Network admission control systems allow noncompliant devices to be denied access, placed in a quarantined area, or given restricted access to computing resources, thus keeping insecure nodes from infecting the network. The key component of the Cisco Network Admission Control program is the Cisco Trust Agent, which resides on an endpoint system ...
Description. Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before ...
Cisco NAC Appliance, formerly Cisco Clean Access (CCA), was a network admission control (NAC) system developed by Cisco Systems designed to produce a secure and clean computer network environment. Originally developed by Perfigo and marketed under the name of Perfigo SmartEnforcer, this network admission control device analyzes systems ...
TACACS. Terminal Access Controller Access-Control System ( TACACS, / ˈtækæks /) refers to a family of related protocols handling remote authentication and related services for network access control through a centralized server. The original TACACS protocol, which dates back to 1984, was used for communicating with an authentication server ...
IEEE 802.1X is an IEEE Standard for port-based network access control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN . The standard directly addresses an attack technique called Hardware Addition [1] where an attacker posing as a guest ...
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists who had been instrumental in connecting computers at Stanford. They pioneered the concept of a local area network (LAN) being used to connect distant computers over a multiprotocol router system.
