azure-monitor-security

azure-monitor-security is a skill for Claude Code, Codex from vinayaklatthe/microsoft-security-skills. It costs 201 tokens per session (2,174 once invoked), scanned A, original, MIT.

Azure Monitor and Log Analytics guidance for storing and using security logs. Log Analytics is the workspace that collects data used by Microsoft Sentinel, Defender for Cloud, and other Azure security tools.

In plain words
What is it for?
Use it to design workspaces, choose log storage tiers, set retention and archive periods, configure data collection rules, manage access, and control ingestion costs.
Why use it?
It helps balance searchable security data, retention requirements, and logging costs. It also helps reduce noisy data before it is stored and keep the workspace accessible to the right people.

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

azure-monitor-security 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 13d 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.

Azure Monitor & Log Analytics for Security

Microsoft Sentinel runs on a Log Analytics workspace. Defender for Cloud, Defender XDR hunting tables, Activity logs, and Diagnostic settings also flow there. The workspace strategy decides whether your security telemetry is complete, compliant, and affordable — or two of three.

This skill covers the security-side decisions in workspace design: tiering, retention, DCRs, RBAC, and cost.

When to use

Designing or refactoring the Log Analytics workspace(s) that back Sentinel and the broader security telemetry estate.

Do not use this skill for Sentinel detection authoring (sentinel-detection-engineering), App Insights instrumentation (appinsights-instrumentation), or non-security observability.

Log table tiers — pick per table

Tier Query latency Retention max Use case
Analytics Sub-second 730 days interactive Detections, hunting, dashboards
Basic Seconds (KQL with limits) 30 days interactive + archive High-volume "search if needed" logs
Auxiliary Slower / async 12 months interactive Low-touch compliance archive feeds
Archive (any tier) Search-job recall up to 12 years Long-tail evidence, regulatory hold

Microsoft has been re-naming/re-shaping these — verify current naming and pricing in your region before commit.

Approach

  1. Workspace topology.

    • Default: one Sentinel workspace per tenant for security signal — keeps correlation easy.
    • Regional / sovereign: separate workspaces where data residency or sovereignty requires.
    • Multi-workspace Sentinel: only when business reasons (M&A boundary, MSSP model) force it. Cross-workspace queries work but add complexity.
    • Don't split per-team; that fragments correlation.
  2. Use Azure Monitor Agent (AMA) for everything new. The Microsoft Monitoring Agent (MMA / Log Analytics agent) is retired. Migration paths via Defender for Cloud auto-provisioning and Sentinel solutions.

What this file has done since we first saw it

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.
