Explanation
The Encapsulating Security Payload (ESP) provides integrity and confidentiality for network communications. ESP is a protocol that is part of the IPsec suite, which is a set of protocols and standards that provide security for Internet Protocol (IP) communications. ESP encrypts the payload of an IP packet, which is the data portion of the packet, to provide confidentiality. ESP also adds a trailer and an authentication data field to the packet, to provide integrity. ESP does not provide authorization or availability for network communications. Authorization is the process of granting or denying access to resources based on the identity or role of the requester. Availability is the property of ensuring that resources are accessible and usable by authorized parties when needed. ESP does not perform authorization or availability functions, but it may support or complement them.
