What is Phase 1 in VPN?

Phase 1 in VPN refers to the initial stage of establishing a secure communication channel between two or more remote networks. This phase mainly deals with setting up the basic parameters for the VPN connection, such as the encryption algorithms, hashing methods, authentication protocols, and key exchange mechanisms. The objective of Phase 1 is to establish the trust between the two networks and to negotiate the shared security parameters that will be used for subsequent communication and data transfer. Once the Phase 1 negotiation is completed successfully, the VPN connection proceeds to the Phase 2, which involves further authentication and encryption of data traffic.
