A municipal IoT SSID shares one WPA2-PSK across dozens of sensors and rotates that passphrase quarterly. What primary security benefit does regular rotation provide?
Select an answer to reveal the explanation.
Short Explanation
Shared IoT keys travel—staff write them down, vendors reuse them, assessments recover them. Spinning the passphrase on a schedule shrinks how long a leak stays useful. It is hygiene, not a free upgrade to Enterprise or WPA3.
Full Explanation
Shared PSKs create a broad blast radius when disclosed. Scheduled rotation limits how long a compromised or weak passphrase remains valid across the device fleet. Rotation alone does not convert the network to 802.1X, does not make handshake capture impossible, and does not magically enable WPA3-SAE on incompatible radios.
