Across the landscape of IT, Open Source Software (OSS) is pervasive and ubiquitous. From the cloud and web to data centers; from the desktop to mobile devices; and across a range of embedded and IoT applications, OSS commands an ever-increasing, dominant share of the system software stack and provides equally substantial swathes of enabling application middleware, applications themselves, and tooling. While rapid adoption of OSS demonstrably offers a range of advantages, the community development model presents developers, integrators and deployers with a set of accompanying challenges related to security, operational, and legal risk. Historically, foremost among these concerns stood license compliance and IP protection; however, with recetnt highly publicized threats to OSS, security has joined these concerns and today dominates the OSS adoption conversation. This presentation will explore the role of and requirements for secure development of and deployment with OSS.
