Security Issues


The Network Security focus group resolved and rationalized security standards for next generation interfaces, 802.11 wireless LANs and IP networks.

This focus group utilized the findings from the ATIS Security Summit, "Security of Service Provider Infrastructure in an Era of Convergence," to define a coordinated standards development program for network security.

In March 2006, the Security Focus Group transitioned to the Inter-committee Security Review Group (ISRG). This group is represented by former Security FG members as well as leaders of ATIS committees. The ISRG continues to track existing security issues and also identifies new security issues that need to be addressed by the industry
