Since the last meeting of the President's National Security Telecommunications Advisory Committee (NSTAC) in September 1998, the Network Group (NG) has directed its efforts to four activities. Two of these activities involve the NG's ongoing responsibilities: facilitating the exchange of network security research and development (R&D) information between industry and Government and overseeing the NSTAC Network Security Information Exchange (NSIE). Discussions at NSTAC XX resulted in an additional tasking that has now been completed: examining how national security and emergency preparedness (NS/EP) operations might be affected by a severe disruption of Internet service. Lastly, in conjunction with the gap analysis effort by the Office of the Manager, National Communications System (OMNCS), NG members provided their individual perspectives on the Public Network (PN) Alternative Analysis Report developed by the OMNCS. This report outlines these activities.
