The F5 BIG-IP appliance IPsec VPN must be configured to use FIPS-validated SHA-2 or higher for Internet Key Exchange (IKE).
High Severity
<VulnDiscussion>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 must not be configured to use SHA-2 for integrity of remote access sessions. This requirement is applicable to the configuration of IKE Phase 1 and Phase 2.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
