This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS Plus ( TACACS+ ) is a protocol developed by Cisco and released as an open standard beginning in 1993.

They define how information sent/received through the connection are encoded (as in Content-Encoding), the session verification and identification of the client (as in browser cookies, IP address, user-agent) or their anonymity thereof (VPN or proxy masking, user-agent spoofing), how the server should handle data (as in Do-Not-Track or Global ...
A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
Unix-like operating systems identify a user by a value called a user identifier, often abbreviated to user ID or UID. The UID, along with the group identifier (GID) and other access control criteria, is used to determine which system resources a user can access. The password file maps textual user names to UIDs.
When a user logs on, the firewall associates that login with the user's IP address. Define User Groups — Within the firewall's management interface, define user groups based on the directory service. For example, create groups such as "Students". Create Firewall Rule: Source: User ID (e.g., Students) Destination: list of IP addresses
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
