The encapsulating security protocol provides secrecy for the contents of network communications as well as system-to-system authentication and data integrity verification.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

The encapsulating security payload (ESP) protocol is a standard protocol that provides secrecy for the contents (data) transmitted via network communications, as well as system-to-system authentication and data integrity verification so as to prevent unauthorized access.

Basically, the encapsulating security payload (ESP) protocol is a transport layer protocol that provides data confidentiality, integrity and authentication in IPv6 and IPv4 protocols.
