These days keeping a private Wi-Fi more secured by having a strong password and encryption is necessary. Using a passphrase to prevent encryption is also important. Besides these, Wi-Fi can be protected by using different settings, features, and situations. Follow the points to make sure that your network is vulnerable.
Using a default SSID name for a network
Your Wi-Fi network name is called the service set identifier (SSID). It is vital to change the name of the network after buying it. Keep a strong SSID helps in securing the password. Using the default name for the network will increase the chance of cracking it. It is because the attackers use a dictionary-based SSID to break a network and using a default name makes it easier for them.
Not physically securing the APs and network hardware
One should use the best Wi-Fi security protocol as an attacker can get easy access to a wireless access point and other network components. If you have an AP sitting on the table in your office, which is unlocked, anyone as a visitor can get in your room and reset it by touching the button and gets unsecured access to the network. If you have an open network port in the waiting area or lobby, anyone can easily insert a rogue AP and get unsecured access to the network.
So it is vital to keep the main network components, including the modem, router, and switch, in a secured room or closet. Disable all the open ports in open areas.
Having a shared Wi-Fi network password
An issue with the PSK setup is that everyone uses the same Wi-Fi password to connect with the wireless network. So they cannot control individual user access. In this case, an employee, after leaving the company, can quickly get access to the network. If a hacker stole a wireless configured device with a password, he could soon get access to the network. It is vital to change the password of Wi-Fi after events like this.
Using WPS PIN authentication
A wireless router has a feature called Wi-Fi Protected Setup (WPS), and it is supposed to make securing networks easier. It poses some serious security risks like keeping the network vulnerable to the attackers. An attacker can use the pin authentication method of WPS to break the 8- digit pin and retrieve the password when the private mode is used.
