Overview
NAC 800 protects the network by ensuring that endpoints are free from threats
and in compliance with the organization's IT security standards. NAC 800
systematically tests endpoints—with or without the use of a client or agent—
for compliance with organizational security policies, quarantining non-com-
pliant machines before they damage the network.
NAC 800 ensures that the applications and services running on endpoints
(such as LAN, RAS, VPN, and WiFi endpoints) are up-to-date and free of
worms, viruses, trojans, P2P and other potentially damaging software. It
dramatically reduces the cost and effort of securing your network's weakest
links—the endpoints your IT group might not adequately control.
There are advantages and disadvantages inherent with each of the test method
technologies. Having a choice of testing solutions enables you to maximize
the advantages and minimize the disadvantages.
Agentless testing uses an existing Windows service (RPC). ActiveX testing
uses an ActiveX control. ProCurve agent testing installs an agent (ProCurve
NAC EI Agent) and runs as a new Windows service.
The trade-offs in the test methods are described in the following table:
network access without any end-user
interaction for on your Windows
endpoints
domains.
less expensive than agent-based solutions.
Cons
• Requires RPC Service to be available to the
NAC 800 server (ports 139 or 445).
• Requires file and print sharing to be enabled.
• Not supported by legacy Windows™
operating systems and non-Windows
operating systems.
• If the endpoint is not on a domain, the user
must specify local credentials. A user often
does not know what credentials to enter.
