An IPsec packet is processed according to a set of security rules called a security association (SA). The SA specifies the protocols to be followed for key exchange systems, authentication and encryption algorithms, and secure communications between two parties. Multiple SAs are used in a single secure tunnel.

Communication between hosts can occur while adhering to security parameters specified by an IPsec security association (SA). For these hosts to securely communicate, two SAs are typically needed. Data is protected in one direction by a single SA. Either a single host or a group (multicast) address is protected.
