A network switch automatically detects undesired network traffic and mirrors the undesired traffic to a security management device. The security management device determines the source of the undesired traffic and redirects traffic from the source to itself. The security management device also automatically sends a policy to a switch to block traffic from the source.

Network threat detection and mitigation

A network switch automatically detects Voice over Internet Protocol (VoIP) traffic and mirrors the VoIP traffic to a security management device. The security management device measures a rate of call setup packets in the VoIP traffic. The security management device detects an attack based on a comparison of the measured rate of call setup packets to a threshold rate. Detected attacks are mitigated.

VoIP security

A network switch detects at least two simultaneous connections on a single network port. The simultaneous connections use different protocols despite using the same port. The network switch mirrors network traffic associated with the simultaneous connections to a security management device on the network. The security management device then determines a source or destination of the network traffic.
