ALMA-09-043140 - AlmaLinux OS 9 must implement DOD-approved encryption in the bind package.

Information

Without cryptographic integrity protections, information can be altered by unauthorized users without detection.

Cryptographic mechanisms used for protecting the integrity of information include, for example, signed hash functions using asymmetric cryptography enabling distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash.

AlmaLinux OS 9 incorporates systemwide crypto policies by default. The employed algorithms can be viewed in the /etc/crypto-policies/back-ends/ directory.

Solution

Configure BIND to use the systemwide crypto policy.

Add the following line to the "options" section in "/etc/named.conf":

include "/etc/crypto-policies/back-ends/bind.config";
