12.1 / SECURITY

Risk-informed security.

How identity, data, development, operations and response inform engineering decisions — with depth proportional to each system's context.

SECURITY MODEL

Security is a distributed responsibility.

No single control resolves every risk. The model informs layered decisions — from product definition to operations — according to the data, integrations, people and criticality of each context.

  1. 01 / PRODUCT

    Context and boundaries.

    Goals, data, flows and responsibilities help define where additional attention is needed.

  2. 02 / ARCHITECTURE

    Explicit boundaries.

    Components, integrations and access paths are considered to make responsibilities and exposure understandable.

  3. 03 / DELIVERY

    Examinable changes.

    Review, validation and environment separation can be applied according to the agreed process and scope.

  4. 04 / OPERATIONS

    Signals to act.

    Observation, response and learning connect system behavior to evolution decisions.

IDENTITY, DATA AND DEVELOPMENT

Controls connected to engineering work.

The selection and depth of controls depend on risk, architecture and the responsibilities defined for each system.

01Identity and access
Access should follow function, need and context. Permissions, service accounts and administrative paths are treated as architecture and operations decisions.
02Data and secrets
Data, credentials and keys require treatment compatible with the purpose and exposure of each flow. Storage and access details depend on the contracted technical scope.
03Secure development
Reviews, validation and architecture choices seek to reduce foreseeable errors before a change reaches operations.
04Dependencies
Libraries, services and external components are part of the system's surface. Their adoption and update need to consider origin, maintenance and impact.

CHANGE AND CONTINUITY

Operations begin before deployment.

Environments, changes, operational signals and continuity plans are discussed as parts of the same system — with depth proportional to project context.

ENVIRONMENTS
Separation between development, validation and operational contexts is defined according to architecture, risk and delivery process.
CHANGES
Review, approval and traceability can be part of a change flow when the context needs greater control.
OBSERVABILITY
Logs, signals and telemetry are considered to understand behavior and support investigation, without turning visibility into an availability promise.
BACKUPS AND RECOVERY
Copy, recovery and continuity strategies depend on data, infrastructure, responsibilities and objectives agreed for each operation.

VULNERABILITIES AND INCIDENTS

Responding well requires context, coordination and learning.

The process organizes how a security issue can be received, understood and taken to the responsible people. The response model and operational responsibilities vary according to the contract, system and applicable scope.

  1. 01

    Receive

    Record the report with enough context to begin an assessment.

  2. 02

    Assess

    Understand the affected system, observed impact, exposure and dependencies.

  3. 03

    Coordinate

    Define owners, communication and next steps compatible with the context.

  4. 04

    Correct and learn

    Turn analysis into product, engineering or operations adjustments when applicable.

DEPENDENCIES AND THIRD PARTIES

A system boundary includes what it integrates.

Infrastructure services, APIs, libraries and other providers can be part of a delivery. We assess dependencies relevant to a project's design and responsibilities, without extending this page into guarantees about third-party controls.

Supplier, integration and responsibility information is handled according to scope, contract and authorization to disclose it.

RESPONSIBLE REPORTING

Found a potential vulnerability?

Use the responsible reporting flow to send the technical context required. Do not include sensitive information in the institutional contact channel, access third-party data or interrupt services during research.
