Master The Linux
Filesystem Permissions

... when it comes to file-permissions, you can make exactly two types of mistakes: You can give to few permissions or to many.


If you give to few, then you'll get an error right away. You'll realize you have a problem and you can solve it.

If you - on the other hand - give to many permissions, then your tasks will work as expected - but at the same time data will be silently exposed o the wrong people. That may be confidential data, personal data, passwords ... and you won't even notice until it's too late ...
