Getting Started with NIST CSF and 800-53
The National Institute of Standards and Technology (NIST) publishes two of the most widely referenced cybersecurity frameworks in the world:- NIST Cybersecurity Framework (CSF) 2.0 - A voluntary framework for managing and reducing cybersecurity risk, organized around six core functions. Used by organizations of all sizes and sectors.
- NIST SP 800-53 Rev. 5 - A comprehensive catalog of security and privacy controls, primarily used by US federal agencies and their contractors. Increasingly adopted by private sector organizations seeking a rigorous control baseline.
Activate NIST CSF and/or NIST 800-53 under Settings - Frameworks. You can activate both - Matproof automatically maps controls between them so you avoid duplicate work.
NIST CSF 2.0 - The Six Core Functions
CSF 2.0 (released February 2024) organizes cybersecurity activities into six functions:Govern (GV)
Establish and monitor cybersecurity risk management strategy, expectations, and policy. New in CSF 2.0.
Identify (ID)
Understand your assets, business environment, risks, and supply chain to manage cybersecurity risk.
Protect (PR)
Implement safeguards to ensure delivery of critical services.
Detect (DE)
Identify the occurrence of cybersecurity events in a timely manner.
Respond (RS)
Take action regarding a detected cybersecurity incident.
Recover (RC)
Maintain plans for resilience and restore capabilities impaired by a cybersecurity incident.
NIST 800-53 - Control Families
NIST SP 800-53 Rev. 5 contains over 1,000 controls organized into 20 families:| Family | Code | Description |
|---|---|---|
| Access Control | AC | Access enforcement, least privilege, account management |
| Awareness and Training | AT | Security awareness, role-based training |
| Audit and Accountability | AU | Audit logging, review, analysis |
| Assessment, Authorization, and Monitoring | CA | Security assessments, system authorization |
| Configuration Management | CM | Baseline configuration, change control |
| Contingency Planning | CP | Backup, recovery, continuity |
| Identification and Authentication | IA | User identification, MFA, credential management |
| Incident Response | IR | Incident handling, reporting, monitoring |
| Maintenance | MA | System maintenance, tools, remote maintenance |
| Media Protection | MP | Media access, transport, sanitization |
| Physical and Environmental Protection | PE | Physical access, environmental controls |
| Planning | PL | Security planning, rules of behavior |
| Program Management | PM | Risk management strategy, enterprise architecture |
| Personnel Security | PS | Screening, termination, transfer |
| PII Processing and Transparency | PT | Privacy, consent, data processing |
| Risk Assessment | RA | Risk assessment, vulnerability scanning |
| System and Services Acquisition | SA | System development lifecycle, supply chain |
| System and Communications Protection | SC | Boundary protection, cryptography, transmission security |
| System and Information Integrity | SI | Flaw remediation, malicious code protection, monitoring |
| Supply Chain Risk Management | SR | Supply chain controls, component authenticity |
You do not need to implement all 1,000+ controls. Select a baseline (Low, Moderate, or High) based on your system’s security categorization (FIPS 199), then tailor controls to your environment.
Which Framework Should I Use?
| Use Case | Recommended Framework |
|---|---|
| Building a cybersecurity program from scratch | Start with CSF 2.0 for structure, add 800-53 controls for implementation detail |
| US federal agency or contractor (FISMA) | 800-53 is mandatory |
| FedRAMP cloud authorization | 800-53 Moderate or High baseline |
| Private sector, non-regulated | CSF 2.0 is typically sufficient |
| Mapping to multiple frameworks | CSF 2.0 maps well to ISO 27001, DORA, and other frameworks |
| Detailed technical controls needed | 800-53 provides the most granular control catalog available |
Recommended Implementation Plan
Most commercial organizations implementing 800-53 voluntarily choose the Moderate baseline. It provides strong security coverage without the full rigor of the High baseline required for national security systems.
CSF 2.0 Profiles and Tiers
Profiles
CSF profiles describe your organization’s current and target cybersecurity posture. Create two profiles in Matproof:- Current Profile - where you are today (based on your control assessment results)
- Target Profile - where you need to be (based on risk appetite, business requirements, and regulatory obligations)
Tiers
CSF implementation tiers describe the degree of rigor in your cybersecurity risk management:| Tier | Description |
|---|---|
| Tier 1 - Partial | Ad hoc, reactive. Limited awareness of cybersecurity risk. |
| Tier 2 - Risk Informed | Risk management practices are approved by management but may not be organization-wide. |
| Tier 3 - Repeatable | Risk management practices are formally established, regularly updated, and informed by threat landscape changes. |
| Tier 4 - Adaptive | Organization adapts cybersecurity practices based on lessons learned and predictive indicators. Continuous improvement. |
Next Steps
- Risk Management - risk assessments aligned to NIST methodology
- Controls - working through CSF and 800-53 control sets
- Incidents - incident response workflow configuration
- Audit Programs - security assessments and continuous monitoring
