Hi! I am new to UberStudent; came from Windows 7.
Where is the firewall / is there a firewall? How do I turn it on (or is it on by default - hopefully?)? I've tried searching, but no firewall info appears.

Client-based firewalls are absolutely not the way to have security, even though some Windows software makers might want you to think otherwise so they can make money from you.

From where do you most connect to the Internet? If from home, you really need to use a router as a firewall. If from school or somewhere you are connecting through wireless, then you're already behind a firewall.

Myself, I have this inexpensive wireless router and run all connections in the home through it, using the router's guide to block what I wish, or you can just accept the sane defaults for the firewall. I also run everything through OpenDNS (it's free for personal use), which I set inside the router.

That said, although I don't recommend a client-bassed approach, you can install a client-based firewall by hitting F12 on your keyboard and running:

Code:
sudo apt-get install gufw

A program, Firewall Configuration, will place itself in to your menu at System > Administration.

A firewall is nothing more then a bunch of programs or files containing a few "lists" that determines if that object should be accessed by a computer or not.
These "lists" are called Access Control lists (ACLs) because they control access to those objects by denying or allowing access.

To any window user, you would see the windows firewall with "deny" or "allow" options, it may include options to deny a program or allow it for a set time.
But in truth, Behind the interface you see, contains multiple Access Control lists with simple options to allow a program or deny programs in a list.
Windows by default adds some programs that need communication access to networks such as windows update.

Linux has many ACLs (Firewalls) which allows very strong security. You are protected by default.

Only super restrictive server designs would require even professionals to touch the firewall in linux. It is not going to be an issue for an average user.

Does anyone recommend a specific Hardware Firewall ? I've been told ERPOE-5 - EdgeRouter was pretty good.
