Quizplus · Accepted Answer

The Authentication Header (AH) protocol provides authentication and integrity services for IP packets, but it does not provide confidentiality because it does not support data encryption. AH adds a header to the IP packet that contains authentication information, such as a message authentication code (MAC), which ensures that the packet has not been tampered with during transmission. Internet Key Exchange (IKE) and Encapsulating Security Payload (ESP) are other IPsec protocols that provide confidentiality along with authentication and integrity services. BitLocker is a Microsoft encryption tool designed primarily for disk encryption on Windows systems and is not related to IPsec.
