Explain all services that provided by ESP of IPSEC.

Answer 1

Explain all services that provided by ESP of IPSEC.

Ans) The Answer for your question is given below clearly

Access control, to prevent an unauthorized access to the resource. Both AH and ESP are vehicles for access control, based on the distribution of cryptographic keys and the management of traffic flows relative to these security protocols.

b) Connectionless Integration. To give an assurance that the traffic received has not been modified in any way.

c) Data Origin authentication. Particularly source authentication so that when a destination host receives an IP datagram, with a particular IP source address, it is possible to be sure that the IP datagram was indeed generated by the host with the source IP address. This prevents spoofed IP addresses.

d) Rejection or replayed packets. (Sequence number): to guarantee that each packet exchanged between two parties is different.

e) Confidentiality (encryption): to ensure that internet trafficked is not examined by non-authorized parties. This requires all IP datagrams to have their data field, TCP, UDP, ICMP, or any other datagram data field segment, encrypted.

f) Limited traffic flow confidentiality (padding)
