ASD ISM 1332 Ensure wireless traffic is secure with WPA3-enterprise
What it says
WPA3-Enterprise 192-bit mode is used to protect the confidentiality and integrity of all wireless network traffic.
Quoted as published. Everything else on this page is written by Control Stack.
What it means
In plain EnglishUse WPA3-Enterprise 192-bit mode to secure information transferred over wireless networks.
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.
How to implement
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.
Keep it running
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.

ISO/IEC 27001: 2 mappings
This control partially meets A.8.20.
ISM-1332 requires WPA3-Enterprise 192-bit mode to protect the confidentiality and integrity of all wireless network traffic. Annex A 8.20 requires networks and network devices to be secured, managed and controlled, which includes securing wireless LANs and their access points. ISM-1332 is a specific mandated technical implementation for one network use-case (wireless), while Annex A 8.20 is broader and technology-agnostic across all networks and devices.
This control partially meets A.8.24.
ISM-1332 requires a specific cryptographic protection for wireless communications by mandating WPA3-Enterprise 192-bit mode. Annex A 8.24 requires rules for effective use of cryptography and cryptographic key management across the organisation, which would include selecting and managing cryptography for wireless protections. ISM-1332 is a specific prescriptive requirement for one channel (wireless traffic), whereas Annex A 8.24 is broader and covers governance, selection, and key lifecycle management across many use-cases.
