apk audit - audit directories for changes

apk audit [<options>...] directories...

apk audit audits the system or specified directories for changes compared to the package database.

The audit can be done against configuration files only (--backup) to generate list of files needed to be stored in the overlay in run-from-tmps configuration. Alternatively, it can audit all installed files (--system or --full) to e.g. detect unauthorized modifications of system files.

By default, the output format is one file per line, for each modified file. A character is printed indicating the line type, followed by a space, then the affected path or details. The changes detected are:

- Database detail record
+ On-disk detail record
A File added
d Directory added
D Directory added (with non-listed files/subdirs)
e error occured during audit (e.g. no permissions to read file)
M File metadata changed (uid, gid, or mode)
m Directory metadata changed
U File contents modified
X File deleted
x xattrs changed

--backup

Audit configuration files only (default). The list of files to be audited is generated from the masks in protected_paths.d.

--check-permissions

Check file permissions too. Namely, the uid, gid and file mode will be checked in addition to the file content.

--details

Enable reporting of detail records.

--full

Audit all system files. Same as --system, but in addition reports all added directories and files. A built-in default override for protected paths is used, unless a --protected-paths is explicitly specified.

--ignore-busybox-symlinks

Ignore symlinks whose target is the busybox binary.

--packages

Print only the packages with changed files. Instead of the full output each modification, the set of packages with at least one modified file is printed.

To repair all packages with modified files, one could use:

apk audit --packages -q | xargs apk fix

--protected-paths FILE

Use given FILE for protected paths listings. This also makes apk ignore the regular protected_paths.d directories.

--system

Audit all system files. All files provided by packages are verified for integrity with the exception of configuration files (listed in protected_paths.d). This is useful detecting unauthorized file changes. New files or directories are not reported.

-r, --recursive

Descend into directories and audit them as well.
