A Case Study: Let us take a look at the wireless network as an example. Almost every member of the family accesses it through laptops, PCs, cell phones and tablets. With the Internet of Things, there is a gamut of other elements in the home that access the Wi-Fi. In your home Wi-Fi network, even a minor vulnerability can give a malicious user access to almost all the devices that access that Wi-Fi. This could spell trouble for your access to bank accounts, credit card details, child safety, and a whole lot of other concerns.
Remedies for a Safer Wi-Fi
The following tips can help secure your home Wi-Fi network against unauthorized access.
1. Change the default name of your home Wi-Fi
The first step towards a safer home Wi-Fi is to change the SSID (service set identifier). SSID is the network’s name. Many hardware manufacturers give all their wireless routers a default SSID. In most cases, it is their company’s name. When a computer with a wireless connection searches for and displays the wireless networks nearby, it lists each network that publicly broadcasts its SSID. This gives a hacker a better chance of breaking into your network. It is better to change the network’s SSID to something that does not disclose any personal information thereby throwing hackers off their mission.
2. Make your wireless network password unique and strong
Most wireless routers come pre-set with a default password. This default password is easy to guess by hackers, especially if they know the router manufacturer. When selecting a good password for your wireless network, make sure it is at least 20 characters long and includes numbers, letters, and various symbols. This setting will make it difficult for hackers to access your network.
3. Enabling network encryption
Almost all wireless routers come with an encryption feature. By default, it is turned off. Turning on your wireless router’s encryption setting can help secure your network. Make sure you turn it on immediately after your broadband provider installs the router. Of the many types of encryption available, the most recent and effective is “WPA2.”
4. Turn off network name broadcasting
When using a wireless router at home, it is highly recommended that you disable network name broadcasting to the general public. This feature is often useful for businesses, libraries, hotels, and restaurants that want to offer wireless Internet access to customers, but it is usually unnecessary for a private wireless network.
5. Keep your router’s software up to date
Sometimes router’s firmware, like any other software, contains flaws that can become major vulnerabilities unless they are quickly fixed by firmware releases from the manufacturer. Always install the latest software available on the system and download the latest security patches to ensure no security hole or breach is left open to online predators.
6. Make sure you have a good firewall
A “firewall” is designed to protect computers from harmful intrusions. Wireless routers generally contain built-in firewalls but are sometimes shipped with the firewall turned off. Be sure to check that the wireless router’s firewall is turned on. In case your router doesn’t have such a firewall, make sure you install a good firewall solution on your system to watch for malicious access attempts to your wireless network.
7. Use VPNs to access your network
A virtual private network, or VPN, is a group of computers or networks that work together globally over the Internet. Individuals can use VPNs, such as Norton WiFi Privacy as a way for you to secure and encrypt their communications through the internet, anonymously. When you connect to a VPN, a VPN client is launched on your computer browser. When you log in with your VPN credentials, your computer exchanges keys with another server within the subscribedVPN. Once both computers have verified each other as authentic, all your Internet communication is encrypted and secured from outside prying.
Most of all, check what devices connect to your home network and make sure they have reliable security software like Norton Security installed against viruses and spyware.
