A reference guide to APRA CPS 234, Australia's information-security standard for organisations regulated by the Australian Prudential Regulation Authority. It explains how to assess security responsibilities, controls, resilience, and oversight.

In plain words
What is it for?
Use it for CPS 234 scope checks, control assessments, evidence lists, compliance reviews, and mapping security controls to the standard.
Why use it?
It helps turn a broad security requirement into evidence that shows who owns information assets, whether controls work, and whether incidents can be handled.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

au-apra-cps-234-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

APRA CPS 234 Expert

Reference-depth expertise for APRA Prudential Standard CPS 234 Information Security, represented in SCF as apac-aus-ps-cps-234-2019. This plugin bundles the SCF crosswalk (52 SCF controls to 38 framework controls) with CPS 234-specific assessment context.

Framework Identity

  • SCF framework ID: apac-aus-ps-cps-234-2019
  • Region: APAC
  • Country: AU
  • Regulator: Australian Prudential Regulation Authority (APRA)
  • Common shorthand: APRA CPS 234
  • Current assessment baseline: Prudential Standard CPS 234 Information Security, effective July 1, 2019

Framework In Plain Language

CPS 234 is APRA's prudential information security standard for regulated financial entities. It requires information security capability that is commensurate with threats, vulnerabilities, and the sensitivity and criticality of information assets. For GRC work, treat CPS 234 as an accountability and resilience framework: the assessor needs to see clear information-asset ownership, tested controls, incident response readiness, and board-level oversight of material information security risk.

Territorial Scope And Applicability

CPS 234 applies to APRA-regulated entities, including authorised deposit-taking institutions, general insurers, life insurers, private health insurers, RSE licensees, and other regulated groups within APRA's prudential perimeter. Scope analysis should identify information assets managed directly, by related parties, or by third parties, including cloud and outsourced services. Do not limit the scope to systems hosted in Australia; assets and service providers are in scope when they support APRA-regulated operations.

Mandatory Artifacts

Evidence usually centers on information security policy, asset classification and ownership records, control standards, control testing plans and results, incident response plans, board or senior management reporting, vulnerability and threat monitoring, third-party assurance, materiality criteria, and notification records. CPS 234 does not define a SOC-style report package, but APRA-regulated entities should be able to show that control design, operating effectiveness, and incident notification obligations are managed and tested.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
