Enterprise Mode: Designed for business environments, Enterprise Mode employs Extensible Authentication Protocol (EAP) for stronger, user-specific authentication.
KRACK Vulnerability: WPA2’s major flaw is the Key Reinstallation Attack (KRACK), exposing weaknesses in the handshake process, potentially compromising data security.
Complex Setup for Enterprises: Configuring WPA2 Enterprise requires a RADIUS server, which can be complex and costly to carry out, especially for small businesses.
No Forward Secrecy: Lacking this feature means if keys are compromised, past sessions can be decrypted, posing potential risks to data confidentiality.
What is WPA3?
WPA3, a Wi-Fi security protocol launched in 2018, enhances data protection by integrating stronger encryption mechanisms. Building on the foundation of WPA2, WPA3 offers advanced features for safeguarding wireless communications.
Features of WPA3
Simultaneous Authentication of Equals (SAE): SAE replaces WPA2’s Pre-shared Key (PSK) mode, improving the handshake process by making it more secure against offline dictionary attacks. With SAE, even weak passwords receive robust protection.
Forward Secrecy: Forward Secrecy, a critical feature in WPA3, ensures that past sessions remain private even if current session keys are compromised. This enhances your data’s confidentiality by securing previous data exchanges.
Individualized Data Encryption: WPA3 Personal mode provides unique encryption for each device connecting to the network. This limits information exposure in case of network breaches and enhances overall data security.
Easy Connect (Wi-Fi Device Provisioning Protocol): This feature simplifies the process of connecting IoT devices to Wi-Fi networks through a QR code scan. It offers a user-friendly and secure method for device onboarding.
192-Bit Security Suite: Designed for enterprise environments, WPA3 includes a 192-bit cryptographic suite that meets the Commercial National Security Algorithm (CNSA) requirements, providing robust protection for sensitive data.
