Do You Need A Firewall At Home

Firewall

Let’s face it we all worry about identity theft. So you take the time to watch for little locks in front of a website address before you buy anything online. We feel around the card slot at gas stations before we slide our card into the slot. Maybe you even watch the waiter or waitress as they walk away with your card at a restaurant? But what about when you are at home on your own wireless with your own Internet connection and your trusty tablet sitting on your couch. Are you SAFE?

Really the answer has to be NO! Let’s look at it this way. You walk into your house and before you go to bed you lock the front door and make sure your windows are locked. Even your car sitting outside is locked up tight. But many of us leave another path right into our private lives. Your Internet line coming into your house is always on and ready for your use. But my friends it is also always on and allowing others into your house. So that password list that you keep in that folder called HIDDEN or PRIVATE can be accessed by anyone in the world. How about that baby monitor with that cute camera that you can watch little Jr. sleeping? So can anyone else in the world. I have even heard that people are now listening to your conversions at home using your Amazon or Google devices. So what can you do?

Well, we could pull the plug on the Internet whenever we are not using it? Really not the best idea because our computers and phones get updates when we sleep. No, a better way is to install a Firewall at home. We once thought these were just for business. But in reality, you have more private information then what you have on your work computer right in your own homes. Okay, so you might be saying I don’t know anything about this Firewall stuff? I can help with that. Please contact me and we can find a cost-effective way to secure your home or even small business with a Firewall that will keep you and your family safe and allow you to sleep at night knowing no one is watching or listening to you!

Network Firewalls

Firewall

Network firewalls are built to keep the bad guys out of your network while allowing your users to maintain high availability to the Internet resources they wish to use. Setting up a corporate firewall takes time and some planning. Your first objective should be to know what to allow to come into your network from the outside world. I begin with a drawing like the one above. When you allow traffic from the outside world you should only allow a direct connection from the company or service you wish to use. Next we begin to write up any static routes we might need. These items might be a mail server or maybe your web server. Also remember after you setup the static routes you then open the correct ports to that internal IP address. Remember to allow any internal traffic to go out of your network. One tip to keep in your back pocket is if you ever get a rouge machine on your network spamming emails. If you use off site email services simply deny port 25 SMTP traffic from going out of your network. Planning is everything so that you don’t run into issues using the Internet. The last word of advice is to revisit your firewall configuration at least once ever six months. Also buy a firewall large enough to pass the bandwidth that you have, you don’t want it to become a bottle neck for your Internet traffic.

Protect Your Computer

With all of this talk about the NSA or National Security Agency watching everything we do and monitoring all of our cell phone calls, don’t you want to protect your computer from prying eyes?

Okay now I don’t really believe that the government has the time of day to watch what I am doing on the Internet. But I know there are millions of hackers in this world that would like to get into everyones computers. They enjoy digging and looking for useful information.

We could talk about a thousand reasons to protect your computer, but what I teach people is that you want to protect your computer so that you can sleep at night.

The easiest way to protect your computer is to be sure you have the firewall turned on. On Windows you can find the firewall in the Control Panel then under Security. On the Mac, you will find it under Preferences and Security/Privacy.

What does a firewall do? Simply allows you to put up a virtual brick wall between your computer and the Internet. Although not non-hackable but a small brick wall is better then no wall at all. Now turn on those firewalls!
