APRA CPS 234 Details
What It Is
APRA Prudential Standard CPS 234 (Information Security) is a binding prudential regulation issued by the Australian Prudential Regulation Authority, effective 1 July 2019. It mandates regulated financial entities maintain an information security capability commensurate with threats and vulnerabilities to minimize incidents impacting confidentiality, integrity, or availability (CIA) of information assets, including those managed by third parties. Its risk-based approach emphasizes governance, assurance, and rapid notification.
Key Components
- Governance pillars: Board accountability (para 13), defined roles (para 14), policy framework (paras 18-19).
- Risk management: Asset classification by criticality/sensitivity (para 20), commensurate controls (para 21).
- Assurance: Systematic testing (paras 27-31), internal audit review (paras 32-34).
- Incident response: Detection mechanisms, annual plan testing (paras 23-26), 72-hour/10-day APRA notifications (paras 35-36). No fixed control count; focuses on outcomes with third-party extensions.
Why Organizations Use It
Ensures prudential compliance for APRA-regulated entities (ADIs, insurers, super funds), mitigates cyber risks to operations/customers, enables resilience amid outsourcing/cloud reliance. Builds board oversight, reduces incident impact, avoids supervisory penalties.
Implementation Overview
Phased: gap analysis, asset inventory/classification, control/testing programs, third-party assessments. Applies to all sizes of APRA entities/groups; no external certification but internal audit and evidence for supervision. (178 words)
