Sophos joins Cisco's NAC program

Sophos PLC said Thursday that it will participate in Cisco System Inc.'s Network Admission Control (NAC) client security program.

Antivirus software company Sophos said on Thursday that it is joining Cisco Systems's Network Admission Control (NAC) program, according to a statement.

Sophos will integrate the Cisco Trust Agent (CTA) into Sophos Anti-Virus. Sophos is the latest antivirus software vendor to participate in the NAC program, joining Computer Associates International, McAfee and Trend Micro in supporting the program.

Announced in November 2003, the Cisco NAC program is part of Cisco's Self-Defending Network strategy. The program allows Cisco routers to evaluate client security information, such as whether a particular computer's antivirus definitions are up to date, before allowing it to connect to a network. Machines that don't adhere to network security policies can be denied access, quarantined or allowed only limited access to network computing resources.

In joining the NAC, companies such as Sophos modify their products to communicate with the CTA, which is installed on laptops, home desktops or servers, or mobile devices that will be connecting to a computing network. The CTA collects information from other security software clients including antivirus clients, and relays that information to Cisco devices on the network.

In October, CA said it would integrate the eTrust PestPatrol Anti-Spyware and eTrust Antivirus products with the Cisco Trust Agent.
