InformationMonitor scope changes for system administrations. If the system has been properly configured to force system administrators to log in as themselves first and then use the sudo command to execute privileged commands, it is possible to monitor changes in scope. The file /etc/sudoers will be written to when the file or its attributes have changed. The audit records will be tagged with the identifier 'scope.'
Changes in the /etc/sudoers file can indicate that an unauthorized change has been made to scope of system administrator activity.
SolutionEdit or create a file in the /etc/audit/rules.d/ directory ending in .rules
Example: vi /etc/audit/rules.d/scope.rules
and add the following lines:
-w /etc/sudoers -p wa -k scope
-w /etc/sudoers.d/ -p wa -k scope
Reloading the auditd config to set active settings requires the auditd service to be restarted, and may require a system reboot.
