Removing others' read permissions...

English Install/Boot/Login

I’m running openSUSE on a gateway server and would like to remove read permissions wherever practical. I’m tempted to do something like chmod -R o-r /* but then I thought, “What if a vital service needs to read one of these files?”

So, that’s why I’ve created this thread. If I do this, am I going to stop my server booting/working? How can I determine what files need global read permissions?

Oh jesus craps, you do NOT want to run that command.

If you want to secure your system, examine the “Paranoid” setting in the Permissions under YAST / Security and Users / Local Security.

Yeah, I realized that command would be a rather bad idea…

Thanks for the tip! Most useful :slight_smile:
