Discussion

For user certificates, each organization obtains certificates from an approved shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority at medium assurance or higher, this Certification Authority will suffice.

Determine if Forescout obtains public key certificates from an appropriate certificate policy through an approved service provider.

To review the Web server certificate presented for captive portal/authentication:

1. Log into the Forescout management console.
2. Go to Options >> Certificates >> System Certificates.
3. Locate the certificates where the "Used For" column shows "Web Portal".
4. Ensure all enabled certificates are issued by a trusted CA and are not self-signed.

If the ForeScout does not obtain its public key certificates from an appropriate certificate policy through an approved service provider, this is a finding.
