Securing a home network is a big concern nowadays. As the world is moving towards the beautiful virtual world, there are certain that are not too good for everyone at home. Everything has two sides, the good and the bad. We are always expecting the good, but we should also consider the bad.
Here in this blog, we will talk about securing our home network and our family from the bad in the virtual world.
To secure your home network, you’ll need to add an additional device “Firewall” at the internet terminating point. This will help you go ahead with the security aspects of your network. You can choose simple, pocket friendly, and easy to use firewalls like “MythGuard MGF001 – Mini Firewall“
There are following ways to secure the home network
- Analise all the network traffic going out of your home network
- Block the incoming traffic from non-genuine places
- Block traffic to and from malicious websites
- Tag all the devices being used in the network
- Keep your wireless network secured with a strong password
- Setup network alarming system
To start, lets go ahead with the above points one by one
Analise all the network traffic going out of your home network
It is a good way to get started with an analysis of the traffic of the home network first. Say, if I am living n India and the traffic hitting my home network is from China and Pakistan, it is something non-useful for me. This type of analysis can make out good results in securing and blocking traffic to and from such networks.
The analysis should include the following points
- Which device is sending traffic outside the network
- Where the data is being sent and received
- Is the IP to which the data is being sent or received under the risk category (You can check the reputation on https://talosintelligence.com/)
- Are there any unknown devices connected to the network?
- Is something unusual happening in the traffic flow of the network?
Block the incoming traffic from non-genuine places
Once you have done the analysis, you will be well known about the sources that are malicious, and that do not require either send traffic to or from the network. You can start blocking the IP addresses that you find malicious.
If you have small children in your house and you want to have a bit of parental control over the data usage, or you don’t want them to surf illegal content like pornographic data, etc. you can do it by simply blocking such category of the website in the Firewall and setting up data usage policy for your children devices. All the facilities are available in the “MythGuard MGF001 – Mini Firewall“
You can even block countries, IP range, Category wise domain names, etc. to secure the data access to and from your home network.
Block traffic to and from malicious websites
Blocking traffic to and from malicious websites is the same concept as discussed above, the difference is, you can do this by simply selecting the blocking feature generally available in all the Next Generation Firewall (NGFW). Firewalls not only block the traffic from malicious websites (blocking will include blocking of surfing, downloading, and uploading of data) but also, keep on updating the list of malicious websites.
The list gets updated and hence your network stays updated too. Security from such websites keeps you away from attacks like ransomware attacks, spoofing, phishing, etc.
Tag all the devices being used in the network
Tagging devices means, adding them to the network by binding them via MAC address. It is generally one of the best ways to secure your network. In your home network, you can evaluate the total number of devices that actually require an internet connection, and then you can connect them to the network, after connecting them to the network either via wired or wireless modes, you should bind the IP address to the MAC address of each device and block other devices to join the network.
Binding MAC address to the devices will lead to NO ADDITIONAL DEVICE in the network and thus, your wireless and wired network will be more secure, as no one standing outside your home accessing your wireless network range will be able to connect to your network. Even if he/she has the password of your wireless network.
Binding devices will also give you additional features like bandwidth motoring, access control, bandwidth control, etc.
Keep your wireless network secured with a strong password
A strong password policy is always required to keep the network secure. You should always keep a strong password for your wireless network and should always keep updating it regularly. The more complex the password is, the harder it is to guess.
A strong password also secures you from attacks like, dictionary attack, etc.
You should ensure that all the devices in the network, where ever there is a need for password protection, should have a custom password. You should not leave any of the devices on its default password setup. It can cause loopholes in your network.
Setup network alarming system
Setup an alarming system to keep yourself updated if there are any problems in your network. NGFWs have features to provide you Email and SMS-based alarms in case of different situations. You can set up alarms in situations like high bandwidth usage, network failure, a new device added to the network, etc.
This will help you monitor your home network even if you are not at your home or if you are not consistently monitoring your network. The more alarms your setup, the more secure your network will be. You will get more insights into your network.
Concluding the above, it is always suggested to keep your home network secure as we are adding up multiple devices for either personal use or home automation on regular basis. If your home network gets compromised, it can lead to severe consequences. Take a step today and go ahead securing your home network.
