The most recent annual virus episode is networked, and the transmission path is through the network, and the two is destroyed is also for the network. It is still normal to operate when the episode is normal, but the entire network is paralyzed. This is the difficulty monitoring of Norton, etc. on. Cisco has begun to consider the development of security issues as the development of network equipment (previously the first performance).
Network devices can make it a great advantage in preventing network viruses, with the virus network, Cisco changes the security field into a new growth point. In this change, the victim is probably Norton, and the prospect is worrying.
