The Cyber Security Evaluation Tool (CSET®) is a Department of Homeland Security (DHS) product that assists organizations in protecting their key national cyber assets. It was developed under the direction of the DHS Industrial Control System Cyber Emergency Response Team (ICS-CERT) by cybersecurity experts and with assistance from the National Institute of Standards and Technology (NIST). This tool provides users with a systematic and repeatable approach for assessing the security posture of their cyber systems and networks. It includes both high-level and detailed questions related to all industrial control and IT systems.
CSET is a desktop software tool that guides users through a step-by-step process to assess their control system and information technology network security practices against recognized industry standards. The output from CSET is a prioritized list of recommendations for improving the cybersecurity posture of the organization's enterprise and industrial control cyber systems. The tool derives the recommendations from a database of cybersecurity standards, guidelines, and practices. Each recommendation is linked to a set of actions that can be applied to enhance cybersecurity controls.
CSET has been designed for easy installation and use on a stand-alone laptop or workstation. It incorporates a variety of available standards from organizations such as NIST, North American Electric Reliability Corporation (NERC), Transportation Security Administration (TSA), U.S. Department of Defense (DoD), and others. When the tool user selects one or more of the standards, CSET will open a set of questions to be answered. The answers to these questions will be compared against a selected security assurance level, and a detailed report will be generated to show areas for potential improvement. CSET provides an excellent means to perform a self-assessment of the security posture of your control system environment.
