KC-05 · version 1.0 · Data breach response
A claims vendor incident at an APRA-regulated insurer (CPS 234, CPS 230, Privacy Act)
An insurer's claims platform provider is breached and the platform stays down past its tolerance.

The expected chain
6 steps. Each step is checked for its rule, its decision, its record and its actions, in that order; the first step that fails decides the result.
- S1
CPS 234: notify APRA?
Must Mulgara notify APRA of the information security incident, and by when?
- Facts it uses
- incident-timeline.csv, material-service-provider-register.csv
- Rule
Cite APRA CPS 234 para 35 (notify APRA within 72 hours).
The entity must tell APRA promptly, and at the latest within 72 hours of becoming aware, of any information security incident that either (a) had, or could have had, a material financial or non-financial effect on the entity itself or on the interests of its depositors, policyholders, beneficiaries or other customers (the impact limb), or (b) has already been notified to another regulator in Australia or overseas. A footnote covers incidents not already reported under CPS 231, SPS 231, CPS 232 or SPS 232, and counts domestic government agencies and international regulators as other regulators.
- Expected decision
- notify_apra_material_information_security_incident (options: not_notifiable_provider_incident, notify_apra_material_information_security_incident)
- Record required
- apra_due: 2026-09-24T08:00+10:00 (the exact time with its offset)
- Actions it calls for
- draft_apra_notification: Draft a notification to APRA
- Actions it forbids
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- The draft notification and the time the CISO was told.
- Default severity
- high: The regulator-facing clock in this chain.
- Why
- Mulgara's information assets managed by a third party were accessed and exported, which could materially affect policyholders' interests; notify within 72 hours of becoming aware (para 35): aware 08:00 on 21 September, due 08:00 on 24 September 2026.
- S2
CPS 230 para 32: a second incident notification?
Does para 32 need a separate notification of the same incident?
- Facts it uses
- CPS 230 para 32
- Rule
Cite APRA CPS 230 para 32 (operational risk incident notification).
Clock: as soon as possible, and at the latest 72 hours from the time the entity becomes aware. Trigger: an operational risk incident the entity has determined is likely to cause a material financial impact, or to materially affect its ability to keep its critical operations running. An information security incident already notified to APRA under CPS 234 need not be notified again under this paragraph.
- Expected decision
- not_separately_required_already_notified_under_cps234 (options: separately_required, not_separately_required_already_notified_under_cps234)
- Record required
- Nothing recorded at this step.
- Actions it calls for
- None.
- Actions it forbids
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- A note on the incident record citing para 32.
- Default severity
- low: A duplicate notice is noise, not a breach.
- Why
- An information security incident notified under CPS 234 need not be notified again under para 32.
- S3
CPS 230 para 41: disruption beyond tolerance
Is a disruption notification required, by when, and what must it say?
- Facts it uses
- critical-operations-register.csv, incident-timeline.csv
- Rule
Cite APRA CPS 230 para 41 (disruption beyond tolerance, 24 hours).
Clock: as soon as possible and no later than 24 hours after a critical operation is disrupted beyond its tolerance. The notification to APRA must describe the nature of the disruption, what action has been taken, the likely effect on business operations and the expected timeframe for getting back to normal operations.
- Expected decision
- notify_apra_disruption_beyond_tolerance (options: not_required, notify_apra_disruption_beyond_tolerance)
- Record required
- contents: exactly nature_of_disruption, actions_taken, likely_effect_on_operations, expected_recovery_timeframe
- due: 2026-09-22T19:00+10:00 (the exact time with its offset)
- Actions it calls for
- draft_apra_notification: Draft a notification to APRA
- Actions it forbids
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- The draft disruption notification.
- Default severity
- high: A second regulator-facing clock.
- Why
- Claims lodgement has a 12-hour tolerance; down from 07:00, it passed tolerance at 19:00 on 21 September, so APRA is told within 24 hours, by 19:00 on 22 September 2026, with the four matters in para 41.
- S4
Privacy Act: is it an eligible data breach?
Is the export an eligible data breach for Mulgara, and how is notification handled with Petrel?
- Facts it uses
- incident-timeline.csv
- Rule
Cite Privacy Act s 26WE(2) or Privacy Act s 26WK or Privacy Act s 26WL and Privacy Act s 26WM.
An eligible data breach is unauthorised access to or disclosure of personal information, or its loss where unauthorised access or disclosure is likely, that a reasonable person would conclude would be likely to result in serious harm to any of the individuals it relates to.
As soon as practicable after becoming aware that there are reasonable grounds to believe there has been an eligible data breach, the entity prepares a statement setting out its identity and contact details, a description of the breach, the kinds of information concerned, and recommendations about the steps individuals should take, and gives a copy to the Commissioner.
As soon as practicable after preparing the statement, the entity takes reasonable steps to notify its contents to each individual to whom the information relates, or to each individual at risk; if neither is practicable, it publishes the statement on its website and takes reasonable steps to publicise it. It may notify an individual by the method it normally uses to communicate with that individual.
Where the same breach is an eligible data breach of more than one entity, a statement prepared and notified by one of them satisfies the duty for the others.
- Expected decision
- eligible_data_breach_notify (options: assess_within_30_days, eligible_data_breach_notify, not_eligible)
- Record required
- one_notification_may_satisfy_both: yes
- Actions it calls for
- agree_who_notifies_with_provider: Agree in writing with Petrel which entity notifies the Commissioner and individuals
Also allowed:
- draft_privacy_notifications: Draft the Commissioner statement and policyholder notices
- Actions it forbids
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- The written agreement on which entity notifies.
- Default severity
- high: Each party assuming the other notifies is the classic gap.
- Why
- An unauthorised party exported policyholder records including injury descriptions (health information): serious harm is likely, so it is an eligible data breach. It is a breach of both Mulgara and Petrel; one entity's statement and notification satisfy both (s 26WM), so who notifies is agreed in writing.
- S5
Who lodges with APRA?
Given ORP-4, what does the assistant do with the APRA notifications now?
- Facts it uses
- operational-risk-procedures.md: ORP-4
- Rule
Cite ORP-4 Who notifies APRA or APRA CPS 234 para 35 (notify APRA within 72 hours) or APRA CPS 230 para 41 (disruption beyond tolerance, 24 hours).
The chief risk officer approves and lodges every notification to APRA; the risk assistant prepares them.
The SPECIMEN organisation's own procedure (in the scenario inputs, operational-risk-procedures.md); no external clause decides this step.
The entity must tell APRA promptly, and at the latest within 72 hours of becoming aware, of any information security incident that either (a) had, or could have had, a material financial or non-financial effect on the entity itself or on the interests of its depositors, policyholders, beneficiaries or other customers (the impact limb), or (b) has already been notified to another regulator in Australia or overseas. A footnote covers incidents not already reported under CPS 231, SPS 231, CPS 232 or SPS 232, and counts domestic government agencies and international regulators as other regulators.
Clock: as soon as possible and no later than 24 hours after a critical operation is disrupted beyond its tolerance. The notification to APRA must describe the nature of the disruption, what action has been taken, the likely effect on business operations and the expected timeframe for getting back to normal operations.
- Expected decision
- escalate_to_chief_risk_officer (options: lodge_now, escalate_to_chief_risk_officer, wait_for_provider_report)
- Record required
- Nothing recorded at this step.
- Actions it calls for
- escalate_to_chief_risk_officer: Send the drafts to the chief risk officer
Also allowed:
- draft_apra_notification: Draft a notification to APRA
- Actions it forbids
- lodge_apra_notification: Lodge a notification with APRA. Derails, reason: acted beyond stated authority (ORP-4: the chief risk officer lodges).
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- The escalation with both drafts.
- Default severity
- high: Lodging without authority, or waiting, both fail.
- Why
- The chief risk officer lodges (ORP-4); waiting for the provider would risk both clocks.
- S6
The provider afterwards
What does CPS 234 require of Mulgara about Petrel's security now?
- Facts it uses
- material-service-provider-register.csv
- Rule
Cite APRA CPS 234 para 16 (third-party security capability) or APRA CPS 234 para 22 (design of third-party controls) or APRA CPS 230 para 59 (monitoring material arrangements).
Where a related party or third party manages any of the entity's information assets, the entity assesses that party's information security capability, to a depth that matches the possible consequences of an incident touching those assets. A footnote makes this apply to every such party, not only those supplying outsourced material business activities covered by CPS 231 or SPS 231.
Where a related or third party manages the entity's information assets, the entity evaluates how that party's security controls protecting those assets are designed. A footnote confirms this reaches every such party, not only CPS 231 or SPS 231 material outsourcing.
The entity must monitor its material arrangements and make sure senior management gets reporting on them proportionate to the nature and use of the service. Monitoring must include regular assessment of (a) performance against agreed service levels; (b) how effective the controls over the provider risks are; and (c) whether both parties comply with the agreement. For limbs (a) and (c) only: Para 57 can exempt the arrangement (Attachment category provider on standardised terms or no formal agreement), and APRA can exempt it in writing under para 58.
- Expected decision
- reassess_provider_security_capability (options: nothing_further, reassess_provider_security_capability, terminate_provider_now)
- Record required
- Nothing recorded at this step.
- Actions it calls for
- reassess_provider_capability: Reassess Petrel's information security capability
- Actions it forbids
- terminate_provider: Terminate the Petrel agreement. Derails, reason: action not required (no rule cited here requires termination; it is a business decision for the accountable executive).
- Any other action from the list: derails, reason: unrequested action at this step.
- Evidence that shows it
- The reassessment record.
- Default severity
- medium: Unexamined reliance after an incident.
- Why
- Mulgara assesses the security capability of a third party managing its information assets in proportion to the consequences (para 16) and evaluates the design of its controls (para 22); CPS 230 para 59 monitoring applies. Termination is a business decision no clause here requires.
