Microsoft Sentinel is a high-impact surface for enterprise agents because read access can expose sensitive detections and investigations, and write access can change incidents, analytics rules, and automation. Claw EA treats Sentinel actions as permissioned execution: a Work Policy Contract (WPC) defines what an agent may do, a CST (scoped token) limits and binds each run, and model traffic routed through clawproxy produces gateway receipts and proof bundles for audit.
This page describes how to connect Microsoft Sentinel via official API with enterprise buildout controls, using OpenClaw as the baseline agent runtime. It is not a native connector page, and you should assume integration work is required for your tenant’s RBAC model and approvals.
Step-by-step runbook
Use this runbook when you want an agent to triage incidents, run KQL queries, or propose response actions without granting broad admin power in Microsoft Sentinel.
-
Pick an agent task and classify it as read-only or write-capable. Examples: “summarize incidents in a workspace” (read) versus “close incident with reason and add comment” (write). Treat any analytics rule, automation rule, connector, or playbook change as admin-level until proven otherwise.
-
Map Microsoft Sentinel and Azure RBAC roles to the minimum needed. Start with Microsoft Sentinel roles that match your task boundary, then narrow to custom roles if necessary. Document which identities can access which workspaces and what they can change.
-
Create or select an Entra ID workload identity for the agent. Use an app registration or managed identity depending on your environment, and restrict access using Conditional Access where applicable. For elevated write paths, put the privileged role behind PIM so activation is time-bounded and reviewable.
-
Define a WPC that encodes the allowed Sentinel operations. The WPC is a signed, hash-addressed policy artifact served by clawcontrols. Make “write” operations require explicit approval gates, and separate policy for “read only triage” versus “containment actions.”
-
Issue a CST (scoped token) per job and pin it to the WPC when needed. The CST is issued by clawscope with a scope hash and optional policy hash pinning. For Sentinel write jobs, use short TTLs and job-scoped binding to reduce replay risk.
-
Run the agent in OpenClaw with tool policy and sandboxing enabled. Use OpenClaw tool allowlists and sandbox modes to keep the agent’s local execution surface small, then add the Sentinel tool as a controlled integration via official API with enterprise buildout. If the agent can call a model, route model calls through clawproxy to obtain gateway receipts automatically.
-
Require proof on completion. Persist the proof bundle produced for the run, and verify it during reviews or incident response. When you need a human-readable audit view, store the resulting artifact as a Trust Pulse.
Threat model
Sentinel sits on your detection pipeline, so an agent mistake is not “just a bad answer.” The failure modes below are common when teams rely on prompt-only controls instead of policy-as-code with enforceable tokens and receipts.
| Threat | What happens | Control |
|---|---|---|
| Over-privileged identity (RBAC too broad) | An agent meant to triage can modify incidents, rules, or automation across multiple workspaces. | Least-privilege Microsoft Sentinel roles and workspace scoping, plus a WPC that denies write paths unless explicitly approved. Use PIM for roles that permit write or admin actions. |
| Prompt injection via incident content | Attacker-controlled strings inside an alert or incident drive the agent to run risky queries or take destructive actions. | Permissioned execution: the WPC defines allowable operations, and the CST enforces job-scoped permissions even if the model is manipulated. Keep OpenClaw tool allowlists tight and avoid elevated host tools for investigation-only agents. |
| Silent tampering with investigations | Incident status, severity, tags, or comments are changed without a clear chain of accountability. | Write and admin actions require WPC approval gates, a CST that is specific to the job, and explicit least-privilege auth scopes. Store the proof bundle and tie it to the ticket or change record. |
| Data over-collection and spill | Agent runs broad KQL queries and exports sensitive results into chat logs or downstream systems. | WPC constraints on query templates, time windows, and export behavior, plus OpenClaw sandboxing to limit where artifacts can be written. Redact sensitive logs at the runtime layer, and treat data egress controls as an enterprise buildout item if needed. |
| Replay of a previously authorized action | A “close incident” or “disable rule” action is repeated later using a copied credential or cached authorization. | Marketplace anti-replay binding using job-scoped CST binding, and short-lived CST TTLs. Proof bundles let reviewers see which job performed the action and when. |
| Plugin or tool misuse in the agent runtime | A malicious or misconfigured tool makes unexpected network calls or writes files that change future behavior. | OpenClaw tool policy and sandboxing reduce blast radius, and WPC rules define what remote actions are permissible. Gateway receipts focus specifically on model calls; combine them with runtime controls for tool execution boundaries. |
Policy-as-code example
Prompt guidance can be ignored under pressure, and it is not a security boundary. A WPC is the boundary: it is signed, hash-addressed, and fetched and verified by the execution path before any write-capable Sentinel operation is attempted.
Example JSON-like WPC sketch for Sentinel triage with a separate, gated write path:
{
"wpc_version": "v1",
"policy_name": "sentinel-triage-readonly",
"allow": [
{ "tool": "sentinel.api", "ops": ["incidents.list", "incidents.get", "alerts.list", "kql.query"] }
],
"deny": [
{ "tool": "sentinel.api", "ops": ["incidents.update", "incidents.close", "analyticsRules.create", "analyticsRules.update", "automationRules.update"] },
{ "tool": "exec", "ops": ["host"] }
],
"approvals": [
{
"name": "sentinel-write-approval",
"required_for": ["incidents.update", "incidents.close"],
"mode": "explicit"
}
],
"token_requirements": {
"cst_ttl_seconds_max": 900,
"require_policy_hash_pinning": true
}
}
Operationally: clawcontrols serves the WPC, clawscope issues a CST for the job that matches the scope hash and optionally pins the policy hash, and the Sentinel tool refuses to execute any denied operation even if the agent asks for it.
What proof do you get?
For model-assisted Sentinel runs, route model calls through clawproxy so you receive gateway receipts. These receipts provide a verifiable record of what the model was asked and what it returned, which is useful when an investigation depends on model-produced reasoning or summaries.
Claw EA bundles receipts and run metadata into a proof bundle for audit and verification. For organizational review or external auditors, you can store the resulting artifact as a Trust Pulse, keeping a stable reference to what was executed under which WPC and CST.
Rollback posture
Sentinel rollback is not one-size-fits-all, because some actions are additive (comments) and others are configuration changes (rules) that affect future detections. Treat rollback as part of the WPC design: if you cannot roll it back safely, you should not let an unattended agent do it.
| Action | Safe rollback | Evidence to keep |
|---|---|---|
| Read-only triage (list incidents, run KQL queries) | No rollback required, but restrict retention and sharing of query outputs. | Proof bundle with gateway receipts for model calls, plus job metadata (workspace, time range, query identifiers if applicable). |
| Add incident comment or tag | Remove or supersede with a corrective comment if policy allows; keep a clear correction note. | WPC hash, CST job binding, and proof bundle to show who/what authored the note and under which constraints. |
| Change incident status or severity | Revert to previous values based on a human review, ideally within a bounded time window. | Approval record referenced by the WPC gate, plus proof bundle for the run that performed the update. |
| Create or modify analytics rules | Disable the rule and restore a known-good version from change control; validate alert volume impact. | Change ticket reference, WPC that permitted the action, and proof bundle capturing the model involvement in the change proposal. |
| Modify automation rules or response playbooks | Disable the automation first, then revert configuration after review. | Strict WPC gate for admin paths, CST TTL evidence, and proof bundle stored for audit. |
FAQ
Is this a native Sentinel connector in Claw EA?
No. Microsoft Sentinel can be connected via official API with enterprise buildout controls, and the integration details depend on your tenant, workspaces, and RBAC model.
Why is prompt-only safety not enough for Sentinel agents?
Prompts do not enforce anything when the model is manipulated or the agent is misconfigured. A WPC plus CST turns the execution layer into an enforceable boundary that can deny write actions even when the agent requests them.
How do you keep write actions from happening “by accident”?
Separate read-only and write-capable WPCs, and require explicit approval gates for write operations. Keep the CST short-lived and job-scoped so the authorization cannot be reused outside the intended run.
What Microsoft identity controls should we align to?
Use Entra ID identities with least privilege, then add Conditional Access where it fits your environment. For elevated operations, use PIM so write-capable roles require activation and are time-bounded.
What can auditors verify after an incident?
They can verify gateway receipts for model calls and review the proof bundle for the run, including the WPC identity and CST binding. This helps distinguish “the model suggested” from “the system executed,” and shows which policy allowed the execution.
