Description
Remote access services, such as those providing remote access to network devices and information systems, which lack automated monitoring capabilities, increase risk and make remote user access management difficult at best. 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. Automated monitoring of remote access sessions allows organizations to detect cyber attacks and also ensure ongoing compliance with remote access policies by auditing connection activities of remote access capabilities, such as Remote Desktop Protocol (RDP), on a variety of information system components (e.g., servers, workstations, notebook computers, smartphones, and tablets). Satisfies: SRG-OS-000032-GPOS-00013, SRG-OS-000392-GPOS-00172

Check Text (C-223586r958406_chk)

Locate the SSH daemon configuration file which may be found in "/etc/ssh/" directory. Alternately: From UNIX System Services ISPF Shell, navigate to ribbon select tools. Select option 1 - Work with Processes. If SSH Daemon is not active, this is not a finding. Examine SSH daemon configuration file. If ServerSMF is not coded with ServerSMF TYPE119_U83 or is commented out, this is a finding.

Fix Text (F-25247r504735_fix)

Configure the SERVERSMF statement in the SSH Daemon configuration file to TYPE119_U83.
