Process Metadata — Detection Telemetry

Collection and providers

Collect read-only process inventory with PID plus start time/stable identity, command line and collection time; restrict access to potentially sensitive arguments.

• osquery: Scheduled host-state queries; supported tables and privileges vary by OS. Select a table that actually exposes the required object.
• Linux Audit plus inventory snapshots: Events explain changes; snapshots describe state at collection time.

Configuration

• Define the inventory query, allowed host set, interval and least-privileged reader. Store a stable asset ID, observation time and collector version.
• Keep successive snapshots and calculate additions, removals and changed attributes. Pair state changes with audit events when available.
• Export collector health and missed-poll counts so a missing snapshot is not misclassified as a missing asset.

Synthetic event example

Project-normalized synthetic JSON, not a native provider log, captured event, attack verdict or validated detection. A parser/adapter is required for a real SIEM. Example names, IPs and values are fictional.

  }
}

Visibility and validation

Snapshots miss short-lived objects and do not identify who caused a change. A generic inventory agent is not guaranteed to expose firmware or kernel-level details.

• Record the lab scope, collector version, effective configuration and expected source fields before testing.
• Use an approved benign action or read-only snapshot appropriate to this type. For destructive, privileged or physical effects, use a reviewed fixture or existing authorized evidence instead of causing the effect.
• Verify the native source record locally and at the collector; compare timestamps, identity, object, action/result and the type-specific fields listed below. Save a redacted real capture separately from the synthetic example.
• Check a normal baseline and collector-loss case. Fixture parsing proves parser behavior only; it does not prove sensor coverage or malicious-behavior detection.
