Abstract

This bulletin summarizes NIST SP 800-77, Guide to IPsec VPNs, which was issued by NIST to help network architects, network administrators, security staff, technical support staff, and computer security program managers who are responsible for the technical aspects of preparing, operating and securing their organization¿s networks. The bulletin provides information about implementing security services based on Internet Protocol Security (IPsec), a framework of open standards for ensuring private communications over public networks. The bulletin advises organizations how to use IPsec to achieve security controls in the layered protocols of network communications, and to create a virtual private network (VPN) to protect communications carried over public networks, such as the Internet. Topics covered include the need for network layer security services, the services that are available at the network layer, and how IPsec can be implemented to provide these services.
