NAC 1.0 “solutions on a fundamentally flawed model that does not respect the competence and responsibility of different groups within the organization. NAC 1.0 was not responding quickly enough to protect against the rapid evolution of threats or the needs of an increasingly mobile workforce address.
NAC NAC separated from 1.0 to 1.0 generally has been cut property levied by a struggle for control between the two main teams, two different perspectives:have the network team perspective – guest access. The network team interpreted “network user ” in this sense a means of control or user block unauthorized access to the network.
> The Desktop team perspective – Managed Endpoint computer. NAC 1.0 – focus on customer lock <> client access was an easy target for many products in the early NAC 1.0, with access generally considered as a luxury and not as a business necessity, and often necessary in certain locations such as conference rooms. In addition, customers often do not have a formal relationship with the company and are not part of the organ systems of identity management, such as Microsoft Active Directory. It was just enough point solution for many devices, a mechanism to computers of customers until they are brought in line with policies of the Organization block. However, NAC convened 1.0 focus on the goal of the Network Access Control teams missed a much bigger problem in terms of the security of an organization, namely the much higher risk of devastating losses, data from a managed computer setting configured incorrectly. With few exceptions, such as academic institutions, ie the large number of managed computers criterion they have a much larger surface area, the threat actually makes a much greater risk.
NAC 1.0 –the first generation of NAC solutions do not recognize that the threat is constantly evolving, to new threats and vulnerabilities emerging every day. publisher of anti-malware, a steady flow of updates to detect and eliminate new threats. operating systems and application software vendor security patch problem on a daily basis.
user NAC 2.0 : A new model for ensuringMany NAC products could not easily updated to allow for updates. If a seller is an update or a new version published anti-malware, the administrator had often the valuation rules update manually. With the new operating system patches, administrators tend to a new complex of the corresponding registry entries set to give to each new patch for each operating system – if the tools of the NAC approved the assessment on all of the patch. The great burden for to keep the current rules means that the assessment tools NAC far behind the actual risks to which companies.
Some NAC products were first Intrusion Prevention System (IPS) is based which an abnormal network behavior seemed. These threats were helpful was often network with recognizable signatures. Today’s threats are often invisible to behavior-based IPS in this case, there is no identifiable network anomaly.
Network Devices Some NAC vendors to deliver their solutions as network devices. It was a choicefor their own convenience, not the needs of their customers . have by providing a device managed to conduct their tests in order to limit a small amount of given platforms. This convenience is obviously misleading. The networks often have to be revised for a device to all traffic on a choke point and reduce the efficiency reliability and add funnel. NAC devices also lack the capacity for a thorough evaluation, good scalability and ways to computers, to protect them if not connected to the network.
< Network Equipment / strong> Network providers are generally in improving the switching and routing gear to the latest features are interested. You do not have a good presence on the endpoint and further attempts to access the network with devices and machines only failed because it the low score and offers little or no management policy. NAC Network ignored the question of remote or mobile users, but ironically has its roots in the NAC Host Integrity Checking for roaming users. NACThe original NAC frameworks – such as Microsoft Network Access Protection (NAP), Cisco Network Admission Control (NAC) and the Trusted Computing Group’s Trusted Network Connect (TNC) – offered basic standards for interoperability and a little more. They provided some pipelines, but has left organizations in order to process the job do it all together. policy management, updating and auditing have been out of the equation.>
The future of the NAC
As already mentioned, the network team, where many originally NAC solutions kissed and it seemed natural for this team, the main owner of the “Access Control system”, although the NAC is actually more than just the network. The team includes experts on:
/ p> Virtual Switching (VLAN)
The network team needs NAC to the computer, unknown or dangerous effects on keep the network security, availability and performance.
NAC team needsThe office team is concerned with computers and manages all aspects of its configuration – even when not connected to the network, for example, homelessness.

Although it does not depend on the daily operational responsibility for workstations and network, it sets standards throughout the organization. Some practices are from state regulators, such as HIPAA (USA) 3, PIPEDA (CA) 4, BS7799/ISO27002 (UK / int ‘s) 5 charged with, while some bodies recognized in the industry such as the Center for Internet Security (CIS Benchmarks ) 6 and the Payment Card Industry (PCI DSS) 7

The approval of this policy results in more quickly to information in real-time security updates.
