"SOC" stands for "System and Organization Controls", encompasses several frameworks, primarily SOC 1, SOC 2, and SOC 3. These standards, established by the American Institute of Certified Public Accountants (AICPA), cater to different organizational needs, focusing on mainly on internal controls (called "Trust Criteria") over financial reporting and information security. SOC reports are often produced by third party auditors (usually a CPA or auditing firm) and are shared with clients and other stakeholders through a non-disclosure agreement (except for SOC 3 which is usually publicly available) to various stakeholders who are keen on understanding or evaluating the maturity level as well as risks around the use of an organization's systems and focus on the controls in place as well as any operating procedures that help govern or administer those systems. SOC reports can be produced for many reasons but most often they are produced when dealing with service organizations, or when performing cybersecurity assessments and also when assessing supply chain risks faced by an organization.
Types of SOC reporting
SOC reporting encompasses various levels, namely, SOC 1, SOC 2 and SOC 3, and each of them in turn divided into two distinct sub-levels: Type 1 and Type 2.
SOC 1 reporting is essential for service organizations, emphasizing controls that influence the accuracy and reliability of an organization’s client financial reports. Primarily designed for these organizations, SOC 1 necessitates rigorous controls to uphold the integrity of processed financial data. For individuals involved in developing financial operations or data-related software, a profound understanding of SOC 1 is crucial.
SOC 2 reporting predominantly applies to the technology and cloud computing industry, focusing on the security, availability, processing integrity, confidentiality, and privacy of customer data. It is centered around meticulous data management to safeguard its confidentiality and privacy. For developers operating in technology and cloud computing services, embracing SOC 2 is fundamental, serving as essential guidelines to bolster system security and operational efficiency.
SOC 3 reports stand apart from their counterparts by being publicly available, eliminating the need for a non-disclosure agreement. They are designed to be more accessible, catering to users seeking assurance of a service organization's controls without the exhaustive details found in SOC 2 reports. Often utilized for marketing purposes, SOC 3 reports display an organization's dedication to upholding robust standards of data security and operational practices.
Type 1 and Type 2 reports for SOC 1, SOC 2 and SOC 3
Before we proceed to the next section, I want to mention quickly that each of these types of reports are further classified into Type 1 and Type 2 reports. Type 1 reports are generally more straightforward and cost-effective, primarily focusing on the high-level design of the controls that are put in at a point of time. Type 2 reports are more comprehensive and time-consuming focusing on how these controls are used over a period of time. This could take anywhere between six or more months of evidence collection (sometimes less but usually accompanied with a report explaining why). Type 2 reports are also more common in SOC 2 reporting as clients are usually interested in knowing that the controls are actually practiced in a consistent manner.
Diving Deeper into SOC 2
In this article, I will delve deeply into the SOC 2 standard for these three key reasons:
SOC 2 reports occupy a unique position due to their extensive emphasis on operational controls, focusing on aspects like security, availability, processing integrity, confidentiality, and the privacy of a system’s data.
Contrasting with SOC 1, which mainly focuses on controls related to financial reporting, SOC 2 particularly concentrates on the management of sensitive data. This makes it incredibly relevant for technology and cloud computing organizations that manage customer information.
When compared to SOC 3, which offers a broader overview suitable for public consumption, SOC 2 presents a detailed and technical evaluation. It provides organizations with nuanced insights into their information security policies and the operational effectiveness of their systems. Such thorough examination makes SOC 2 exceptionally advantageous for organizations aiming to enhance their security measures, uphold customer trust, and maneuver through the intricacies of data protection with heightened precision and assurance.
Controls and Classifications
In the framework of SOC 2, controls are not strictly categorized as "mandatory" or "optional." Instead, they are aligned with the five "Trust Service Criteria" (TSC), which include Security, Availability, Processing Integrity, Confidentiality, and Privacy. We will now look at each of them one by one.
Common Criteria Controls (Security): These types of controls are essentially mandatory, as they form the foundation upon which the other criteria are built. The Security criteria encompass controls related to organizational communications, risk management, logical and physical access controls, system operations, and change management.
Additional Criteria (Availability, Processing Integrity, Confidentiality, and Privacy): These controls are more specialized, aligning with an organization’s specific services and operational requirements. These could be seen as “optional” in the sense that organizations choose which of these criteria are relevant and applicable based on their services, commitments, and regulatory requirements.
Supplementary or Additional Controls: Organizations may also implement supplementary or additional controls beyond those outlined in the “Trust Service Criteria” to cater to specific industry regulations or unique organizational needs. These are inherently optional and tailored to enhance and support the organization’s specific compliance posture. Each organization must carefully consider its unique operational context and regulatory landscape to determine which controls to implement and emphasize in its SOC 2 reporting, ensuring a robust and comprehensive approach to maintaining security, availability, processing integrity, confidentiality, and privacy.
COSO Framework and its relationship with SOC Framework
Something I should mention about the design of controls is that they are actually enabled by another pre-existing and effective framework from the COSO (Committee of Sponsoring Organizations of the Treadway Commission). The COSO framework and the SOC (Service Organization Control) frameworks can interoperate effectively due to their complementary nature in internal control and risk management. COSO provides a structured methodology for developing a comprehensive internal control system, emphasizing organizational governance, risk management, and compliance. When organizations implement COSO as part of their internal control environment, it forms a strong basis for achieving the trust service criteria essential for SOC reporting, such as security, availability, processing integrity, confidentiality, and privacy. The SOC framework, particularly in SOC 2 reports, relies heavily on predefined criteria (Trust Service Criteria) to evaluate the controls within service organizations. By leveraging the COSO framework’s principles, organizations can enhance their readiness and maturity in meeting the SOC framework's requirements, facilitating a more streamlined and robust SOC reporting process. This interoperability ensures that organizations have a well-rounded approach to managing risks, ensuring data security, and enhancing overall system reliability and integrity.
Now, let us get on with our exploration of the SOC framework and dive into the five pillars that form the core of the framework.
Security (often referred to as ‘Common Criteria Controls’)
SOC 2 necessitates that organizations set robust safeguards to protect systems and data against unauthorized access and potential breaches. These type of controls are often implemented through various mechanisms seen below.
Technological Safeguards: These safeguards include include firewalls as well as intrusion detection systems (often called as “IDS”) which act as the first line of defense, monitoring and restricting incoming and outgoing network traffic based on an organization’s previously established security policies. Another example of a technological safeguards is by utilizing encryption technologies to protect data at rest and in transit. This ensures that the data is unreadable and secure from unauthorized access during transmission or if a device containing sensitive data is lost or stolen.
Physical Safeguards: These safeguards include maintaining physical security by choosing data centers that are fortified against unauthorized access, natural disasters, and other physical threats. They can also be in forms such as biometric or card-based access control systems to ensure that only authorized personnel can access sensitive areas or information.
Administrative Safeguards: These safeguards include developing and maintaining comprehensive security policies and procedures that are regularly reviewed and updated. These should encompass aspects such as password policies, access controls, and incident response plans. Conducting regular training sessions to ensure that employees are aware of the security policies and are knowledgeable about the best practices and potential threats.
Proactive Measures: Examples include conducting regular audits to assess the effectiveness of security measures and identify potential vulnerabilities or areas of improvement and also ensuring that systems are regularly updated with the latest security patches to protect against known vulnerabilities.
Responsive Measures: These measures include having a well-established incident response plan to act swiftly and effectively in case of a security breach or incident. Implementing continuous monitoring solutions that provide real-time alerts in case of suspicious activities or security breaches.
Many of the controls in this category are borrowed from the COSO framework.
Security Controls in Practice
Let's visualize a revolutionary healthcare technology platform, ‘HealthSecure’. Dedicated to the impenetrable safeguarding of patient data, HealthSecure meticulously adheres to the stringent standards set by HIPAA, deploying advanced security protocols like robust firewalls, anti-virus software, and multi-factor authentication. Each access to a patient's health record requires a unique code sent to the user’s mobile device, ensuring that only authorized individuals can access sensitive health information. With a continuous commitment to security, HealthSecure routinely conducts comprehensive security assessments and penetration testing, reinforcing the system's defenses and proactively mitigating potential vulnerabilities to maintain the integrity of patients' confidential health information.
These controls ensure that systems are available for operation and are used as agreed upon by users and operating personnnel. This pivotal SOC 2 requirement nurtures reliability and user trust by ensuring consistent system performance and availability. Let’s dissect and explore the different facets of this principle to gain a deeper understanding of its implications and execution in organizational infrastructures.
System Redundancy: Organizations can cultivate system robustness by implementing redundant systems or components. This means that if a primary system fails, a backup is ready to take over, ensuring uninterrupted service.
Disaster Recovery: A meticulously crafted disaster recovery plan enables organizations to resume operations swiftly after a disruptive event, like a natural disaster or a system failure, by restoring lost data and ensuring the availability of essential services.

Automated Workflows: Utilizing automation in workflows can help in executing processes with enhanced precision and consistency, mitigating the risks of human error and augmenting operational integrity.
Processing Integrity-related Controls in Practice
Consider ‘HealthSync’, a fictional healthcare technology company specializing in electronic health records (EHR) and telemedicine services. HealthSync values the precision and immediacy of the health information and medical transactions processed through its system. Adhering rigorously to HIPAA regulations, and emphasizing the integrity and confidentiality of health data, they ensure that every piece of health information, whether it be patient records, prescription orders, or telemedicine consultations, is managed accurately and securely. For example, when a physician prescribes medication or updates a patient's health record, HealthSync’s system ensures that the accurate information is securely communicated and recorded, preserving the integrity and confidentiality of the patient's health information throughout the process.
Confidentiality and Privacy
The guidelines ensure that data is accessed only by authorized personnel, protecting information confidentiality and user privacy. At its heart, they mandate stringent controls ensuring that access to sensitive information is strictly regimented, safeguarding data against unauthorized access and ensuring its confidentiality and the privacy of its subjects. Let’s delve deeper into the intricacies of these guidelines to illuminate how they sculpt an organization's data security architecture.
Access Control Systems: Implementing robust access control systems, like Role-based Access Control (RBAC), ensures that only individuals with the necessary permissions can access specific sets of data, thereby maintaining the data’s confidentiality.
Authentication Protocols: Utilizing strong authentication protocols such as multi-factor authentication (MFA) fortifies access controls by adding an additional layer of security, ensuring that data access is limited to authorized personnel.
Encryption Technologies: Employing encryption technologies secures data both at rest and in transit, ensuring that even if unauthorized access occurs, the information remains protected and unintelligible.
Data Classification: Adopting data classification strategies helps in categorizing data based on sensitivity and confidentiality, ensuring that enhanced security measures are applied to more sensitive data sets.

Vendor Management: Evaluating and managing the security practices of third-party vendors who have access to organizational data is crucial in ensuring that external parties do not compromise data confidentiality.
User Privacy Policies: Establishing and maintaining clear user privacy policies ensures that user data is handled with respect and in alignment with privacy expectations and regulatory requirements.
Confidentiality and Privacy-related Controls in Practice
Imagine a healthcare application, ‘HealthGuard’. HealthGuard manages patient records, appointment scheduling, and consultation histories. Upholding the confidentiality and privacy principle of SOC 2, they ensure that sensitive patient information is shielded from unauthorized access. When a patient schedules an online consultation, the details of their appointment, including health concerns and doctor’s notes, are encrypted and stored securely. Access to this information is strictly regulated, ensuring that only authorized healthcare professionals can access specific patient data. HealthGuard also ensures that their data disposal practices maintain the confidentiality of the information, preventing unauthorized access or data breaches.
Preparing for Assessment
Firms will usually go through several stages before an SOC assessment report can be prepared by auditors. The stages include selection of an auditor and ensuring they are affliated with AICPA, selection of applicable controls for the organization and specifically for the systems involved in the assessment which is then followed by the design of these controls. This is then followed by the implementation or operation of any controls that were not in place already. This stage is then followed by evidence collection and finally the auditor publishes a report after review of the controls in place, some interviews with key personnel of the organization, as well as the actual evidence that was collected over a period of time.
SOC 2 principles stand as guardians of organizational integrity, playing pivotal roles in cultivating secure, reliable, and privacy-focused operational ecosystems. Through our imaginative journey including exploring fictitious companies like ‘‘HealthSecure’, ‘MediCloud’, ‘HealthSync’, and ‘HealthGuard’ and how they implement controls over systems and processes, we glimpse the applicative essence of the SOC 2 guidelines in various healthcare industry scenarios. In embracing these principles, organizations can foster a resilient operational environment, enhancing the reliability and security of their services in the eyes of their clients and partners. SOC standards stand as pillars of integrity, security, and privacy in the organizational landscape. Especially for developers and IT professionals in the realm of finance, technology, and cloud services, SOC familiarity isn’t just beneficial—it's imperative. Comprehending and integrating SOC guidelines can profoundly enhance operational robustness against threats and vulnerabilities.
This discussion aims to unveil the SOC standards, casting light on their significance in upholding the integrity, security, and privacy of organizational operations and data. As pillars of best practices, SOC standards bolster an organization’s resilience, trustworthiness, and operational excellence.
