Title

The operating system must implement DoD-approved encryption to protect the confidentiality of remote access sessions. (Cat II impact)

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, 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., RDP), thereby providing a degree of confidentiality. The encryption strength of a mechanism is selected based on the security categorization of the information. Satisfies: SRG-OS-000033-GPOS-00014

Check Content

Verify the operating system implements DoD-approved encryption to protect the confidentiality of remote access sessions. If it does not, this is a finding. Ensure telnet is disabled: $ grep telnet /etc/inetd.conf

Fix Text

Configure the operating system to implement DoD-approved encryption to protect the confidentiality of remote access sessions.
