Quote: "The threat that contemporary electronic intruders pose to the PSN [Public Switched Network] is rapidly changing and is significant. As a result of their increasing knowledge and sophistication, electronic intruders amy have a significant impact upon national security and emergency preparedness (NS/EP) telecommunications, because more than 90 percent of U.S. Government telecommunications services are provided by commercial carriers. ...technological changes and market forces in the domestic telecommunications industry are fueling a trend toward increasing automation and downsizing of staff. Consequently, there are now greater numbers of current and former telecommunications employees who may be disgruntled than at any time in recent years. These individuals should be viewed as a potential threat to NS/EP telecommunications." - The Electronic Intrusion Threat to National Security and Emergency Preparedness Telecommunications, published by National Communications System of Arlington, VA and leaked to us by a disgruntled employee.
