Comparison of ISO27001 and SOC2 Compliances
ISO 27001 and SOC 2 COMPARISON
There is an increased need for service organizations to provide assurance, trust and transparency over their controls to enterprises that outsource functions or processes to them (service organizations).
SOC2 report – Relates to assurance on IT controls.
ISO 27001 enables organisations to implement an ISMS (Information Security Management System) framework.
This framework includes detailed documentation of IT policy and procedures.
Once an organisation is compliant to ISO 27001 standard, it is assured of having a strong foundation of Information Security principles that are designed and implemented.
CONTROL EFFETIVENESS (DESIGN AND OPERATION)
INFORMATION SECURTIY MANAGEMENT SYSTEM (ISMS)
The framework can then be used to build upon other regulatory or client requirements such as SOC2.
Why SOC 2?
The ISO certification is a proof of organisation’s ability to maintain an effective ISMS at a certain point in time. (Example — It is comparable to getting a house inspected. The house may be very clean on the day of inspection but once the inspection is complete, there is no real way to verify the cleanliness standard of the house).
Due to this lack of long-term assurance, many organisations go for a Service Organisation Control (SOC) attestation in order to demonstrate their ability to maintain an effective IT security control environment (as opposed to simply being able to execute them).
SOC 2 report focuses on the effectiveness of the design and operation of their controls (over the system through which the services are delivered) that are relevant to the systems’ security, availability or processing integrity, or it may cover the confidentiality or privacy of the information processed for user entities
AREA SOC 2 ISO 27001
Purpose Assist service organization management in reporting to customers that it has met trust service principles and criteria that ensures that the system is protected. Outlines the requirements for constructing a risk-based framework to initiate, implement, maintain, and manage information security within an organization.
Focused on Systems ( information systems policy, procedures, system security, and change management) ISMS (information security risk that can apply to human resources, asset management, supplier relationships, etc.)
Certification/Attestation Attestation –
Includes details of the company background, services provided, and the system (infrastructure, procedures, people, data, and applications) within the scope of the assessment.
The attestation report includes details of controls that meet the applicable Trust Services Criteria. Certification – which includes deliverable that outlines the organization’s conformance to the standard set of requirements.
Period covered Point in time (in the case of a Type 1 report —- This means that the report only provides information on controls that are in place (designed) at a specific point in time and not whether the controls are operating on a continuous basis throughout a specified time period.) or period of time (in the case of a Type 2 report). Point in time
Framework 7 common criteria’s + 4 additional criteria’s Control ranging from A.5 to A.18
CAN ISO 27001 AND SOC 2 IMPLEMENTED AT THE SAME TIME?
YES, both can be implemented as it saves time/cost and effort.
The point to consider here is the requirements for SOC 2 can be treated as a input to implement ISMS framework.
ISO 27001 is an excellent guide for implementing a security program (or practices) at an organisation.
SOC2 best use is to provide an organisation with a way to demonstrate that security practices are in place and operating effectively. An organisation may have a need for both.
