Infections from worms such as Blaster and Nimda are frequently traced back to mobile or remote workers; their PCs are less likely to have AV protection and up-to-date security.
In its initial phase, Cisco’s Network Admission Control technology will enable Cisco routers to enforce access privileges when an endpoint device attempts to connect to a network.
Software called Cisco Trust Agent runs on endpoint devices to determine their security state and communicates this information to the connected Cisco network where access control decisions are made and enforced. The program is described by Cisco as a key development in its Self-Defending Network Initiative, the networking giant’s strategy of integrating security services throughout Internet Protocol (IP) networks.
In future releases, this capability will be extended across multiple Cisco product platforms, including switches, wireless access points and security appliances.
