Connection-Rate Filtering Based On Virus-Throttling Technology
While not specifically a tool for controlling network access, this feature does help to protect the
network from attack and is recommended for use on the network edge. It is primarily focused on the
class of worm-like malicious code that tries to replicate itself by taking advantage of weaknesses in
network applications behind unsecured ports. In this case, the malicious code tries to create a large
number of outbound IP connections on a routed interface in a short time. Connection-Rate filtering
detects hosts that are generating routed traffic that exhibits this behavior, and causes the switch to
generate warning messages and (optionally) to either throttle routed traffic from the offending hosts
or drop all traffic from the offending hosts.
Refer to the chapter titled “Virus Throttling” in the Access Security Guide for your switch model.
