Canonical Ubuntu 20.04 LTS STIG:
UBTU-20-010433
(in versions v1 r12 through v1 r1)
Title
The Ubuntu operating system must have an application firewall installed in order to control 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 control 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. Ubuntu operating system functionality (e.g., RDP) must be capable of taking enforcement action if the audit reveals unauthorized activity. Automated control of remote access sessions allows organizations to ensure ongoing compliance with remote access policies by enforcing connection rules of remote access applications on a variety of information system components (e.g., servers, workstations, notebook computers, smartphones, and tablets).
Check Content
Verify that the Uncomplicated Firewall is installed with the following command: $ dpkg -l | grep ufw ii ufw 0.36-6 If the "ufw" package is not installed, ask the System Administrator if another application firewall is installed. If no application firewall is installed, this is a finding.
Fix Text
Install the Uncomplicated Firewall by using the following command: $ sudo apt-get install ufw
