The VPN Gateway must be configured to use IPsec with SHA-2 at 384 bits or greater for hashing to protect the integrity of remote access sessions.

Description
Without strong cryptographic integrity protections, information can be altered by unauthorized users without detection. SHA-1 is considered a compromised hashing standard and is being phased out of use by industry and government standards. DOD systems must not be configured to use SHA-1 for integrity of remote access sessions. The remote access VPN provides access to DOD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network.

Details

Check Text (C-207192r916146_chk)

Verify the VPN Gateway uses IPsec with SHA-2 at 384 bits or greater for hashing to protect the integrity of remote access sessions. If the VPN Gateway does not use IPsec with SHA-2 at 384 bits or greater for hashing to protect the integrity of remote access sessions, this is a finding.

Fix Text (F-7452r916145_fix)

Configure the VPN Gateway to use IPsec with SHA-2 at 384 bits or greater for hashing to protect the integrity of remote access sessions.
