 # cloud-security-service-model
 
-**Tagline:** A pragmatic, enterprise Cloud Security service operating model (Azure + Hybrid)
+[![CI](https://github.com/Coding-Autopilot-System/cloud-security-service-model/actions/workflows/ci.yml/badge.svg?branch=main)](https://github.com/Coding-Autopilot-System/cloud-security-service-model/actions/workflows/ci.yml)

+
+**Enterprise cloud security operating model** for Azure and hybrid environments — defines service scope, governance, controls-as-code, metrics, and measurable outcomes for security leaders and platform teams.
+
+Part of the [Coding-Autopilot-System](https://github.com/Coding-Autopilot-System) portfolio of enterprise AI and platform engineering artifacts.
 
 ## What this repo is
+
 This repository is a public-safe, enterprise-grade operating model for a **Cloud Security Service** delivered as a
 service/product. It defines scope, boundaries, governance, metrics, runbooks, and implementation stubs to help platform
 and security leaders stand up a predictable, measurable cloud security capability.
 
-## Who it’s for
+## Who it's for
+
 - Head of Cloud Platform Services
 - Security leadership (CISO org)
 - Cloud engineering leads
 - Audit/compliance stakeholders
 
 ## Problem it solves
+
 Organizations often treat cloud security as a toolset. This repo reframes it as a **service** with clear ownership,
 interfaces, measurable outcomes, and lifecycle management across Azure and hybrid/on-prem environments.
 
 ## Scope
+
 - Azure and hybrid coverage (Azure Arc and Azure Local/on-prem)
 - Policy, identity, logging, incident response, and governance
 - Controls as Code examples (policy, IaC, detection)
 
 ## Non-scope
+
 - Tenant-specific configurations or secrets
 - Production-ready infrastructure code
 - Vendor-specific operational details beyond Azure and hybrid scope
 
 ## Service boundaries (summary)
+
 - **We do:** define standards, manage policy-as-code, enable monitoring, coordinate incident response, provide evidence.
-- **We don’t:** own app code, operate app teams’ pipelines, or run business application production on their behalf.

 ## How to consume
+
 1. Start with the executive overview and service definition.
 2. Use the operating model and KPIs to set expectations.
 3. Apply the templates and runbooks in operational workflows.
 4. Extend implementation stubs in your own environment.
