Vulnerability Discussion

Centralized cryptographic policies simplify applying secure ciphers across an operating system and the applications that run on that operating system. Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data.

Check

Verify that the RHEL 9 crypto-policies package is installed with the following command:

$ dnf list --installed crypto-policies

Example output:

crypto-policies.noarch 20240828-2.git626aa59.el9_5

If the crypto-policies package is not installed, this is a finding.

Fix

Install the crypto-policies package (if the package is not already installed) with the following command:

$ sudo dnf -y install crypto-policies
