Check: FORE-NC-000070
Forescout Network Access Control STIG:
FORE-NC-000070
(in versions v1 r2 through v1 r1)
Title
Forescout appliance must not be configured to implement a DHCP layer 3 method for separation or device authorization. (Cat I impact)
Discussion
An internal rogue device can still bypass the authentication process, regardless of the policy flow. Configuring the NAC to process all device authentication will ensure that any rogue device, internal or external, will be authenticated prior to network access.
Check Content
Check Forescout policy and ensure it is configured to prohibit the use of DHCP to separate authenticated and non-authenticated network access requests. If the NAC does not prohibit the use of DHCP to separate authenticated and non-authenticated network access requests, this is a finding.
Fix Text
Log on to the Forescout UI. 1. Locate the Authentication & Authorization policy. 2. Ensure all traffic passing through the NAC is properly labeled and that all authenticated and non-authenticated traffic goes through the NAC.
