WEP

WEP (Wireless Equivalent Privacy) is an outdated Wi‑Fi encryption standard originally intended to provide comparable protection to wired networks. From a networking standpoint it uses the RC4 stream cipher and a small 24-bit initialization vector (IV), which leads to IV reuse, weak key scheduling and practical attacks that allow key recovery. For Audio/Video, Maker and Web contexts this matters because WEP does not provide reliable confidentiality, integrity, or strong authentication: audio and video streams can be eavesdropped or tampered with, IoT/maker hardware can be compromised, and web sessions or credentials transmitted over a WEP network are vulnerable to sniffing and man-in-the-middle attacks. WEP has been superseded by WPA/WPA2/WPA3 because of these fundamental flaws, and its use is strongly discouraged.

Imagine you set up a live-streaming IP camera (Audio/Video) on a local Wi‑Fi network using WEP: an attacker can capture traffic and view or record the video stream because WEP is trivial to crack. As a maker, you connect an ESP8266/ESP32 module with WEP for a prototype sensor or actuator; an adversary can recover the WEP key, take control of the device, or pivot into the rest of your network. As a web developer, you test a web application on that same WEP network — credentials, session cookies or API calls can be read and altered by an attacker, leading to data leaks and unreliable testing. Practical mitigations include moving to WPA2/WPA3 immediately, using end-to-end encryption such as HTTPS or a VPN, and ensuring firmware and network configurations are current for all audio/video gear, maker hardware and web servers.
