Compliance reference · APRA CPS 234
APRA CPS 234 is the foundational information security standard for every APRA-regulated entity. It is the standard every other APRA prudential standard refers to when it talks about security. Get this one right and the rest of the stack gets easier.
What it actually requires
CPS 234 is short by APRA standards but unambiguous on ownership. Information security is a Board obligation. The four pillars below are how the Board demonstrates the obligation is being met.
Information security is a Board accountability. Roles for the Board, senior management, and governing bodies must be clearly defined and documented. The standard does not allow ownership to drift into "shared responsibility" with no name attached.
Maintain capability commensurate with the size and extent of threats to information assets. Capability is assessed against the actual threat landscape — not the threat landscape from when the policy was last reviewed.
Detect, respond to, recover from, and learn from information security incidents. Material incidents must be notified to APRA promptly and within the required reporting window. Capability to inform members and counterparties is part of the obligation.
Service providers and other third parties that manage information assets must meet equivalent standards. Due diligence at onboarding, ongoing oversight, and exit planning are all in scope. Concentration and fourth-party exposure require explicit treatment.
Four problems that show up in nearly every CPS 234 conversation.
The information security capability assessment was thorough at the time. Two years on, the threat landscape has shifted, the architecture has changed, and the assessment reads as a historical document rather than a live picture.
Your assessment lags your risk by 18 months.
When a real incident hits, the notification window arrives faster than the internal investigation does. The first hour is spent on internal escalation and the second hour realising the regulator clock has been running the whole time.
You miss the window, then explain why.
The information security register of service providers was built during readiness. New SaaS contracts are signed by procurement without security review. Six months later the register and reality have parted ways.
Your register cannot be defended in tripartite review.
Cloud AI tools cannot demonstrate where data goes, how it is segregated, or how to delete it on demand. Security review says no. The compliance team becomes the team blocking the productivity wins everyone else can see.
You cannot deploy the AI you can already justify.
How BackPro maps to CPS 234
Each row maps a CPS 234 obligation to the part of BackPro that does the work. The platform itself is built to be deployable inside a CPS 234-aligned tenant — the obligations and the platform pull in the same direction.
CPS 234 obligation
BackPro deployments come with documented role-mapping for Board, senior management, and operational owners — version-controlled and signed in the audit chain. Approval workflows enforce the documented matrix; nothing material happens without the documented owner signing it.
CPS 234 obligation
Continuous capability monitoring — the Control Monitor agent watches for failing controls, stale evidence, and policy drift. Evidence freshness is surfaced as a finding, not buried in a spreadsheet. The capability picture updates as the landscape shifts.
CPS 234 obligation
Incident playbooks live in the platform with a tamper-evident chain of custody on each step. The audit log signs every action with HMAC-SHA256 and chains it to the previous entry, so the regulator notification carries the evidence trail without a separate evidence-pull.
CPS 234 obligation
The Vendor Risk agent watches contract expiries, due-diligence cadence, and concentration exposure across material service providers. New SaaS engagements surface as findings until the security review is complete and signed.
CPS 234 obligation
BackPro itself is designed to be deployable inside an APRA-aligned tenant. Production infrastructure-as-code ships for Azure, AWS, and GCP with encryption at rest and in transit, role-based access control, audit logging on by default, and tenant isolation. SOC 2 Type II and ISO/IEC 27001 readiness underway.
CPS 234 lands across three desks more than any other.
