purview-insider-risk-management

purview-insider-risk-management is a skill for Claude Code, Codex from vinayaklatthe/microsoft-security-skills. It costs 245 tokens per session (2,026 once invoked), scanned A, original, MIT.

Guidance for Microsoft Purview Insider Risk Management, which finds and investigates potentially harmful user activity such as data theft by departing employees or intellectual-property leaks. It uses signals from Microsoft 365, devices, security tools, identity systems, and HR systems.

In plain words
What is it for?
Use it to choose insider-risk policies, connect HR data, tune alerts, investigate cases, and apply stronger data-loss controls to users whose risk is rising.
Why use it?
It helps security teams spot risky behaviour that may unfold over time instead of treating each event as an isolated alert. It also helps them tune policies and respond when a user's risk increases.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

purview-insider-risk-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Microsoft Purview Insider Risk Management

Insider Risk Management (IRM) correlates signals from across M365, endpoints, Defender, Entra, and HR systems to surface risky user activity — most importantly intent over time (e.g., the classic "departing employee exfiltrating customer lists 3 weeks before their last day"). It pairs with Adaptive Protection, which dynamically tightens DLP and CA policy on users whose risk score is rising.

When to use

Operationalizing insider risk detection beyond the program-level baseline: policy template selection, HRIS connector setup, alert tuning, case investigation, and Adaptive Protection rollout.

Do not use this skill for outbound DLP authoring (purview-dlp-policy, purview-advanced-dlp), eDiscovery (purview-ediscovery), or the high-level insider risk program framing (insider-risk-baseline).

Policy templates — pick by use case

Template What it detects
Data theft by departing users Exfil-type activity in the window around resignation/termination (requires HRIS connector)
General data leaks Risky upload/download/share/print regardless of HR signal
Data leaks by priority users Same as above, scoped to executives, M&A team, etc.
Data leaks by risky users Triggered by Adaptive Protection elevated risk level
Security policy violations Defender alerts indicating user circumvention
Risky browser usage Edge-for-Business browsing to risky sites with sensitive content
Risky AI usage Sensitive data sent to non-sanctioned AI apps (paired with Purview AI Hub)
Healthcare / patient data misuse (HIPAA scenarios) EMR access patterns
PII unauthorized access (financial) Sensitive data viewing outside scope

Approach

  1. Get the prerequisites right. Audit (Standard/Premium) on. Purview connectors for the data sources you need. Sensitivity labels and DLP at least baselined.

  2. Wire the HRIS connector. Without it, "departing user" templates have no trigger. Workday and SAP SuccessFactors via Microsoft Graph connectors are the common patterns; custom CSV import also supported. Map the resignation date, termination date, job-change date.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
