- `chmod 777` fixes nothing, breaks everything — find the actual owner/group issue - Setuid on scripts is ignored for security — only works on binaries - `chown -R` follows symlinks outside target directory — use `--no-dereference` - Default umask 022 makes files world-readable — set 077 for sensitive systems - ACLs override traditional permissions silently — check with `getfacl`
