Abstract

The National Transportation Safety Board is charged with investigating transportation-related accidents and incidents in the aviation, railroad, highway, marine and pipeline infrastructure. The increasing integration of traditional information technology systems with operational technology systems increases the cyber vulnerabilities and risk. National Transportation Safety Board investigations require trustworthy data to determine accident and incident causes and remedies. This chapter explores the requirements for trust in the critical transportation infrastructure due to operational technology and information technology integration. The focus is on internal aircraft systems and their data in accident investigations. While commercial avionics systems employ very reliable serial bus architectures, these systems and their components were not designed with cyber security in mind. Cyber state mechanisms such as software …
