The HYCU virtual appliance must be configured to use DOD-approved online certificate status protocol (OCSP) responders or certificate revocation lists (CRLs) to validate certificates used for PKI-based authentication.

Description
Once issued by a DOD certificate authority (CA), public key infrastructure (PKI) certificates are typically valid for three years or shorter within the DOD. However, there are many reasons a certificate may become invalid before the prescribed expiration date. For example, an employee may leave or be terminated and still possess the smartcard on which the PKI certificates were stored. Another example is that a smartcard containing PKI certificates may become lost or stolen. A more serious issue could be that the CA or server which issued the PKI certificates has become compromised, thereby jeopardizing every certificate keypair that was issued by the CA. These examples of revocation use cases and many more can be researched further using internet cybersecurity resources. PKI user certificates presented as part of the identification and authentication criteria (e.g., DOD PKI as multifactor authentication [MFA]) must be checked for validity by network devices. For example, valid PKI certificates are digitally signed by a trusted DOD CA. Additionally, valid PKI certificates are not expired, and valid certificates have not been revoked by a DOD CA. Network devices can verify the validity of PKI certificates by checking with an authoritative CA. One method of checking the status of PKI certificates is to query databases referred to as certificate revocation lists (CRL). These are lists which are published, updated, and maintained by authoritative DOD CAs. For example, once certificates are expired or revoked, issuing CAs place the certificates on a CRL. Organizations can download these lists periodically (i.e., daily or weekly) and store them locally on the devices themselves or even onto another nearby local enclave resource. Storing them locally ensures revocation status can be checked even if internet connectivity is severed at the enclave's point of presence (PoP). However, CRLs can be rather large in storage size and further, the use of CRLs can be rather taxing on some computing resources. Another method of validating certificate status is to use the OCSP. Using OCSP, a requestor (i.e., the network device which the user is trying to authenticate to) sends a request to an authoritative CA challenging the validity of a certificate that has been presented for identification and authentication. The CA receives the request and sends a digitally signed response indicating the status of the user's certificate as valid, revoked, or unknown. Network devices should only allow access for responses that indicate the certificates presented by the user were considered valid by an approved DOD CA. OCSP is the preferred method because it is fast, provides the most current status, and is lightweight. Satisfies: SRG-APP-000175-NDM-000262, SRG-APP-000177-NDM-000263, SRG-APP-000080-NDM-000220

Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-268235r1038742_chk)

Log in to the HYCU console and execute the following command: sudo cat /opt/grizzly/config.properties | grep cert.path.revocation.checking.enabled=true If the variable is not set to true, this is a finding.

Fix Text (F-72159r1038404_fix)

OCSP revocation applies to all SSL communication done from HYCU Java application, including SMTP in SSL mode, LDAPS, and any HTTPS interaction (platform API servers, cloud targets, webhooks, etc.). To enable OCSP revocation, log in to the HYCU console and edit the config file by executing the following command: sudo vi /opt/grizzly/config.properties and add the following line: cert.path.revocation.checking.enabled=true
