The Australian Government is taking a significant step to improve the cyber security of the digital products Australians use every day.

From 4 March 2026, the Cyber Security (Security Standards for Smart Devices) Rules 2025 will come into effect, following a 12‑month transition period. These Rules introduce mandatory cyber security standards for most consumer smart devices acquired in Australia, moving the country away from voluntary guidance and toward enforceable baseline protections.

This initiative is a key action under the 2023–2030 Australian Cyber Security Strategy and is designed to address long‑standing weaknesses in everyday internet‑connected devices such as smart cameras, TVs, speakers, appliances, and other home IoT products. The intent is simple: reduce avoidable cyber risk by ensuring smart devices are designed and sold with security built in, rather than added (or ignored) later.

At a high level, the Rules require manufacturers and suppliers to:

• Eliminate universal default passwords
• Provide a clear process for reporting security vulnerabilities
• Be transparent about how long devices will receive security updates

For consumers, this is a very positive development. For businesses, it’s an important piece of a much larger security picture.

Why this is a welcome move, but not the whole answer

Poorly secured smart devices have long been an easy target for cybercriminals. Many were designed for convenience and cost, not long‑term security. In practice, this has meant:

• Devices shipped with weak or shared passwords
• Limited or non‑existent security updates
• Little visibility into vulnerabilities once products were in the market

By setting mandatory minimum standards, the new Rules raise the baseline for device security across Australia. This will reduce large‑scale, opportunistic attacks and help prevent insecure devices from being quietly deployed into homes and workplaces.

As Chris Cox, Head of Infrastructure and Security Solutions at Diamond IT, explains:

 “It is important to understand what these standards do and don’t cover. The Rules apply to consumer smart devices. They do not apply to business endpoints such as laptops, desktops, tablets, or mobile phones, nor do they address how devices are connected, managed, or monitored once they’re inside a network”.

That’s where business responsibility begins.

The missing link: how smart devices can expose business systems

“One of the most misunderstood cyber risks is how a seemingly harmless smart device can be used as a pathway into business systems” Chris adds.

In many environments, smart devices share networks with business laptops, printers, or other corporate assets. In remote and hybrid work scenarios, this is even more common, a work laptop often sits on the same home network as smart TVs, cameras, or voice assistants.

If a smart device is compromised, attackers may not stop there. Instead, they can:

• Use the device as a foothold inside the network
• Scan for other connected systems
• Attempt to access business devices or capture credentials
• Move laterally toward higher‑value targets

This type of sideways spread, often called lateral movement, is a common feature of modern cyber incidents. While the new smart device standards reduce the likelihood of easy compromise, they cannot prevent attackers from exploiting weak network design or unmanaged business endpoints.

In other words, securing smart devices helps, but businesses still need to protect the devices that matter most.

What this means for business devices, especially mobile

Business‑critical devices sit outside the scope of the smart device Rules, particularly:

• Mobile phones
• Tablets
• Laptops used by remote and hybrid workers

These devices:

• Access corporate email, files, and cloud applications
• Store sensitive business data
• Move between trusted and untrusted networks every day

Unlike consumer smart devices, their security depends heavily on how they are configured, managed, and monitored by the organisation.

This is where Mobile Device Management (MDM) and Mobile Application Management (MAM) play a crucial role.

An effective strategy to secure mobile devices, particularly BYOD, allows organisations to:

• Enforce strong security policies (PINs, biometrics, encryption)
• Control access to corporate data and applications
• Push security updates and configurations centrally
• Remotely lock or wipe devices if they are lost, stolen, or compromised
• Separate personal and business data on BYOD devices

In the context of the new smart device standards, MDM and MAM helps close the gap between better‑secured consumer technology and properly protected business endpoints.

Turning regulation into real‑world protection

Australia’s smart device security standards are a strong and necessary step forward. They reduce systemic risk, improve consumer protection, and help remove some of the weakest links from everyday digital environments.

But regulation alone doesn’t secure a business.

Security today is about layers, not single solutions. The new Rules strengthen one layer — device manufacturing. Businesses must strengthen the layers they control.

In the next section, we’ll look at practical recommendations businesses can apply now to reduce risk across smart devices, mobile endpoints, and modern work environments.

Practical steps businesses can take now…

To translate regulation into meaningful risk reduction, organisations should focus on the areas they directly control.

1. Segment smart devices from business systems
   Smart devices should not sit on the same network as business‑critical endpoints. Network segmentation and access controls help contain risk if a device is compromised.
2. Actively manage mobile and endpoint devices
   Laptops, tablets, and phones should be enrolled in an MDM / MAM solution to ensure consistent security policies, visibility, and rapid response if something goes wrong.
3. Treat remote and hybrid work as part of the perimeter
   Home networks are now an extension of the corporate environment. Security controls must assume business devices will operate alongside consumer technology.
4. Reduce implicit trust between devices
   Modern security assumes breach. Limiting how devices communicate with each other reduces the impact of any single compromise.
5. Keep security practical and proportionate
   The goal isn’t to eliminate smart devices, it’s to deploy them safely, with the right controls around what matters most.

Australia’s new smart device security standards are a positive shift in the right direction. Combined with strong device management, network design, and modern security practices, they can help organisations reduce risk without sacrificing flexibility or productivity.
