Taking some basic steps to secure your home Wi-Fi network will help protect your devices from getting hacked — and your information from getting stolen. The internet enables us to accomplish tasks, such as paying bills and keeping in touch with family, more efficiently and conveniently from our homes. Home users should understand and remain vigilant about the risks of being connected to the internet and the importance of properly securing home networks and systems.
A home firewall protects the devices connected to your network from intruders on the internet. Sometimes the triggers for firmware updates are news stories about significant virus attacks. The outbreak of a severe attack will motivate the router manufacturer to review its firmware codes to ensure its equipment is not vulnerable to the new attack.
How Networks Work: To and From the Internet
There’s no way we can cover exactly what you need to do to secure every type of device, so this section will be pretty high level. Some routers will do automatic firmware updates without any intervention on your part. Most routers have a built-in firewall, but you may need to activate it manually.
The steps you’ve taken so far will make your home network far more secure than most. But if you want to take this even further, here are a number of additional steps you can take. Visiting sketchy adult websites or darkweb marketplaces could expose your network to vicious attacks. Wherever possible, back up any devices that contain important information. Ideally, you would back up to a cloud storage service, or at least an external disk drive or storage array.
Step 1 – Securing the router
In this guide we laid out a basic plan for securing your home network. We divided up the work into logical areas, and covered the particular steps you can take in each to quickly increase the security of your home network. The next maintenance step is to check for updates on devices attached to your network. Update anything you can that doesn’t update itself automatically. You might as well make these checks on the same schedule as you check your router for updates. Most new computers and similar devices come from the factory jammed with pre-installed software you don’t want.
You can turn on this feature in your router’s WiFi settings, which you can access with your IP address and router login credentials. When you enable encryption for your WiFi network, it encrypts any data sent between your wireless channel and your device. As people buy ever more wirelessly connected devices, home network security has become increasingly important. Computer network security protects the integrity of information contained by a network and controls who access that information.
Use MAC address filtering to keep unwanted devices off your network
A content delivery network is a distributed server network that delivers temporarily stored, or cached, copies of website content to users based on the user’s geographic location. A CDN stores this content in distributed locations and serves it to users as a way to reduce the distance between your website visitors and your website server. Having cached content closer to your end users allows you to serve content faster and helps websites better reach a global audience.
There are a variety of password managers available, with price points ranging from too high for our taste, to free. Making the password long makes it much harder for a hacker to guess your password and log onto your network. Ideally, you should make your WiFipassword at least 12 characters long, and not comprised of a famous quote, or any kind of sentence fragment.
For larger LANs, depending on a building’s construction, you may also require multiple routers or wireless access points to ensure that the signal reaches everywhere. A network is connecting two or more computers, printers, or devices to share data and files. Nowadays, a router is the most common device used to tie together all devices in a network. All devices have either a cable or a wireless connection to the router.
Just as with your router, you need to keep each internet-connected device updated. For things like computers, phones, and tablets, you’ll want to check for and install the latest software updates before doing anything else. One option is to tell people they aren’t allowed to use your internet connection (that’ll go over real big with your friends). Just like your regular devices, your router gets firmware updates from time to time.
Although some experts disagree about when these appear with a twisted pair Ethernet cable, topologies are bus, ring, star, tree, and mesh. This knowledge may be useful when troubleshooting a home or very small office network, but these terms are mostly only relevant when setting up larger networks. The modem, whether standalone or combined, connects your network to the Internet. Just as within your network, all traffic between devices flows through the router. Similarly, all traffic from individual devices in your network that goes to the Internet and back to your devices also passes through the router. Free services like OpenDNS Home help block out "bad" sites from stealing your data.

Networks follow protocols, which define how communications are sent and received. Each device on a network uses an Internet Protocol or IP address, a string of numbers that uniquely identifies a device and allows other devices to recognize it.
