1. Module Description
The Introduction to Cybersecurity for Transportation Agencies module will provide an overview of key topics relating to cybersecurity for transportation agencies.
The module will first discuss the need for cybersecurity including typical threats that transportation agencies face to their centers, field equipment, and communications. Next, the module will introduce the NIST Cybersecurity Framework which enables organizations to apply the principles and best practices of risk management to improving security and resilience. Then the module will discuss how to apply the Framework to a transportation agency. Finally, the module will look at resources that are available to agencies for sharing information about cybersecurity threats and incidents. Additional resources on cybersecurity for the roadway transportation infrastructure will be identified.

3.1. Critical Infrastructure
The Cybersecurity and Infrastructure Security Agency (CISA) was established November 16th, 2018. It is a standalone United States federal agency, an operational component under Department of Homeland Security (DHS) oversight. Its activities are a continuation of the National Protection and Programs Directorate (NPPD). NPPD’s goal was to advance the Department’s national security mission by reducing and eliminating threats to U.S. critical physical and cyber infrastructure. Critical infrastructure describes the physical and cyber systems and assets that are so vital to the United States that their incapacity or destruction would have a debilitating impact on our physical or economic security or public health or safety. CISA has identified 16 critical infrastructures as discussed below.
The Department of Homeland Security is designated as the Sector-Specific Agency for the Chemical Sector.

3.6. NIST Cybersecurity Framework
Learning objectives 2 and 3 focus on information from the NIST Cybersecurity Framework which can be found on the NIST website at:
The following overview is taken directly from the NIST Cybersecurity Framework document (National Institute of Standards and Technology (NIST) Cybersecurity Framework Version 1.1).
"The Framework is a risk-based approach to managing cybersecurity risk, and is composed of three parts: the Framework Core, the Framework Implementation Tiers, and the Framework Profiles. Each Framework component reinforces the connection between business/mission drivers and cybersecurity activities. These components are explained below.
The Framework Core is composed of a set of categories, subcategories and informative references within each of five basic functions. The Appendix provides a table that shows these functions, categories, and subcategories exactly as described in the Framework Document.
The descriptions above are specific sections of standards, guidelines, and practices common among critical infrastructure sectors that illustrate a method to achieve the outcomes associated with each subcategory. The references presented in the Framework Core are illustrative and not exhaustive. They are based upon cross-sector guidance most frequently referenced during the Framework development process." The following are the informative references from the framework:
