Wi-Fi Authentication Methods
Wi-Fi authentication methods are used to verify the identity of clients before granting them access to a wireless network. These methods ensure that only authorized users can connect to a secure network. Common Wi-Fi authentication methods include Pre-Shared Key (PSK), 802.1X/EAP, and MAC Address Filtering. PSK is a simple security setup that involves entering the same security key on both the access point and the client device. The 802.1X/EAP framework provides more robust security by using an authentication server (typically RADIUS) that verifies the identity of clients using various Extensible Authentication Protocols (EAP). MAC Address Filtering allows network administrators to create a whitelist or blacklist of allowed or blocked devices based on their unique MAC addresses, although it is not a robust standalone security measure.
Guide: Wi-Fi Authentication Methods
Why it's important:
Wi-Fi Authentication Methods are a critical component in wireless network security. They control the process by which users gain access to a network. Understanding them thoroughly is necessary for protecting sensitive data from potential attackers.
What it is:
Wi-Fi Authentication Methods refer to the mechanisms or procedures that wireless networks use to authenticate users or devices - to decide whether a device is allowed to connect to a network.
How it works:
Different authentication methods include WEP, WPA, WPA2 and more. They work by securing a network through the use of encryption and protocols that verify the credentials of those trying to access the network.
