Title

The operating system must monitor remote access methods. (Cat II impact)

Discussion

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

Check Content

Verify the operating system monitors remote access methods. If it does not, this is a finding. SSH does this by default to syslog auth. Verify that SSH is enabled: $ grep sshd /etc/rc.conf sshd_enable=YES If sshd_enable=YES does not appear in this list, this is not a finding. Verify logging configuration: $ grep -i log /etc/ssh/sshd_config # Logging SyslogFacility AUTH LogLevel INFO If LogLevel is set to "QUIET", this is a finding.

Fix Text

Configure the operating system to monitor remote access methods.
