Wired Equivalent Privacy (WEP)
Also called: WEP
Course: AP® Cybersecurity Shows up in: Unit 3: Securing Networks
An early wireless encryption protocol with known vulnerabilities; it is insecure and should never be used.
Appears in the course and exam description (CED): 3.2.B.3
Why it matters in Unit 3
Strong wireless encryption keeps captured frames unreadable. WEP does not, so a network still using it needs to change to Wi-Fi Protected Access 3 (WPA3).
Example
A scan shows an old access point offering WEP: flag it as a vulnerability in the network risk assessment.

Security professionals worldwide use these: the NIST glossary (the U.S. government's official security dictionary), MITRE ATT&CK (real attacker techniques), MITRE CWE (software weaknesses) and the internet's own standards (RFCs). They go beyond the AP® course, so use the definition above for the exam.
