VE3OGG writes "Cisco, the networking Goliath, has decided to release the source code of its NAC (network admission control) client, Cisco Trust Agent (CTA) to the open source community within 'a few months.' This comes hot on the heels of Cisco announcing its plans to redevelop a new breed of network security infrastructure. 'CTA will be something that's open source. That's just logically where it should end up,' Gleichauf told InfoWorld. 'We don't want to be in the CTA business, so we're going to just open it up.'"
