ComNet enhances cybersecurity for port connections

ComNet Europe, part of the US manufacturer or transmission and communication networking equipment ComNet Communication Networks, has introduced a new cybersecurity feature in its latest generation of self-managed switches.

Known as Port Guardian, the feature has the capability to physically disconnect a port if unauthorised access is detected.

Port Guardian can provide a line of defence in situations where network access is attempted by disconnecting an IP-addressable device on the edge in order to connect to the network.

Port Guardian senses the disconnection activity and in response an SNMP notification is sent to the head end. The affected port is physically locked out, preventing access.

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

The Port Guardian feature also rejects access through an activity known as ‘spoofing’ by disconnecting the port when an interruption is sensed.

Port Guardian is being added to the newest generation of ComNet SMS products, including the CNGE2+2SMS and CNGE4+2SMS. The feature will also be available on the new ComNet USA-made line of managed switches.

According to Steve Clarke, ComNet Europe managing director: “Cybersecurity is not something confined to just a security IP network. Any network can be infiltrated. By introducing this valuable feature on these cutting-edge products, we can provide another unmatched advantage to our partners.”
