The SUSE operating system must have the crypto-policies package installed.

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.

SLES15 does not use the unified crypto-policies framework by default, and the crypto-policies-scripts package will need to be installed to use the framework.

Verify that the SUSE operating system uses the crypto-policies framework.

Verify that the crypto-policies packages are installed with the following command:

> sudo zypper se crypto-policies Loading repository data... Reading installed packages...

S | Name | Summary | Type ---+-------------------------+----------------------------------------+-------- i | crypto-policies | System-wide crypto policies | package i+ | crypto-policies-scripts | Tool to switch between crypto policies | package

If both "crypto-policies" and "crypto-policies-scripts" are not installed, this is a finding.

Configure the SUSE operating system to use the crypto-policies framework.

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

> sudo zypper install crypto-policies
> sudo zypper install crypto-policies-scripts
