APRA CPS 234 vs ASD Essential 8: A Comparison

In the ever-evolving cybersecurity landscape, compliance with industry standards is not just a benchmark but a necessity. IT professionals, compliance officers, CISOs, and business owners must navigate the complexities of regulations such as APRA CPS 234 and the ASD Essential 8. While both frameworks serve as pillars of cyber defence, understanding their nuances is key to robust compliance and cybersecurity strategy.

Understanding APRA CPS 234

The Australian Prudential Regulation Authority (APRA) CPS 234 is a mandate that aims to fortify the cyber resilience of the financial industry. APRA CPS 234 outlines clear requirements for regulated entities to protect themselves against cyber threats and minimise potential losses.

Key requirements include defining cybersecurity roles and responsibilities, conducting regular testing, notifying APRA of significant breaches, and more. The intricacies of these obligations are crucial for IT professionals, compliance officers, and CISO’s meticulous adherence to safeguard their organisations’ integrity.

Understanding ASD Essential 8

On the other hand, the Australian Signals Directorate (ASD) Essential 8 is a set of strategies designed to fortify systems against a multitude of cyber attacks. This strategic framework emphasises proactive security measures rather than prescriptive compliance procedures, making it pertinent for those who aspire toward a resilient cyber posture.

For your IT team and security leaders, the ASD Essential 8 framework highlights the proactive steps needed to prevent and mitigate cybersecurity incidents effectively. It covers aspects like application whitelisting, patching systems, restricting administrative privileges, and more.

Comparison of APRA CPS 234 and ASD Essential 8

When comparing APRA CPS 234 and ASD Essential 8, it is evident that both share a common goal of improving cybersecurity practices. However, the paths they take diverge in terms of their scope and focus. 

APRA’s CPS 234 largely revolves around the financial sector and its need for accountability and risk management, while the ASD Essential 8 is more broadly aimed at providing general best practices that any organisation can apply to bolster security.

Benefits of Compliance

Compliance with either, or both, of these frameworks isn’t just about checking off a list – it’s about establishing a comprehensive cybersecurity culture. By aligning with APRA CPS 234 and ASD Essential 8, organisations reinforce their security architecture, ultimately contributing to their operational resilience and safeguarding their reputation.

Challenges and Considerations

Implementing and maintaining compliance with these frameworks is not without its challenges. Organisational changes may be required, which could pose integration issues with existing security measures. For business owners, the investment in resources and continuous improvement in security practices must be balanced against other business demands.


The side-by-side evaluation of APRA CPS 234 and the ASD Essential 8 reveals that while their approach and emphases might differ, the core principle is the same: rigorous cybersecurity measures are indispensable. As the digital thread weaves tighter into the fabric of everyday business, the clarity and insight IT and security professionals gain into these frameworks are paramount.
