CAT I

CCI(s)

CCI-000068 - Implement cryptographic mechanisms to protect the confidentiality of remote access sessions.

Weight

Fix Recommendation

Configure the SUSE operating system SSH server to use only ciphers employing FIPS 140-3-approved algorithms.

Reinstall crypto-policies with the following command:

> sudo zypper install --force crypto-policies

Set the crypto-policy to FIPS with the following command:

> sudo update-crypto-policies --set FIPS
Setting system policy to FIPS

Note: Systemwide crypto policies are applied on application startup. It is recommended to restart the system for the change of policies to fully take place.

Check Contents

Verify the SUSE operating system SSH server is configured to use only ciphers employing FIPS 140-3 approved algorithms.

To verify the ciphers in the systemwide SSH configuration file, use the following command:

> sudo grep -i Ciphers /etc/crypto-policies/back-ends/opensshserver.config
Ciphers aes256-gcm@openssh.com,aes256-ctr,aes128-gcm@openssh.com,aes128-ctr

If the cipher entries in the "opensshserver.config" file have any ciphers other than "aes256-gcm@openssh.com,aes256-ctr,aes128-gcm@openssh.com,aes128-ctr", or they are missing or commented out, this is a finding.
