During a county WLAN architecture review, RC4 appears in a cipher-suite discussion for air encryption. How should RC4 be classified for Wi-Fi security?
Select an answer to reveal the explanation.
Short Explanation
RC4 is the old stream-cipher workhorse that rode along with WEP and TKIP—and that whole neighborhood is condemned. Do not plan new county Wi-Fi security around it; AES-based suites are the grown-up answer.
Full Explanation
RC4 underpinned WEP and TKIP constructions and is treated as deprecated for Wi-Fi security purposes under CWSP deprecated-solutions objectives. Modern WLAN designs use AES-based CCMP/GCMP (and related modes), not RC4. Claiming RC4 is required for WPA3 192-bit mode or that it replaced AES is incorrect.
