Define ownership and governance model for DevSecOps privileged groups

Implementation Effort: Medium – Inventorying privileged GitHub and Azure DevOps groups, assigning owners, and standing up access reviews and access packages spans identity engineering and the DevSecOps platform team. User Impact: Low – Group owners and administrators run the reviews and expiration policies; everyday developers are not prompted or affected. Lifecycle Stage: Govern

Overview

Establish a governance model for DevSecOps privileged groups by using Microsoft Entra access reviews, entitlement management, ownership, and expiration policies. Privileged security groups in DevSecOps environments — such as groups that grant organization-owner access to GitHub, project-collection administrator rights in Azure DevOps, or pipeline administrator roles — tend to grow over time and rarely shrink on their own. Members are added to meet immediate project needs, but removal is inconsistent because no formal process governs who reviews the membership, how often, or what happens when access is no longer justified.

Make ownership boundaries explicit so this control does not float between teams: this task lives in the DevOps Identity and Access area because it governs who can administer source platforms and pipelines. Identity engineering owns Microsoft Entra policy patterns and enforcement guardrails, while the DevSecOps platform owner is accountable for inventorying the privileged groups used by GitHub and Azure DevOps, assigning business owners for each group, and ensuring review outcomes are acted on. Keep role governance here — alongside privileged access policies and the periodic reduction of administrative permissions — and rely on Conditional Access enforcement for developer platform access and on program-level security dashboards and metrics reporting for monitoring and KPI reporting.

Microsoft Entra ID provides the tools to bring discipline to this problem. Prerequisite: Microsoft Entra ID P2 provides Access Reviews and Entitlement Management, with enhanced controls available through the Microsoft Entra ID Governance add-on. Access reviews enable recurring, scheduled evaluations of group membership where designated reviewers — group owners, managers, or the members themselves — must attest that each assignment is still warranted. Entitlement management bundles privileged group memberships into access packages with built-in approval workflows, time-limited assignments, and automatic expiration. Access packages support configurable assignment durations (e.g., 90-day access with optional renewal), enforcing time-bound DevOps privileges. Together, these capabilities ensure that membership in a privileged DevSecOps group is never indefinite by default and is always traceable to a documented business justification.

Without governance controls, organizations cannot answer basic questions that auditors and incident responders need: who approved this person's access, when was it last reviewed, and is it still necessary. Establishing lifecycle governance for privileged DevSecOps groups means every membership has an owner, a review cadence, and an expiration policy — turning static, forgotten group assignments into actively managed, continuously validated entitlements that align with Zero Trust expectations. This directly advances Use least privilege access by keeping privileged membership minimal, owned, and time-bound, and it supports Assume breach by making every entitlement continuously reviewable and revocable.
