Splunk Add-on for Microsoft Security Setup

Prerequisites

Tool or access	Purpose	Verify
Bash and Python 3	Run bundled setup and validation helpers	bash --version && python3 --version
Required product/platform access	Inspect or configure the selected target	Complete the documented preflight
Credential files for live modes	Keep secrets out of chat	Verify paths only

Workflow Overview

┌───────────┐   ┌───────────────┐   ┌───────────────┐   ┌─────────────────┐
│ Preflight │ → │ Render/review │ → │ Apply/handoff │ → │ Validate evidence │
└───────────┘   └───────────────┘   └───────────────┘   └─────────────────┘

When to Activate

• Onboard, configure, render, or validate Microsoft Security / Defender data in Splunk.
• Preview and review the splunk microsoft security ta setup workflow before any live apply phase.
• Diagnose failed prerequisites, generated assets, configuration, or validation evidence.

Scope

Follow the documented read-only or render-first path whenever it is available. This skill does not imply permission to mutate live systems. Require explicit apply flags, protected credentials, and operator review for state changes.

Examples

Inspect the supported setup modes before selecting one:

bash skills/splunk-microsoft-security-ta-setup/scripts/setup.sh --help

Expected output: usage, supported modes, and required arguments are displayed without changing the target environment.

Inspect validation modes before running completion checks:

bash skills/splunk-microsoft-security-ta-setup/scripts/validate.sh --help

Expected output: offline, live, and completion options are displayed when the skill supports them; help exits without mutation.

Troubleshooting

Issue	Cause	Resolution
Preflight fails	A required tool or access path is missing	Resolve it before rendering or applying
Rendered assets are incomplete	Required non-secret inputs are absent	Complete intake and render again
Apply is blocked	Review, credentials, or explicit acceptance is missing	Use the documented handoff
Validation is incomplete	Live evidence is unavailable	Record the gap and keep completion open

TA Completion Gate

For every TA/add-on or dashboard companion run, satisfy the shared TA completion gate: configure and enable the data ingest path owned by this skill or its required companion, validate events or metrics in the target indexes/source types, and verify any pre-built/package-shipped dashboards are visible, macro-aligned, and returning data. If the package ships no dashboards, record that evidence explicitly and hand off dashboard use to the consuming app, ES/ITSI/ARI content, or readiness doctor.

Render-first automation for Splunk_TA_MS_Security (Splunkbase 6207, verified 4.0.0). The renderer emits reviewable inputs, macro overlays for package-shipped searches, an Entra app/client-secret account runbook, and validation SPL. It never handles Microsoft client secrets.

Workflow

bash skills/splunk-microsoft-security-ta-setup/scripts/setup.sh --render \
  --index microsoft_security --account-name ms_security_prod

bash skills/splunk-microsoft-security-ta-setup/scripts/setup.sh \
  --install --create-index --index microsoft_security

Configure the account from account-setup.md, review inputs.local.conf.template and macros.local.conf.template, then enable the selected inputs.

bash skills/splunk-microsoft-security-ta-setup/scripts/validate.sh --index microsoft_security

Readiness handoff:

bash skills/splunk-data-source-readiness-doctor/scripts/setup.sh \
  --phase collect --source-pack microsoft_security
