CTS 343: Exploring Wi-Fi Security and Encryption

Clear To Send: Wireless Network Engineering

In this episode of Clear To Send, François and Rowell dive into the world of Wi-Fi security and encryption as part of our “Back to Basics” series. We break down the evolution of Wi-Fi security, from the outdated and unsafe methods to the current gold standards.

Here’s what we cover:

• A brief history of Wi-Fi security, including the now-obsolete WEP and WPA (TKIP) methods
• Current security techniques: WPA2 (PSK and Enterprise) and WPA3 (SAE and Enterprise)
• Guest access options: Open Authentication and Enhanced Open (OWE)
• The importance of staying updated with the latest security protocols

We also discuss why older security methods are no longer safe and why it’s crucial for both home users and enterprises to adopt the latest standards. Whether you’re a network admin or just curious about your home Wi-Fi security, this episode has something for everyone.
