CCSFP Online Practice Questions

Explanation:
HITRUST defines sample sizes for manual controls based on the frequency of operation. For controls that operate weekly, the required sample size is 5 items. This ensures that the assessor can evaluate consistency over multiple weeks without excessive burden. For example, if access logs are reviewed weekly, five weeks of logs must be tested. A higher frequency (e.g., daily controls) requires larger samples, such as 25. Conversely, less frequent controls (e.g., monthly or quarterly) may only require 2 or 1 sample. The structured sampling methodology provides consistency across assessments, ensures sufficient evidence for scoring, and prevents under-testing of critical controls.

Explanation:
When an entity submits an assessment to their External Assessor, the responses are locked to preserve the integrity of the submission. However, changes can still be made if the assessor reverts a Requirement Statement back to the entity. This allows management to adjust responses, provide new evidence, or clarify details before the assessor finalizes validation. HITRUST itself does not revert requirement statements during the assessment phase, as that authority rests with the assessor. Once the assessment is submitted to HITRUST QA, responses cannot be modified. This process ensures proper control while still giving flexibility for corrections during the assessor review.

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.

Explanation:
HITRUST defines sample sizes for manual controls based on their frequency of operation. For daily controls, such as system log reviews or daily backup checks, the required sample size is 25 items. This sample size is designed to provide sufficient evidence that the control is consistently applied over time while remaining manageable for assessors. For weekly controls, the sample size is smaller (5), and for monthly or quarterly controls, it is smaller still (2 or 1). The 25-item rule ensures daily processes are tested across a meaningful timeframe (roughly a month of working days) to validate reliability. This standardized approach ensures comparability across assessments and prevents under-testing.

Assessors must maintain independence and avoid conflicts of interest.
If David assisted in remediating a gap, he cannot also validate the remediation, as that would compromise objectivity.
HITRUST requires separation of consulting/remediation support from assurance/validation activities.
Extract Reference (HITRUST CSF Assurance Program Independence Standards [0141]):
External Assessors may not validate remediation efforts they directly assisted in, to preserve independence.
