  • Abstract: The purpose of this white paper is to present discussion and findings that conclude that Cisco MPLS-based VPNs are as secure as their layer 2 counterparts such as Frame- Relay and ATM. This document details a series of tests were carried out on a Cisco router test bed validating that MPLS based VPNs (MPLS-VPN) provide the same security as Frame-Relay or ATM. ATM and Frame-Relay have a reputation in the industry as being secure foundations for enterprise connectivity. Essential items that make ATM and Frame-Relay a secure network were considered and tested on an MPLS-VPN.

  • Insider attacks pose an often neglected threat scenario when devising security mechanisms for emerging wireless technologies. For example, traffic safety applications in vehicular networks aim to prevent fatal collisions and preemptively warn drivers of hazards along their path, thus preserving numerous lives. Unmitigated attacks upon these networks stand to severely jeopardize their adoption and limit the scope of their deployment.

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.
