Implementation Considerations for a Virtual Private Network (VPN) to Enable Broadband Secure Remote Access to the Naval Postgraduate School Intranet

摘要

As broadband connections to the home become more prevalent, through Digital Subscriber Lines (DSL) and cable modems, students and faculty will desire to access the NPS Internet via these new means instead of their 56K modems. The introduction of these new technologies will require NPS to re- evaluate how to allow remote access to their internal resources in a secure way, while still allowing for the use of broadband technologies. This thesis will examine the alternative methods for implementing VPNs, from simple use of Point to Point Protocols (PPP) to high end specialized internet appliances and gateways. Pros and cons of each will be discussed. A mock-up of the schools network will be created to test each of the discussed methods. Final recommendations will be made for a model that can be used by the NPS to implement a VPN. Also discussed will be how that model may be altered to fit other commands throughout the US Navy who desire similar secure remote access to their internal network resources.
