CIS Implementation Groups—What Are They and How to Use Them

A trusted name in cybersecurity for many years, the Center for Internet Security (CIS) is renowned for providing comprehensive security frameworks and benchmarks widely adopted across industries.

One of their groundbreaking initiatives is the introduction of "Implementation Groups," or IGs, as part of the CIS Controls framework, which assist organizations of different sizes and capabilities implement CIS Controls effectively.

But what exactly are these Implementation Groups, and how can they be used? Let's take a closer look.

What Are CIS Implementation Groups?

CIS Implementation Groups organize the CIS Controls to make them more accessible and actionable for organizations with varying resources and cybersecurity maturity. Three Implementation Groups (IG1, IG2, and IG3) are classified based on the size of the organization, the complexity of their environment, and their risk profile.

  • IG1: Smaller organizations with limited resources and cybersecurity expertise.
  • IG2: Medium-sized organizations with moderate resources and some cybersecurity expertise.
  • IG3: Larger organizations with significant resources and established cybersecurity teams.

Each Implementation Group provides organizations with a prioritized set of controls and actions that they should focus on to improve their security posture. This hierarchical approach allows organizations to address the most critical risks first and progressively enhance their security posture as they move from IG1 to IG3.

How to Use CIS Implementation Groups

Using CIS Implementation Groups is a simple, step-by-step process that can be adapted to suit any organization's specific needs and capabilities. Here's how you can get started:

Identify Your Organization's ProfileThe first step is to determine which Implementation Group best suits your organization. Consider factors such as the size of your organization, the complexity of your IT environment, your current level of cybersecurity expertise, and your overall risk profile. This will help you choose the right Implementation Group to start with.
Assess Your Current Security Posture
Before implementing any CIS Controls, it's essential to evaluate your current security posture. Identify your organization's strengths and weaknesses in cybersecurity. Conduct a risk assessment to identify your organization's potential threats and vulnerabilities, providing a better understanding of the security measures you must prioritize.
Implement the Controls

  1. Identify Your Organization's Profile: The first step is to determine which Implementation Group best suits your organization. Consider factors such as the size of your organization, the complexity of your IT environment, your current level of cybersecurity expertise, and your overall risk profile.
  2. Assess Your Current Security Posture: Before implementing CIS Controls, it's essential to evaluate your current security posture. Identify your organization's strengths and weaknesses, conduct a risk assessment to identify your organization's potential threats and vulnerabilities, which will provide a better understanding of the security measures you should prioritize.
  3. Implement the Controls: Start implementing the relevant CIS Controls  based on your chosen Implementation Group. Focusing on the controls within your Implementation Group first is crucial before moving on to the next group. This will help build a strong security foundation and makes tackling more complex controls easier.
  4. Monitor and Review: After implementing the controls, continuously monitor your IT environment for signs of suspicious activity or security incidents. Review the effectiveness of your implemented controls and make adjustments as needed—keeping in mind that because the threat landscape is constantly evolving, additional updates may be necessary down the road.
  5. Progress to the Next Implementation Group: As your organization grows and your security posture improves, consider progressing to the next Implementation Group, which will help you address more complex threats and enhance your security posture. 

Benefits of Using CIS Implementation Groups

CIS Implementation Groups offer several benefits that improve your security posture:

  • Scalability: The tiered approach allows organizations of all sizes to benefit from the CIS Controls framework. Whether you're a small business or a large enterprise, there's an Implementation Group that suits your needs.
  • Prioritization: Implementation Groups help organizations focus on the most critical controls first, reducing the risk of overwhelming cybersecurity teams.
  • Adaptability: The flexibility of the Implementation Groups allows you to progress at your own pace, moving to the next group as capabilities improve.
  • Effectiveness: By implementing controls based on your organization's risk profile and resources, organizations can achieve a more robust security posture that effectively addresses your unique threats and vulnerabilities.

Conclusion

CIS Implementation Groups provide a valuable framework for organizations looking to improve security posture. By identifying your organization's profile, assessing your current security posture, implementing the relevant controls, and continually monitoring and reviewing your efforts, you can leverage the power of CIS Implementation Groups to achieve a robust and resilient security posture.

In 20222, Sicura and CIS announced a partnership for integrated cybersecurity remediation to deliver actionable security insight and improved cyber hygiene.
