What is the primary objective of FedRAMP?

FedRAMP standardizes the security assessment, authorization, and continuous monitoring of cloud service offerings (CSOs) for U.S. federal agencies. Its "assess once, use many times" model eliminates duplicated reviews, enabling reuse across agencies while aligning with NIST SP 800-53 Rev 5 controls and FIPS 199 impact levels (Low, Moderate, High).

Who is legally or professionally required to comply with FedRAMP?

FedRAMP is mandatory for cloud service providers (CSPs) handling federal data unless narrow exceptions apply. Federal agencies must use FedRAMP-authorized CSOs for external cloud services per OMB policy; CMMC requires them for DoD contractors. Non-compliance bars federal procurement access.

Does FedRAMP require an external audit or third-party certification?

Yes, FedRAMP mandates independent assessments by accredited Third-Party Assessment Organizations (3PAOs). A2LA-accredited 3PAOs produce Security Assessment Reports (SARs) using NIST SP 800-53A procedures, validating SSPs and controls before agency Authorization to Operate (ATO).

How often should an assessment for FedRAMP be performed?

FedRAMP requires continuous monitoring with monthly deliverables and annual 3PAO reassessments. Quarterly vulnerability scans and POA&M updates supplement; full assessments occur yearly or upon major changes to maintain Marketplace authorization.

What are the consequences of non-compliance with FedRAMP?

Non-compliance results in loss of Authorization to Operate (ATO), Marketplace delisting, and federal contract ineligibility. Persistent POA&M failures or sponsor withdrawal revoke status; agencies may terminate services, exposing CSPs to procurement bans and revenue loss exceeding $20M per contract.

Can FedRAMP be mapped to other international frameworks?

FedRAMP baselines map directly to NIST SP 800-53 Rev 5 controls, enabling alignment with frameworks like CMMC. No formal mappings to non-U.S. standards exist; overlays support reuse for U.S.-focused programs, but international equivalence requires gap analysis.

What is the first step to begin implementing FedRAMP?

Conduct FIPS 199 categorization to select the impact baseline (Low ~156 controls, Moderate ~323, High ~410, or LI-SaaS ~45 assessed). Develop the System Security Plan (SSP) using PMO templates, secure agency sponsorship, and engage a 3PAO for readiness assessment.

What is the primary objective of ISO 27017?

ISO 27017 provides cloud-specific implementation guidance for 37 ISO/IEC 27002 controls plus 7 additional cloud-focused controls (CLD series) to secure cloud services within an ISO 27001 ISMS. Published in 2015, it addresses shared responsibilities between cloud service providers (CSPs) and cloud service customers (CSCs), covering multi-tenancy segregation (CLD.9.5.1), virtual machine hardening (CLD.9.5.2), asset removal/return, administrative operations (CLD.12.1.5), customer monitoring (CLD.12.4.5), and network alignment (CLD.13.1.4).

Who is legally or professionally required to comply with ISO 27017?

No organization is legally required to comply with ISO 27017, as it is a voluntary code of practice, not a legal mandate. Professionally, CSPs and CSCs with significant cloud footprints adopt it to demonstrate due diligence, meet procurement demands, and align with regulations like GDPR/CCPA via enhanced ISMS controls; ~94% of organizations use cloud, with 61% reporting incidents driving adoption.

Does ISO 27017 require an external audit or third-party certification?

ISO 27017 does not support standalone third-party certification or require a separate external audit. It is implemented and assessed within an ISO 27001 certification audit, where certification bodies evaluate its controls (e.g., 37 extended + 7 CLD) as part of the ISMS scope, often issuing combined certificates.

How often should an assessment for ISO 27017 be performed?

ISO 27017 assessments occur as part of ISO 27001 surveillance audits, typically annually, with full re-certification every three years. Organizations must continuously monitor cloud controls via risk assessments, addressing changes in services or threats, supported by tools for ongoing evidence collection.

What are the consequences of non-compliance with ISO 27017?

Non-compliance with ISO 27017 carries no direct penalties, as it is not legally binding. Indirect consequences include heightened breach risk from unaddressed cloud issues (e.g., misconfigurations in 61% of incidents), failed procurements, regulatory scrutiny under data laws, and competitive disadvantage without ISO 27001-integrated cloud controls.

Can ISO 27017 be mapped to other international frameworks?

Yes, ISO 27017 maps directly to ISO 27001 Annex A and ISO 27002 controls, with its 7 CLD controls aligning to frameworks like NIST SP 800-53 and CSA STAR. It supports multi-framework compliance (e.g., SOC 2, PCI-DSS) by providing cloud-specific overlays, enabling unified evidence for procurement and audits.

What is the first step to begin implementing ISO 27017?

Conduct a cloud-specific risk assessment within your ISO 27001 ISMS to identify applicable controls from the 37 ISO 27002 extensions and 7 CLD controls. Define scope, shared responsibilities (CLD.6.3.1), and update the Statement of Applicability before technical implementation.
