The auditd daemon can be configured to halt the system when the audit logs are full.
In high security contexts, the risk of detecting unauthorized access or nonrepudiation exceeds the benefit of the system's availability.
Run the following commands and verify output matches:
grep space_left_action /etc/audit/auditd.conf
Expected Output:
space_left_action = email
grep action_mail_acct /etc/audit/auditd.conf
Expected Output:
action_mail_acct = root
grep admin_space_left_action /etc/audit/auditd.conf
Expected Output:
admin_space_left_action = halt
Set the following parameters in /etc/audit/auditd.conf:
space_left_action = email
action_mail_acct = root
admin_space_left_action = halt
