The Cyber Security Evaluation Tool (CSET®) is a free stand-alone desktop application that systematically guides asset owners and operators through evaluating operational and information technology. The Department of Homeland (DHS) Cybersecurity and Infrastructure Security Agency (CISA) offers the CSET® download at no cost. The benefits of CSET® include the:

  • Creation of infrastructure security assessments through systematic, disciplined, and repeatable methods,
  • Generation of baseline reports that can help determine trends by comparing multiple assessments,
  • Customization of System Security Plans based upon assessment results that allow organizations to qualify their cybersecurity posture; and
  • Construction of network diagrams that users can prepare from scratch or through a pre-built template diagram
  • Support data export and import feature via JSON
  • Create custom assessments via the Module Builder feature
  • New Cyber Performance Goal Assessment that is designed to help Critical infrastructure partners

Within CSET®, there is a specific module, the Land Mobile Radio (LMR) Rapid Assessment module, designed to assist public safety LMR system owners in assessing key aspects of an LMR system’s cybersecurity status. This module is based on a subset of The National Institute of Standards and Technology (NIST) Special Publication (SP) 800-53, “Security and Privacy Controls for Information Systems and Organizations” controls. The module guides LMR system owners/operators through control questions so that an LMR system owner/operator can gain insights into their LMR system's cybersecurity status and identify improvement measures.
