  • anti-replay protection
  • confidentiality
  • authentication
  • data integrity

Explanation: Anti-replay protection is the ability to detect and reject replayed packets. By comparing sequence numbers, it helps prevent spoofing by verifying that each packet is unique and not duplicated. Authentication verifies the identity of the source of the data that is sent. Confidentiality is the process of taking all the data that one computer is sending to another and encoding it into a form that only the other computer will be able to decode. Data integrity is achieved by IPsec because the receiver can verify that the data was transmitted through the Internet without being changed or altered in any way.
