Integrated Network Access Control Solutions

With many elements in cyberspace threatening the security and the very survival of businesses and organizations, security measures need to be enforced to safeguard different networks. One of these measures is network access control (NAC), which is a form of computer network security that unifies endpoint security technologies. Also known as network admission control, NAC encompasses user and system authentication and network security enforcement.

The NAC system restricts the type of data each user can access. For instance, the traditional network access server (NAS), a component of NAC, performs authentication and authorization functions by verifying password login information. Companies that offer NAC solutions can build upon the client’s existing security network infrastructure to reduce the need for additional hardware or firmware. The NAC’s enterprise management solution ensures that employees can log on to secure networks without having to remember or even type complicated or rudimentary passwords.

Efficient NAC solutions combine password management software and card management with secure smartcard technology. This improved solution easily integrates into existing networks, and requires no backend server modification. Unlike other security products which force managers to modify their network control policies to adhere to the security product's architecture, improved NAC solutions can be easily configured to comply with the company's network access authentication policies.

Improved NAC solutions can be used to log in to access points, such as network servers VPN, intranet and extranet, and the Windows OS logon active directory. Improved NAC solutions also reinforce security despite the challenges posed by virtual servers.
