Tunneling of classified traffic across an unclassified IP transport network must employ cryptographic algorithms in accordance with CNSS Policy No. 15.

Description
When transporting classified data over an unclassified IP network, it is imperative that traffic from the classified enclave or community of interest is encrypted prior reaching the point of presence or service delivery node of the unclassified network. Confidentiality and integrity of the classified traffic must be preserved by employing cryptographic algorithms in accordance with CNSS Policy No. 15 which requires the appropriate Suite B cryptographic algorithms listed in ANNEX B or a commensurate suite of NSA-approved cryptographic algorithms.

Who does this work

8 NICE work roles and 7 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-251351r916232_chk)

Review the configuration of the IPsec VPN gateway and verify that the tunnel provisioned for transporting classified traffic across an unclassified IP transport network is using cryptographic algorithms in accordance with CNSS Policy No. 15. If cryptographic algorithms used for tunneling classified traffic across an unclassified network are not in accordance with CNSS Policy No. 15, this is a finding.

Fix Text (F-54739r806007_fix)

Configure the tunnel used for transporting classified traffic across an unclassified IP transport network to negotiate with the remote end point to employ cryptographic algorithms in accordance with CNSS Policy No. 15.
