What is a characteristic of the IP authentication header?
- the assurance that the original data packet has not been modified during transport
- the provision for data confidentiality, integrity, and authentication
- the use of protocol number 50 located in the IP header
- the encryption of data to ensure it is viewable by only authorized users
Explanation: IPsec uses two protocols to provide data integrity and confidentiality, the IP Authentication Header (AH) and the Encapsulating Security Payload (ESP). AH, which is IP protocol 51, provides integrity and authentication but does not provide encryption. AH can ensure that the original data packet has not been modified during transport but it does not encrypt data to ensure it is viewable only by authorized users. ESP encrypts the data in the packet for data confidentiality.
