RADIUS Security
RADIUS is an IETF- developed protocol that defines a communication
standard between a Network Access Server (NAS) and a host-based
communication server. RADIUS modes are as follows:
• RADIUS Authentication includes authentication of the
dial-up user to the RADIUS server, and authentication of the
RADIUS server to the NAS. RADIUS supports authentication
modes PAP and CHAP (Challenge Handshake Authentication
Protocol).
• RADIUS Accounting, another IETF-developed protocol, defines
a communication standard between an NAS and a host-based
accounting server. It records duration of service, packet
throughput, and raw throughput.
• Although RADIUS Authorization is not supported in this
release, Authorization is addressed by the Access Control
Protocol (ACP). Authorization of the acp_userinfo,
acp_restrict, and acp_dialup files applies to users that are
authenticated through RADIUS.
