NIST Implementation
Direct answer: Effective NIST implementation starts with clear business and security objectives, then follows a structured program cycle across categorization, control selection, implementation, assessment, authorization, and continuous monitoring.
The e-InnoSec team emphasizes the approach "Do it Right the First-Time." Despite years of investment, many organizations feel their NIST program implementation is still inadequate, budget intensive, and repetitive.
NIST is one of the best documentation available to address various aspects of cybersecurity, and in general, the program implementation is large and complex. Most of the time it's not about size but lack of understanding related to the NIST basics and fundamentals. Moreover, organizations are not sure as to why they are implementing NIST. Is it just a checkbox from the compliance perspective or is it about organization security? The clarity of the objective will help develop the strategic plan for NIST program implementation. In the initial phases, it's all about people compare to the process and technology. The right program implementation deserves the right people with the right skills.
Please see the test below. If you can organize the following concepts from NIST in sequential order to match the stages listed, you can determine the overall approach to the NIST implementation program cycle.
What is the core objective of NIST implementation?
The objective is not to complete a compliance checkbox. The objective is to build a security program that reduces risk, aligns with business priorities, and can be sustained with the right people, process, and technology roadmap.
Clear strategic intent helps teams avoid rework and define how standards and controls should be applied across the organization.
How do you map NIST concepts to the program cycle?
Use this concept test to align key references with the implementation lifecycle:
| FIPS 199 | SP 800-37 | SP 800-53 |
| SP-800-70 | SP 800-53A | SP 800-17 |
| SP 800-30 | FIPS 200 |
What are the eight stages of the NIST program cycle?
- Categorize
- Select
- Supplement
- Document
- Implement
- Assess
- Authorize
- Monitor
What do the NIST stages mean at a high level?
The next step is to apply this approach to each aspect of NIST. A practical way to kickstart implementation is a workshop so stakeholders gain better understanding of the FIPS and NIST standards referenced above. The stages are explained below at a high level:
| Categorize - Define criticality/sensitivity of information systems according to potential impact of loss |
| Select - Select baseline (minimum) security controls to protect the information system; apply tailoring guidance as appropriate |
| Supplement - Use risk assessment results to supplement the tailored security control baseline as needed to ensure adequate security and due diligence |
| Document - Document in the security plan, the security requirements for the information system and the security controls planned or in place |
| Implement - Implement security controls; apply security configuration settings |
| Assess - Evaluate whether security controls are implemented correctly and operating as intended |
| Authorize - Determine risk to agency operations, agency assets, or individuals and, if acceptable, authorize information system operation |
| Monitor - Continuously track changes to the information system that may affect security controls and reassess control effectiveness |
