Question No : 1
Is the Payment Card Industry C Data Security Standard (PCI-DSS) a Risk Management Framework (RMF)?
正解:
Explanation:
PCI-DSS is not considered a Risk Management Framework (RMF). Instead, it is a prescriptive security standard developed by the Payment Card Industry Security Standards Council to protect cardholder data. PCI-DSS specifies detailed control requirements such as encryption, access control, and monitoring, but it does not provide a holistic risk management structure for identifying, analyzing, and responding to risks. RMFs, such as NIST RMF or HITRUST’s risk-based approach, focus on identifying risks, applying controls proportionally, and managing risk over time. HITRUST includes PCI-DSS as a regulatory factor that can generate applicable requirements in assessments, but PCI-DSS itself is not classified as an RMF.

Question No : 2
Is the HITRUST CSF a replacement standard for HIPAA or NIST 800-53?
正解:
Explanation:
The HITRUST CSF is not intended to replace existing regulatory frameworks such as HIPAA or security standards like NIST 800-53. Instead, the CSF harmonizes and integrates requirements from these and other authoritative sources into a single certifiable framework. For example, HIPAA Security Rule provisions and NIST 800-53 controls are mapped into the CSF domains and requirement statements. This enables organizations to demonstrate compliance with multiple frameworks through one assessment. However, the CSF does not eliminate or supersede the original obligations. Covered entities must still comply with HIPAA, and federal contractors may still need to align with NIST standards directly. The CSF serves as a consolidated implementation tool, not a legal or regulatory replacement.
Reference: HITRUST CSF Overview C “Integration vs. Replacement of Standards”; CCSFP Study Guide C “How CSF Harmonizes Authoritative Sources.”
Question No : 3
What type of deficiency would be identified in the following Requirement Statement scoring scenario?
Policy = 50%
Process = 50%
Implemented = 75%
Measured = 0%
Managed = 0%
正解:
Explanation:
In HITRUST scoring, deficiencies are identified when maturity levels fall below required thresholds for certification. In this case, the Policy, Procedure, and Implementation levels are not fully compliant, with scores of 50%, 50%, and 75% respectively. For certification-critical controls, HITRUST requires 100% Implementation, supported by adequate Policy and Procedure. Since the Implementation score is not at 100% and supporting maturity levels are below full compliance, this results in a Required Corrective Action Plan (CAP). The CAP ensures the organization addresses deficiencies through remediation. Unlike optional CAPs, which may apply to non-critical requirements, required CAPs must be documented and remediated to achieve certification. Thus, the correct classification of this scoring outcome is a Required CAP.
Reference: HITRUST Scoring Rubric C “Deficiency Types and CAP Triggers”; CCSFP Study Guide C “Scoring Outcomes and CAP Requirements.”
Question No : 4
On an r2 assessment, HITRUST requires evidence to be linked to all maturity levels that score above 25% for Policy and Procedure, and over 0% for Implementation, Measured, and Managed.
正解:
Explanation:
HITRUST enforces strict evidence requirements to maintain credibility of assessment results. For Policy and Procedure maturity levels, if a score above 25% is claimed, the organization must link appropriate evidence (e.g., documented policies, standard operating procedures). For Implementation, Measured, and Managed, evidence must be provided whenever a score greater than 0% is claimed. This ensures that claims are supported by objective artifacts rather than assertions. Evidence can include policy documents, monitoring reports, logs, meeting minutes, or audit records. HITRUST QA verifies that evidence is linked to requirement statements at each maturity level. Without linked evidence, scores may be reduced or reverted during QA. This policy ensures transparency, accountability, and prevents overstatement of control effectiveness.
Reference: HITRUST CSF Assurance Program C “Evidence Linking Requirements”; CCSFP Practitioner Guide C “Evidence Thresholds by Maturity Level.”
Question No : 5
For the maturity levels "Measured" and "Managed," any score above 50% requires the following supporting documentation. (Select all that apply)
正解:
Explanation:
When scoring Measured and Managed maturity levels in HITRUST, evidence requirements are more rigorous. If these levels are scored above 50%, organizations must demonstrate that formal processes exist to measure control performance, that reports are generated to monitor effectiveness, and that accountability for measurement and management is assigned.
Specifically:
Processes show how control gaps are tracked, risks mitigated, and remediation addressed.
Reports provide tangible outputs proving monitoring activities (e.g., audit logs, vulnerability reports).
Responsible individuals must be identified to show governance and ownership of measurement functions.
Organizational scoping factors, while important for tailoring requirements, do not serve as evidence of maturity scoring. HITRUST’s QA team requires this documentation to confirm that high maturity levels are not claimed without demonstrable evidence of ongoing monitoring and governance.
Reference: HITRUST Scoring Rubric C “Measured and Managed Requirements”; CCSFP Study Guide C “Evidence for Advanced Maturity Levels.”
Question No : 6
The Subscribers Comments field should be populated with the rationale for any requirement statement marked not-applicable (N/A).
正解:
Explanation:
When a requirement statement is marked as Not Applicable (N/A) in MyCSF, HITRUST requires the organization to provide a justification. This justification must be entered into the Subscriber Comments field. The rationale explains why the requirement does not apply to the entity’s environment, systems, or data. For example, if a requirement relates to payment card data but the organization does not process credit cards, the Subscriber Comments field should document that no PCI-DSS scope exists. HITRUST QA reviews these justifications to ensure N/As are applied appropriately. Failure to document rationale can result in QA findings or required CAPs. This requirement preserves transparency and prevents misuse of the N/A designation to exclude applicable controls.
Reference: HITRUST CSF Assurance Program C “N/A Requirements and Justification”; CCSFP Study Guide C “Use of Subscriber Comments.”
Question No : 7
During HITRUST's QA phase of a Validated Assessment, HITRUST picks a sample of Control Objectives to review the assessor's validation and testing procedures.
正解:
Explanation:
HITRUST conducts a QA review of every validated assessment to confirm that assessors followed the methodology and applied consistent testing. QA does not re-test every control; instead, HITRUST selects a sample of Control Objectives across the assessment. For each sample, HITRUST reviews assessor notes, evidence, and testing procedures to ensure accuracy and completeness. This sampling approach balances efficiency with assurance, allowing HITRUST to evaluate the assessor’s work without duplicating the entire validation process. If issues are found, QA may expand its review
or return the assessment for clarification. This process ensures that validated assessments meet HITRUST’s quality standards before reports or certifications are issued.
Reference: HITRUST Assurance Program C “QA Review Procedures”; CCSFP Practitioner Guide C “QA Sampling of Control Objectives.”
Question No : 8
The Offline Assessment function allows assessors which capability?
正解:
Explanation:
The Offline Assessment function in MyCSF is designed to improve assessor productivity. It allows assessors to download the requirement statements from a specific assessment object into an Excel spreadsheet. This spreadsheet can be used to gather responses, evidence notes, and preliminary scoring while working offline or in collaboration with client teams. Once complete, the responses can be uploaded back into MyCSF for validation and QA preparation. This feature does not allow assessors to download the entire HITRUST CSF framework (that is restricted to the Reference Library), nor does it permit bypassing MyCSF for QA submission. It is a workflow aid, not a replacement for the platform.
Reference: MyCSF User Guide C “Offline Assessment Feature”; CCSFP Training C “Using Offline Mode for Efficiency.”
Question No : 9
Vulnerability testing should never be performed on client systems by an external assessor.
正解:
Explanation:
HITRUST requires independent validation of security controls, and vulnerability testing is a critical part of that process. External assessors are expected to review vulnerability management programs and may conduct their own independent vulnerability testing to validate results. While many organizations perform internal scans, assessors may request additional testing or re-scans if evidence is insufficient. The notion that external assessors should “never” perform such testing is incorrect. In fact, the assurance program allows assessors to conduct testing directly, provided it is within agreed scope and does not disrupt production systems. This ensures the assessor can independently verify that vulnerabilities are managed appropriately and controls are functioning as intended.
Reference: HITRUST CSF Assurance Program C “Vulnerability Testing Requirements”; CCSFP Practitioner Guide C “Assessor Role in Security Testing.”
Question No : 10
Where in MyCSF can the CSF framework be browsed?
正解:
Explanation:
In MyCSF, the Reference Library is the designated area where users can browse the entire HITRUST CSF framework. This includes domains, control references, requirement statements, and illustrative procedures. The Reference Library provides an organized view of the framework that is independent of any active assessment object. This feature is especially useful for entities preparing for scoping, training, or developing internal control mappings. While the Search function allows keyword lookups and the Home page provides general dashboards, only the Reference Library offers the structured, domain-by-domain framework view. This ensures that users can review and study the CSF in its entirety before or during assessment preparation, without needing to navigate through specific assessment objects.
Reference: MyCSF User Guide C “Reference Library Navigation”; CCSFP Study Guide C “CSF Structure in MyCSF.”
Question No : 11
In an i1 assessment a Control Reference score of 62 would yield which result?
正解:
Explanation:
In an i1 assessment, scoring follows a pass/fail logic tied to CAP requirements. If a Control Reference scores below the defined threshold (typically 83 for i1 assessments), any gaps within its requirement statements must be addressed with a required Corrective Action Plan (CAP). A score of 62 is below the threshold, meaning it cannot be accepted without remediation. This ensures organizations remediate key cybersecurity hygiene gaps, even in a moderate assurance assessment. Optional CAPs are not used in i1 assessments, as the assurance program emphasizes mandatory remediation for below-threshold controls. Certification cannot be granted with unresolved required CAPs. Therefore, the correct outcome for a score of 62 in an i1 Control Reference is a required CAP.
Reference: HITRUST CSF Assurance Program C “i1 Assessment Scoring Rules”; CCSFP Practitioner Guide C “CAP Requirements in i1 Assessments.”
Question No : 12
If an organization has a policy against uploading sensitive data to third parties, what option would facilitate providing evidence to the HITRUST QA team to support maturity level scoring?
正解:
Explanation:
HITRUST accommodates organizations that cannot upload sensitive evidence to the MyCSF portal due to corporate or regulatory policies. The mechanism for this is QA Tasks. Through QA Tasks, HITRUST QA reviewers can request clarifications, additional evidence, or narrative responses, which can be provided without uploading sensitive raw data. This method allows entities to describe processes, reference documents, or provide redacted information while maintaining compliance with their internal data-handling policies. Options such as “Live QA” or “Onsite visits” are not part of the standard assurance program workflow. Escalated QA refers to dispute resolution or additional reviews and does not address evidence handling. QA Tasks are the standard method HITRUST uses to facilitate communication and evidence review without violating data-handling restrictions.
Reference: HITRUST Assurance Program Requirements C “QA Task Process”; CCSFP Study Guide C “Evidence Handling in QA.”
Question No : 13
Which of the following is NOT one of the Technical risk factors?
正解:
Explanation:
Technical risk factors in HITRUST scoping include elements that influence the size and complexity of the IT environment. Examples are Number of Users (reflecting identity management challenges), Number of Transactions (indicating workload and exposure volume), and Accessible from the Internet (highlighting attack surface considerations). These factors affect how many requirement statements are assigned and the level of implementation required. However, Number of Facilities is not considered a technical factor. Instead, facilities are categorized under Organizational or Operational risk factors, since they represent physical locations and operational complexity rather than technical characteristics. This distinction ensures risk tailoring addresses both IT-centric and business-environment dimensions separately.
Reference: HITRUST CSF Methodology C “Risk Factor Categories and Examples”; CCSFP Study Guide C “Scoping with Technical vs. Organizational Factors.”
Question No : 14
Which assessment type tests against requirement statements considered essential to cybersecurity hygiene?
正解:
Explanation:
The HITRUST e1 and i1 assessments are streamlined, moderate-effort assurance models designed to evaluate an entity’s implementation of essential cybersecurity hygiene controls. These assessments focus on baseline security practices recognized across industries as foundational for protecting sensitive information. The e1 is intended for smaller organizations or those with limited resources, covering a subset of controls that address basic hygiene. The i1 provides expanded coverage beyond e1, testing against controls deemed critical for medium assurance levels. By contrast, the r2 is the most rigorous and risk-tailored assessment, covering a broader and more detailed control set. Targeted assessments are specialized and do not focus broadly on hygiene. Therefore, the e1 and i1 assessments are the correct answers.
Reference: HITRUST Assurance Program Overview C “e1, i1, r2 Comparison”; CCSFP Practitioner Guide C “Cybersecurity Hygiene in e1 and i1 Assessments.”
Question No : 15
Is additional work required by the assessor to generate the NIST Cybersecurity Framework Report?
正解:
Explanation:
The NIST Cybersecurity Framework (CSF) Report in HITRUST is a derivative output that is automatically generated within the MyCSF platform. When an entity completes a HITRUST assessment (e1, i1, or r2), MyCSF uses the mapping of HITRUST control requirements to the NIST CSF categories and subcategories to produce the report. Because these mappings are embedded into the framework, assessors do not need to perform additional testing, create mappings manually, or provide separate evidence. The effort invested in validating HITRUST requirement statements is sufficient, and MyCSF generates the NIST CSF alignment report as an output. This provides organizations with the ability to demonstrate NIST CSF alignment to stakeholders without duplicating work. Therefore, additional work is not required from assessors―making the correct answer No.

HITRUST for NIST CSF Reporting.”
