With the ever-present threat of data breaches and cyberattacks, organizations must make cyber security a top priority. One of the most systematic and effective approaches is implementing the CIS (Center for Internet Security) Framework. By understanding and applying the CIS Framework you can significantly enhance your cybersecurity posture and protect your organization.
The CIS Framework refers to a set of 20 prioritized, internationally recognized best practices for cyber defense. They were developed by leading IT security experts from around the world. The core principle behind the CIS framework is to provide organizations with a clear road map on how to secure their system from the most pervasive cyber-attacks.
Using the CIS Framework offers several advantages. Firstly, it focuses on a set of actions that, when implemented, can prevent up to 85% of the most common cyber threats. Secondly, the CIS Framework is designed to be continuously updated, which helps organizations keep pace with evolving threats. Lastly, the CIS Framework not only provides guidance on what controls to implement but also offers steps to establish those controls.
The CIS Framework is divided into 20 key controls. These are grouped into three categories: Basic (1-6), Foundational (7-16), and Organizational (17-20). The Basic Controls are the essential actions that every organization must do to establish a cybersecurity program. The Foundational Controls contain various technical best practices providing clear security benefits. The Organizational Controls focus on the people and processes involved in cybersecurity.
The Basic controls aim to lay down the foundation upon which a cybersecurity program can be developed. The six controls in this category include: Inventory and Control of Hardware Assets, Inventory and Control of Software Assets, Continuous Vulnerability Management, Controlled Use of Administrative Privileges, Secure Configuration for Hardware and Software on Mobile Devices, Laptops, Workstations, and Servers, and Maintenance, Monitoring, and Analysis of Audit Logs.
The Foundational Controls build on the basic controls to provide deeper and more complex security measures. These controls focus on areas like Email and Web Browser Protections, Malware Defenses, Limitation and Control of Network Ports, Data Protection, Controlled Access Based on the Need to Know, and more.
The Organizational controls focus on broader organizational processes around security. These include areas like Incident response and Management, Penetration Tests and Red Team Exercises, and more.
When starting to implement the CIS Framework, begin with the first six basic controls, these are considered cyber hygiene. With these in place, an organization will have a solid foundation to build a comprehensive cybersecurity program. Next, continue with the Foundational and Organizational controls. Though different businesses may prioritize some controls differently depending on their circumstances, the CIS controls are intended to be implemented in their respective order as it forms a layered defense strategy.
The implementation of the CIS Framework, though beneficial, is not without challenges. These can include resource limitation, lack of technical expertise, and a lack of a strong leadership commitment. Matching the right set of technologies to the controls can also be a challenge, as well as the continuous effort involved in maintaining and updating these controls.
There are several best practice methods when implementing the CIS Framework. It's crucial to fully commit to the process, remembering that perfecting cybersecurity defenses is an ongoing process, not a one-time task. Organizational leadership must prioritize cyber defense and foster a culture of security. It is also important to leverage technology to automate and simplify the implementation of the controls where possible.
In conclusion, implementing the CIS Framework is a powerful step towards instituting a strong and effective cybersecurity program. The benefits far outweigh the challenges, offering a robust and dynamic defense strategy against cyber threats. Creating awareness about the CIS Framework and understanding how to apply it to achieve optimal results is crucial. This comprehensive guide assists in navigating the CIS Framework, invoking its concepts into your cybersecurity culture and keeping your organization secure in the struggling world of cyber threats.
