If you own a computer, you likely use Wi-Fi to connect to the internet. However, connecting to an unsecured network can leave your computer vulnerable to malicious attacks. In this blog, we'll discuss how you can secure your Wi-Fi network and protect your computer from unauthorized access.

What is Wi-Fi Security?

Wi-Fi security measures are designed to protect wireless networks from unauthorized access by encrypting data transmitted over the network. Wi-Fi security is an essential element of wireless network security, and without it, attackers can easily intercept your data, including username and password information, email messages, etc.

Wi-Fi networks can use several types of encryption to protect your valuable data. The most common encryption types are WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2 (Wi-Fi Protected Access II). These protocols create a secure communication channel between your computer and the Wi-Fi router.

Why is Wi-Fi Security Important?

Security is essential for any wireless network, especially Wi-Fi networks. Without proper security measures, attackers can easily access your data, including personal information, banking details, emails, and more. Additionally, attackers can use your Wi-Fi network to launch attacks on other devices connected to the internet through your router.

Additionally, if your Wi-Fi network is unsecured, it will be much easier for others in your vicinity to use your internet without your knowledge. This is because they will be able to gain access to the network and bypass any controls you have in place. This can lead to slower internet speeds as well as increased security risks, making it essential to secure your network.

How Can I Secure My Wi-Fi Network?

There are several ways to secure your Wi-Fi network successfully. You may need to implement several of these methods to get the most comprehensive protection. At JTG Systems, we recommend the following to secure your Wi-Fi network:

Change the Default Password

Most Wi-Fi routers come with default usernames and passwords that can be easily found online. Changing the default password is the first and most crucial step in securing your Wi-Fi network. Always use a complex password that is difficult to guess.

Enable Network Encryption

As we mentioned earlier, network encryption protects your data from attackers by creating a secure communication channel between your computer and the Wi-Fi router. WPA2 is currently the most secure encryption protocol, and we recommend using it over WEP or WPA whenever possible.

Disable WPS

WPS (Wi-Fi Protected Setup) is an easy way to connect new devices to your Wi-Fi network without entering a password. However, this convenience can leave your network vulnerable. Disabling WPS is an important step in securing your Wi-Fi network and preventing unauthorized access.

MAC Address Filtering

MAC (Media Access Control) Address Filtering is a feature of most Wi-Fi routers that allows you to control which devices can connect to your network. You can create a list of approved MAC addresses and only allow those devices to connect to your Wi-Fi network. Unfortunately, MAC Address Filtering is not very secure on its own because hackers can easily spoof MAC addresses.

Enable Firewall Protection

Most Wi-Fi routers come with a built-in firewall that protects your network from inbound traffic and malicious attacks. Always enable the firewall on your router for an added layer of security.

Keep Your Router's Firmware Up-to-Date

Routine updates to your router's firmware can address known bugs and vulnerabilities that can be exploited by attackers. Always keep your router's firmware up-to-date for the best possible protection.

Disable Remote Management

Remote Management provides access to a router's settings from anywhere on the internet. Unfortunately, Remote Management also provides a method for attackers to gain access to your network. Disabling Remote Management can reduce the risk of unauthorized access.

Position Your Router Securely

Keep your router away from windows, and do not place it near a location where it is visible from the outside. This will help to deter potential attackers from accessing the router.
