Strengthening Cybersecurity with CIS Controls: A Guide for Managed Service Providers

In an era where cyber threats are becoming increasingly sophisticated, protecting an organization from cybersecurity risks is a paramount concern for IT service providers. Managed Service Providers (MSPs) play a crucial role in safeguarding their clients against cyberattacks, and one of the most effective ways to achieve this is by implementing a robust cybersecurity framework. Among the various frameworks available, the Center for Internet Security (CIS) Controls stand out as practical and effective tools for MSPs to enhance their clients’ cybersecurity posture.

Understanding CIS Controls

CIS Controls are a set of prescriptive, prioritized best practices designed to help organizations improve their cybersecurity defenses. Unlike frameworks such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework, which is government-driven, CIS Controls are developed through collaboration across various sectors, including government, academia, and industry. This broad input ensures that the controls address common cybersecurity threats and distill key security concepts into actionable measures.

The Importance of CIS Controls

Adopting CIS Controls is essential for maintaining a strong cybersecurity posture. By leveraging the collective knowledge of the cybersecurity community, organizations can build a robust layer of defense against potential threats. The framework not only alleviates the burden of creating a comprehensive cybersecurity program from scratch but also covers critical aspects of the cyber landscape, including:

• Achieving Higher Standards of Cyber Hygiene: Implementing CIS Controls helps organizations establish and maintain effective cybersecurity practices.

• Gaining Insight into the Attack Surface: Organizations can better understand their vulnerabilities and exposure to threats.

• Proactive Remediation: The framework encourages organizations to undertake thoughtful and proactive measures to address potential security issues.

• Resilience in the Face of Incidents: By preparing for incidents or breaches, organizations can minimize damage and recover more effectively.

Benefits of Implementing CIS Controls for Clients

For MSPs, helping clients adopt the CIS framework offers numerous advantages, particularly for small and mid-sized organizations that may have limited resources. Some key benefits include:

• Prioritization: CIS Controls provide a clear list of security actions, allowing organizations to focus on the most critical measures first.

• Risk Reduction: By addressing common attack vectors and managing assets effectively, organizations can significantly reduce their risk exposure.

• Standardization: The framework establishes a common language and baseline for security practices across different sectors within an organization.

• Resource Optimization: CIS Controls enable organizations to allocate cybersecurity resources more effectively, ensuring that critical areas receive the necessary attention.

• Scalability: The inclusion of Implementation Groups (IGs) allows organizations to adopt the Controls incrementally, making it easier for them to implement effective cybersecurity measures.

• Comprehensive Coverage: The Controls span various cybersecurity domains, including asset management, vulnerability management, access control, and incident response.

• Alignment with Industry Standards: CIS Controls align with various regulatory frameworks, such as NIST, ISO, and GDPR, facilitating compliance and adherence to industry best practices.

Challenges of Deploying CIS Controls

While the benefits of implementing CIS Controls are clear, organizations may face several challenges in the process. One significant challenge is the evolving tactics employed by cybercriminals, which necessitates a professional and up-to-date cybersecurity team. Additionally, budget constraints can hinder the implementation of CIS Controls, as developing a comprehensive cybersecurity strategy often requires significant investment.

To successfully navigate these challenges, organizations must develop a reliable strategy and consider partnering with experienced third-party teams or hiring in-house cybersecurity professionals. This approach ensures that the necessary expertise and resources are in place to implement CIS Controls effectively.

Utilizing an MSP for CIS Controls

The CIS has released guidance to assist enterprises in establishing basic cyber hygiene through the use of a managed service provider. The guide, titled Establishing Basic Cyber Hygiene Controls Through a Managed Service Provider, is particularly beneficial for small- and medium-sized enterprises seeking to ensure that their service provider meets essential cybersecurity standards.

CIS Controls utilize Implementation Groups to help organizations prioritize their cybersecurity efforts. By understanding which Implementation Group and CIS Controls align with their needs, organizations can effectively incorporate an MSP into their cybersecurity strategy. The guide also provides a baseline of questions to ask MSPs, such as:

• What type of controls are implemented at the MSP for their own security?
• Which CIS Controls are implemented by the MSP on behalf of their clients?

For small and medium enterprises, the 43 Safeguards in CIS Controls IG1 offer guidance for establishing basic cyber hygiene. This level of support can be invaluable, especially when working with an MSP.

Conclusion

In the face of ever-evolving cybersecurity threats, adopting a structured approach to cybersecurity is essential for organizations of all sizes. By implementing CIS Controls, MSPs can help their clients enhance their cybersecurity posture, reduce risk, and achieve compliance with industry standards. While challenges may arise during the implementation process, partnering with experienced cybersecurity professionals can pave the way for a more secure future.
