Exam 200-301 topic 1 question 983 discussion

IPsec (Internet Protocol Security) is a suite of protocols used for securing internet protocol (IP) communications. The two protocols within the IPsec suite are: Authentication Header (AH): AH provides data authentication and integrity protection for IP packets, but does not provide encryption. AH calculates a hash value over the IP packet and some additional data, and places the result in a new header that is added to the packet. Encapsulating Security Payload (ESP): ESP provides both encryption and data authentication for IP packets. ESP encrypts the original IP packet and places it inside a new packet, along with a new ESP header that provides data authentication and integrity protection. Both AH and ESP protocols can be used alone or in combination to provide secure communication between two network devices. AH and ESP are often used in conjunction with the Internet Key Exchange (IKE) protocol, which is used to negotiate and establish security associations (SAs) between devices.
