Description
Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote access (e.g., RDP) 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. 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.

Check Text (C-279536r1192381_chk)

Note: For AHV, this requirement is Not Applicable. Verify AOS, Prism Central, and Files OS VMs are configured to only use DOD-approved TLS encryption using the following command. $ sudo grep -i MinProtocol /etc/crypto-policies/back-ends/opensslcnf.config TLS.MinProtocol = TLSv1.2 DTLS.MinProtocol = DTLSv1.2 If the "TLS.MinProtocol" is not set to "TLVSv1.2" (or later) or the "DTLS.Min.Protocol" is not set to "DTLSv1.2", this is a finding.

Fix Text (F-83994r1192289_fix)

Configure SSH. 1. For AOS, configure SSH, then restart the SSH for the changes to take effect. $ sudo salt-call state.sls security/CVM/sshdCVM $ sudo systemctl restart sshd 2. For Prism Central, configure SSH, then restart the SSH for the changes to take effect. $ sudo salt-call state.sls security/PCVM/sshdPCVM $ sudo systemctl restart sshd 3. For Files, configure SSH, then restart the SSH for the changes to take effect. $ sudo salt-call state.sls security/AFS/sshdAFS $ sudo systemctl restart sshd
