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 including hostile attacks, human errors, natural disasters, and privacy risks.** Revision 5 organizes 20 control families (e.g., AC Access Control, SR Supply Chain Risk Management) with over 1,100 base controls and enhancements, emphasizing functionality and assurance through outcome-based statements. Controls are selected via SP 800-53B baselines (Low/Moderate/High per FIPS 199) and tailored within the RMF lifecycle.

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 baselines for federal systems. Contractors face contractual obligations (e.g., FedRAMP), while state/local governments, critical infrastructure, and private entities adopt voluntarily for robust risk management, especially with CUI.

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; assessments follow SP 800-53A procedures within the RMF.** Organizations conduct internal or independent assessments for authorization (ATO), with continuous monitoring via CA family controls. FedRAMP may involve third-party assessments, but the standard itself specifies organization-defined validation.

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

**NIST SP 800-53 assessments occur continuously via RMF monitoring, with full reassessments tied to risk changes, at least annually for high-impact systems.** SP 800-53A defines procedures; CA-7 requires ongoing monitoring of high-risk controls (e.g., real-time for AU-6 audit analysis), quarterly for moderate, and annual for low, adjusted by tailoring.

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, and loss of ATO.** Agencies face OMB oversight, IG audits, and funding cuts; contractors lose eligibility for federal work (e.g., FedRAMP revocation). Operationally, it amplifies breach risks to CIA and privacy.

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

**Yes, NIST provides official mappings from SP 800-53 Rev. 5 to NIST CSF, Privacy Framework, and ISO/IEC 27001:2022, indicating coverage but not equivalence.** Crosswalks in OLIR support multi-framework alignment; organizations validate mappings during tailoring for compliance overlap.

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, informing SP 800-53B baseline selection.** Follow RMF Prepare step: define scope, inventory assets, and document in security plans before selecting/tailoring controls.

What is the primary objective of **MLPS 2.0 (Multi-Level Protection Scheme)**?

**The primary objective of MLPS 2.0 is to establish a graded cybersecurity protection system ensuring security controls match the potential harm from system compromise to national security, social order, and public interests.** It classifies systems into five levels (1-5) based on impact severity, mandating commensurate technical, management, physical, and personnel controls per GB/T 22239-2020 and related standards.

Who is legally or professionally required to comply with **MLPS 2.0 (Multi-Level Protection Scheme)**?

**All network operators in mainland China must comply with MLPS 2.0 under Article 21 of the 2017 Cybersecurity Law.** This includes domestic enterprises, foreign-invested entities, cloud providers, and operators of IT, OT, IoT, big data, and industrial systems, enforced by Ministry of Public Security and local PSBs.

Does **MLPS 2.0 (Multi-Level Protection Scheme)** require an external audit or third-party certification?

**Yes, MLPS 2.0 requires external security reviews by licensed Chinese firms for Level 2+ systems, targeting a minimum score of 75/100.** PSB approval follows submission of audit results, documentation, and classification reports; Level 3+ mandates annual evaluations.

How often should an assessment for **MLPS 2.0 (Multi-Level Protection Scheme)** be performed?

**Assessments under MLPS 2.0 must occur biennially for Level 2, annually for Level 3, semi-annually for Level 4, and as mandated for Level 5.** Re-evaluations are also required post-major changes like cloud migrations or architecture updates.

What are the consequences of non-compliance with **MLPS 2.0 (Multi-Level Protection Scheme)**?

**Non-compliance with MLPS 2.0 results in fines up to 100,000 yuan, operational suspensions, system shutdowns, and intensified PSB inspections.** Enforcement links certification to business license renewals, with severe cases escalating to criminal liability.

Can **MLPS 2.0 (Multi-Level Protection Scheme)** be mapped to other international frameworks?

**Yes, MLPS 2.0 control domains—physical, network, data, operations, governance—map to ISO 27001 Annex A and NIST CSF categories.** Organizations leverage existing ISMS Statements of Applicability for gap analysis, though MLPS adds prescriptive grading and PSB oversight.

What is the first step to begin implementing **MLPS 2.0 (Multi-Level Protection Scheme)**?

**The first step is conducting a provisional self-assessment to classify systems into Levels 1-5 based on impact to national security, social order, and public interests.** Inventory assets, document rationale per GB/T 22240-2020, and prepare for Level 2+ expert review and PSB filing within 30 days.
