Assessment Title
Rule Text
AOS, when used as a 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
Discussion Text
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. DoW systems must not be configured to use SHA-1 for integrity of remote access sessions.
The remote access VPN provides access to DoW nonpublic information systems by an authorized user (or an information system) communicating through an external, nonorganization-controlled network.
Satisfies: SRG-NET-000063-VPN-000220, SRG-NET-000074-VPN-000250, SRG-NET-000168-VPN-000600, SRG-NET-000230-VPN-000780
