How ISO 27001 Helps in Managing Third-Party Risk

In today’s connected world, businesses often rely on third-party vendors and partners. While these relationships can boost efficiency and spark innovation, they also bring significant risks, especially when it comes to data security and compliance. Implementing ISO 27001, the international standard for information security management systems (ISMS), is a powerful way to effectively manage these third-party risks.

Understanding ISO 27001 and Its Structure

ISO 27001 helps organizations set up, maintain, and improve their information security program, otherwise known as the ISMS. The clauses and annex controls work together to create a solid framework for managing risks.

The Role of Clauses and Annex Controls

The clauses of ISO 27001 outline what you need to do to create an ISMS, covering everything from risk assessments to security objectives and management frameworks. On the other hand, the annex controls—found in Annex A—give you specific guidelines for putting security measures into practice.

ISO 27001 utilizes a risk-based approach. This allows organizations to customize their security practices to fit their specific situations, which is especially important when dealing with third-party risks.

Relevant Annex Control: A5.19 - information, security, and supplier relationships and a 5.20, addressing information security within supplier agreements.

This control helps ensure that the risks tied to supplier relationships are properly managed.

Key Requirements

Risk Assessment: Organizations need to assess the risks linked to their suppliers and see how these risks impact overall information security. This isn’t a one-time task—it should be done regularly, especially if there are changes in the supplier relationship or the overall threat landscape.
Information Security in Supplier Agreements: It’s important to clearly outline information security requirements in agreements with suppliers. This means specifying what security measures suppliers must have in place to protect sensitive data.

Monitoring and Review: Regularly checking in on how suppliers are performing in terms of information security is essential. Organizations must ensure that suppliers are sticking to agreed-upon security practices and address any issues quickly.
