DevSecOps for Regulated Industries: What APRA, TEQSA, and Healthcare Regulators Require

Regulated industries in Australia face a particular challenge in DevSecOps: the regulatory frameworks that govern their operations were largely written before DevSecOps was an established practice, which means the specific controls required are not always clearly defined. Instead, regulators write principle-based requirements that development teams must interpret and map to specific technical controls. Getting this wrong has consequences that go beyond a failed audit.

The frameworks that most commonly intersect with application security and the software development lifecycle are APRA CPS 234 for financial services entities, TEQSA requirements for higher education providers, and the various frameworks that apply to healthcare organisations handling sensitive patient data. While the specific requirements differ, the pattern of what regulators want to see is consistent: evidence of systematic security testing, evidence that findings are tracked and remediated, and evidence that the organisation understands its information asset risks.

APRA CPS 234 and What It Means for Development Teams

CPS 234 requires APRA-regulated entities to maintain information security capability commensurate with the size and extent of threats to their information assets. For development teams, the most directly relevant requirements are around testing security controls and notifying APRA of material incidents. The testing requirement is explicit: the standard requires that information security controls be tested for effectiveness, with the frequency and rigour of testing proportional to the importance of the assets being protected.

In practice, APRA has interpreted this to expect regular security testing of customer-facing and data-handling systems, with documented testing methodology and evidence that findings are tracked to resolution. A DevSecOps programme that produces regular pen test reports, tracks findings in a formal system, and can demonstrate remediation with retest verification satisfies the spirit of the requirement. What APRA wants to avoid is the appearance of a testing programme: annual tests that produce reports that sit unread and findings that are never fixed. Evidence of an active remediation cycle, including recurrence rates in retests, is far more compelling than a large volume of test reports.

TEQSA and Application Security in Higher Education

The Tertiary Education Quality and Standards Agency regulates higher education providers against the Higher Education Standards Framework. The framework includes requirements around information management and student data security that have direct implications for application development. Universities and registered providers that develop student-facing systems, research platforms, or learning management integrations need to demonstrate that security is systematically addressed in how those systems are built and maintained.

The practical gap we see in higher education is often between the institution's policy framework, which may be well-developed, and the actual implementation in development teams that are frequently outsourced, decentralised, or operating with significant autonomy from the central IT function. A DevSecOps programme in a higher education context needs to account for this: security requirements need to be embedded in procurement and vendor management as well as internal development, and the central IT security function needs visibility across all development activity, not just what happens in-house.

Healthcare: Security in Clinical and Administrative Systems

Healthcare organisations in Australia operate under the Privacy Act and the Australian Privacy Principles, with additional guidance from the Office of the Australian Information Commissioner and sector-specific frameworks around clinical data handling. The sensitivity of the data involved means that application security failures in healthcare have consequences that extend well beyond financial penalties: breaches of clinical data affect real people in ways that can cause lasting harm.

The development and maintenance of clinical and administrative systems needs to account for the sensitivity of the data at every stage. Threat modelling for a clinical system should explicitly consider the consequences of data exposure or integrity compromise, not just the likelihood. Testing frequency should be higher for systems handling identifiable patient data than for internal administrative tools. And remediation timelines for findings in clinical systems should be treated as patient safety issues, not just IT security issues, because in some contexts they are.

What Regulators Want to See as Evidence

Across all three frameworks, the evidence that satisfies regulatory scrutiny follows a consistent pattern. Regulators want to see that you know what systems you have and what data they handle (an asset inventory), that you test those systems systematically (a testing programme with methodology documentation), that you track and remediate findings (a vulnerability management process with closure evidence), and that you review and improve your approach over time (regular programme reviews and updated testing based on new threats).

The documentation burden for regulated DevSecOps is real, but it does not require a bureaucratic approach. A well-maintained vulnerability tracking system, periodic external test reports with documented scope, retest reports showing remediation verification, and a clear mapping of those activities to the relevant regulatory requirements is often sufficient. The goal is to demonstrate systematic practice, not volume of documentation. Regulators are experienced enough to distinguish between an organisation that runs a genuine security programme and one that has generated paperwork to simulate one.

• Map your development security controls explicitly to the regulatory requirements that apply to your sector
• Maintain an inventory of information assets and their sensitivity classification
• Document your testing methodology and testing frequency rationale
• Track all findings in a formal system with assigned owners and target dates
• Keep retest reports as evidence of remediation verification, not just initial testing
• Conduct annual reviews of your DevSecOps programme against the regulatory requirements

We work with APRA-regulated entities, higher education providers, and healthcare organisations across Australia to build DevSecOps programmes that satisfy regulatory requirements and improve actual security outcomes.
