Host Integrity Check (HIC)
Host Integrity Check (HIC) is a mechanism for verifying the compliance of an end user device when it
connects to the switch. Configurable HIC policies are used to specify, evaluate, and enforce network
access requirements for the host. For example, is the host running a required version of a specific
operating system or anti-virus software up to date.
The Access Guardian implementation of HIC is an integrated solution consisting of switch-based
functionality, the InfoExpress compliance agent (desktop or Web-based) for the host device, and
interaction with the InfoExpress CyberGatekeeper server and Policy Manager. The switch-based
functionality is provided through the configuration of a User Network Profile (UNP), which contains a
configurable HIC attribute.
NOTE: Minmum ASIC versions are required for HIC support as noted below. Use the ‘show ni’
command documented in the Supported Hardware/Software Combinations section to verify the
ASIC version.

User Network Profile (UNP)
A User Network Profile (UNP) defines network access controls for one or more user devices. Each
device that is assigned to a specific profile is granted network access based on the profile criteria,
instead of on an individual MAC address, IP address, or port. Assigning users to a profile provides
greater flexibility and scalability across the network. Administrators can use profiles to group users
according to function. All users assigned to the same UNP become members of that profile group. The
