Canonical Ubuntu 24.04 LTS STIG:
UBTU-24-100400
(in version v1 r1)
Title
Ubuntu 24.04 LTS must have the "auditd" package installed. (Cat II impact)
Discussion
Without establishing the when, where, type, source, and outcome of events that occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit record content that may be necessary to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked. Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. Successful incident response and auditing relies on timely, accurate system information and analysis to allow the organization to identify and respond to potential incidents in a proficient manner. If Ubuntu 24.04 LTS does not provide the ability to centrally review Ubuntu 24.04 LTS logs, forensic analysis is negatively impacted. Associating event types with detected events in Ubuntu 24.04 LTS audit logs provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured operating system.

Check Content
Verify the audit service is configured to produce audit records with the following command: $ dpkg -l | grep auditd ii auditd 1:3.0.7-1build1 amd64 User space tools for security auditing If the "auditd" package is not installed, this is a finding.
Fix Text
Configure the audit service to produce audit records containing the information needed to establish when (date and time) an event occurred. Install the audit service (if the audit service is not already installed) with the following command: $ sudo apt install -y auditd
