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. Often infections from such sources break out long after the initial viral onslaught.

To minimise this secondary infection threat, Cisco is developing a network admission control system designed to enforce tighter security policies.
