Title
The OS X system must implement DoD-approved encryption to protect the confidentiality and integrity of remote access sessions including transmitted data and data during preparation for transmission. (Cat I impact)
Discussion
Without confidentiality and integrity protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD non-public information systems by an authorized user (or an information system) communicating through an external, non-organization-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., Remote Desktop Protocol [RDP]), thereby providing a degree of confidentiality. The encryption strength of a mechanism is selected based on the security categorization of the information.

Check Content
For systems that allow remote access through SSH, run the following command: /usr/bin/sudo /bin/launchctl print-disabled system | /usr/bin/grep com.openssh.sshd If the results do not show the following, this is a finding. "com.openssh.sshd" => false
Fix Text
To enable the SSH service, run the following command: /usr/bin/sudo /bin/launchctl enable system/com.openssh.sshd The system may need to be restarted for the update to take effect.
