This module will present an overview of the authentication, authorization,
and accounting (AAA) architecture and show its importance of identity services
in network security. AAA security is one of the primary components of the
overall network security policy of an organization. AAA is essential to
providing secure remote access to the network and remote management of network
devices. After a brief discussion of AAA, several authentication methods will
be discussed.
Cisco Identity Based Networking Services (IBNS) and Network
Admission Control (NAC) are also introduced in this module. IBNS is an
integrated solution combining several Cisco products that offer authentication,
access control, and user policies to secure network connectivity and resources.
NAC is an industry initiative, sponsored by Cisco Systems, that uses the
network infrastructure to enforce security policy compliance on all devices
seeking to access network computing resources, thereby limiting damage from
viruses and worms.
