While hardening a server, you run chattr against /var/audit/audit.log to prevent the file's existing records from being altered or deleted, but you still need the audit daemon to continue writing new events to the same file. Which attribute flag accomplishes this goal?
The append-only attribute (+a) allows write operations only in append mode. Once the flag is set, the kernel refuses any attempt to overwrite, truncate, rename, or delete the file, yet processes that open the file with O_APPEND can still add data. This satisfies the requirement that historical audit entries remain intact while new entries are still recorded.
The immutable flag (+i) is more restrictive: it blocks all changes, including appending, so the audit daemon would fail. The no-atime flag (+A) merely stops access-time updates and offers no protection against modification or deletion. The no-dump flag (+d) only prevents the file from being included in dump-style backups and does not stop edits or removal.
