A legacy SCADA SSID in a utilities plant still permits WEP and TKIP. What threat-driven action is required?
Select an answer to reveal the explanation.
Short Explanation
WEP and TKIP are museum pieces that still open doors for attackers. Tagging a VLAN doesn’t magically encrypt broken ciphers—schedule the move to modern WPA2/WPA3 suites and shut the old ones off. “We’ll get to it someday” is how plants inherit yesterday’s breaches.
Full Explanation
Deprecated 802.11 security suites (WEP, TKIP/RC4-era constructs) are cryptographically broken or obsolete and must be eliminated. Migration to robust RSN suites (CCMP/GCMP under WPA2/WPA3 as applicable) is urgent, including compensating network isolation only as a temporary bridge—not a permanent excuse. VLAN tagging or time-of-day WEP does not remediate weak link-layer crypto.
