Network Access Controller (NAC)

Secure Network Access

Product Overview

Multi-Vendor RAS Support with RADIUS, TACACS, TACACS+, ACE, SGLOGIN security servers all in one. The Network Access Control (NAC) System provides extensive remote network access security for IP networks

What is the NAC?

The Network Access Control (NAC) System provides robust authentication, access control, auditing, accounting; source and destination filtering and IP pool management for IP networks. The NAC architecture is capable of supporting large networks and well over 1,000,000 users per system.

Datatek Strong Authenticator (DSA)

For the NAC, Datatek Applications introduces a new, exclusively software-based, authentication method that obviates the need for smart card or hand held one-time password generators.

DSA transforms the smart card approach into an inexpensive approach. The software-based authenticator or DSA generates a one-time password on the user’s PC. Use of this one-time password along with a user pass code and user-id provides for strong user authentication

Each one-time password is unique and valid for the user who generated it. Reuse or re-transmission of the same password by the same user or anyone else is rejected. In the case of password re-transmission, the call is not only rejected but the network security administrator is alerted to the attempted use of a previously captured password.

Features

Multiple Security Protocols

The NAC has extensive security protocol support for remote access management functions. Some of these protocols are ACE, TACACS, TACACS+, SGLOGIN and RADIUS.

The NAC System provides extensive remote network access security for IP networks.

Running on the multiple hardware platforms the NAC provides a rich set of features including:

• Highly available support for large networks
• Strong access control
• Myriad reports
• Extensive protocol support
• Complete system administration.

The NAC thwarts invalid network access attempts with its robust set of security functionality insuring that any network is secure from remote user access threats.

All users who access the network are not only strongly authenticated but can be profiled differently, with our user level security implementation, allowing for more finely controlled network access.

Effective and efficient security is provided for dial-in users using high-speed modems, DSL, or cable modems.

The NAC boasts a convenient, administrative user-interface (JAVA based GUI technology) accessible from any browser after strong authentication.

The security administration of the entire network is centralized whereas authentication, access control, auditing, and many other user level functionalities are distributed for scalability.
