Critical Risk

- Even the owner cannot modify this file without changing permissions first.
- Scripts need read permission to run; only compiled binaries can be executed without it.
- Unusual: a lower class has permissions the class above it lacks.
Common Use Cases
113 is uncommon in standard Linux setups. The closest widely used permission is chmod 711.
