A firewall is a device that acts like a security cop watching over your computer network to detect unauthorized access and activity. Every business and individual needs one.
But take heed! A firewall is completely useless if it’s not set up or maintained properly. Your firewall needs to be upgraded and patched on a continual and consistent basis. Also, security policies and configurations need to be set.
This is not something you want to try and handle on your own. You are best served by letting the pros (companies like Computerware) handle it for you.
If you’re a managed IT client, you’re covered. If not, take immediate action to correct the error of your ways.
