Report Description

This report presents the results of our audit of the Security of Electric Vehicle Charging Stations.

Our objective was to assess the security of the Postal Service’s EV charging stations. We contracted with a provider to evaluate the technical, communication, and data security controls of one charging station from each of the three vendors. We also conducted site visits to three Sorting and Delivery Centers to review physical security for safeguarding EV charging stations and evaluated policies and best practices for contingency planning.
