This covers tenant isolation, secrets, audit, incidents, restoration and release evidence. Passing a test or deploying a website does not certify a bank or card network. | Attribute | Module definition | | - | - | | Entry condition | Access is exercised, a security event occurs, recovery is tested or a release is proposed. | | Owned records | Security control evidence, audit event, incident, recovery exercise and release packet. | | Functional output | Verified protective controls and accountable accepted or blocked release/recovery decisions. | | Configuration | See **Required configuration** below. Parameters require institution-approved values and effective versions. | | Application entry points | Super Admin for expressly commissioned platform security/release duties; Banking Operations for institution-scoped audit/incident owners. Access is governed by the approved institution permission matrix. | ### How it differs from related modules | Related module | Boundary and handoff | | - | - | | [B02 Staff identity and access](/banking/modules/b02) | B02 operates staff identity/access records; B32 verifies their isolation, protection and audit controls. | | [B26 Risk fraud AML and compliance](/banking/modules/b26) | B26 investigates financial risk; B32 investigates platform security and operational resilience. | Read the [module comparison map](/banking/module-boundaries) for the whole platform and the [glossary](/banking/glossary) for shared terms. Planned operating duties: Security owner; Tech Ops; bank UAT owner; incident commander; auditor. Access to these duties requires the approved institution permission matrix. The bank or authorised regulated entity owns product policy and financial outcomes. Platform operators receive no automatic customer-data, fund-movement or issuer authority. ## Worked Indian example Use the four stages below to distinguish the initial facts, the action to test, confirmed completion and the alternate result. This example exercises this module’s responsibility; related modules still own the handoffs listed above. **Fictional requirements illustration, not seeded data or approved banking policy.** Reference: DR-001 / primary environment lost. | Stage | Example | | - | - | | Starting situation | The production primary becomes unavailable with several financial operations pending. | | Operator/customer actions | Contain, preserve evidence, restore/fail over under the accepted plan, query original operation outcomes and reconcile before reopening. | | Expected normal outcome | Confirmed postings survive within accepted recovery objectives; pending operations have a controlled resolution owner. | | Failure or alternate outcome | A restored screen displaying balances does not prove books, callbacks, pending instructions or audit are recovered. | No real customer, regulator approval, provider connection or bank operation is asserted. Illustrative amounts have currency INR and scale 2; actual economics/authority must be supplied by the institution. ## Module flow diagrams Read each flow from top to bottom. Rectangles are actions or recorded outcomes; diamonds are decisions; labelled arrows show the next permitted route. The denial route stops the operation. The pending/unknown route keeps the original reference for investigation instead of claiming success. Each diagram corresponds to the numbered journey below. Planned workflows are shown below. Execution depends on confirmed institution policy and interface contracts. ### Flow 1: Approve deployment architecture to monitor ```mermaid theme={null} flowchart TD START["B32-J1 request"] --> ACCESS{"Actor, institution and offering permissions"} ACCESS -->|No| DENY["Deny without exposing other data"] ACCESS -->|Yes| N0 N0["Approve deployment architecture"] N0 --> N1 N1["harden/verify controls"] N1 --> CHECK{"Incident, release or recovery authority valid"} CHECK -->|No| STOP["Stop: resolve evidence or eligibility"] CHECK -->|Yes| N2 N2["migrate/reconcile data"] N2 --> N3 N3["test restore/failover"] N3 --> N4 N4["complete UAT/certification"] N4 --> N5 N5["authorise release"] N5 --> N6 N6["monitor"] N6 --> RESULT RESULT{"Completion evidence verification"} RESULT -->|Yes| DONE["Record outcome, audit and return"] RESULT -->|Pending or unknown| HOLD["Keep original reference; reconcile status"] HOLD --> REVIEW["Authorised resolution; no blind retry"] ``` ### Flow 2: Critical incident to resume with approval ```mermaid theme={null} flowchart TD START["B32-J2 request"] --> ACCESS{"Actor, institution and offering permissions"} ACCESS -->|No| DENY["Deny without exposing other data"] ACCESS -->|Yes| N0 N0["Critical incident"] N0 --> CHECK{"State and approval eligibility"} CHECK -->|No| STOP["Stop: resolve evidence or eligibility"] CHECK -->|Yes| N1 N1["contain affected scope"] N1 --> N2 N2["preserve evidence"] N2 --> N3 N3["restore/fail over under approved plan"] N3 --> N4 N4["reconcile in-flight operations"] N4 --> N5 N5["notify"] N5 --> N6 N6["resume with approval"] N6 --> RESULT RESULT{"Outcome verification"} RESULT -->|Yes| DONE["Record outcome, audit and return"] RESULT -->|Pending or unknown| HOLD["Keep original reference; reconcile status"] HOLD --> REVIEW["Authorised resolution; no blind retry"] ``` ## Required features Planned functionality is listed below. Implementation requires confirmed field definitions, permissions, state transitions and product economics for the selected offering. | Feature | What the user or service does | Completion evidence | | - | - | - | | B32-F1: Tenant/channel isolation and least privilege | Test every read/write/file/export boundary across institution, branch and channel scopes. | Denied cross-tenant attempts reveal no protected information. | | B32-F2: Secret/key management and protected card-data boundary | Keep secrets/keys and sensitive card material inside their adopted secure boundary. | Logs, ordinary screens and backups do not expose authentication material. | | B32-F3: Immutable/redacted audit and monitored security events | Record attributable redacted audit and monitor relevant security events. | State changes and audit history agree without retaining secret payloads. | | B32-F4: Backup, restore, disaster recovery and incident exercises | Exercise backup restoration and incident/disaster procedures against adopted targets. | Recovery evidence proves restored integrity and measured loss/restoration results. | | B32-F5: Migration, certification, UAT and release evidence | Collect migration, UAT, security and required certification evidence for the release owner. | Missing acceptance remains a visible release blocker. | ## Required configuration Isolation/deployment model; encryption/keys; audit retention; RPO/RTO; capacity; release and incident authority. Store approved values in versioned, effective-dated product/programme policy. Capture the exact configuration version used by an instruction. Missing mandatory configuration blocks the dependent action; enabling a menu cannot grant legal authority. ## End-to-end journey 1 Approve deployment architecture → harden/verify controls → migrate/reconcile data → test restore/failover → complete UAT/certification → authorise release → monitor. The journey ends only when its authoritative result, customer/staff-visible result and related book or case history agree. A saved request, queue entry or HTTP acknowledgement is an intermediate state. ## End-to-end journey 2 Critical incident → contain affected scope → preserve evidence → restore/fail over under approved plan → reconcile in-flight operations → notify → resume with approval. Every transition needs an authorised actor, original version and recorded reason where required. Cancellation or client disconnection does not prove server rollback. Financial corrections retain their original reference and use linked reversal/adjustment entries rather than deleting history. ## Interfaces and data dependencies Named owners; bank-approved security/retention; PCI assessment scope; infrastructure; backup/DR; release criteria. Agree stable institution, product, party and operation references; source version; as-of time; completeness; status/finality; retry rules and correction handling. Where no financial posting occurs, record the administrative/case outcome instead of inventing a journal. All channel requests use server-verified identity and institution scope. Partner, branch and customer access is narrower than institution membership. Lists, details, search, exports, callbacks and files must enforce the same boundary. ## Current implementation and reuse **New Banking project: proposed, not built.** Current authorization, session, audit and app separation are foundations; no evidence establishes full core-bank readiness. Reviewed legacy feature boundaries: `auth`, `audit`, `admin-sessions`, `staff-sessions`, `health`. See the source inventory on the [gap page](/banking/current-system-gap). Legacy feature presence is a reuse candidate, not acceptance or deployment evidence for this module. ## Acceptance criteria and exception scenarios Explicit cases: Restore loses confirmed debit; tenant leakage; privileged compromise; split-brain posting; leaked card/PIN data. * Allowed success: confirm saved/output values, authoritative status and the exact approved actor/channel. * Denial: reject foreign institution, unauthorised branch/customer/programme and revoked or expired access without information leakage. * Reliability: prove stale-version rejection and concurrency behaviour; retryable commands apply one economic effect; unknown financial outcomes are reconciled by original reference. * Records and usability: preserve redacted audit, monetary precision and document integrity; verify keyboard/mobile, direct links, expired sessions, Back/Forward and return navigation. Internal web navigation preserves its workspace. Apply the [scenario matrix](/banking/scenario-matrix) and the [shared journey rules](/banking/journeys). Timing, amounts and regulatory applicability are institution-owned inputs, not defaults supplied by this document. ## Required implementation inputs **Status: Pending institution confirmation.** Deployment isolation, data residency, recovery targets, performance targets and institution release acceptance. Implementation dependencies and approvals are recorded in the [decision register](/banking/decisions).
