CC1.5Accountability for internal control responsibilitiesSOC 2Control Environment

Official Requirement

The entity holds individuals accountable for their internal control responsibilities in the pursuit of objectives.

Source: AICPA Trust Services Criteria (2017), incorporating COSO principles

In Plain English

The people responsible for controls are evaluated on whether those controls actually operate. Annual performance reviews reference security responsibilities. When a control fails or evidence is missing, the owner is held accountable through a documented process. This is the criterion that connects your RACI matrix to actual accountability, assigning ownership is not enough if there are never consequences for non-performance.

On-premises implementation and evidence

Performance reviews referencing security responsibilities

Implementation steps

  1. Confirm annual reviews are conducted and documented for all staff; retain the review summary (not detailed scores) as evidence
  2. For staff owning security controls (e.g., the person responsible for patch management), their review should reference whether the control was maintained
  3. When a control has failed during the period, document the gap, the owner, and the corrective action, this demonstrates accountability rather than just acknowledging the failure
