You should think of how an onion has rings when thinking of security in a home network. You must go through each layer to get to the center.
It is the practice of using multiple defense mechanisms to protect your data/information. If the first layer is breached, the next layer is now your protection.
We already do this with important documents/valuables in our homes. For example, we have a fence around our home to create a barrier. We put locks on our doors and windows. Lastly, we put important items in a safe that has a combination code.
The same should be true in the digital world. Here are some examples of layers that I’ve used.
1st Layer – Firewall / Router
Keep your router up-to-date with the latest firmware. Check if your router is supported by the manufacturer. If it isn’t, it may be time to replace your router. Your firewall/router controls who is allowed access to your network.
2nd Layer – Security Software
Some devices are safer than others. Windows has always been a bigger target for hackers, and that’s not to says that Windows is bad. Since most businesses use Windows, there are more opportunities to take advance of.
Having some type of protection software on your computer is a must for Windows. Good thing if you are using Windows 10, it already comes with security software built-in. When you get notified of pending patches, install them.
3rd Layer – Data Backups
Make copies of files that are important to you. Backup all things that cannot easily be recovered. If you take pictures or video, back that up. Or you can be a musician and have audio recordings. Anything that you’ve created should be in your backup plan. Find out more about data backups.
4th Layer – Physical Security
Lock your screen when you leave your computer unattended, this is neglected a lot of the time. This is more of an issue in the workplace where others could get access to your computer. But it’s good practice to do at home as well. You should also keep any kind of storage device (portable hard drive, USB flash, NAS, etc…) in an out of site location.
Buy using multiple security layers, you protect your information. These are just 4 layers, but you can have as many layers as you see fit. Think of what is important to you and how you are protecting it. Just be sure that the approach you take includes data backups. Make backups now, it is the most important of all of the things I talked about today.
