In this post, I will give you the blueprint for operational resilience by navigating the Post-CPS 230 reality.
Data-breach notifications in Australia hit an all-time high in 2025, with a significant majority stemming from malicious attacks. In parallel, the Australian Prudential Regulation Authority’s (APRA) CPS 230 Operational Risk Management standard officially took effect in July 2025. The regulatory pressure on Australian technology executives shifted permanently. Boards no longer accept “we are working on it” as an answer for unpatched systems, undocumented supply chain dependencies, or vague recovery timelines.
You have to prove that critical business operations can survive systemic shocks, whether that is a cascading vendor compromise or an AI-generated ransomware campaign. Yet, balancing these strict compliance mandates against flat budgets and an exhausted service desk is incredibly difficult. Internal IT teams often spend their days putting out fires, closing tickets, and applying urgent fixes instead of mapping out long-term operational resilience.
This article breaks down how IT Directors and CIOs are restructuring their operations. We will look at moving beyond basic hygiene, managing third-party exposure, and building defensible architectures that satisfy regulators without completely burning out your internal engineering staff.

Moving past checklist compliance
For years, organizations treated security frameworks as a static compliance exercise. You implement multi-factor authentication, restrict administrative privileges, and check the boxes to claim alignment with the ASD’s Essential Eight. But the threat environment has aggressively outpaced rigid checklists. In mid-2026, the Australian Signals Directorate began evolving the Essential Eight into a broader “Essentials for enterprise IT” series, recognizing that modern technology environments require dynamic, threat-informed mitigations rather than a one-size-fits-all approach.
Checklist compliance is a dead end. Major incidents routinely expose organizations that technically aligned with basic maturity frameworks but failed to enforce those controls consistently across their legacy assets. Moving from Maturity Level One—which only stops opportunistic attacks—to Maturity Level Two requires consistent application across the entire business. To build defensible architecture, you need foundational practices that eliminate easy entry points entirely:
- Aggressive application patching: Attackers automate vulnerability scanning and exploitation. If you rely on manual, monthly update cycles, you lose. Implement automated patching for internet-facing systems to meet the strict 48-hour requirement for critical vulnerabilities.
- Identity as the perimeter: With credential theft dominating breach reports, legacy network perimeters are obsolete. Enforce conditional access policies and continuous authentication across all remote and third-party connections to limit lateral movement.
- Immutable backups: Ransomware operators actively seek out and destroy backup repositories to force extortion payments. Air-gapped or immutable backups are the only reliable way to ensure you can recover data when the primary network is compromised.
These controls form the baseline for modern infrastructure. However, maintaining them requires dedicated operational bandwidth that most internal IT teams simply lack. Offloading routine maintenance to specialized teams allows your internal staff to focus on governance.
Governing the supply chain blind spot
Your infrastructure is only as resilient as the weakest vendor in your ecosystem. CPS 230 explicitly forces regulated entities to manage the operational risks associated with their material service providers. Furthermore, if your business supplies services to an APRA-regulated entity, you are likely required to meet these stringent operational standards as well. You cannot just sign a contract and assume your software provider is handling their own environment properly.
Recent supply chain attacks prove that third-party risk is the most difficult vector to secure, as attackers use compromised suppliers to bypass your internal defenses. Relying on an annual self-assessment questionnaire during vendor onboarding is completely inadequate. When assessing your external partners and internal protocols, formalizing your approach to cyber security risk and compliance is the only way to satisfy auditors without paralyzing your operations team.
You need contractual leverage and hard technical controls to limit exposure when a supplier inevitably gets breached. This means adopting strict access principles for all external parties:
- Enforce least privilege: Limit external contractors and vendor APIs to the specific data and systems required for their immediate task. Revoke access automatically when the task or contract ends.
- Validate vendor security: Require strict evidence of MFA, regular patching, and independent security audits before integrating third-party software into your core operations.
- Map critical dependencies: Maintain a living inventory of how external applications support your critical business functions. You must have a fallback plan if a major cloud provider or software service goes offline.
Defensibility requires absolute transparency. If a vendor refuses to align with your required security baseline or balks at an audit clause, you need a roadmap to replace them.
Confronting AI-weaponized threats
Fixing basic hygiene and supply chain governance is the immediate priority, but IT leaders must also defend against a rapidly accelerating threat vector: artificial intelligence.
Threat actors are heavily weaponizing AI to scale their operations. They use language models to generate highly convincing, personalized phishing emails, clone executive voices for deepfake financial fraud, and automate the discovery of software vulnerabilities. The days of training staff to look for poor spelling in malicious emails are over. The attacks are sophisticated, context-aware, and highly targeted.
Defenders have to match this speed and scale. You cannot rely on human analysts to manually sift through thousands of event logs. Organizations are increasingly adopting their own automated threat detection and response capabilities to identify anomalous behavior in real-time before data exfiltration occurs.
Furthermore, the rise of “shadow AI” creates a massive internal risk. Employees frequently upload confidential company data, client information, or proprietary source code to public AI platforms to speed up their daily tasks. This creates severe data leakage and compliance exposures. You must implement strict AI governance frameworks, utilize data classification policies, and provide approved, secure AI platforms for your staff to use so they do not bypass IT controls.
The reality of operational resilience
Operational resilience is no longer an abstract, nice-to-have goal; it is a strict regulatory requirement and a baseline commercial necessity. The margin for error has completely evaporated. Boards are increasingly holding IT executives personally accountable for system uptime, data protection, and regulatory alignment.
By moving away from static compliance checklists, strictly governing third-party access, and preparing your architecture for AI-driven attacks, technology leaders can build environments that actually withstand disruption. Automating your routine security operations and patch management is critical—it allows your internal teams to stop chasing helpdesk tickets and start driving strategic business resilience.
Take a hard look at your current vendor contracts and service desk metrics. Do you know exactly how the next major supply chain disruption will impact your critical operations, or are you hoping for the best? Let me know in the comments how your team is handling the friction between regulatory demands and daily IT delivery.
