Understanding The Center for Internet Security's (CIS) Top 18 security controls is not just crucial for IT experts, but for anyone interested in effective cybersecurity strategy. These controls establish the basis of successful and solid cybersecurity defense. They are universally recognized as being among the most effective strategies to mitigate potential cyber risks. In this blog post, we'll be delving deep into the world of the CIS Top 18 to help you understand and subsequently implement them.
What Is the CIS Top 18?
Let's start by defining our key phrase. The CIS Top 18 is a set of action-oriented security controls that provide a strategic plan to deal with the risks and vulnerabilities within an organization’s information systems environment. This list has been developed in accordance with specific threat data and integral cybersecurity expertise contributed by organizations across the globe.
Diving into the CIS Top 18 Controls
For convenience, the controls have been classified into three distinct categories. This includes Basic (1-6), Foundational (7-16), and Organizational (17-18).
The basic controls encompass the crucial and most basic steps to be taken by organizations that desire to secure their systems. These controls cover aspects such as Inventory and Control of Hardware Assets, Software Assets, Continuous Vulnerability Management, Controlled Use of Administrative Privileges, and Secure Configuration for Hardware and Software on Mobile Devices, Laptops, Workstations, and Servers.
The foundational controls comprise of a wide range of procedures and mechanisms that aid in a detailed and complex defense. These entail the likes of Maintenance, Monitoring, and Analysis of Audit Logs, Email and Web Browser Protections, Malware Defenses, Limitation and Control of Network Ports, Wireless Access Control, and Data Recovery Capabilities amongst others.
The organizational controls include processes like the Implementation of a Security Awareness and Training Program. This encourages the growth of cybersecurity awareness among employees, therefore creating a solid security environment.
Admittedly, the concept may sound quite complicated, but with proper planning and execution, these controls can be implemented with relative ease and slightly less hassle.
Implementing the CIS Top 18 Controls
Although at first glance, the implementation of the CIS Top 18 may seem like an immense task, breaking down the control and adopting a phased approach can significantly ease the process. Begin with the Basic Controls, before gradually moving on to the Foundational and eventually the Organizational Controls. It's also crucial to remember that while these controls are most effective when all implemented, even adopting a few can significantly improve an organization's cyber defenses.
To begin with, scrutinize the existing system controls, determine the current level of cybersecurity and identify potential areas of vulnerability. In doing so, possible attack vectors can be detected, and an organization can commence implementing the CIS Top 18, starting with the Basic, then Foundational, and finally the Organizational Controls. Each control will further bolster the defenses of the network and keep the infrastructure secure from potential cyber threats.
In terms of the specifics involved in the implementation of each individual control, the Center for Internet Security provides extensive guidance on their official website. By adhering to the guidelines provided, organizations can steadily and assuredly build a robust and secure defense system that adheres to the global cybersecurity standards defined by the CIS Top 18.
Understanding and implementing the CIS Top 18 is pivotal for any effective cybersecurity strategy. These strategic controls offer a means for organizations to protect their systems against an increasingly hostile and complex digital environment. As such, it is incumbent upon modern organizations to optimize their defense strategies by utilizing these non-negotiable cyber hygiene measures that make up the CIS Top 18. Despite the potentially overwhelming scale of the task, proper planning, phased execution and continuous revision of implemented controls can significantly ease this process while ensuring optimal cyber defense.
