The Cisco ASA must be configured to use FIPS-validated SHA-2 at 384 bits or higher for Internet Key Exchange (IKE) Phase 1.

Description
Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Although allowed by SP800-131Ar2 for some applications, SHA-1 is considered a compromised hashing standard and is being phased out of use by industry and government standards. Unless required for legacy use, DOD systems should not be configured to use SHA-2 for integrity of remote access sessions.

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-239958r916134_chk)

Review the ASA configuration to verify that SHA-2 at 384 bits or higher is specified for IKE Phase 1 as shown in the example below. crypto ikev2 policy 1 … integrity sha384 If the ASA is not configured to use SHA-2 at 384 bits or higher for IKE Phase 1, this is a finding.

Fix Text (F-43150r916133_fix)

Configure the ASA to use FIPS-validated SHA-2 at 384 bits or higher for IKE Phase 1 as shown in the example below. ASA2(config)# crypto ikev2 policy 1 ASA2(config-ikev2-policy)# integrity sha384
