When editing a Host Integrity Policy in the Symantec Network Access Control (SNAC) product, what functionality is available for creating Custom Requirements?
The Host Integrity functionality in the Symantec Network Access Control (SNAC) product is used to verify the integrity of endpoint machines before assigning a policy or allowing entrance to the network. Built-in checks exist to verify the status of Antivirus, Antispyware, and Firewall software, and Patch and Service pack level - more complex checks can be created using the Custom Requirement option.
The following list of checks or conditions are available when creating a Custom Requirement script in the Host Integrity Policy editor.
Antivirus: Antivirus is installed
Antivirus: Antivirus is running
Antivirus: Antivirus signature file is up-to-date
Antispyware: Antispyware is installed
Antispyware: Antispyware is running

For the list of Antivirus, Antispyware and Firewall products that can be verified by the built-in rules, please see KB TECH162768.
In addition to the list of conditions available above, the following list of functions can also be added to a Custom Requirement script.
File: Download a file
Registry: Set registry value
Registry: Increment registry DWORD value
Utility: Log message
Utility: Run a program

The Custom Requirement script editor also provides regular logic such as IF/THEN/ELSE and AND/OR to use when constructing your Host Integrity script, and right-clicking on a configured condition in the Host Integrity script editor gives a "Toggle NOT" option, to reverse the logic of the check.
