Cisco has bolstered its Internetwork Operating System (IOS) with new security features. The IOS software, which controls Cisco's networking hardware, now supports L2TP (Layer 2 Tunnelling Protocol) for virtual private networking. L2TP is the amalgamation of Cisco's own L2F (Layer 2 Forwarding) protocol and Microsoft's PPTP (Point-to-Point Tunnelling Protocol). L2TP, which is being ratified as an industry standard, has already lost some of its momentum to the IPSec (IP Security) protocol, which is expected to become the predominant virtual private network (VPN) security technology once it is approved by the Internet Engineering Task Force.
