Governance & Compliance

Governance and compliance establish the organizational framework for information security by defining policies, information classification, regulatory compliance and continuous security improvement. Microsoft Purview and Microsoft Secure Score provide centralized governance capabilities across the Microsoft 365 environment.

Overview

Governance and compliance ensure that security controls are not only implemented technically but are also aligned with business objectives, regulatory requirements and organizational policies.

Microsoft Purview provides centralized capabilities for information classification, compliance assessments, audit logging and information governance across Microsoft 365 services.

Together with Microsoft Secure Score, these capabilities help organizations continuously improve their security posture while demonstrating compliance with applicable standards and regulations.

Business Need

Modern organizations must comply with numerous regulatory requirements while protecting sensitive information against unauthorized access, disclosure and misuse.

Security governance provides policies, accountability and measurable controls that ensure information assets remain protected throughout their lifecycle.

Governance processes also support continuous improvement by measuring security maturity, documenting compliance activities and identifying opportunities for reducing organizational risk.

Security Objective

Establish governance processes that support information classification, compliance management, security measurement and continuous improvement across the Microsoft 365 environment.

Architecture

Microsoft Purview serves as the central governance platform by providing capabilities for information protection, compliance assessments and audit logging.

Information is classified using sensitivity labels, while compliance assessments measure implementation progress against recommended controls. Microsoft Secure Score complements these capabilities by continuously evaluating the organization's technical security posture.
