UBTU-18-010410 - The Ubuntu operating system must monitor remote access methods - daemon.notice

Information

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).

Solution

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
