: Last-Mile Disruptions"> Like AT&T, Sprint found that its own facilities were fine, but that last-mile access was disrupted. It has since incorporated last-mile connections into its disaster recovery and business continuity planning. Genuity Inc. found its security mechanisms needed a boost post-Sept. 11. The Woburn, Mass., company realized its own internal network and its control network, used to manage its commercial network, lacked intrusion detection.
The control network, dubbed the Operations, Administration Maintenance and Provisioning (OAMP) Network, had some level of protection, but not enough. "We had firewalled it off, but we never went as far as measuring the network at access points to see if someones attempting to get in," said Chris Yetman, vice president of operations architecture, design and support in Woburn, Mass. "Now if someones trying a brute-force attack by going through a dictionary, it will raise an alarm in the operations center while it is going on, allowing us to respond."
An internal audit committee, which determined the need for the intrusion detection on the OAMP network, also determined that Genuitys contingency plans didnt go far enough. While the plans initially focused on major facilities, such as the Network Operations Center, they were extended after Sept. 11 to include other buildings. "Weve got written plans and electronically set up redundant systems so we can monitor from other locations. But the big difference now is that we exercise those plans once a quarter to make sure we can still cut over the NOCs and make sure we can monitor from a secondary site. Its a significantly higher level of diligence in terms of disaster recovery," said Yetman. Special Report: Rebuilding for Tomorrow
