Framework: The Center for Internet Security (CIS) Top 18 Controls

Safeguard 1.2 emphasizes the importance of identifying and responding to unauthorized assets that appear within the enterprise environment. Unapproved devices can range from rogue wireless access points and personal laptops to forgotten test systems and decommissioned servers still connected to the network. Each represents a potential backdoor for attackers. The safeguard requires organizations to...

Safeguard 1.1 directs organizations to establish and maintain a detailed inventory of all enterprise assets capable of storing or processing data. This includes not just traditional endpoints and servers but also virtual machines, network appliances, IoT devices, and cloud instances. The goal is to produce a living, authoritative record that accurately reflects the organization’s digital environme...

Asset management is the cornerstone of every effective cybersecurity program because you cannot protect what you do not know exists. Control 1 of the CIS framework—Inventory and Control of Enterprise Assets—focuses on developing a precise, continually updated record of all devices, systems, and components connected to the enterprise environment. These include desktops, laptops, servers, network de...

As cybersecurity practices mature, professionals encounter more specialized terminology that connects operational tactics to governance and technical architecture. Multi-Factor Authentication (MFA) enhances login security by requiring two or more proofs of identity—something you know, have, or are. Encryption transforms readable data into a coded form to protect its confidentiality both in transit...

Understanding cybersecurity language is fundamental to applying the CIS Controls effectively. Many terms describe foundational components of systems, threats, and defenses that appear throughout the framework. Asset refers to any device, software, or data that the organization must protect, while enterprise assets include servers, workstations, and IoT devices that store or process information. Vu...

In the context of the CIS framework, a “control” is a broad security domain representing a strategic objective, while a “safeguard” refers to a specific, actionable measure within that control. Each of the 18 CIS Controls addresses a distinct functional area—such as asset management, access control, or data protection—and defines its importance in defending against real-world attacks. Safeguards,...

Implementing the CIS 18 effectively begins with understanding how the Controls fit into your organization’s governance, risk management, and compliance efforts. The framework is intentionally flexible, allowing it to integrate seamlessly with existing standards and policies rather than replace them. The first step is conducting a baseline assessment against each Control to determine your organizat...

The CIS Critical Security Controls, often referred to as the CIS 18, represent a prioritized and prescriptive set of cybersecurity best practices designed to help organizations defend against the most pervasive and dangerous cyberattacks. Developed and maintained by the Center for Internet Security (CIS), these controls are informed by real-world threat data and expert consensus across government,...
