CC4.2Evaluates and communicates internal control deficienciesSOC 2Monitoring Activities

Official Requirement

COSO Principle 17: The entity evaluates and communicates internal control deficiencies in a timely manner to those parties responsible for taking corrective action, including senior management and the board of directors, as appropriate.

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

In Plain English

When a control fails, someone finds out promptly and has the authority and the task to fix it. Deficiencies are not just logged, they are communicated to the right person, tracked to resolution, and reported to senior management if material. The evidence for this criterion is the gap between discovering a deficiency and closing it, and how that process was documented.

On-premises implementation and evidence

Deficiency tracking and escalation process

Implementation steps

  1. Use the work order system to log every identified control deficiency with: detection date, source (audit, pen test, monitoring), description, owner, target remediation date
  2. Review open deficiencies at the monthly security meeting; escalate to management any that are past their SLA or are of high severity
  3. Confirm closure with documented verification, a deficiency is not closed until the fix is confirmed to be working, not just when the remediation task is completed
