WiFi Security 101: Understanding the Basics
Before we dive into the world of WiFi hacking, it’s essential to understand the basics of WiFi security. WiFi networks use a type of encryption called WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), or WPA2 (Wi-Fi Protected Access 2) to secure the connection. These encryption protocols ensure that only authorized devices can connect to the network.
WEP: The Least Secure Option
WEP is the oldest and least secure encryption protocol. It uses a 64-bit or 128-bit key to encrypt the data, but it’s relatively easy to crack using freely available tools like Aircrack-ng. WEP is vulnerable to brute-force attacks, and hackers can easily gain access to the network using specialized software.
WPA: A Mid-Tier Option
WPA is a more secure option than WEP, using a 128-bit or 256-bit key to encrypt the data. WPA is more resistant to brute-force attacks, but it’s still vulnerable to certain types of attacks, such as the “evil twin” attack. WPA is still widely used, but it’s no longer considered a secure option.
WPA2: The Most Secure Option
WPA2 is the most secure encryption protocol, using a 256-bit key to encrypt the data. WPA2 is resistant to most types of attacks, including brute-force attacks and “evil twin” attacks. WPA2 is the recommended encryption protocol for most WiFi networks.
Understanding WiFi Network Types
WiFi networks can be classified into two types: open networks and closed networks.
Open Networks: WiFi Hotspots
Open networks, also known as WiFi hotspots, are publicly accessible networks that don’t require a password. These networks are often found in public places like coffee shops, airports, and libraries. Open networks are highly vulnerable to hacking and should be used with caution.
