This works well for high-confidence detectors like FastNetMon in ban mode, but creates two problems: + +1. **Low-confidence signals go to waste.** A telemetry-based alert at 0.5 confidence is too weak to act on alone, even though it carries useful information. If two independent sources both flag the same victim and vector, the combined evidence is much stronger than either signal alone. + +2. **No corroboration path.** Operators who integrate multiple detection sources (NetFlow analyzers, Alertmanager rules, FastNetMon, manual reports) have no way to require agreement between sources before triggering a mitigation. They either set low thresholds (false positives) or high thresholds (missed attacks). + +The correlation engine addresses this by grouping related signals within a configurable time window and computing a weighted confidence score across sources. Corroboration — requiring a minimum number of distinct sources — becomes an optional, per-playbook policy lever. + +### Alternatives Considered + +1. **Client-side aggregation.** Have detectors pre-aggregate before calling the API. Rejected because it pushes complexity to every integration and prevents cross-source corroboration. + +2. **Event deduplication only.** Extend the existing `EventCorrelator` (scope-matching by ports) to track sources. Rejected because scope-matching serves a different purpose (extending TTL on same-scope mitigations) and conflating the two concepts makes both harder to reason about. + +3. **External stream processor (Kafka/Flink).** Powerful but introduces significant operational complexity for what is fundamentally a small-cardinality grouping problem (unique victim_ip × vector × time window). The in-process approach keeps the deployment simple. + +## Decision + +### 1. Time-windowed grouping by (victim_ip, vector) + +When an event arrives with correlation enabled, the engine looks for an existing **signal group** with matching `(victim_ip, vector)` whose window has not yet expired. If found, the event joins that group. If not, a new group is created with `window_expires_at = now + correlation.window_seconds`. + +This is the simplest grouping key that captures "multiple sources agreeing about the same attack." Port-level granularity is deliberately omitted from grouping — different detectors may report different top ports for the same DDoS vector, and requiring port-exact matches would defeat corroboration. + +### 2. Weighted confidence aggregation + +Each signal source has a configurable weight (default 1.0). The derived confidence for a signal group is the weighted average: + +``` +derived_confidence = Σ(event_confidence_i × source_weight_i) / Σ(source_weight_i) +``` + +This allows operators to express trust levels: a FastNetMon ban (weight 2.0) contributes more to derived confidence than a Prometheus alert rule (weight 0.8). + +### 3. Optional corroboration with backward compatibility + +The `min_sources` parameter (default 1) controls how many distinct sources must contribute before a signal group can trigger a mitigation: + +- **min_sources=1** (default): A single event from any source can trigger a mitigation if its confidence meets the threshold. This preserves current behavior — existing deployments see no change. +- **min_sources=2+**: Requires corroboration. A single source's event is recorded in the signal group but does not trigger a mitigation until additional sources confirm. + +Per-playbook overrides allow operators to require corroboration for some vectors (e.g., UDP floods from noisy detectors) while keeping single-source triggering for others (e.g., SYN floods from a trusted detector). + +### 4. Integration point: between event storage and policy evaluation + +The correlation step is inserted after the event is persisted (ensuring no data loss) and before policy evaluation (ensuring corroboration is checked before any mitigation decision). When correlation is disabled (`enabled: false`), this step is skipped entirely — the code path is identical to v0.13.0. + +### 5. Database-backed signal groups + +Signal groups are stored in PostgreSQL (`signal_groups` and `signal_group_events` tables) rather than in-memory. This ensures: + +- Groups survive prefixd restarts during the correlation window. +- The reconciliation loop can expire stale groups. +- Multiple prefixd instances (future) share the same group state. +- Full auditability of which events contributed to each mitigation decision. + +A nullable `signal_group_id` column on the `mitigations` table links each mitigation to the signal group that triggered it, enabling end-to-end explainability. + +### 6. Configuration in prefixd.yaml with hot-reload + +Correlation configuration lives in the main `prefixd.yaml` under a `correlation:` section. Using `#[serde(default)]` ensures omitting the section entirely produces a disabled (backward-compatible) config. Configuration changes are picked up on `POST /v1/config/reload` without restarting the daemon. + +## Consequences + +### Positive + +- Operators can combine weak signals from multiple detectors into high-confidence mitigation decisions. +- Backward compatible: existing single-detector deployments work unchanged (min_sources=1, correlation disabled by default). +- Per-playbook overrides give fine-grained control over which attack vectors require corroboration. +- Database-backed groups provide full auditability and survive restarts. +- Weighted confidence lets operators tune trust levels per detection source. + +### Negative + +- Adds latency to the ingestion path when correlation is enabled (database lookup for existing group + insert/update). Mitigated by indexes on `(victim_ip, vector, status)`. +- Increases database write volume (one signal_group_events row per event). Acceptable given the expected event rates (tens to low hundreds per minute). +- When min_sources > 1, there is a window where an attack is detected but not yet mitigated (waiting for corroboration). Operators must understand this trade-off. + +### Neutral + +- The existing `EventCorrelator` in `src/policy/correlation.rs` (scope-matching) remains unchanged. It serves a different purpose (TTL extension for same-scope mitigations) and operates independently of multi-signal correlation. +- Signal group expiry is handled by the existing reconciliation loop, adding minimal new complexity to the scheduler. diff --git a/docs/adr/README.md b/docs/adr/README.md index efa7fef..0fbea64 100644 --- a/docs/adr/README.md +++ b/docs/adr/README.md @@ -25,5 +25,6 @@ Format follows [Michael Nygard's template](https://cognitect.com/blog/2011/11/15 | [015](015-health-endpoint-split.md) | Split health endpoint (public liveness + authenticated detail) | Accepted | 2026-02-18 | | [016](016-cursor-pagination.md) | Cursor-Based Pagination (Replacing Offset) | Accepted | 2026-03-18 | | [017](017-notification-routing-preferences.md) | Per-Destination Event Routing and Notification Preferences | Accepted | 2026-03-18 | +| [018](018-multi-signal-correlation-engine.md) | Multi-Signal Correlation Engine | Accepted | 2026-03-19 | ADRs are numbered sequentially as written.

When correlation.enabled, find/create signal group, add event, check corroboration — skip mitigation if threshold not met. - Add signal_group_id to Mitigation domain type and DB layer - Add CorrelationContext to MitigationResponse with signal_group_id, derived_confidence, source_count, corroboration_met, contributing sources, and explanation string - Enrich GET /v1/mitigations/{id} with full correlation context - Add correlation summary to GET /v1/mitigations list items - Update WebSocket MitigationCreated broadcast with correlation data - Add correlation section to incident report markdown generation - Transition signal group to 'resolved' when mitigation is created - Add signal group expiry sweep to reconciliation loop with corroboration timeout metric - Add find_expired_signal_groups to RepositoryTrait with Mock and Postgres implementations - 14 new integration tests covering: min_sources=1 triggers, min_sources=2 blocks/triggers, disabled bypass, EventResponse shape, low confidence blocking, duplicate source counting, batch endpoint, mitigation detail correlation, list correlation summary, guardrail enforcement, incident report correlation section, signal group resolution --- src/api/handlers.rs | 353 +++++++++++++++++++++- src/db/mock.rs | 10 + src/db/repository.rs | 36 ++- src/db/traits.rs | 2 + src/domain/mitigation.rs | 7 + src/policy/correlation.rs | 1 + src/policy/escalation.rs | 1 + src/scheduler/reconcile.rs | 35 ++- tests/integration.rs | 534 ++++++++++++++++++++++++++++++++++ tests/integration_postgres.rs | 2 + 10 files changed, 965 insertions(+), 16 deletions(-) diff --git a/src/api/handlers.rs b/src/api/handlers.rs index 49a9eb5..c6da696 100644 --- a/src/api/handlers.rs +++ b/src/api/handlers.rs @@ -52,6 +52,24 @@ pub struct EventResponse { pub mitigation_id: Option, } +/// Correlation context attached to a mitigation that was created via the +/// correlation engine's corroboration logic. +#[derive(Clone, Debug, Serialize, ToSchema)] +pub struct CorrelationContext { + /// Signal group ID that triggered this mitigation + pub signal_group_id: Uuid, + /// Derived confidence (weighted average of contributing events) + pub derived_confidence: f32, + /// Number of distinct detection sources + pub source_count: i32, + /// Whether corroboration threshold was met + pub corroboration_met: bool, + /// List of contributing detection sources + pub contributing_sources: Vec, + /// Human-readable explanation of the correlation decision + pub explanation: String, +} + #[derive(Clone, Debug, Serialize, ToSchema)] pub struct MitigationResponse { /// Unique mitigation identifier @@ -98,6 +116,10 @@ pub struct MitigationResponse { pub acknowledged_at: Option, /// Operator who acknowledged the mitigation pub acknowledged_by: Option, + /// Correlation context (present when mitigation was created via + /// corroboration from the signal correlation engine) + #[serde(skip_serializing_if = "Option::is_none")] + pub correlation: Option, } impl From<&Mitigation> for MitigationResponse { @@ -125,6 +147,10 @@ impl From<&Mitigation> for MitigationResponse { reason: m.reason.clone(), acknowledged_at: m.acknowledged_at.map(|t| t.to_rfc3339()), acknowledged_by: m.acknowledged_by.clone(), + // Correlation context is populated asynchronously by handlers + // that have access to the signal group data.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implement dedicated FastNetMon signal endpoint that: - Accepts FastNetMon's native JSON notify format (ip, action, attack_details) - Classifies attack vector from per-protocol traffic breakdown - Computes confidence from action type via configurable mapping (ban=0.9, partial_block=0.7, alert=0.5, overridable per-source) - Returns EventResponse shape for compatibility - Requires authentication - Stores raw payload for forensics Add confidence_mapping field to SourceConfig for per-source action→confidence overrides. Add route, OpenAPI registration, 4 unit tests and 7 integration tests covering: valid payload, default/overridden confidence mapping, malformed payload (400), auth requirement (401), source field verification, and OpenAPI spec inclusion. --- src/api/handlers.rs | 255 +++++++++++++++++++++++ src/api/openapi.rs | 10 +- src/api/routes.rs | 1 + src/correlation/config.rs | 99 +++++++++ tests/integration.rs | 422 ++++++++++++++++++++++++++++++++++++++ 5 files changed, 784 insertions(+), 3 deletions(-) diff --git a/src/api/handlers.rs b/src/api/handlers.rs index bd7cd2b..b6c5571 100644 --- a/src/api/handlers.rs +++ b/src/api/handlers.rs @@ -4262,6 +4262,261 @@ async fn process_alertmanager_alert( } } +// ========================================================================== +// FastNetMon signal adapter +// ========================================================================== + +/// FastNetMon webhook payload (JSON notify format). +/// +/// Accepts FastNetMon's native notify format with IP, attack details, +/// direction, and bandwidth metrics.

Per-playbook `correlation` overrides in `playbooks.yaml`. Hot-reloadable via `POST /v1/config/reload`. - **Alertmanager webhook adapter** — `POST /v1/signals/alertmanager` accepts Alertmanager v4 webhook payloads. Maps labels/annotations to attack event fields (vector, victim_ip, bps/pps, severity→confidence). Handles batched alerts with per-alert results, resolved alerts (→ withdraw), fingerprint dedup. Returns 400 for malformed payloads (Alertmanager won't retry 4xx). See [ADR 019](docs/adr/019-signal-adapter-architecture.md). +- **FastNetMon webhook adapter** — `POST /v1/signals/fastnetmon` accepts FastNetMon's native JSON notify payload. Classifies attack vector from traffic breakdown (UDP/SYN/ICMP/TCP), maps action type to confidence (ban=0.9, partial_block=0.7, alert=0.5, configurable), uses `attack_uuid` for dedup. Returns `EventResponse` shape for script compatibility. +- **Correlation config API** — `GET /v1/config/correlation` (secrets redacted) and `PUT /v1/config/correlation` (admin only, validates, writes YAML, hot-reloads). Correlation config reloaded alongside inventory/playbooks/alerting on `POST /v1/config/reload`. +- **Signal adapter E2E tests** — 3 end-to-end tests in `tests/integration_e2e.rs` verifying full-stack signal adapter flows through real Postgres and GoBGP: Alertmanager→signal group→mitigation, FastNetMon→signal group→mitigation, multi-source corroboration (FastNetMon + Alertmanager → same group → mitigation with FlowSpec in RIB). Marked `#[ignore]` by default (require Docker). ### Changed diff --git a/docs/api.md b/docs/api.md index e4e5d07..d186b28 100644 --- a/docs/api.md +++ b/docs/api.md @@ -687,6 +687,154 @@ Accepts an [Alertmanager v4 webhook payload](https://prometheus.io/docs/alerting > **Note:** Alertmanager will not retry 4xx errors, so malformed payloads return 400 to prevent infinite retry loops. +**Alertmanager Configuration Snippet:** + +To point Alertmanager at prefixd, add a webhook receiver to your `alertmanager.yml`: + +```yaml +receivers: + - name: 'prefixd' + webhook_configs: + - url: 'http://prefixd.example.com/v1/signals/alertmanager' + http_config: + authorization: + type: Bearer + credentials: '' + send_resolved: true +``` + +### FastNetMon Webhook + +```http +POST /v1/signals/fastnetmon +Authorization: Bearer +Content-Type: application/json +``` + +Accepts FastNetMon's native JSON notify payload.

Concurrent event submissions for same (victim_ip, vector) could trigger a 500 from the unique constraint (idx_signal_groups_open_unique). The CTE handles sequential races but truly concurrent inserts can fail. Added retry-on-conflict logic: when INSERT fails with unique violation (23505), retry with a SELECT to find the group that won the race. 2. GET /v1/mitigations list returned empty contributing_sources [] and explanation "" for correlated mitigations, while detail returned full data. Made both fields Optional and set to None in list view (omitted from JSON via skip_serializing_if), keeping full data in detail view. --- src/api/handlers.rs | 27 +++++---- src/db/repository.rs | 40 ++++++++++++-- tests/integration.rs | 101 +++++++++++++++++++++++++++++++++- tests/integration_postgres.rs | 45 +++++++++++++++ 4 files changed, 197 insertions(+), 16 deletions(-) diff --git a/src/api/handlers.rs b/src/api/handlers.rs index 0424809..dbe3923 100644 --- a/src/api/handlers.rs +++ b/src/api/handlers.rs @@ -54,6 +54,11 @@ pub struct EventResponse { /// Correlation context attached to a mitigation that was created via the /// correlation engine's corroboration logic. +/// +/// The list endpoint provides a lightweight summary with only the core fields +/// (signal_group_id, derived_confidence, source_count, corroboration_met). +/// The detail endpoint populates the full context including contributing_sources +/// and explanation. #[derive(Clone, Debug, Serialize, ToSchema)] pub struct CorrelationContext { /// Signal group ID that triggered this mitigation @@ -64,10 +69,12 @@ pub struct CorrelationContext { pub source_count: i32, /// Whether corroboration threshold was met pub corroboration_met: bool, - /// List of contributing detection sources - pub contributing_sources: Vec, - /// Human-readable explanation of the correlation decision - pub explanation: String, + /// List of contributing detection sources (populated on detail endpoint only) + #[serde(skip_serializing_if = "Option::is_none")] + pub contributing_sources: Option>, + /// Human-readable explanation of the correlation decision (populated on detail endpoint only) + #[serde(skip_serializing_if = "Option::is_none")] + pub explanation: Option, } #[derive(Clone, Debug, Serialize, ToSchema)] @@ -781,8 +788,8 @@ async fn handle_ban( derived_confidence, source_count, corroboration_met: true, - contributing_sources: unique_sources, - explanation: explanation.explanation, + contributing_sources: Some(unique_sources), + explanation: Some(explanation.explanation), }); tracing::info!( @@ -1163,8 +1170,8 @@ pub async fn list_mitigations( derived_confidence: group.derived_confidence, source_count: group.source_count, corroboration_met: group.corroboration_met, - contributing_sources: vec![], - explanation: String::new(), + contributing_sources: None, + explanation: None, }); } } @@ -1258,8 +1265,8 @@ pub async fn get_mitigation( derived_confidence: group.derived_confidence, source_count: group.source_count, corroboration_met: group.corroboration_met, - contributing_sources: unique_sources, - explanation: explanation.explanation, + contributing_sources: Some(unique_sources), + explanation: Some(explanation.explanation), }); } } diff --git a/src/db/repository.rs b/src/db/repository.rs index 45b5aff..e86e4f5 100644 --- a/src/db/repository.rs +++ b/src/db/repository.rs @@ -900,7 +900,12 @@ impl RepositoryTrait for Repository { // If another request already created a group for (victim_ip, vector, status='open'), // we return the existing one.
