Examining the value of complementary user entity controls (CUECs) within SOC reports
For SOC reports, user control considerations have long been important. But what are CUECs, and what is their role in maintaining a robust control environment?
Essentially, complementary user entity controls (CUECs) are operative measures that exist on a user-entity level within a service-based organization or business. To understand the CUEC meaning, it’s important to note that the term user entity is used to refer to any organization that borrows a financial auditing or transactional service from another business.
CUECs ensure that user entities’ access to specific services are controlled within the scope of what both organizations have already agreed upon. Within this scope, CUECs help align the reports with their allotted subsections and control objectives. For example, along with control activities, CUECs help complete SOC 1 (control objective), SOC 2 (trust service criteria) and SOC 3 type reports forming an integral part of the system of controls.
CUECs within SOC reporting
In terms of the roles that CUECs play within SOC reports, it’s important to understand that SOC reports are often the result of a cohesive effort on the part of several individuals — all of whom have specific roles and responsibilities. Thus, the relationship between CUEC SOC reports and CUECs is especially important, as CUECs help in the design, formulation and execution of SOC reports.
Moreover, the use of CUECs within SOC reports help ensure that access is provided efficiently, leading to higher levels of productivity. In the vast majority of contemporary SOC CUEC reports, CUECs have become not only important but also essential components of ensuring fluidity, accuracy and proper completion.
Altogether, there are two different types of CUECs: complementary and compensating controls. While the former can be identified as cohesive controls that work together to ensure control objectives, the latter can be identified as one-off controls that are allocated when primary controls are needed for specific requirements or needs.
In terms of the party that is responsible for CUECs, this falls on user entities, who need to continuously and consistently create new CUECs that change according to the current demands and needs. This process, often referred to as CUEC mapping, is crucial for maintaining an effective control environment.
The risk of inefficient CUEC deployment
Another way of explaining the importance of such controls is to consider corporate emails for example. The use of corporate email addresses are only permitted so long as the individual using the email address is still employed by the corporation the address represents. In the case the individual no longer represents the company, CUECs help allow for a seamless and smooth transition toward access reallocation. Other examples of CUECs include anything from system encryption to monitoring services and contingency planning.
Without continuous monitoring, tracking and development, CUECs may fall short of allowing successful control environments, which could have an adverse effect on the general efficiency of the SOC report. CUECs should never be glossed over because of the additional work they often require. Even the smallest or most potentially unimportant vendor relationship can pose the greatest amount of risk to a SOC report if the appropriate CUECs are not properly considered and added. Without such controls, the SOC report is deemed to have an increased amount of risk, due to potentially missing protections, which are often considered the strict responsibility of the service organization. This is particularly crucial when considering what is CUEC in SOC report context and how it impacts overall compliance and security standards.
With a clear and transparent implementation of CUECs within a SOC report, the overall process can be easily explained throughout internal audits and external regulatory tests. This is where the concept of complementary user entity controls SOC 1 becomes particularly relevant, as it ensures that both service organizations and user entities are aligned in their control objectives.
CUECs are an integral component within any CUEC audit report. For any organization involved in financial auditing services, almost all SOC audit reports — including SOC 1, SOC 2 and SOC 3 — rely on CUECs for efficient auditing. The timely filing of SOC reports are a requirement within the SSAE and the AICPA rules, and are greatly reliant on CUECs.
It’s worth noting that CUECs are not the only type of complementary controls in SOC reporting. Complementary Subservice Organization Controls (CSOCs) also play a crucial role, especially when dealing with subservice organizations. The carve-out method in a type 2 report, for instance, may require careful consideration of both CUECs and CSOCs to provide a comprehensive system description and ensure all service commitments are met.
