Appendix A: Glossary

E

EAP Extensible Authentication Protocol. A protocol that allows PPP to use authen- tication protocols that are not part of the PPP suite. For more information, see RFC 3748 at http://www.ietf.org/rfc/rfc3748.txt. See also CHAP and PAP

EAPOL EAP over LAN. An encapsulation method for transmitting EAP over local area networks that is used by 802.1X.

EAP-GTCEAP with Generic Token Card. An implementation of EAP that uses a token card for authentication. For more information, see RFC 3748 at http:// tools.ietf.org/html/rfc3748.

EAP-TLSEAP with TLS. An implementation of EAP that provides mutual certificate authentication between client and server. For more information, see RFC 2716 at http://tools.ietf.org/html/rfc2716.

EAP-TTLSEAP with Tunneled TLS. An implementation of EAP in which the server authenticates with a certificate, but the client authenticates (usually with a password) using a different protocol sent over a secure tunnel. For more information, see the Internet Draft at http://www3.ietf.org/proceedings/02jul/

eDirectory A hierarchical, LDAP-based directory service from Novell that can interoperate with NetWare, AIX, HP-UX, Solaris, Windows, and Linux-based network serv- ers.

EI See endpoint integrity.

endpoint A device that connects to a network, such as a desktop computer, a laptop computer, or a server.

endpoint integrity The functionality that examines all endpoints that attempt to attach to the network and prohibits unsafe or non-compliant endpoints from gaining access. Endpoint integrity ensures that an endpoint that attaches to the edge of the network is clean and meets configured criteria (for example, antivirus program present and running with current signatures) before allowing it to access network resources.

end-user screen NAC 800 message windows that appear on the end-user’s monitor; they show information such as the endpoint’s test status and remediation steps, permitting the user to download an agent, cancel testing, and get more information about why a test failed.
