Description
Control of program execution is a mechanism used to prevent execution of unauthorized programs. Some operating systems may provide a capability that runs counter to the mission or provides users with functionality that exceeds mission requirements. This includes functions and services installed at Ubuntu 24.04 LTS-level. Some of the programs, installed by default, may be harmful or may not be necessary to support essential organizational operations (e.g., key missions, functions). Removal of executable programs is not always possible; therefore, establishing a method of preventing program execution is critical to maintaining a secure system baseline. Methods for complying with this requirement include restricting execution of programs in certain environments, while preventing execution in other environments; or limiting execution of certain program functionality based on organization-defined criteria (e.g., privileges, subnets, sandboxed environments, or roles). Satisfies: SRG-OS-000312-GPOS-00124, SRG-OS-000368-GPOS-00154, SRG-OS-000370-GPOS-00155

Who does this work

8 NICE work roles and 8 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-270659r1066466_chk)

Verify Ubuntu 24.04 LTS has AppArmor installed with the following command: $ dpkg -l | grep apparmor ii apparmor 4.0.1really4.0.1-0ubuntu0.24.04.3 amd64 user-space parser utility for AppArmor ii libapparmor1:amd64 4.0.1really4.0.1-0ubuntu0.24.04.3 amd64 changehat AppArmor library If the AppArmor package is not installed, this is a finding.

Fix Text (F-74593r1066465_fix)

Install "AppArmor" with the following command: $ sudo apt install apparmor Note: AppArmor must have properly configured profiles for applications and home directories. All configurations will be based on the actual system setup and organization and normally are on a per role basis. Refer to the AppArmor documentation for more information on configuring profiles.
