1 CHAPTER 32 Security In the Internet Solutions to Odd-Numbered Review Questions and Exercises Review Questions 1. IPSec needs a set of security parameters before it can be operative. In IPSec, the establishment of the security parameters is done via a mechanism called security association (SA) . 3. The two protocols defined by IPSec for exchanging datagrams are Authentication Header (AH) and Encapsulating Security Payload (ESP). 5. The Encapsulating Security Payload (ESP) protocol adds an ESP header , ESP trailer , and the digest . The ESP header contains the security parameter index and the sequence number fields. The ESP trailer contains the padding, the padding length, and the next header fields. Note that the digest is a field separate from the header or trailer. 7. The two dominant protocols for providing security at the transport layer are the Secure Sockets Layer (SSL) Protocol and the Transport Layer Security (TLS) Protocol. The latter is actually an IETF version of the former.
