Protection against surveillance

How can Comodo Firewall protecting against surveillance and other nasty attempts to breaking in your computer. I feel safe with Comodo CIS but the last time you read more and more about surveillance and attempts to retrieve data.

So how is the Firewall protecting against these attempts.

It’s a huge and complex subject. If you are genuinely interested then take a course in computer networking and IT security. Otherwise, just use CFW on default settings, don’t allow any pop-up that you don’t fully undertand. and you’ll probably be protected more than 99% of other people out there.
