🔒️(backend) audit writes made through the Django admin

Every ModelAdmin now emits an ECS audit event when an object is created, changed or deleted, and when a bulk action runs. Actions are templated as admin.<target>.<verb>, after the model name. A signed-in account without staff access reaching the admin is recorded as a denied admin.access. The wiring is a custom AdminSite installed through AdminConfig.default_site: it mixes the auditing into every admin class at registration, including the ones Django declares, so a new ModelAdmin is covered without doing anything. It hangs off log_addition, log_change, log_deletions and get_actions, which Django calls in every path, rather than off save_model. Deletions noted by log_deletions are emitted from delete_model and delete_queryset, once their outcome is known. Changed field names are always reported; their values only for the admin_values each model is registered with, and never for anything that looks like a secret. An account acted upon is reported as user.target.

+# Audit logging
+
+La Suite Meet emits a structured **audit log**: one JSON line per notable action, saying who did what, on behalf of
+whom, on which resource, from where, and whether it succeeded.
+
+## What an event looks like
+
+Events are written on the dedicated `audit` logger, one per line and look like this::
+
+```json
+{
+  "@timestamp": "2026-09-15T08:41:12.345+00:00",
+  "ecs": {"version": "8.11.0"},
+  "log_type": "audit",
+  "service": {"name": "meet", "environment": "production"},
+  "event": {
+    "kind": "event",
+    "action": "room.create",
+    "category": ["api"],
+    "type": ["creation"],
+    "outcome": "success"
+  },
+  "trace": {"id": "6f1c0d0e2a8b4c1d9e7f0a1b2c3d4e5f"},
+  "client": {"ip": "1.2.3.4"},
+  "source": {"ip": "1.2.3.4"},
+  "http": {"request": {"method": "POST"}},
+  "url": {"path": "/external-api/v1.0/rooms/"},
+  "user": {"id": "beecd833-4be4-4675-b139-a196b07144a9", "sub": "0edebfa3-1355-4891-ae63-daf9fd37ac04", "domain": "gouv.fr"},
+  "organization": {"id": "calendar-app"},
+  "lasuite": {
+    "actor": {"type": "application"},
+    "auth": {"method": "application_jwt"},
+    "application": {"client_id": "calendar-app"},
+    "outcome": "success",
+    "target": {"type": "room", "id": "3b1d…", "slug": "daily-standup", "name": "Daily standup", "access_level": "trusted"}
+  },
+  "log": {"level": "info", "logger": "audit"}
+}
+```
+
+A refusal is recorded under the action that was attempted: the same `room.create`, with
+`"event": {"outcome": "failure", "type": ["creation", "denied"], "reason": "permission_denied"}`,
+`"lasuite": {"outcome": "denied"}`, `"http": {"response": {"status_code": 403}}` and `"error": {"message": "…"}`.
+
+## Fields
+
+Standard fields follow the [Elastic Common Schema](https://www.elastic.co/guide/en/ecs/current/index.html);
+
+| Field | Meaning |
+|---|---|
+| `@timestamp` | ISO 8601 with millisecond precision in UTC timezone` |
+| `log_type` | Always `audit` |
+| `service.name`, `service.environment` | `AUDIT_LOG_SERVICE_NAME` and current environment: the emitter, never the caller |
+| `event.action` | What was attempted, from the catalogue below |
+| `event.category`, `event.type` | ECS classification (`api`, `authentication`, `iam`... / `creation`, `change`, `access`, `denied`, `user`...) |
+| `event.outcome` | ECS `success` or `failure` |
+| `event.reason` | Why it did not succeed: `authentication_failed`, `permission_denied`, `rate_limited`, `validation_error`, `not_found`, `conflict`, `internal_error` |
+| `lasuite.outcome` | `success`, `failure` or `denied` |
+| `lasuite.actor.type` | `user`, `application`, `service`, `system` or `anonymous`, see [Actors](#actors) |
+| `lasuite.actor.name` | Name of a `service` actor: `roomkit`, `summary` |
+| `lasuite.auth.method` | `session`, `application_jwt`, `addons_jwt`, `resource_server`, `livekit_token`, `shared_secret`, `client_credentials`, `oidc`, `password`, `none`, or `unknown` for a class that is not registered. Requests served outside DRF, as the admin and logout are, report `session` when signed in |
+| `lasuite.application.client_id` | The external application acting, when there is one. Only set once its credentials are verified |
+| `user.id`, `user.sub`, `user.domain` | The account whose authority the action used, see [Actors](#actors): primary key, OIDC sub when the account has one, and email domain. The email address is never recorded |
+| `user.target.id`, `user.target.sub`, `user.target.domain` | The account an IAM action was performed on, when the target is a user. `user.*` stays the actor |
+| `organization.id` | Tenant: the application client id when present, else the user's email domain |
+| `lasuite.target` | The resource acted on: `type`, `id` and a few stable fields per type |
+| `lasuite.details` | Action-specific fields (see catalogue) |
+| `client.ip`, `source.ip` | Real client address, the one DRF's throttles identify (see `NUM_PROXIES`) |
+| `http.request.method`, `url.path` | Request as received |
+| `http.response.status_code` | Set on refusals and failures |
+| `trace.id` | Request id, also echoed as the `X-Request-ID` response header and logged by Gunicorn as `rid=`. Generated by the backend unless `REQUEST_ID_TRUST_HEADER` is set |
+| `error.message` | Human-readable reason of a failure |
+| `error.type` | Class of an unhandled exception. Its message is left out, as it may carry personal data |
+| `log.level` | `info` for success, `warning` for failures and denials, `error` for internal errors |
+
+An audited API action that raises an exception DRF does not handle is still recorded, as a `failure` with reason
+`internal_error`, status code `500` and `error.type`, before the exception propagates.
+
+### Actors
+
+`lasuite.actor.type` says who acted, and `user.*` whose authority the action used:
+
+| `lasuite.actor.type` | Who | `user.*` |
+|---|---|---|
+| `user` | A person's account acting for itself: session, OIDC or password login, add-on token, LiveKit token of a known account | That account |
+| `application` | A client application acting on behalf of a user: a Meet application through its client credentials or its delegated token, or another La Suite application through the resource server. `lasuite.application.client_id` names it | The delegating user |
+| `service` | An internal peer of the deployment acting on its own behalf with a shared secret: the LiveKit SIP bridge (`roomkit`), the summary service (`summary`). Never an account. `lasuite.actor.name` names it | Absent |
+| `system` | The backend itself, with no inbound request | Absent |
+| `anonymous` | A caller that did not authenticate, or failed to | Absent |
+
+A `client_id` in the token payload makes an application, a principal authenticated without an account a service, and
+an account a user. An event emitted with neither a request nor an actor is the system's.
+
+## Catalogue
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `application.token.issue` | An application requests a delegated token (`POST /external-api/v1.0/application/token/`), whether it obtains one or is refused: bad credentials, inactive application, invalid or unauthorized email domain, unknown user, provisioning conflict | On success: `user.*` = delegated user, `lasuite.target` = application, `lasuite.details.scopes`, `user_provisioned`, `expires_in`. On refusal: `event.reason`, `http.response.status_code`, `lasuite.details.requested_domain`. Until the credentials are verified, the submitted client id is only `lasuite.details.claimed_client_id`: it never sets `lasuite.application` or `organization` |
+| `user.provision` | An application creates a provisional user by email | `lasuite.target` = user |
+| `room.create` | A room is created through the external API, or the attempt fails | `lasuite.target` = room |
+| `room.update` | A room is updated through the external API, or the attempt fails | `lasuite.target` = room, refusals included, `lasuite.details.updated_fields`, `previous_access_level` |
+| `room.retrieve` | A room is read through the external API, or the attempt fails | `lasuite.target` = room |
+| `room.list` | Rooms are listed through the external API, or the attempt fails | `lasuite.details.total` |
+| `user.login` | A user logs in or a login attempt fails, `denied` with reason `authentication_failed` | `lasuite.auth.method` = `oidc` or `password`, or `unknown`: named after the backend on success, `lasuite.details.auth_backend`, and after the credentials submitted on failure (a password, or the nonce of the OIDC callback) |
+| `user.logout` | A user logs out | |
+| `admin.access` | A signed-in account without staff access reaches an admin page (always denied), once per refused page | `event.reason`, `http.response.status_code`: the redirect to the login page |
+| `admin.<target>.<verb>` | A write is made through the Django admin, see below | |
+
+Actions are always dotted, lower-case, with the format `<target>.<verb>`, and name what was attempted: whether it
+succeeded is told by `event.outcome`, `lasuite.outcome` and `event.reason`, never by the action.
+
+## Django admin
+
+The admin is the most sensitive surface of the product, so every write made through it emits an audit event next to
+the `LogEntry` Django writes itself. Nothing is replaced and there is no extra table: the admin history keeps working.
+
+The action is templated rather than listed: `admin.<target>.<verb>`, where `<target>` is the model name and `<verb>`
+one of:
+
+| `<verb>` | Emitted when | Notable fields |
+|---|---|---|
+| `create` | An object is added | `lasuite.details.changed_fields`, `changes` |
+| `update` | An object is changed | `lasuite.details.changed_fields`, `changes` |
+| `delete` | An object is deleted, one event per object, once the deletion has run. A deletion that raises is a `failure` with reason `internal_error`; in a bulk deletion every selected object is then reported as failed | `error.message` on failure |
+| `action` | A bulk action runs | `lasuite.details.admin_action`, `count` |
+
+So `admin.room.update`, `admin.user.delete`, `admin.recording.action`. `event.category` is `iam` for anything granting
+access to the product and `configuration` otherwise. Writes on a user or a group lead `event.type` with `user` or
+`group`, as in `["user", "change"]`.
+
+`lasuite.details.changed_fields` always carries the **names** of the fields a form changed, exactly the ones Django
+reports in its own history. `lasuite.details.changes` carries their **values**, as `{"from": ..., "to": ...}`, and only
+for the fields a model explicitly allows in the `admin_values` it is registered with. Anything that
+looks like a secret is refused there whatever the allow-list says, so a password change is reported as a change to `password` and never with its value.
+A `JSONField` on the allow-list, such as a room's `configuration`, is recorded as JSON rather than stringified, and both versions are kept
+whole.
+
+Objects edited through an **inline** emit their own event, joined to the parent's by `trace.id`: granting a role on a
+room produces both `admin.room.update` and `admin.resourceaccess.create`.
+
+What is deliberately **not** covered:
+
+- **Reads.** Opening a change list, a change form or the history page emits nothing. Django's own `LogEntry` remains
+  the record of who touched what.
+- **A custom action bypassing the ORM hooks.** An action calling `queryset.update()` or `queryset.delete()` directly
+  is reported as `admin.<target>.action` with its name and the number of objects, not one event per object.
+  `delete_selected` is the exception: Django reports its objects through `log_deletions`, so it emits one
+  `admin.<target>.delete` each and no `action` event.
+
+The wiring lives in `core/audit/admin.py`: `AuditedAdminSite` mixes the auditing into every admin class at
+registration, including those declared by Django itself, and is installed through
+`core.audit.apps.AuditedAdminConfig` in `INSTALLED_APPS`. A new `ModelAdmin` is therefore covered without doing
+anything; registering its model (see below) only adds its category and its allowed values.
+
+## Emitting events
+
+Actions are declared once, in `core/auditing.py`, as `audit.Action` constants. An action may carry its ECS category
+and types, which then apply to every event it emits:
+
+```python
+APPLICATION_TOKEN_ISSUE = audit.Action(
+    "application.token.issue",
+    category=EventCategory.AUTHENTICATION,
+    types=(EventType.START,),
+)
+ROOM_CREATE = audit.Action("room.create")
+```
+
+DRF views declare the actions they audit; everything else is derived from the response. CRUD actions are mapped in
+`audit_actions`, and an extra action names its own on its route, so that renaming its method cannot silently stop
+auditing it:
+
+```python
+from core import audit, auditing
+
+
+class RoomViewSet(audit.AuditViewMixin, viewsets.GenericViewSet):
+    audit_actions = {"create": auditing.ROOM_CREATE, "retrieve": auditing.ROOM_RETRIEVE}
+
+    def perform_create(self, serializer):
+        self.audit_target = serializer.save()
+
+    @action(detail=True, methods=["post"], audit_action=auditing.ROOM_INVITE)
+    def invite(self, request, pk=None): ...
+```
+
+- **Views are audited by `AuditViewMixin`** from DRF's `finalize_response` hook, which runs for every response,
+successful or not. The ECS category and types come from the action, else `api` and the DRF action.
+The outcome, reason and status code come from the response status: 401, 403 and 429 are `denied`, other
+errors `failure`, and a 401 is always filed under `authentication`. The target is the object `get_object()` returned,
+unless the view assigns `audit_target`. A view can also assign `audit_actor` and `audit_details`, or override
+`get_audit_fields()`.
+
+- **Anything else calls `audit.log`** with the request at hand. A `category` or `types` given here wins over the
+action's:
+
+  ```python
+  audit.log(auditing.USER_PROVISION, request=request, target=user)
+  ```
+
+- **Request fields are read from `request`**: the real client address and the path. The trace id is the request id,
+settled by `AuditLogMiddleware` right after dockerflow assigned it, and echoed in the
+`DOCKERFLOW_REQUEST_ID_HEADER_NAME` response header (`X-Request-ID` by default). The inbound id is kept only when
+`REQUEST_ID_TRUST_HEADER` is set; otherwise the backend generates one, so a client never picks it.
+
+- **Actors are derived** from `request.user`, `request.auth` and the DRF authenticator, whose class is mapped to an
+auth method by `audit.register_auth_method` (see Configuration), as described in [Actors](#actors). Without a request,
+the actor is the system. It is possible to override the actor with `actor=`, `actor_type=`, `auth_method=` and
+`client_id=`.
+
+- **Targets are described** by their model name, primary key and the `fields` their model is registered with. A model
+that is not registered is still identified. Extra keyword arguments land under `lasuite.details`.
+
+- **Emission never raises.** A broken configuration or value is reported on the application logger (and Sentry) and the
+business operation proceeds. A registered field that cannot be read is left out of the target, and the event is still
+emitted.
+
+## Configuration
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `AUDIT_LOG_LEVEL` | `INFO` | Level of the `audit` logger. |
+| `AUDIT_LOG_STREAM` | `ext://sys.stdout` | Where the handler writes |
+| `AUDIT_LOG_SERVICE_NAME` | `meet` | `service.name` |
+| `NUM_PROXIES` | `1` | DRF's number of trusted proxies appending to `X-Forwarded-For`, shared with the throttles. The client is the entry that many positions from the right; anything a client injects lands further left and is ignored. `1` matches ingress-nginx defaults; use `2` behind a load balancer that also appends |
+| `REQUEST_ID_TRUST_HEADER` | `False` | Reuse the inbound request id as `trace.id`, so the ingress, Gunicorn, application logs and audit events share one id. Only set it when the ingress overwrites the header (`proxy_set_header X-Request-ID $request_id;` on ingress-nginx, which otherwise forwards the client's one): a client could else pick the id of someone else's request |
+| `DOCKERFLOW_REQUEST_ID_HEADER_NAME` | `X-Request-ID` | Header carrying that id: read on the request only when `REQUEST_ID_TRUST_HEADER` is set, always echoed on the response |
+
+The project describes itself to the facility in code, from `core/auditing.py`. The audit app imports the `auditing`
+module of every installed app once it is ready:
+
+- `audit.register(Model, fields=..., admin_values=..., category=...)`: the `fields` describing a model as a target,
+  the `admin_values` whose before and after values may be recorded in the admin, and the `category` of its admin
+  writes. A proxy model falls back to its concrete model. Registering a model twice raises `AlreadyRegistered`.
+- `audit.register_auth_method(klass, name)`: the `lasuite.auth.method` of a DRF authentication class or of a login
+  backend. A DRF class inherits the name of its closest registered base, and DRF's own classes are built in. A login
+  backend must be registered itself, as custom backends often subclass `ModelBackend` for its permission checks
+  alone; `ModelBackend` is built in as `password`.

briquet	68632d73ab	🔒️(backend) audit writes made through the Django admin Every ModelAdmin now emits an ECS audit event when an object is created, changed or deleted, and when a bulk action runs. Actions are templated as admin.<target>.<verb>, after the model name. A signed-in account without staff access reaching the admin is recorded as a denied admin.access. The wiring is a custom AdminSite installed through AdminConfig.default_site: it mixes the auditing into every admin class at registration, including the ones Django declares, so a new ModelAdmin is covered without doing anything. It hangs off log_addition, log_change, log_deletions and get_actions, which Django calls in every path, rather than off save_model. Deletions noted by log_deletions are emitted from delete_model and delete_queryset, once their outcome is known. Changed field names are always reported; their values only for the admin_values each model is registered with, and never for anything that looks like a secret. An account acted upon is reported as user.target.	2026-10-06 12:15:10 +02:00
briquet	fc92ac353e	📝(docs) document audit logging Describe the audit event shape, the catalogue, how views and other code emit events, the environment variables configuring them, and how the project registers its actions, models and authentication classes.	2026-10-06 12:15:03 +02:00
briquet	e9f8ecc9c9	✨(backend) audit external API token and room operations Emit audit events on the most exposed authentication surface: every request to the client-credentials token endpoint, issued or refused, as application.token.issue; provisional user creation; and room create, update, retrieve and list through the delegated rooms API. Both viewsets use AuditViewMixin, so refusals are recorded under the action that was attempted, with their outcome and reason Events identify the application by client id, once its credentials are verified, and the delegated user by id, OIDC sub and email domain	2026-10-06 12:14:18 +02:00
briquet	dca78ae601	✨(backend) add structured audit logging facility Add a core.audit package emitting one ECS-shaped JSON line per security-relevant action on a dedicated "audit" logger. The actor, auth method, tenant and network fields are read from the request passed to audit.log. A person is identified by primary key, OIDC sub when the account has one and email domains. Actions are audit.Action specs carrying their ECS category and types, so a call site only names what was attempted. The project declares the rest in code, from an auditing module the audit app autodiscovers: audit.register lists the fields describing a model as a target, and audit.register_auth_method names the DRF authentication classes and the login backends. A field that cannot be read is skipped, not the event. AuditViewMixin audits every response of the CRUD actions a view maps in audit_actions, and of the extra actions naming theirs with @action(audit_action=...), from finalize_response: the outcome, reason and status come from the response, so a refusal is recorded under the action that was attempted. An exception DRF does not handle is recorded as an internal error before it propagates. The core.audit app also records Django login and logout signals.	2026-10-06 12:14:17 +02:00
