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 ...
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 ...
IEEE 802.1. IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association. It is concerned with: [1] 802 LAN / MAN architecture. internetworking among 802 LANs, MANs and wide area networks. 802 Link Security. 802 overall network management.
t. e. In IEEE 802 LAN/MAN standards, the medium access control (MAC), also called media access control, is the layer that controls the hardware responsible for interaction with the wired (electrical or optical) or wireless transmission medium. The MAC sublayer and the logical link control (LLC) sublayer together make up the data link layer.
Token Ring is a physical and data link layer computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network administrator.
NIST RBAC model. The NIST RBAC model is a standardized definition of role-based access control. Although originally developed by the National Institute of Standards and Technology, the standard was adopted and is copyrighted and distributed as INCITS 359-2004 by the International Committee for Information Technology Standards (INCITS).
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 ...
