You may have already enabled the firewall feature on your PC or wireless router, but how do you know if it is working properly?
Test your firewall to make sure it is working
The main purpose of a personal network firewall is to protect everything behind it from harm, especially hackers and malware.
When implemented correctly, a network firewall makes your PC invisible to hackers. If they can't see your computer, they can't target you.
Hackers use port scanning tools to scan computers with open ports that may contain vulnerabilities. This allows hackers to create a backdoor into your computer.
