Understanding Wi-Fi Network Security
Before we dive into the reasons behind an unsecured Wi-Fi network, it’s essential to understand the basics of Wi-Fi security. Wi-Fi networks use encryption protocols to secure data transmission between devices. The most common encryption protocols are:
WEP (Wired Equivalent Privacy)
WEP is an outdated encryption protocol that was introduced in the late 1990s. Although it was once considered secure, WEP has several vulnerabilities that make it easily hackable. If your router is still using WEP, it’s highly recommended to switch to a more secure protocol.
WPA (Wi-Fi Protected Access)
WPA is a more secure encryption protocol than WEP, but it’s still vulnerable to hacking. WPA uses a pre-shared key (PSK) or a passphrase to authenticate devices.
WPA2 (Wi-Fi Protected Access 2)
WPA2 is the most secure encryption protocol currently available. It uses the Advanced Encryption Standard (AES) to encrypt data and is considered unbreakable. However, WPA2 has its own set of vulnerabilities, such as the KRACK attack.
WPA3 (Wi-Fi Protected Access 3)
WPA3 is the latest encryption protocol, introduced in 2018. It provides enhanced security features, such as individualized data encryption and protection against brute-force attacks.
