The 7 Steps (SP 800-37 Rev 2)

#
Step
Purpose
1
Prepare
Establish context, roles, strategy, and readiness at organization, mission, and system levels
2
Categorize
Categorize the system and information based on impact analysis
3
Select
Select and tailor controls (typically from SP 800-53 / 800-53B)
4
Implement
Implement controls; document as-implemented details
5
Assess
Determine if controls are implemented correctly, operating as intended, and producing desired outcomes
6
Authorize
Senior official accepts residual risk (authorization decision)
7
Monitor
Ongoing awareness — control effectiveness, changes, and risk reporting

After Prepare, later steps can be nonsequential when the organization already has artefacts (Rev 2 flexibility).

Frequently Asked Questions

Is RMF only for federal systems?

It is designed for federal information systems. Contractors often mirror it for FedRAMP and related discipline.

Where do baselines enter?

In the Select step, typically via SP 800-53 and SP 800-53B Low, Moderate, or High baselines.

How does RMF relate to CSF?

RMF is a risk process for systems. CSF is an outcome-oriented Framework. They are complementary, not substitutes.
