Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:
According to the Forescout Blog on Post-Connect Access Controls and the Comply-to-Connect framework documentation, a Post-Connect Methodology is best defined as treating endpoints as "Innocent until proven guilty".
Definition of Post-Connect Methodology:
According to the official documentation:
"Post-connect" is described as treating endpoints as innocent until they are proven guilty. They can connect to the network, during and after which they are assessed for acceptance criteria."
How Post-Connect Works:
According to the Post-Connect Access Controls blog:
Initial Connection - Endpoints are allowed to connect to the network immediately (innocent)
Assessment During/After Connection - After connecting, endpoints are assessed for acceptance criteria
Compliance Checking - Endpoints are checked for:
Corporate asset status (must be company-owned)
Security compliance (antivirus, patches, encryption, etc.)
Remediation or Quarantine - Based on assessment results:
Compliant endpoints: Full access
Non-compliant endpoints: Placed in quarantine for remediation
Post-Connect vs. Pre-Connect:
According to the Comply-to-Connect documentation:
Pre-Connect - "Guilty until proven innocent" - Endpoint must prove compliance BEFORE getting network access
Post-Connect - "Innocent until proven guilty" - Endpoint connects first, then compliance is assessed
Benefits of Post-Connect Methodology:
According to the documentation:
"The greatest benefit to the post-connect approach is a positive user experience. Unless a system is out of compliance and ends up in a quarantine, your company's users have no idea access controls are even taking place on the network."
Acceptance Criteria in Post-Connect:
According to the framework:
Corporate Asset Verification - Determines if the endpoint belongs to the organization
Compliance Assessment - Checks for:
If an endpoint fails these criteria, it's placed in quarantine (controlled network access) rather than being completely blocked.
Why Other Options Are Incorrect:
A. 802.1X is a flavor of Post-Connect - 802.1X is a pre-connect access control method (requires authentication before network access)
B. Guilty until proven innocent - This describes pre-connect methodology, not post-connect
D. Used subsequent to pre-connect - While post-connect can follow pre-connect, this doesn't define what post-connect is
E. Assessed for critical compliance before IP address is assigned - This describes pre-connect methodology
