Description
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. RHEL 9 incorporates system-wide crypto policies by default. The employed algorithms can be viewed in the /etc/crypto-policies/back-ends/ directory. Satisfies: SRG-OS-000423-GPOS-00187, SRG-OS-000426-GPOS-00190

Check Text (C-258242r958908_chk)

Verify that BIND uses the system crypto policy with the following command: Note: If the "bind" package is not installed, this requirement is Not Applicable. $ sudo grep include /etc/named.conf include "/etc/crypto-policies/back-ends/bind.config";' If BIND is installed and the BIND config file doesn't contain the include "/etc/crypto-policies/back-ends/bind.config" directive, or the line is commented out, this is a finding.

Fix Text (F-61907r926712_fix)

Configure BIND to use the system crypto policy. Add the following line to the "options" section in "/etc/named.conf": include "/etc/crypto-policies/back-ends/bind.config";
