I share a Linux server with several people. Is it better to change the permissions of files and directories under my home? I wonder if other or group users will have access to or even modify my files.
~/public_html, is it all right to change the permissions of all the other files and directories including hidden ones to be unreadable, unwritable and unexecutable for other and group users?
I find some directories under my home has permission like this
drwsrws---. I saw somewhere online that the
s is the
set-groupID flag. But What does
s mean actually for the group users? Is it safe to drop it?
