APRA Prudential Standard CPS 234 Information Security

Data privacy framework ISO 27001 GDPR APRA CPS234 commenced 1 July 2019 for APRA regulated entities as the new mandatory standards for information security.

This Prudential Standard aims to ensure that an APRA-regulated entity takes measures to be resilient against information security incidents (including cyberattacks) by maintaining an information security capability commensurate with information security vulnerabilities and threats. CPS 234 information security standards bring to the forefront the importance of having strong cybersecurity measures in place and being resilient against information security incidents and cyber-attacks in ensuring APRA entities maintain security capabilities and minimize the impact of information security incidents on Confidentiality, Integrity or Availability of Information Assets. This Includes Information Assets Managed by Related Parties or Third Parties. The Board of an APRA-regulated entity is ultimately responsible for ensuring that the entity maintains its information security.

APRA CPS 234 Information Security – Frequently Asked Questions (FAQs)

What is APRA CPS 234?

APRA CPS 234 (Prudential Standard CPS 234 – Information Security) is a mandatory cybersecurity regulation issued by the Australian Prudential Regulation Authority.
It requires regulated entities to maintain information security capabilities commensurate with their risk exposure, ensuring sensitive data and systems are protected against cyber threats.

Who must comply with CPS 234?

CPS 234 applies to all APRA-regulated entities, including:

Banks and authorised deposit-taking institutions (ADIs)
Superannuation funds
Insurance companies (life and general insurers)
Private health insurers

It also extends to third-party service providers that manage or process critical information assets on behalf of regulated entities.

What are the key objectives of CPS 234?

The standard is designed to ensure:

Information security risks are identified, assessed, and managed effectively
Security controls are proportionate to the criticality and sensitivity of assets
Boards and senior management maintain clear accountability for cybersecurity
Incidents are detected and reported in a timely manner

CPS 234 shifts cybersecurity from an IT issue to a core governance and risk management responsibility.

What are the core requirements of CPS 234?

Key requirements include:

Information Security Capability – Adequate controls and skilled resources
Policy Framework – Board-approved information security policy
Asset Classification – Identification and classification of critical assets
Testing & Assurance – Regular control effectiveness testing (e.g., penetration testing)
Incident Notification – Mandatory reporting of material incidents to APRA within 72 hours
Third-Party Risk Management – Oversight of service providers

What is the role of the board under CPS 234?

Boards are explicitly accountable for:

Approving the information security policy
Ensuring adequate resources and capability
Overseeing cyber risk management frameworks
Receiving regular reporting on control effectiveness

This makes CPS 234 a board-level compliance obligation, not just an operational requirement.

What are “information assets” under CPS 234?

Information assets include:

Customer data and financial records
Systems and applications
Infrastructure (cloud, networks, endpoints)
Third-party hosted environments

Entities must classify these assets based on criticality and sensitivity and apply controls accordingly.

How often must organisations test their security controls?

CPS 234 requires systematic testing of controls, including:

Regular vulnerability assessments
Penetration testing (internal and external)
Control assurance reviews

Testing frequency must align with the threat environment and asset criticality, not a fixed annual schedule.

What are the incident reporting requirements under CPS 234?

Organisations must notify APRA:

Within 72 hours of becoming aware of a material information security incident
When a control weakness is identified that could materially impact operations

This requires organisations to have robust detection, response, and escalation processes in place.

How does CPS 234 impact third-party and outsourcing arrangements?

CPS 234 places strong emphasis on third-party risk management, requiring organisations to:

Assess the security posture of vendors and service providers
Ensure contractual obligations include security controls
Monitor third-party compliance on an ongoing basis

This is particularly critical for cloud providers and managed service partners.

What are the consequences of non-compliance with CPS 234?

Failure to comply can result in:
Regulatory enforcement actions by the Australian Prudential Regulation Authority

Increased supervisory scrutiny and audits
Financial penalties and remediation costs
Reputational damage and loss of stakeholder trust

For boards, non-compliance represents a direct breach of fiduciary and governance responsibilities.

How does CPS 234 align with other frameworks like ISO 27001 and NIST?

CPS 234 is not a standalone framework—it aligns with:

ISO/IEC 27001 (ISMS implementation)
NIST Cybersecurity Framework (risk-based maturity)
PCI DSS (where payment data is involved)

Organisations often leverage these frameworks to demonstrate CPS 234 compliance in a structured way.
