I’ve become increasingly paranoid about my home network security and am wondering what a firewall is and whether I should enable the one on my router?

I go to the public library to work on my memoirs. I have my own computer, an ancient Windows system, but since I don’t have Internet, I appreciate that it’s free at the library. But is it safe when I go online?
It’s an unfortunate fact that web security sometimes gets lost in the excitement of setting up a new website or blog, the thought of finally having a storefront for your craft takes precedence over protection from SQL injections and Distributed Denial of Service (DDoS) attacks – as if anybody knows what they are anyway. Foregoing website, server, and/or database protection creates a false economy though; online threats are increasingly a concern for everybody who has a website.
I want to log in to my Comcast cable box and change its wifi settings. But when I try to connect, I don’t know the password to change things in the first place. Help!
Public wifi is risky, even when there’s a password: If other people at the library, coffee shop or even shared office location are using the same network, you have access to each other’s traffic. Enter a technology called virtual private network or VPN, that secures your connection regardless of network.
And while some are tricky to work with, I tried out ExpressVPN on my MacBook Pro and was impressed with how easy it was to use…
I’ve become paranoid about security on my Mac laptop and just bumped into a story about some hackers who claim that they can break into a Mac laptop via the wifi connection. Yikes! How do I disable the hole so that no-one can use this exploit to get into my computer??
A question about DMZ’s: We run a privately addressed network (192.168…) on a workgroup. We have a server running DHCP. If I set up a DMZ on a managed switch I would like to know if a potentially infected (spyware/trojans) PC which is then plugged into it would be able to infect the server.
