Cisco says attacks are due to operational practices

[Sean Donelan <sean () donelan com>]

In an InteractiveWeek article the head of Cisco's security products group
says the attacks are an operational problem not a technical problem.

> Routers from Cisco and other vendors have the ability to detect the signature
> patterns of a denial-of-service attack, and the routers can filter out that
> traffic, Farnsworth said.

> "The router knows which sources are legitimate or not and drops on the floor
> anything suspicious," Farnsworth said. "Generally speaking, ingress filtering
> and committed rates are effective in terms of preventing [malicious] traffic
> from ever showing up, or filtering it to a reasonable rate."
