Router security: How to setup Wi-Fi router securely | Norton

[1221alan]

Wireless internet or Wi-Fi access has become a necessity in the home and workplace, but it can also open a door to risks from hackers, scammers, and identity thieves. Whether in your home or office, an unsecured Wi-Fi router running on the default manufacturer settings could be a liability when it comes to hackers and Wi-Fi squatters accessing your private information and burdening your broadband.

If your Wi-Fi network isn’t secured properly — a public IP address, no unique Wi-Fi password — you could be letting anyone with a wireless-enabled device gain access. You might not be worried about someone using your wireless connection, but the real risk is exposing sensitive information you send and receive — your emails, banking information, and maybe even your smart home’s daily schedule — to cybercriminals.

Basic router security
Every router should have a strong password to help keep out the bad guys. Some new routers come with default passwords, but you should change these during setup. Creating a new, complex, unique password for your wireless router is easy. It should only take a couple of minutes. Specific instructions vary from one router to another, but the basic idea is this:

All wireless routers have a numerical address. If you’ve lost the instructions, you can probably find yours by searching online for your router’s model number.
In Security Settings, create a name for the router, and a password, and then select a type of encryption, like WAP2. Do not name your router something that can easily be associated with you, such as your last name.
Make sure you choose a complex password that you can remember, but one that’s not easy to guess.
Don’t forget to save the updated information when prompted. Your router is now secured against roaming cybercriminals.
Different types of encryption
Depending on your router, you might have options for different kinds of encryption. The most common router encryption types are WEP, WPA and WPA2. Commercial routers from brands like Netgear, Linksys, and ASUS often include:

Wired Equivalent Privacy (WEP): This is the oldest and most popular form of router encryption available. However, it is the least secure of all encryption protocols. It uses radio-waves that are easy to crack. For every data packet that is transmitted it uses the same encryption key. With the help of automated software, this information can easily be analyzed.
Wi-Fi Protected Access (WPA): The Wi-Fi Alliance came up with WPA to offer an encryption protocol without the shortcomings of WEP. It scrambles the encryption key thereby getting rid of the problems caused by hackers cracking the radio-waves. This is also a less secure form of encryption, partly because of legacy hardware and firmware that still used WEP as their main protocol. However, it is a significant improvement over WEP.
Wi-Fi Protected Access 2 (WPA2): This encryption type is currently the most secure and most recent form of encryption available. You should always select WPA2 if it is available. It not only scrambles the encryption key but is also does not allow the use of Temporal Key Integrity Protocol or TKIP which office.com/setup | mcafee.com/activate | norton.com/setup

is known to be less secure then AES.
Advanced Encryption Standard: When possible, you’ll want to use AES on top of WPA2 or WPA. This is the same type of encryption used by the federal government to secure classified information. Routers made after 2006 should have the option to enable this on top of WPA2.
How to set up Wi-Fi router securely: The specifics
Manufacturers know how important it is to make their products user-friendly. Most routers come with instructions that are easy to set up and configure. Apps are replacing bulky user manuals and web interfaces that walk users through the set-up process. While using apps has made setting up routers easier for customers, the router may not be completely secure. Here are a few things to consider before setting up the router.

Update your router with new firmware and keep it up to date

Updating your router’s firmware is an important security measure to help protect your router against the latest threats. Most modern routers allow you to enable notifications to prompt you when the manufacturer makes patches and updates to the router’s firmware available. Some manufacturers may even push the update automatically to your hardware, so you don’t have to do anything. However, there are some routers that have updates within the settings option. In this case, the user has to make sure that the firmware is manually updated regularly.

Change your login credentials and router password

Traditional routers come with a default password created by the manufacturer. While it may look complex and resistant to hacking, there is a good chance most models of the same router share the same password. These passwords are often easy to trace or find on the internet.

Make sure you change the password of your router during setup. Choose a complex alphanumerical password with multiple characters. If possible, change the username of your network, too. After all, it makes up half of the log-in credentials.

Always use WPA2 to secure your wireless network

Wi-Fi Protected Access 2, better known as WPA2, is a commonly used network security technology used on wireless routers.

It is one of the most secure encryption options available in the market since 2006. WPA2 scrambles the traffic going in and out of the router. That means even if someone is within range and can see traffic, all they see is the encrypted version.
