Extreme Networks has launched the latest version of its modular operating system ExtremeXOS.

The upgrade features enhancements for securing networks using Network Access Control (NAC) technologies that Extreme Networks claimed removed an NAC exploit that could leave systems at risk of attack.

The vendor said the use of Dynamic Host Configuration Protocol (DHCP) servers when deploying NAC to protect a network perimeter often left companies vulnerable as users that were denied access could simply configure a static internet protocol (IP) address to gain entry to the network and get out of quarantine.

Extreme Networks said the latest version of XOS removed this exploit by requiring a switch to make all endpoints only allow devices with valid DHCP assigned IP addresses into the network.

“With this software release, customers can choose their best security approach regardless of the NAC enforcement mode,” said Chris Moore, Extreme Networks regional director for MEA.
