What is Phase 2 in VPN?

Phase 2 in VPN is the stage of securing communication between two remote sites or devices after the completion of the initial phase, which deals with the establishment of the security associations. In Phase 2, the actual exchange of data takes place between the two endpoints and the VPN tunnel is fully established. This phase involves negotiating the parameters for the encryption and authentication methods to be used to secure the data, as well as the lifetime of the security associations. The goal of Phase 2 is to ensure that the communications between the two endpoints remain secure and private, and that no unauthorized access or interception occurs.
