CIS Control 15 Explained: Service Provider Management

CIS Control 15 focuses on establishing and maintaining a robust process for evaluating and managing service providers who handle sensitive data or critical IT operations. The goal is to ensure these providers uphold the availability, confidentiality, and integrity of your organization's information.

The Importance of Control 15

Modern organizations increasingly rely on third-party service providers for essential functions such as data processing, operations, and cybersecurity. However, breaches at these providers can disrupt operations and expose sensitive data. Managing third-party risks is therefore critical to maintaining a secure business environment and meeting compliance requirements.

Implementation Groups (IGs)

CIS Controls use Implementation Groups (IGs) to prioritize safeguards based on an organization's cybersecurity maturity:

Note: Safeguards required for IG1 are also required for IG2 and IG3.

The Safeguards of Control 15

There are seven safeguards in CIS Control 15. Each is mapped to a NIST CSF Function and an Implementation Group:

Safeguard Number Safeguard Title NIST Security Function Starting Implementation Group
15.1 Establish and Maintain an Inventory of Service Providers Identify IG1
15.2 Establish and Maintain a Service Provider Management Policy Govern IG2
15.3 Classify Service Providers Govern IG2
15.4 Ensure Service Provider Contracts Include Security Requirements Govern IG2
15.5 Assess Service Providers Govern IG3
15.6 Monitor Service Providers Govern IG3
15.7 Securely Decommission Service Providers Protect IG3

CIS Control 15 Explained: Service Provider Management

CIS Control 15 involves service provider management. That means to establish a process to evaluate service providers who hold sensitive data or are responsible for critical IT operations and ensure that they are protecting the availability, confidentiality and integrity of your organization’s information appropriately.

The Importance of Control 15

Many businesses today rely on third-party service providers for essential functions, such as data processing, operations and cybersecurity management. Breaches at these providers can lead to significant consequences for enterprises. Such incidents can disrupt operations and, in some cases, allow attackers to compromise data on a business’s systems by exploiting access through these providers. Therefore, managing third-party risks is critical to maintaining a secure business environment.

Implementation Groups (IGs)

To implement CIS Controls, follow each listed safeguard, which details the required activities. Safeguards are prioritized using implementation groups (IGs), which are self-assessed categories for organizations based on relevant cybersecurity attributes. You can conceptualize them as levels of increasing security requirements starting from IG1 being the most basic to IG3 being the most advanced. The higher level groups are included in the lower ones.

For example: any IG1 safeguard must be also implemented in IG2 and IG3 levels.
