Description: Securing Layer Two Tunneling Protocol (L2TP) with Internet Protocol Security (IPsec) is a standard that explains to users how L2TP may utilize IPsec to provide for tunnel authentication, privacy protection, integrity checking and replay protection. After the process is complete, the L2TP packets between the endpoints are encapsulated by IPsec. Seeing that L2TP packet itself is wrapped and hidden within the IPsec packet, there is no information about the internal private network that can be garnered from the encrypted packet.
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.
