The security protocols used to protect wireless networks are primarily:
- Wired Equivalent Privacy (WEP) : The original wireless security protocol, now outdated and insecure due to vulnerabilities
- Wi-Fi Protected Access (WPA) : An improvement over WEP, using TKIP encryption, but also considered insecure today
- Wi-Fi Protected Access 2 (WPA2) : The most widely used standard for many years, employing AES encryption with CCMP for strong security
- Wi-Fi Protected Access 3 (WPA3) : The latest and most secure protocol, offering stronger encryption, improved authentication (SAE), forward secrecy, and protection against attacks that affected WPA2
WPA3 is currently the recommended security protocol for wireless networks due to its enhanced protections and modern cryptographic methods. WPA2 remains common but is being phased out in favor of WPA3. WEP and WPA are obsolete and should no longer be used
