Detection telemetry and configuration
These contracts are selected through exact technique-to-data-component relationships or explicitly labelled planning overrides. Configure a collector at the relevant observation point; a telemetry name alone is not coverage.
Active Directory Object Access · source-mapped
DC0071 collection page — Enable Audit Directory Service Access and scoped object SACLs; interpret access masks and property GUIDs in their directory context.
Providers and collection configuration
- Use a lab-only GPO under Computer Configuration → Windows Settings → Security Settings → Advanced Audit Policy Configuration. Enable the specific subcategory named below.
- For object-level auditing, configure a narrow system access control list (SACL) on the test object in addition to policy. Do not audit an entire production directory by default.
- Forward Security events from the responsible host or controller; retain subject and target identities, object identifiers, result and original XML. Confirm effective policy with auditpol /get /category:*.
Required normalized fields: object_dn, access, actor.
Illustrative collection event
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.
{
"schema": "1200km.telemetry.example.v1",
"synthetic": true,
"timestamp": "2026-09-27T12:00:00Z",
"telemetry_id": "DC0071",
"collector": "illustrative-lab-collector",
"observation": {
"object_dn": "CN=LabUser,OU=Lab,DC=example,DC=test",
"access": "read_property",
"actor": "LAB\\analyst"
}
}
Visibility limits: A policy checkbox alone does not guarantee an event. Host role, SACL, success/failure selection and audit policy precedence matter. Directory changes may arrive as multiple records.
Command Execution · source-mapped
DC0064 collection page — Collect process command lines and relevant shell/interpreter audit; shell history alone is neither complete nor tamper-resistant.
Providers and collection configuration
- Enable Script Block Logging through the policy/configuration for the installed edition. Forward Microsoft-Windows-PowerShell/Operational for Windows PowerShell, or PowerShellCore/Operational for PowerShell 7.
- Retain script-block ID and fragment ordering alongside process creation. Protect access to collected script text; secrets may be included.
- On Linux, use narrowly scoped Audit execution rules for the lab account and supported architectures, and retain joined SYSCALL/EXECVE/PATH records.
Required normalized fields: interpreter, command_line, actor_uid, session_id.

"schema": "1200km.telemetry.example.v1",

"telemetry_id": "DC0064",
"collector": "illustrative-lab-collector",
"observation": {
"interpreter": "/bin/sh",
"command_line": "printf LAB_TELEMETRY_CHECK",
"actor_uid": 1000,
"session_id": "lab-session-1"
}
}
Visibility limits: Script content and process command lines are different signals. Logging may be partial, fragmented, filtered or disabled; never assume a command line reveals everything executed.
Process Creation · source-mapped
DC0032 collection page — Collect Sysmon ProcessCreate (1); preserve ProcessGuid and parent identifiers. Security 4688 is an alternative with separate audit/command-line settings.
Providers and collection configuration
- Microsoft Sysmon: Windows event-based collection; enable the event types needed below.
- Linux Audit: Linux alternative for supported system-call and file events; different semantics and fields.
- Apple Endpoint Security clients: macOS alternative where the subscribed event exists; requires an entitled, approved client, not an iOS collector.
- On a disposable Windows host, review the installed Sysmon schema and current configuration; merge scoped event filters into the existing policy rather than replacing it.
- Forward Microsoft-Windows-Sysmon/Operational to the lab collector. Preserve event ID, timestamp, computer, process identifiers and the original event.
- For Linux or macOS, select the equivalent sensor separately and test its emitted fields; a Windows event ID does not transfer across platforms.
Required normalized fields: process_guid, image, parent_image, command_line, user.
<EventFiltering>
<ProcessCreate onmatch="include">
<Image condition="is">C:\Windows\System32\whoami.exe</Image>
</ProcessCreate>
</EventFiltering>
This fragment only selects the named process. It is not a complete production policy. Inspect the installed schema with sysmon64 -s; preserve existing rules, then apply the reviewed complete configuration with sysmon64 -c <configuration-file>.

"parent_image": "C:\\Windows\\System32\\cmd.exe",
"command_line": "whoami",
"user": "LAB\\analyst"
}
}
Visibility limits: Event filtering and sensor versions change coverage. High-volume image-load and process-access collection needs tuning; endpoint events alone do not establish intent.
User Account Metadata · source-mapped
DC0013 collection page — Export an authorized directory/account inventory with stable IDs, roles, enabled state and collection time; compare snapshots without exposing credentials.
Providers and collection configuration
- 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.
- 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.
Required normalized fields: account_id, enabled, roles, inventory_time.

{
"schema": "1200km.telemetry.example.v1",
"synthetic": true,

"telemetry_id": "DC0013",
"collector": "illustrative-lab-collector",
"observation": {
"account_id": "user-lab-1",
"enabled": true,
"roles": [
"lab-reader"
],
"inventory_time": "2026-09-27T12:00:00Z"
}
}
Visibility limits: 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.

Technique-specific experiment contract
- Choose one procedure implementing T1201 Password Policy Discovery; identify the observable behavior in the source definition, not just its tactic.
- Record exact target, tool/version, inputs, privileges, network limits and approval. Never run an imported default target automatically.
- Enable the collection sources above and verify a benign baseline reaches the detector.
- Run only the approved isolated scenario; capture native events and an independent behavior observable.
- Evaluate the exact rule/model, restore the lab, and preserve configuration, event hashes, alerts, controls and misses.
