Cisco also added a distributed-threat mitigation feature for intrusion-prevention systems to version 4.1 of its Security Monitoring, Analysis and Response System software. That feature gives routers along the edge of a network a heads-up to a security threat, letting them automatically drop infected network traffic.
And Cisco revealed details of the new versions of its Intrusion Prevention System and Cisco Internet Operating Systems Software Release 12.4(4)T. The new IOS, due in November, includes a capability that lets administrators conduct deep-packet inspection pattern-matching and filtering to help them respond to an outbreak without network service disruption.
The announcements come less than a month after Cisco issued a fix for a notable security flaw in its Internet Operating Systems. The company is "struggling with the same security problems that all IT vendors are struggling with," says Greg Shipley, chief technology officer of security consulting firm Neohapsis Inc. The question is whether it can manage those struggles as it distributes all its acquired technologies throughout the world's networks.
