It is a suite of encryption protocols that is commonly used by VPNs to securely transport data between two points. IPsec itself is made up of three primary elements; Encapsulating Security Payload (ESP), Authentication Header (AH), and Security Associations (SAs). WebLike ssh, Ipsec uses symmetric encryption for data confidentality and then exchange the key. Authentication is different in ssh and ipsec. Both ssh and ipsec uses hash for data integrity verification. SNMPv3.
