Wi-Fi is getting way more secure, thanks to WPA3

WPA3 will replace WPA2, the current network security protocol that has been in use for over a decade, according to the official press release.

WPA3, however, introduces a specification for device specific encyption, which means that even if the network can be accessed without passwords you'll be able to securely transmit data without worrying about interception by other devices.

In the intervening period, the Wi-Fi Alliance will enhance WPA2 to ensure that it provides strong security protection.

WPA2 is an industry-wide standard of safety put in almost all devices with wireless capability, but it is almost 20 years old, reports ZDNet.

OWE implements a Diffie-Hellman key exchange during network sign-on and uses the resulting secret for the 4-way 802.11 handshake rather than the shared, public Pre-Shared Key (PSK) that can be easily exploited. WPA2 (Wi-Fi Protected Access II) has been a standard security protocol and security certification program online since 2004, built to be a more secure than the original WPA and its predecessor, WEP.

Additionally, the standard will strengthen user privacy in open networks through individualized data encryption, which would prevent people from spying on network traffic on open networks. Essentially it will protect against brute-force dictionary attacks by blocking authentication after a set number of failed login attempts. IT decision-makers should consider the imminent introduction of WPA3 as an important development in an evolving security landscape.

A 192-bit security suite protects Wi-Fi networks with high security requirements and is aligned with the Commercial National Security Algorithm (CNS) Suite from the Committee on National Security Systems (CNSS). WPA2 while still useful, has several problems that WPA3 hopes to remedy, according to Github. Passwords can also be cracked offline if a cyberattacker observes an authorized user connecting to the network. The protocol is expected to emerge later this year.

The US Department of Commerce and the Department of Homeland Security also recently recognized the need to evolve network security for defending against attacks against connected medical and IoT devices.
