Plain language

WPA3-Enterprise 192-bit mode is like a high-strength lock for your wireless network. It ensures that any data sent over Wi-Fi, like emails, passwords, and client details, is protected from snooping. If this isn't set up, sensitive information could be stolen by cybercriminals, leading to financial loss or damage to your business reputation.

Why it matters

Without WPA3-Enterprise 192-bit mode, Wi‑Fi traffic can be intercepted or altered, exposing credentials and sensitive data and increasing breach risk.

Operational notes

Periodically confirm WLANs enforce WPA3‑Enterprise 192‑bit mode, using strong EAP settings and valid RADIUS certificates; remediate legacy WPA2/transition modes and non‑compliant clients.

Implementation tips

  • IT team: Ensure that all wireless network equipment supports WPA3-Enterprise 192-bit mode by checking the specifications of your current devices. Update or replace devices that do not support this standard to secure your network.
  • Managers: Work with your IT staff to review current network encryption settings. Verify that the wireless routers and access points are configured to use WPA3-Enterprise 192-bit mode and enable it if it’s not already active.
  • System owners: Collaborate with vendors to confirm that any new Wi-Fi enabled devices are compatible with WPA3-Enterprise 192-bit. This involves checking the product documentation and support forums for device compatibility information.
  • IT team: Conduct a network scan to identify any wireless devices or access points not using WPA3-Enterprise 192-bit mode. Use network monitoring tools to ensure all connections adhere to the standard for consistent security.
  • Office manager: Schedule regular training sessions for staff to educate them on the importance of network security. Explain how WPA3-Enterprise helps protect data and why ensuring its use is critical for everyone’s security and privacy.

Audit / evidence tips

  • AskThe network configuration documentation: Request a copy of the network setting files from the IT team GoodConfiguration files clearly show WPA3-Enterprise 192-bit mode is enabled on all wireless access points
  • AskA list of all network devices: Request an inventory list of all routers and access points GoodA comprehensive list showing all devices support and are configured for WPA3-Enterprise
  • AskTo see recent network audit logs: Request the latest audit logs from network monitoring activities GoodLogs indicate consistent use of WPA3-Enterprise 192-bit mode by all connected devices
  • AskA report on security training sessions: Request documentation of recent training sessions given to staff GoodCompleted training materials and attendance records showing widespread team understanding
  • AskNotes from vendor consultations: Request a summary of consultations made with vendors about device compatibility GoodDocuments include vendor confirmations and plans for future device acquisitions

Cross-framework mappings

How ISM-1332 relates to controls across ISO/IEC 27001, ISO/IEC 42001, Essential Eight, and ASD ISM.

ISO 27001

Control Notes Details
layers Partially meets (2) expand_less
Annex A 8.20 ISM-1332 requires WPA3-Enterprise 192-bit mode to protect the confidentiality and integrity of all wireless network traffic
Annex A 8.24 ISM-1332 requires a specific cryptographic protection for wireless communications by mandating WPA3-Enterprise 192-bit mode

These mappings show relationships between controls across frameworks. They do not imply full equivalence or certification.
