US communications networking equipment manufacturer 30 ComNet has added the Port Guardian cyber-security features to its latest generation of self-managed switches which can physically disconnect a port if unauthorised access is detected.

Port Guardian covers situations where network access is attempted by disconnecting an IP addressable device connected to the network. When Port Guardian senses intrusion, a notification is sent and the effected port is physically locked out, preventing access and thwarting access through ‘spoofing’.

The network administrator can reopen the port when the threat is eliminated.

This new feature is being added to ComNet’s latest generation of SMS products and will also be available on the new ComNet managed switch line.
