Making Available Information Now to Strengthen Trust and Resilience and Enhance Enterprise Technology Cybersecurity Act of 2017 or the MAIN STREET Cybersecurity Act of 2017

This bill amends the National Institute of Standards and Technology Act to require the National Institute of Standards and Technology (NIST) to consider small businesses when it facilitates and supports the development of voluntary, consensus-based, industry-led guidelines and procedures to cost-effectively reduce cyber risks to critical infrastructure.

NIST must disseminate, and publish on its website, standard and method resources that small business may use voluntarily to help reduce their cybersecurity risks. The resources must be: (1) technology-neutral, (2) based on international standards to the extent possible, (3) able to vary with the nature and size of the implementing small business and the sensitivity of the data collected or stored on the information systems, and (4) consistent with the national cybersecurity awareness and education program under the Cybersecurity Enhancement Act of 2014.

Other federal agencies that NIST considers appropriate must also publish the resources on their own websites.
