APRA CPS 234
How Scrutex Supports APRA Prudential Standard CPS 234 Compliance
Executive Summary
APRA CPS 234 requires APRA-regulated entities to maintain an information security capability commensurate with the size and extent of threats to their information assets. The standard places accountability on the Board and includes mandatory 72-hour breach notification to APRA. Scrutex supports CPS 234 compliance across asset identification, vulnerability testing, third-party oversight, data exposure monitoring, brand protection, threat intelligence, and Board-level reporting.
About APRA CPS 234
CPS 234 requires APRA-regulated entities to be resilient against information security incidents. The standard places accountability on the Board, requires testing of security controls, mandates third-party security management, and introduces a 72-hour notification requirement for material incidents and 10 business days for material control weaknesses. APRA's supervisory approach is outcomes-focused. Entities must demonstrate that controls are effective, not merely that they exist. APRA has publicly noted its expectation that entities maintain comprehensive asset inventories, robust testing programmes, and meaningful third-party oversight.
Geographic and Sector Applicability
CPS 234 applies to all APRA-regulated entities: authorised deposit-taking institutions (banks, building societies, credit unions), general and life insurers, private health insurers, and superannuation fund licensees. The standard extends to information assets managed by third parties. Any offshore service provider handling information assets on behalf of an APRA-regulated entity is indirectly within scope.
Who Should Care
Board
CPS 234 explicitly requires the Board to ensure the entity maintains an information security capability commensurate with threats. Board members must receive regular reporting on security posture.
CISO
Owns the information security programme, including asset classification, control implementation, testing, and APRA notification.
Chief Risk Officer
Information security risk is a prudential risk. The CRO must integrate information security into the entity's broader risk management framework.
Procurement and Vendor Management
Paragraphs 24-28 create specific obligations for managing third-party information security, requiring active assessment and ongoing assurance.
Key Risks of Non-Compliance
Formal supervisory actions, including enforceable undertakings and directions to remediate specific control weaknesses.
Increased capital requirements or operational restrictions imposed by APRA as prudential measures.
Public enforcement actions that damage market confidence and brand reputation in a concentrated banking market.
72-hour notification obligation for material incidents creates time pressure and regulatory scrutiny.
10-business-day notification for material control weaknesses means that identified gaps cannot remain unreported.
Common Compliance Gaps
Incomplete Information Asset Registers
Paragraph 15 requires identification and classification of information assets. APRA has noted that many entities have incomplete inventories, particularly for cloud-hosted services, third-party managed systems, and externally accessible applications.
Insufficient Third-Party Assurance
Paragraphs 24-28 require active assessment of third-party security capability. Many entities rely on vendor self-attestation rather than independent verification, which APRA considers insufficient.
Infrequent Control Testing
Paragraph 23 requires systematic testing of security controls. Many entities test annually at most, leaving gaps between test cycles where new vulnerabilities can emerge.
Delayed Incident Detection
The 72-hour notification window requires rapid detection capability. Entities relying solely on internal monitoring may not detect breaches involving external credential compromise or data exposure until significant harm has occurred.
How Scrutex Supports APRA CPS 234 Compliance
Scrutex capabilities mapped to APRA CPS 234 requirements.
CPS 234 requires entities to identify and classify information assets (Paragraph 15) and implement controls commensurate with threats (Paragraph 18). Scrutex continuously discovers and monitors externally visible information assets, including those not captured in formal registers. Paragraph 23 requires systematic testing of security controls. Scrutex provides continuous external vulnerability assessment between formal test cycles, identifying new vulnerabilities as they emerge rather than waiting for the next scheduled review.
