With so many potential weak points in a network, it's hard to know if everything is properly secured. Is your connection secure, and how would you know where the flaws lie?

Here's how to check if your network is secure so you can have peace of mind.

The first port of call for checking your internet security is the firewall. The firewall's main job is to protect the ports on your computer from unwanted visitors. As such, it's a good idea to test these ports to ensure unauthorized connections can't creep through.

Fortunately, you don't need to pay a hacker to attack your firewall. Services such as ShieldsUp! prod at your computer's ports and report back if it breaches your defenses. If your firewall doesn't protect you, it's worth trying a more secure one. We covered the the best computer security and antivirus tools, so be sure to check them out if your current one fails you.
