Discussion

Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DOD nonpublic information systems by an authorized user (or an information system) communicating through an external, nonorganization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless. Encryption provides a means to secure the remote connection to prevent unauthorized access to the data traversing the remote access connection (e.g., RDP), thereby providing a degree of confidentiality. The encryption strength of a mechanism is selected based on the security categorization of the information. The operating system must use cryptographic modules that have been validated by NIST's FIPS 140-3 program. Using weak or untested cryptography could compromise the confidentiality and integrity of data at rest and in transit.

Verify that AlmaLinux OS 9 is in FIPS mode with the following command:

$ fips-mode-setup --check

FIPS mode is enabled.

If FIPS mode is not enabled, this is a finding.
