WPA2 (Wi-Fi Protected Access 2), introduced in 2004, became the default standard for securing wireless networks. It utilizes AES (Advanced Encryption Standard) encryption, ensuring reliable protection against unauthorized access.
One of WPA2’s greatest strengths is its compatibility. Almost every Wi-Fi-enabled device supports WPA2, making it widely used across homes and businesses. However, despite its reliability, WPA2 is not without flaws. Vulnerabilities such as the KRACK (Key Reinstallation Attack) exploit and susceptibility to brute-force password attacks have shown its limitations in an era of evolving cyber threats.
