Sentriant AG Users' Guide, Version 5.0
A port-based authentication protocol that can dynamically vary
encryption keys, and has three components: a supplicant, an
authenticator, and an authentication server.
In Sentriant AG, NAC policies consist of individual tests that evaluate
endpoints attempting to access the network. These tests assess
operating systems, verify that key hotfixes and patches have
been installed, ensure anti-virus and other security applications
are present and up-to-date, detect the presence of worms,
trojans, and viruses, and check for potentially dangerous
applications such as file sharing, peer-to-peer (P2P), or
spyware.
A logical grouping of NAC policies.
Access control list A list or set of rules that routers (and other

software can gain entry and cause damage.
