Beyond the Checkbox: Why Cybersecurity Requires Intentional, Layered Defence

This past week offers a stark lesson: cyber threats are multiplying in scale, method, and target. Treating cybersecurity as a compliance checkbox fails. What is needed instead is an intentional, layered defence that spans people, processes, and platforms.

Another Breach, Another Human Weakness Exposed

The Qantas breach should alarm every executive who thinks technical controls alone will protect their organisation. Scattered Spider, the same group that hit MGM Resorts and Caesars, didn’t use advanced malware, they used a phone. By socially engineering an offshore IT support centre, they bypassed MFA and gained access to core systems. It is a clear reminder that no toolset can prevent human error when awareness and validation processes are absent.

Cybersecurity isn’t just a technology problem. It is a human trust problem amplified by poor governance and weak third-party oversight.

The Illusion of Secure Networks

Android’s upcoming feature to warn users about fake cell towers (IMSI-catchers) highlights another misconception. Device security and encryption are essential, but they assume users know how to respond to threats. The reality is that most users will ignore warnings they don’t understand.

Enterprises need to stop outsourcing critical defence to end users and start investing in layered controls - automated detection, enterprise-managed mobile telemetry, and dynamic risk-based access policies.

The Supply Chain is Still the Weakest Link

The U.S. DOJ’s disruption of a North Korean scheme targeting American companies via remote IT contractors exposed a vulnerability few address. Over 100 firms hired North Korean IT specialists masquerading as freelance developers, handing them privileged access to sensitive systems.

This isn't a zero-day exploit. It is a failure of due diligence. Organisations chasing cost reduction in their supply chains neglected to validate who was truly behind the keyboard.

Remote work is here to stay, but remote trust cannot be assumed. Stronger access controls, continual identity verification, and geo-fencing should be mandatory—not optional.

Political Hacktivism Isn't Just a Nation-State Problem

Reports of Iranian-linked hackers preparing a smear campaign against the Trump campaign show how cyber threats are increasingly used for narrative warfare. The real damage from such operations comes not from whether the leaks are authentic, but from their ability to shape perception and sow distrust.

Organisations and media outlets need to learn that amplification without verification is part of the problem. Cybersecurity must extend into crisis communications and reputational risk management.

SMEs Under Fire

In Australia and New Zealand, SMEs are now a primary target for pro-Iran and pro-Russia hacktivists. These smaller firms are far less prepared than their enterprise counterparts and lack the scale to deploy in-house SOCs or full-time security teams.

Yet they are no less vulnerable to ransomware, DDoS, or data exfiltration. This calls for a shift in how cybersecurity solutions are designed and priced. The industry must deliver affordable managed detection, cloud-native defences, and scalable zero-trust frameworks that SMEs can adopt without enterprise overhead.

Zero Trust: Culture, Not Just Technology

Zero-trust architecture has become the go-to buzzword in vendor marketing this year, but it remains poorly implemented. Segmentation and MFA are a start, not a finish. Zero trust is about continual verification of identity, device health, and behaviour—dynamically adjusting access based on context.

If an attacker gains valid credentials, the defence should not fail at the first barrier. Layered validation and anomaly detection should kick in, providing depth rather than single-point failure.

What Needs to Change

The week’s events reinforce a simple truth: cybersecurity cannot be solved by technology alone. What is required is an intentional approach that integrates people, processes, and platforms.

• People: Regular, evolving training that reflects modern attack techniques. No more click-through compliance modules.

• Processes: Rigorous validation of third parties, privileged access management, and human‑centred threat modelling.

• Platforms: Dynamic, integrated tools that adapt to context and behaviour, not static perimeter-based defences.

Final Thoughts

Cyber threats are evolving faster than most organisations’ ability to respond. Attackers no longer rely solely on technical exploits. They manipulate people, abuse trust in third-party ecosystems, and exploit gaps between technology and process. If your defence strategy is built around ticking compliance boxes or deploying yesterday’s tools, you are already behind.

Checkbox compliance creates an illusion of safety. It satisfies auditors, but it does not stop attackers. In contrast, intentional, layered defence requires leadership commitment, ongoing vigilance, and a willingness to confront uncomfortable truths. It means acknowledging that no single control, vendor product, or policy document will keep your business secure.

Instead, defence must be built from the inside out. Start by assuming that attackers will breach your first line of defence. Plan how you will detect them before they reach your crown jewels. Harden your people, not just your platforms. Make zero trust a living practice, not a marketing slogan.

Organisations that treat cybersecurity as a continuous, evolving discipline will survive and adapt. Those that treat it as a static task to be completed once a year will become cautionary tales.

Cybersecurity is not an IT problem. It is a business survival problem. Those who understand this will be the ones left standing.
