Add auditctl Example

This command allows you to watch a file for changes.

watch_file_for_changes_auditctl.sh

+# Add a watch to the /etc/hosts file watching for (-p) reads, writes, executions,
+# and appends named (-k) hosts-file which can be uniquely used to identify the
+# audit records produced by this rule. Check the /var/log/audit/audit.log file
+# for matching events.
+sudo auditctl -w /etc/hosts -p rwxa -k hosts-file
+
+# To remove the rule later change the -w to -W with the rest of the command being
+# the same. If you want to list all rules auditctl -l will show you all rules
+# currently loaded.
