System Basics: Security Services Configuration Guide
The Junos operating system (Junos OS) supports the IP Security (IPsec) associations and the Internet Key Exchange (IKE) security services features. The IPsec suite provides network layer data security with functions such as authentication of origin, data integrity, confidentiality, replay protection, and nonrepudiation of source. IKE defines mechanisms for key generation and exchange and manages security associations (SAs). An SA is a simplex connection that allows two hosts to communicate with each other securely by means of IPsec. Use the topics in this section to configure essential security services.
