Wireless LAN Security WEP WPA IEEE 802.11i WPA 2 SSID Cloaking and MAC Filtering

Wireless LAN security is a critical concern due to the open nature of the wireless medium, which makes it easy for unauthorized users to access the network. The following are some common wireless LAN security measures:

Wired Equivalent Privacy (WEP): WEP is an older security protocol that provides encryption of wireless data. However, it has several vulnerabilities, making it easy for attackers to break the encryption.

Wi-Fi Protected Access (WPA): WPA is a more robust security protocol that improves on the weaknesses of WEP. It uses a more secure encryption method and a unique key for each wireless client to protect wireless data.

IEEE 802.11i: 802.11i is an advanced wireless security protocol that provides even stronger encryption and authentication than WPA. It uses the Advanced Encryption Standard (AES) encryption algorithm, which is considered unbreakable.

WPA2: WPA2 is the current standard for wireless LAN security. It uses the same encryption method as 802.11i and provides additional security features, such as pre-shared key (PSK) and 802.1X authentication.

SSID cloaking: SSID cloaking is a technique used to hide the wireless network’s SSID from unauthorized users. This approach is not very secure since the SSID can still be discovered through other means.

MAC filtering: MAC filtering is a method of limiting access to a wireless network by allowing only authorized devices based on their MAC addresses. However, it is not a foolproof method since MAC addresses can be easily spoofed.

In general, it is essential to implement a combination of security measures to secure a wireless LAN effectively.
