Ubuntu security checklist?
For a new Ubuntu box, what would be the security checklist for a new box?

1. Use a firewall. 2. Learn to properly use UNIX permissions and make sure you always use the fewest permissions needed. A lot of newbies will "chmod 777" a file or directory when they have permission issues, which is very bad. 3. Use your machine as a normal user and not as root. Learn to use sudo. 4. Remove and disable any un-needed services. For example, if you don't need a mail server running, remove postfix. 5. Use TCP wrappers to lock down serviced you do need available. There are a lot of general rules too, like use a strong password, encrypt sensitive data (TrueCrypt), keep regular backups, etc. That should get your started, but do a lot of google research too. |
You might want to have a look at the Security References as well.

And I see you are doing web application development... That means you will need to become somewhat of a security expert. Always sanitize your inputs!!!

Most of the info in Securing Debian Manual - http://www.debian.org/doc/manuals/se...-debian-howto/ would probably apply to Ubuntu as well.
