Information
If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Edit /etc/security/audit/events and add the following events to the list of audited events:
ACCT_Disable, ACCT_Enable, AUD_it, BACKUP_Export, DEV_Change, DEV_Configure, DEV_Create, FILE_Chpriv, FILE_Fchpriv, FILE_Mknod, FILE_Owner, FS_Chroot, FS_Mount, FS_Umount, PASSWORD_Check, PROC_Adjtime, PROC_Kill, PROC_Privilege, PROC_Setpgid, PROC_SetUserIDs, RESTORE_Import, TCBCK_Delete, USER_Change, USER_Create, USER_Reboot, USER_Remove, and USER_SetEnv.
Edit /etc/security/audit/config and add the ACCT_Disable, ACCT_Enable, AUD_it, BACKUP_Export, DEV_Change, DEV_Configure, DEV_Create, FILE_Chpriv, FILE_Fchpriv, FILE_Mknod, FILE_Owner, FS_Chroot, FS_Mount, FS_Umount, PASSWORD_Check, PROC_Adjtime, PROC_Kill, PROC_Privilege, PROC_Setpgid, PROC_SetUserIDs, RESTORE_Import, TCBCK_Delete, USER_Change, USER_Create, USER_Reboot, USER_Remove, and USER_SetEnv audit events to an audit class in the classes: stanza.
Edit the /etc/security/audit/config and assign the audit classes with the ACCT_Disable, ACCT_Enable, AUD_it, BACKUP_Export, DEV_Change, DEV_Configure, DEV_Create, FILE_Chpriv, FILE_Fchpriv, FILE_Mknod, FILE_Owner, FS_Chroot, FS_Mount, FS_Umount, PASSWORD_Check, PROC_Adjtime, PROC_Kill, PROC_Privilege, PROC_Setpgid, PROC_SetUserIDs, RESTORE_Import, TCBCK_Delete, USER_Change, USER_Create, USER_Reboot, USER_Remove, and USER_SetEnv events to the all users listed in the users: stanza.
