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). |

Verify that the Ubuntu operating system monitors all remote access methods. Check that remote access methods are being logged by running the following command: $ grep -E -r '^(auth,authpriv\.\*|daemon\.\*)' /etc/rsyslog.* /etc/rsyslog.d/50-default.conf:auth,authpriv.* /var/log/auth.log /etc/rsyslog.d/50-default.conf:daemon.* /var/log/messages If "auth.*", "authpriv.*" or "daemon.*" are not configured to be logged in at least one of the config files, this is a finding. |

Configure the Ubuntu operating system to monitor all remote access methods by adding the following lines to the "/etc/rsyslog.d/50-default.conf" file: auth.*,authpriv.* /var/log/secure daemon.* /var/log/messages In order for the changes to take effect the "rsyslog" service must be restarted with the following command: $ sudo systemctl restart rsyslog.service |
