What is the primary objective of **FISMA**?

**FISMA's primary objective is to provide a comprehensive framework for federal agencies to develop, document, implement, and maintain risk-based information security programs protecting the confidentiality, integrity, and availability of federal information and systems.** Enacted in 2002 and modernized in 2014, it mandates agency-wide programs using NIST's Risk Management Framework (RMF) with seven steps: Prepare, Categorize (FIPS 199), Select (SP 800-53), Implement, Assess, Authorize, and Monitor. Oversight involves OMB for policy, DHS/CISA for operations, and IGs for annual evaluations.

Who is legally or professionally required to comply with **FISMA**?

**FISMA legally requires compliance from all federal executive branch civilian agencies and their contractors operating or processing federal information systems.** This includes federal contractors, cloud providers (via FedRAMP), systems integrators, and state/local entities administering federal programs (e.g., Medicaid). Excludes national security systems. CISOs, CIOs, AOs, and SAOPs bear direct responsibilities; vendors must align for federal contracts.

Does **FISMA** require an external audit or third-party certification?

**FISMA requires annual independent evaluations by agency Inspectors General (IGs), who may use third-party assessors, but does not mandate external certification like ISO.** IGs assess using CISA metrics across NIST CSF functions, assigning maturity levels (1-5). Contractors face agency-driven assessments; FedRAMP provides reusable authorizations for cloud. Evidence includes SARs and POA&Ms.

How often should an assessment for **FISMA** be performed?

**FISMA requires annual IG independent evaluations of agency security programs, supplemented by continuous monitoring per NIST SP 800-137.** RMF Assess step validates controls ongoing; high-value assets demand near real-time via CDM tools. Agencies report annually to OMB; major incidents trigger real-time notifications to CISA/Congress.

What are the consequences of non-compliance with **FISMA**?

**Non-compliance with FISMA results in unfavorable IG reports, OMB remediation directives, reduced funding, contract losses, and debarment for contractors.** Agencies face operational constraints, mission disruptions, and public scrutiny via OMB's annual report to Congress. Contractors risk termination under DFARS; no direct fines, but repeated failures lead to GAO oversight and heightened CISA interventions.

An **FISMA** be mapped to other international frameworks?

**FISMA does not officially map to other frameworks in its statutory requirements, focusing solely on U.S. federal civilian systems via NIST RMF and SP 800-53.**

What is the first step to begin implementing **FISMA**?

**The first step to implement FISMA is the RMF Prepare phase: establish governance, assign roles (CIO, CISO, AO, SAOP), and create a complete system inventory.** Develop a risk management strategy, RACI matrix, and CMDB as foundational artifacts for subsequent Categorize, Select, and ongoing RMF steps.

What is the primary objective of **NIST 800-53**?

**NIST SP 800-53 provides a catalog of security and privacy controls to protect organizational operations, assets, individuals, other organizations, and the Nation from diverse threats and risks.** Revision 5 organizes **1,100+ controls** into **20 families** (e.g., AC Access Control, SR Supply Chain Risk Management, PT PII Processing and Transparency), emphasizing **outcome-based** language, **functionality**, and **assurance**. Controls address confidentiality, integrity, availability (CIA), and privacy risks from hostile attacks, human errors, natural disasters, and supply chain threats. Integrated with **SP 800-53B baselines** (Low/Moderate/High per FIPS 199) and **SP 800-53A assessments**, it supports the **Risk Management Framework (RMF)** in SP 800-37 for risk-informed selection, tailoring, implementation, assessment, authorization, and monitoring.

Who is legally or professionally required to comply with **NIST 800-53**?

**Federal agencies and contractors processing federal information are legally required to implement NIST SP 800-53 controls under FISMA and OMB A-130.** **SP 800-53B mandates** minimum controls from baselines for federal systems. Contractors face contractual obligations via FedRAMP (mapping to 800-53 subsets) and DFARS for CUI. Voluntary adoption applies to state/local governments, critical infrastructure, cloud providers, and private entities seeking robust programs. Target stakeholders include authorizing officials, CIOs, privacy officers, developers, procurement officials, and assessors.

Does **NIST 800-53** require an external audit or third-party certification?

**No, NIST SP 800-53 does not require external audits or third-party certification; it mandates internal assessment of control effectiveness using SP 800-53A procedures.** Organizations assess via **examine, test, interview** methods, documenting in Security Assessment Reports (SARs) for RMF authorization. Independent assessments may be needed for high-impact systems or reciprocity, but federal policy drives external reviews (e.g., FedRAMP 3PAO audits). Continuous monitoring (CA-7) ensures ongoing validation without prescribed certification.

How often should an assessment for **NIST 800-53** be performed?

**NIST SP 800-53 assessments occur continuously via RMF monitoring, with full reassessments at least annually or upon significant changes.** **SP 800-53A** defines determination statements for risk-based frequencies: high-impact controls (e.g., AU-6 audit analysis) require near-real-time monitoring; others quarterly/annually. Categorization per FIPS 199 drives cadence; tailor via **SP 800-53B** for system-specific intervals, documented in security plans.

What are the consequences of non-compliance with **NIST 800-53**?

**Non-compliance with NIST SP 800-53 for federal entities risks FISMA violations, contract termination, fines ($10K–$50K per violation), and loss of authorization to operate (ATO).** Agencies face OMB oversight, IG audits, and funding cuts; contractors lose FedRAMP eligibility and eligibility for government work. Operationally, it amplifies breach impacts, regulatory probes, litigation, and reputational damage from unmitigated CIA/privacy risks.

Can **NIST 800-53** be mapped to other international frameworks?

**Yes, NIST provides official mappings from SP 800-53 Rev. 5 to NIST CSF, NIST Privacy Framework, and ISO/IEC 27001:2022.** Crosswalks in the OLIR catalog show coverage relationships for multi-framework alignment, supporting gap analysis and reporting. Mappings indicate overlap, not strict equivalence; organizations must validate tailoring for specific requirements.

What is the first step to begin implementing **NIST 800-53**?

**The first step is system categorization per FIPS 199 to determine Low/Moderate/High impact levels for confidentiality, integrity, and availability.** This informs **SP 800-53B baseline selection** (plus privacy baseline), followed by risk assessment (RA family), tailoring, and RMF Prepare step documentation.
