ComNet Europe has introduced a new cyber security feature in its latest generation of self-managed switches. The ComNet Port Guardian feature has the capability to physically disconnect a port if unauthorised access is detected. The value of Port Guardian comes in situations where network access is attempted by disconnecting an IP addressable device on the edge to connect to the network. When Port Guardian senses the disconnect, an SNMP notification is sent to the head end and the effected port is physically locked out, preventing access.
The network administrator can reopen the port when the threat is eliminated. This feature also thwarts access through spoofing by disconnecting the port as soon as an interruption is sensed. This feature 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 managed switch line.
Steve Clarke, ComNet Europe Managing Director, stated, ‘Unauthorised access issues or cyber security is a critical challenge facing every network manager today. A security network with its accessible outside connection is an easy way to bring down a network. Cyber security 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.’
ComNet offers an extensive line of fibre optic, copper and wireless video and data transmission equipment that is designed to meet the needs of the security market.
