NIST Special Publication 800-53, titled "Security and Privacy Controls for Information Systems and Organizations," is a comprehensive framework developed by the National Institute of Standards and Technology (NIST) to provide guidelines for securing federal information systems and organizations. It outlines a catalog of security and privacy controls to protect against a wide range of threats, ensure compliance with federal regulations, and safeguard sensitive data.
Lazarus Alliance, a certified Third-Party Assessment Organization (3PAO), will collaborate directly with your organization to schedule your NIST 800-53 assessment. Our certified 3PAO assessors will assist in determining the appropriate impact level based on your company’s unique business and government requirements.
NIST Special Publication 800-53
There is no separate “NIST 800-53 audit” distinct from a FISMA audit in the federal context. A FISMA audit often incorporates NIST 800-53 controls as the evaluation criteria.
- Purpose and Scope:
- Provides a standardized set of security and privacy controls for federal agencies and their contractors.
- Applicable to all types of information systems, including cloud-based, on-premises, and hybrid systems.
- While designed for federal use, it’s widely adopted by private organizations for robust cybersecurity practices.
- Control Families:
- Organized into 20 control families, grouped by function, including:
- Access Control (AC): Managing user access to systems and data.
- Incident Response (IR): Preparing for, detecting, and responding to security incidents.
- Risk Assessment (RA): Identifying and evaluating risks to systems.
- System and Communications Protection (SC): Securing network and communication channels.
- Privacy Controls: Addressing privacy requirements, such as data minimization and transparency (e.g., Privacy Impact Assessments).
- Each family contains specific controls and enhancements tailored to different security needs.
- Organized into 20 control families, grouped by function, including:
- Control Structure:
- Controls are categorized into three baseline levels: Low, Moderate, and High, based on the system’s impact level (per FIPS 199).
- Each control includes:
- A unique identifier (e.g., AC-2 for Access Control).
- A description of the control’s purpose.
- Implementation guidance and supplemental information.
- References to related standards (e.g., FIPS, ISO/IEC).
- Implementation:
- Used in conjunction with NIST 800-37 (Risk Management Framework) to select, implement, assess, and monitor controls.
- Supports compliance with laws like FISMA (Federal Information Security Modernization Act) and regulations like FedRAMP for cloud services.
- Organizations tailor controls to their specific needs, environments, and risk profiles.
- Applicability:
- Mandatory for U.S. federal agencies and contractors handling federal data.
- Widely adopted by the private sector, including critical infrastructure, healthcare, and finance, due to its flexibility and robustness.
Frequently Asked Questions
What is FISMA and why is it important for federal agencies and contractors?
FISMA (Federal Information Security Modernization Act) is a U.S. law that mandates federal agencies and their contractors to develop, document, and implement an information security program to protect federal information systems. It ensures consistent security practices, risk management, and accountability, helping organizations avoid penalties, maintain contract eligibility, and safeguard sensitive data from threats like cyberattacks.
What is NIST 800-53, and how does it relate to FISMA audits?
NIST Special Publication 800-53 is a comprehensive catalog of security and privacy controls organized into 20 families (e.g., Access Control, Incident Response, Risk Assessment). It provides guidelines for protecting information systems against threats and ensuring compliance with laws like FISMA. In federal contexts, there is no separate "NIST 800-53 audit"—it's integrated into FISMA audits as the core evaluation framework, using controls tailored to the system's impact level (Low, Moderate, or High).
Who is the target audience for Lazarus Alliance’s FISMA/NIST audit services?
These services are primarily for U.S. federal agencies and contractors handling federal data, where compliance is mandatory. They're also ideal for private organizations in sectors like critical infrastructure, healthcare, finance, or those pursuing federal contracts, FedRAMP authorization, or robust cybersecurity—regardless of system type (cloud, on-premises, or hybrid).
| Impact Level | Baseline Controls (Approx.) | Key Use Cases | Reuse Scope |
|---|---|---|---|
| Low | ~125 NIST 800-53 Low controls | Public/low-sensitivity data (e.g., general websites) | SLED entities nationwide |
| Low+ | Enhanced Low (~150 controls) | Slightly elevated low-risk data (e.g., basic admin tools) | SLED entities nationwide |
| Moderate | ~325 NIST 800-53 Moderate controls + overlays | Confidential data (e.g., PII, financial records) | SLED entities nationwide |
| High | ~421 NIST 800-53 High controls + overlays | High-sensitivity data (e.g., critical infrastructure) | SLED entities nationwide |
| Core (Introduced May 2025) | 60 foundational Moderate controls (MITRE ATT&CK mapped) | Entry-level validation for progressing products | Broad pre-authorization access for SLED |
- Comprehensive Cybervisor™ Assessments using advanced software for low, moderate, and high-impact baselines.
- Ongoing proactive monitoring and 24/7 audit platform access.
What is the audit process with Lazarus Alliance?
As a certified Third-Party Assessment Organization (3PAO), Lazarus Alliance schedules assessments directly with your team, determines the appropriate system impact level based on FIPS 199 and your business needs, and evaluates controls using NIST 800-53. The process incorporates tools like the Security Trifecta methodology and Continuum GRC for tailored, risk-based assessments, leading to Authorization to Operate (ATO) recommendations and continuous monitoring support.
What are the key benefits of achieving NIST 800-53 and FISMA compliance?
Compliance strengthens your security posture against threats, ensures alignment with regulations like FedRAMP, HIPAA, and GDPR, and adopts a scalable, risk-based approach. It builds trust with stakeholders, reduces breach costs through proactive controls, enhances incident response, protects privacy (e.g., via data minimization for PII), and supports long-term efficiency and interoperability for federal or commercial operations.
How does Lazarus Alliance stand out as a FISMA/NIST audit provider?
Lazarus Alliance is an A2LA-accredited 3PAO (ISO/IEC 17020 certification #3822.01) with global experience conducting thousands of assessments via Cybervisor™ teams. They offer customized evaluations integrated with the NIST Risk Management Framework (800-37), proprietary tools for automated control mapping, and a focus on multi-regulatory compliance—ensuring efficient, high-quality results without separate NIST-only audits.
Can non-federal organizations benefit from NIST 800-53 audits?
Yes, while mandatory for federal entities, NIST 800-53 is widely adopted by private sector organizations for voluntary cybersecurity enhancements. It provides a flexible framework for protecting systems, meeting industry standards, and preparing for contracts or audits in regulated environments, making it valuable for any business prioritizing data security and privacy.
What role does privacy play in NIST 800-53 controls?
NIST 800-53 includes dedicated privacy controls (e.g., in the Privacy family) alongside security ones, emphasizing principles like data minimization, transparency, and consent for handling personally identifiable information (PII). This integration supports compliance with privacy laws like CCPA or GDPR, ensuring balanced protection of both security and individual rights in federal and commercial systems.
Benefits of NIST 800-53 Compliance
NIST 800-53 compliance offers numerous benefits for organizations, particularly those handling federal data, but also for private entities adopting the framework. Below is a concise list of key benefits:
