Physical Layer Security Issues

Conventional wired networks are subject to being tapped by a variety of means, whether copper or fiber connections are used. In addition, methods of network snooping exist that make such eavesdropping minimally invasive, but no less significant. Wireless networking has additional characteristics that also decrease physical network security. As new technologies emerge, the potential for loss of company information through lax physical security must be carefully evaluated and steps taken to mitigate the risk. In addition to automated security measures, such as intrusion detection and direct wiring monitoring, careful network management procedures can enhance physical security. Proper network design is critical to maintaining the desired level of security. In addition to the measures used on wired networks, wireless networks should be protected with encryption.
