Description: Secure Remote Access with Layer 2 tunneling Protocol (L2TP) extends the security characteristics of Internet Protocol Security (IPsec) to remote access users, as they dial-in through the Internet. Layer 2 Tunneling Protocol (L2TP) is a virtual extension of Point to Point Protocol (PPP) across Internet Protocol (IP) network infrastructure. L2TP makes possible for an L2TP access concentrator (LAC) to be near remote clients, while allowing PPP L2TP Network Server (LNS) to be located in enterprise premises. L2TP allows an enterprise to retain control of Remote Authentication Dial-In User Service (RADIUS) data base, which is used to control Authentication, Authorization and Accountability (AAA) of dial-in users. The objective of this document is to extend security characteristics of IPsec to remote access users, as they dial-in through the Internet.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
