Wi-Fi uses enterprise authentication and strong encryption — not a shared password.
What it actually means
Authorized isn't enough; the wireless itself must be locked down with real authentication and strong encryption — WPA2/WPA3-Enterprise with 802.1X, not a pre-shared key taped to the wall.
Pass or fail — an assessor needs a "yes" to each
- Wireless uses WPA2/WPA3-Enterprise (802.1X), not a shared PSK.
- Encryption is current and strong.
- Each user/device authenticates individually.
What to have ready
- Wireless security configuration (WPA2/3-Enterprise, 802.1X)
- RADIUS/identity integration
- Disabled weak protocols
Where teams trip up
- A single shared Wi-Fi password for everyone
- WEP/WPA-Personal on CUI networks
- Guest and CUI wireless not separated
Not Applicable only if no wireless is used for CUI (document it).
