Anything about security on linux. When topics are already covered in other pages, give links to them.
Setting umask
Default setting for umask on Ubuntu / Debian is 022, meaning all created files / folders are by default world readable.
To change the defaults (see [1]) to 027:
Add to /etc/sudoers:
Defaults umask = 0027 Defaults umask_override
Edit /etc/login.defs:
UMASK 027
