SOC Audit Checklist

Comprehensive SOC Audit Checklist for Effective Security Operations

March 16, 2023


SOC audits, short for System and Organization Controls, embody a framework of auditing standards born from the efforts of the American Institute of Certified Public Accountants (AICPA) to appraise the safeguards implemented by organizations in safeguarding their systems and data. Autonomously conducted by auditors external to the organization, these audits furnish reassurance to clients, business partners, and stakeholders that an organization has effectively and consistently fortified its systems and processes. Distinct types of SOC audits exist, namely SOC 1, SOC 2, and SOC 3. SOC 1 audits focus on financial reporting controls, whereas SOC 2 and SOC 3 audits concentrate on controls encompassing security, availability, processing integrity, confidentiality and privacy relating to an organization’s systems and data.

Presented below is a holistic checklist for executing a SOC audit, aimed at fostering a comprehensive evaluation while paying homage to the interconnectedness of the digital realm:

Section 1: Grasp the Scope

The preliminary stride of the audit entails a precise delineation of its scope. This involves identifying the organizational systems and processes that warrant evaluation. Key considerations encompass identifying specific business units, systems, applications, and data encapsulated within the audit’s purview.
Moreover, the scope encompasses defining the time frame under scrutiny, which may fluctuate contingent on the type of SOC audit and the applicable criteria. For example, SOC 1 audits may scrutinize a distinct financial reporting period, while SOC 2 audits may encompass a more extensive temporal span to comprehensively assess control effectiveness.

It is crucial to identify the intended recipients of the SOC report. By ascertaining the stakeholders relying on the report to assess an organization’s controls, such as customers, business partners, regulators, and investors, the scope definition embraces a holistic understanding of the audit’s boundaries and the anticipated utility of the SOC report.

Section 2: Articulate Control Objectives

The articulation of control objectives assumes paramount significance within the SOC audit process, for it establishes the yardstick against which an organization’s controls shall be measured. Control objectives materialize based on the specific SOC criteria applicable to the type of SOC audit underway (e.g., SOC 1, SOC 2, etc.).
The auditor embarks upon the identification of control objectives by perusing the SOC criteria and comprehending the specific requisites pertinent to the organization’s systems and processes. In light of this scrutiny, the auditor should delineate control objectives germane to the audit.

Control objectives often relate to distinct facets of an organization’s systems and processes, encompassing security, availability, processing integrity, confidentiality, and privacy. For instance, control objectives within a SOC 2 audit might encompass the assurance of safeguarding data against unauthorized access (security), ensuring systems remain available for use as needed (availability), guaranteeing accurate and complete transaction processing (processing integrity), preserving the confidentiality of sensitive data (confidentiality), and adhering to applicable privacy laws and regulations governing the handling of personal information (privacy).

Within the control objectives the auditor now embarks upon the task of discerning the pertinent controls for each objective. This endeavor entails a meticulous evaluation of the organization’s digital terrain, seeking out the specific controls woven into its fabric to address each objective. It is imperative for the auditor to identify any gaps or shortcomings in this technocratic landscape, urging remedial measures to align with the control objectives. The insights gleaned from this exploration will be instrumental in assessing the efficacy of the organization’s controls and tendering recommendations for enhancement where needed.

Section 3: Understanding the Distinct Types of SOC Audits

SOC 1 audits also known as Service Organization Control 1 audits primarily focus on assessing the effectiveness of financial reporting controls. These audits are relevant for organizations that provide services that could impact their clients’ financial statements, the purpose of a SOC 1 audit is to evaluate the controls and processes that service organizations have in place to ensure the accuracy, completeness and integrity of the financial information they provide to their clients.

On the other hand SOC 2 and SOC 3 audits concentrate on controls related to security, availability, processing integrity, confidentiality and privacy of an organization’s systems and data. The primary distinction between SOC 2 and SOC 3 audits lies in the level of detail and the intended audience for the resulting report.

SOC 2 audits are more comprehensive and provide a detailed examination of the controls and processes within an organization. The resulting report, known as a SOC 2 report, is typically intended for a restricted audience, such as clients, business partners, or stakeholders who require a deeper understanding of the organization’s controls.

In contrast, SOC 3 audits result in a SOC 3 report, which provides a summarized version of the controls assessed. This report is intended for a broader audience and can be freely distributed to anyone interested in gaining assurance about the organization’s controls without needing access to sensitive or detailed information.

By understanding these distinctions, organizations can determine which type of SOC audit is most relevant to their specific needs. SOC 1 audits are suitable for organizations providing services impacting financial reporting, while SOC 2 and SOC 3 audits focus on broader control objectives related to security, availability, processing integrity, confidentiality, and privacy.

Section 4: The Documented Frontier

The SOC audit voyage necessitates the charting of the control environment, a sacred act of documentation. In this realm of the digital domain, the auditor endeavors to capture the essence of the policies, procedures, and processes that bolster the control objectives unveiled in step 2.

To embark upon this documentation odyssey, the auditor delves into the annals of relevant literature, policy documents, procedural manuals, and other scriptures of the organization’s systems and processes. The auditor, a sage of inquiry, also engages in conversations with the luminaries within the organization, seeking to fathom the intricate design and intended operation of the controls.

This body of documentation shall weave together a vivid tapestry of the control environment. It shall unveil the secrets of control design, illuminate the guardians of sensitive data, unveil the rites of system availability. It shall disclose the enshrined rituals of control implementation, the enforcement of access controls, the rhythms of backups. It shall unfurl the timeless dance of control monitoring and maintenance, the scrutineers of security logs, the updaters of system configurations.

By chronicling the control environment in this manner, the auditor embarks upon an alchemical voyage, assessing the efficacy of the controls and proffering remedies for the betterment of the digital realm. This body of documentation, an anchor in the ever-changing seas of audits, enables the auditor to traverse time, comparing the current control environment with past epochs, perceiving the shifts that may herald impact upon the audit.
