With the increasing number of network security breaches, we need to improve awareness regarding the security of your home network.

We simply need to follow some rules to control and prevent system penetration and also bandwidth theft (and losing money!). Safeguard your valuable information available through your home wireless connection and do not be easy target for hackers!

Here are 12 ways to boost your router’s security:

1. 1. Install your router in a safe place where the wireless signal is available only inside your own house. Avoid placing it near to a window.
2. 2. Turn off WPS, the automated network configuration method that makes your wireless password more vulnerable to hacker attacks.Turn on WPA2 encryption and, if you can, protect it with a strong password.
3. 3. Change the default admin username and password to a strong password. Do not use default passwords because they’re generated from well-known algorithms that makes hacker attacks even easier. Do not use your name, date of birth, home address or any personal information as the password.
4. 4. Upgrade your router firmware to fix known vulnerabilities of the router.
5. 5. Don’t forget to log out after managing the router, avoiding abuse of the authenticated browser sessions.
6. 6. Disable remote management of the router over the internet. In a business environment, if you need this management, it will be safer to use NAT rules allowing SSH or VPN access only.
7. 7. To prevent CSRF attacks, don’t use the default IP ranges. Change the defaults 192.168.1.1 to something different like 10.8.9.7.
8. 8. Prevent ROM-0 abuse (i.e., access to the secret data stored in your router: your ADSL login/password combination and WiFi password) of your router and forward port 80 on the router to and non-used IP address on your network. Check how-to here.
9. 9. Set your router DNS servers to automatic mode (or DHCP) or for a static value that you manually set exactly according to your ISP.
10. 10. Disable IPv6 on the router or, if you really need IPv6 services, replace the router with a IPv6 certified one.
11. 11. You can save bandwidth and allow only specific computers or devices to access your WiFi even if they have the security key to enter. Find the computer MAC address (the “physical address” listed with the command line ipconfig/all at a cmd window). Into your router settings, you should look for the Mac filtering settings to add this identifier there.
12. 12. Use a secure VPN in open/public WiFi hotspots. You can read more on how Avast SecureLine can protect PC, Mac and Android devices in these situations. If you cannot avoid using public WiFi, then try not to log in or enter your credentials (specially banking or credit card ones), but also your email and phone number. If you really need it, always prefer the secure protocol HTTPS (check the browser address bar).

When Avast Home Network Security (HNS) displays the following error: “Your network router is accessible from the Internet” that means that hackers can access your router’s administrative interface.

Your WiFi network is not secured

Although that doesn’t mean imminent threat, the fact that the router is accessible from the Internet is not good. A cybercrook could modify your network settings and even disable your Internet connection or, the worst, steal your personal data.

For sure, if you use the default password in your router, everyone can access your router. However, you won’t do that, will you? If you’re reading this article, we suppose you’re technically educated and will know that using the default password is a serious risk.

Routers, especially Small Office/Home Office (SOHO) wireless routers, are usually quite vulnerable to all sorts of exploits and exposing the admin interface of the router to the Internet is like leaving your door unlocked when you leave home. According to Tripwire, “80% of Amazon’s top 25 best-selling SOHO wireless router models have security vulnerabilities.”

Why should we worry about routers?

“Unsecured routers create an easy entry point for hackers to attack millions of American home networks,” said Vince Steckler, chief executive officer of Avast. “If a router is not properly secured, cybercriminals can easily gain access to an individual’s personal information, including financial information, user names and passwords, photos, and browsing history.”

Set up a strong password

I already explained how to make sure you have the highest level of encryption set on your router. If you missed it, please go back and read my blog, How to turn on WiFi encryption in your router settings.

The next step is to replace thedefault administrator password.Some of the most common mistakes made, not only by common users but also from a significant number of IT professionals, are to use the default administrator password and use the popular WPS and its insecure technology that allows hackers to discover (much easier) the router encryption passphrase.

When creating a new password, make sure it is long and strong, using a mix of numbers, letters and symbols. If you have many visitors to yourhome, it’s a good idea to set up a guest network with a separate password.

Eavesdropping is a major concern when we talk about the security of home WiFi networks. People around you, your neighbors in the next apartment, or even your own government, can discover anything flowing through your Internet traffic. Your personal data, like passwords and log in credentials, your credit card numbers, and  your photos and videos, are at risk.

Your WiFi network is not secured

We have written a lot about how to protect our communications using a VPN. To summarize, a Virtual Private Network, or VPN, is an encrypted tunnel where your data travels from your computer to a secure server on the Internet. Avast SecureLine is a VPN that you can use when outside of your home; at cafes, hotels, or airports.

Get your home network secure

But now, it’s time to bring your attention to your home network security. Your router should be correctly set to achieve the highest level of protection. Until you secure your router, you’re vulnerable to people accessing information on your computer, using your Internet service for free, and potentially using your network to commit cybercrimes.

There are basically three levels of security on a home router. These come in types of encryption. They are WEP, WPA and WPA2. These strange acronyms refer to different wireless encryption protocols which protect – in fact, encrypt – the information you send and receive over a wireless network.

WEP (Wired Equivalent Privacy) was the first protocol used in late 90s. It should not be used nowadays as it has serious security weaknesses which are easily hackable by even the most novice hacker. So, the first wise thing to do is move away from WEP. Your router must be quite old if you can’t do that, and you should consider purchasing an updated one, or ordering a new one from your ISP.

WPA (WiFi Protected Access) replaced WEP, but very soon after that, WPA2 replaced WPA. WPA2 implements the latest security standards, especially for data encryption with AES (Advanced Encryption Standard), a strong encryption algorithm.

Using WPA or, better, the WPA2 protocol, means that when any device tries to establish a connection to your wireless network, it will be prompted to enter the security key or password to connect.

Most wireless routers allow you to select WPA2 during the setup process. Unfortunately, the default in many wireless devices is WEP or, even worse – nothing -  which means anybody in range can connect to your WiFi to use the bandwidth and access your other devices (printer, network disk, etc.).

What to do at home

Avast Home Network Security scans for vulnerabilties.

Verify your wireless network router (or other access point) supports WPA2. If necessary, go to your router manufacturer site and search for the latest firmware to be downloaded and applied according to its instructions. Apply compatible WPA2 settings on each WiFi device, choosing the WPA2 encryption and the correct authentication info.

Although encrypting your traffic won’t protect you from rogues, denial-of-service (DNS) attacks or interference, it will ensure secure wireless communication.

Also, change the default password. Make sure the one you use is long and strong, using a mix of numbers, letters and symbols.
