802.1X-2001 defines two logical port entities for an authenticated port—the "controlled port" and the "uncontrolled port". The controlled port is manipulated by the 802.1X PAE (Port Access Entity) to allow (in the authorized state) or prevent (in the unauthorized state) network traffic ingress and egress to/from the controlled port.
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association. ... Media Access Control (MAC) Key Security Merged into 802.1X-2010
A basic form of NAC is the 802.1X standard. Network access control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do.
A NAP enforcement point is a computer or device that can evaluate a NAP client's health and optionally restrict network communications. NAP enforcement points can be IEEE 802.1X-capable switches or VPN servers, DHCP servers, or Health Registration Authorities (HRAs) that run Windows Server 2008 or later.
The IEEE 802.1X standard [1] uses the term "supplicant" to refer to either hardware or software. In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication succeeds, the authenticator typically ...
The encapsulation of EAP over IEEE 802 is defined in IEEE 802.1X and known as "EAP over LANs" or EAPOL. [ 32 ] [ 33 ] [ 34 ] EAPOL was originally designed for IEEE 802.3 Ethernet in 802.1X-2001, but was clarified to suit other IEEE 802 LAN technologies such as IEEE 802.11 wireless and Fiber Distributed Data Interface (ANSI X3T9.5/X3T12, adopted ...
Key management and the establishment of secure associations is outside the scope of 802.1AE, but is specified by 802.1X-2010.. The 802.1AE standard specifies the implementation of a MAC Security Entities (SecY) that can be thought of as part of the stations attached to the same LAN, providing secure MAC service to the client.
