Vulnerability discussion

Without cryptographic integrity protections, information can be altered by unauthorized users without detection.To protect the integrity of the authenticator and authentication mechanism used for the cryptographic module used by the Central Log Server must be configured to use one of the following hash functions for hashing the password or other authenticator in accordance with SP 800-131Ar1: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256, SHA3-224, SHA3-256, SHA3-384, and SHA3-512.Applications also include HMAC, KDFs, Random Bit Generation, and hash-only applications (e.g., hashing passwords and using SHA-1 or higher to compute a checksum). For digital signature verification, SP800-131Ar1 allows SHA-1 for legacy use where needed.

Check content

Examine the configuration. Verify the Central Log Server is configured to use FIPS-validated SHA-1 or higher hash function to protect the integrity of keyed-hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, hash-only applications, and digital signature verification (legacy use only). If the Central Log Server is not configured to use FIPS-validated SHA-1 or higher hash function to protect the integrity of keyed-hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, hash-only applications, and digital signature verification (legacy use only), this is a finding.

Fix text

Configure the Central Log Server to use FIPS-validated SHA-1 or higher hash function to protect the integrity of keyed-hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, hash-only applications, and digital signature verification (legacy use only).

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
