ComNet Europe’s latest generation of self-managed switches now have the capability to physically disconnect a port if unauthorised access is detected.

According to US-based ComNet, an organisation’s security network, with its accessible outside connection, presents an “easy way” to bring down the network. It says cyber security is therefore not something confined to just a security IP network, as any network can be infiltrated.

The new ComNet Port Guardian will disconnect an IP addressable device on the edge of the network when access from an unknown source is attempted. An SNMP notification is then sent to the head end and the affected port is physically locked out, preventing entry. 

ComNet says the network administrator can reopen the port when the threat is eliminated. It adds that the feature also thwarts access through spoofing by disconnecting the port as soon as an interruption is sensed. 

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