Headless IoT meters in city facilities cannot run 802.1X clients. What onboarding approach best improves accountability versus one shared PSK?
Select an answer to reveal the explanation.
Short Explanation
One shared PSK is a single master key under every doormat. Unique DPSK/iPSK identities give each meter its own key so you can revoke one without rekeying the whole city. Open SSIDs and finance VLAN free rides are non-starters.
Full Explanation
Devices that cannot perform 802.1X are often onboarded with unique PSKs (vendor DPSK/iPSK patterns) instead of one global Personal PSK. Unique keys improve revocation and accountability while remaining Personal-mode AKM. Open networks or placing IoT on high-trust VLANs without credentials increase risk.
