The rapidly evolving software security landscape is quickly becoming a critical concern for all industries. Cyberattacks are on the rise and software systems that were not considered a security risk in the past now need to incorporate software security measures to ensure consumer safety, privacy, and reliability. For the commercial trucking industry, software security is a big concern because the software systems connect to internal and external environments which creates a high level of cyber-threat exposure. In the commercial trucking industry, the risk of unsecure software code can lead to consequences that not only affect the organization but also the supply chain in whole. This study addressed a gap in the literature by answering the following research question: How do commercial trucking firms incorporate cybersecurity measures into their software development process? A qualitative exploratory case study methodology was selected, and semi-structured interviews were conducted with information technology professionals who work on software development teams that incorporate secure coding practices throughout the software development process. The population for this study consisted of information technology professionals working at a commercial trucking organization in the Southeastern region of the United States. Inductive analysis was used to identify emerging themes within the data. Themes that emerged highlighted the (a) secure code training should be provided to all software development team members, (b) software development teams need access to secure development tools to quickly identify and remediate source code flaws, and (c) integrating secure coding measures throughout the software development lifecycle is everyone’s responsibility.
