Senetas Corporation (ASX:SEN) has announced new functionality for its high-speed network encryption platform, claiming enhanced security for virtual local area networks (VLANs).
In a statement to the ASX, the company said VLANs, while typically used to separate networks into different user groups for simplified management and better usability, had no real security except traffic separation.
“VLAN separation alone cannot provide even a minimum level of security… the technology has not been designed with security in mind,” Senetas chief technologist, Julian Fay, said in the statement. “To reduce a network’s susceptibility to data theft or network subversion encryption should be deployed.”
According to the company, Senetas CN1000/3000 encryptors can protect up to 512 virtual LANs at one gigabit per second (Gbps), and up to 64 VLANs at 10Gbps using an encryption policy based on VLAN tags rather than MAC addresses.
“While VLANs do segregate visibility of different data streams on a single piece of wire or fibre, they don’t secure the information, therefore VLANs do remain vulnerable and should be encrypted as they pass in and out of the organisation’s firewalls,” Fay said.
The latest VLAN release includes an automatic establishment of encrypted VLAN connections, a highly scalable capability across multipoint VLAN topologies, management for network outages and can host an ‘unlimited’ number of devices connected to each secure connection.
As reported by Computerworld Australia, earlier this year Senetas was officially “axed” by Telstra (ASX:TLS), despite supplying application development and production, maintenance and support services to the telco for almost a decade.
