Information security is a reason for concern for all organizations, including those that outsource key business operation to third-party vendors (e.g., SaaS, cloud-computing providers). Rightfully so, since mishandled data—especially by application and network security providers—can leave enterprises vulnerable to attacks, such as data theft, extortion and malware installation.
SOC 2 is an auditing procedure that ensures your service providers securely manage your data to protect the interests of your organization and the privacy of its clients. For security-conscious businesses, SOC 2 compliance is a minimal requirement when considering a SaaS provider.
There are two types of SOC reports:
- Type I describes a vendor’s systems and whether their design is suitable to meet relevant trust principles at single point of time
- Type II details the operational effectiveness of those systems over a period
SOC 2 certification
SOC 2 certification is issued by outside auditors. They assess the extent to which a vendor complies with one or more of the five trust principles based on the systems and processes in place.
Trust principles are broken down as follows:
1. Security
- The security principle refers to protection of system resources against unauthorized access.
- Access controls help prevent potential system abuse, theft or unauthorized removal of data, misuse of software, and improper alteration or disclosure of information.
- IT security tools such as network and web application firewalls (WAFs), two factor authentication and intrusion detection are useful in preventing security breaches that can lead to unauthorized access of systems and data.
2. Availability
- The availability principle refers to the accessibility of the system, products or services as stipulated by a contract or service level agreement (SLA).
- As such, the minimum acceptable performance level for system availability is set by both parties.
- Monitoring network performance and availability, failover and security incident handling are critical in this context.
3. Processing integrity
- The processing integrity principle addresses whether or not a system achieves its purpose (i.e., delivers the right data at the right price at the right time).
- Accordingly, data processing must be complete, valid, accurate, timely and authorized.
- Monitoring of data processing, coupled with quality assurance procedures, can help ensure processing integrity.
4. Confidentiality
- Data is considered confidential if its access and disclosure is restricted to a specified set of persons or organizations. Examples may include data intended only for company personnel, as well as business plans, intellectual property, internal price lists and other types of sensitive financial information.
- Encryption is an important control for protecting confidentiality during transmission.
- Network and application firewalls, together with rigorous access controls, can be used to safeguard information being processed or stored on computer systems.
5. Privacy
- The privacy principle addresses the system’s collection, use, retention, disclosure and disposal of personal information in conformity with an organization’s privacy notice, as well as with criteria set forth in the AICPA’s generally accepted privacy principles (GAPP).
- Personal identifiable information (PII) refers to details that can distinguish an individual (e.g., name, address, Social Security number).
- Some personal data related to health, race, sexuality and religion is also considered sensitive and generally requires an extra level of protection.
- Controls must be put in place to protect all PII from unauthorized access.
