Control Family

A control family is a grouping of related security controls that address a common security topic. For example, the Access Control (AC) family contains all controls related to managing who can access your systems and what they can do. NIST SP 800-53 organizes its controls into 20 families, while NIST SP 800-171 uses 14 families.

Control families help you organize your security program and ensure comprehensive coverage. Each family represents a distinct area of security that requires attention — from personnel security to incident response to system maintenance.

Why It Matters

Working through compliance family by family ensures nothing is overlooked. It also helps you assign subject-matter experts — your network team owns certain families, your HR team owns others, and your management owns the governance families.
