The Cybersecurity Infrastructure Security Agency (CISA) and the Idaho National Laboratory (INL) develop the Cyber Security Evaluation Tool (CSET®) for asset owners with the primary objective of reducing the risk to the nation’s critical infrastructure. Control systems are defined as electronic devices that control physical processes and as such, are a crucial element in the protection of our nation’s infrastructure.
CSET is a free software tool that guides users through a step-by-step process to collect facility-specific information addressing topics such as hardware, software, administrative policies, and user obligations. It then compares that information to relevant security standards and regulations, assesses overall compliance, and provides appropriate recommendations for improving cybersecurity posture. The tool pulls its recommendations from a collection of the best available cybersecurity standards, guidelines, and practices. Where appropriate, recommendations are linked to a set of actions that can be applied to enhance cybersecurity controls.
CSET provides the following:
• A framework for analyzing cybersecurity vulnerabilities associated with an organization’s overall industrial control system (ICS) and information technology (IT) architecture.
• A consistent and technically sound methodology to identify, analyze, and communicate to security professionals the various vulnerabilities and consequences that may be exploited by cyber means.
• The means for the user to document a process for identifying cybersecurity vulnerabilities.
• Suggested methods to evaluate options for improvement based on existing standards and recommended practices.
View the CSET Overview and CSET Detailed Video to learn more about CSET and how to use the software.
Local installers ("standalone") are available as well as binaries for creating enterprise installations.
CSET operates on Windows laptops or desktop computers and can also be configured for a client-server architecture.
