The talk introduces the concept of Shift Down Security, an approach designed to enhance security throughout the entire application lifecycle, particularly during deployment and runtime. Building upon Shift Left Security, which focuses on identifying vulnerabilities early in the development process, Shift Down Security focuses on continuous monitoring, policy enforcement, and real-time threat response during and after deployment. It ensures the security of cloud infrastructure, runtime environments, and third-party dependencies, addressing late-emerging risks and mitigating misconfigurations. This approach empowers platform engineering teams to automate security, improve observability, and ensure operational resilience without disrupting developer workflows. By combining Shift Down Security with tools like CNAPP, organizations can create a holistic, proactive security strategy.
