14.2.1 IPSec Algorithms
The ESP (Encapsulating Security Payload) Protocol (RFC 2406) and AH (Authentication Header) protocol (RFC 2402) describe the packet formats and the default standards for packet structure (including implementation algorithms).
The Encryption Algorithm describes the use of encryption techniques such as DES (Data Encryption Standard) and Triple DES algorithms.
The Authentication Algorithms,
14.2.2 Key Management
Key management allows you to determine whether to use IKE (ISAKMP) or manual key configuration in order to set up a VPN.
14.3 Encapsulation
The two modes of operation for IPSec VPNs are Transport mode and Tunnel mode.
