Learn to solve the cybersecurity "Goldilocks problem" of setting optimal security thresholds through algorithmic approaches in this 42-minute conference talk from The Diana Initiative 2025. Discover how to move beyond arbitrary risk scores and gut-feel decisions to implement data-driven methodologies for application classification and security control tiering. Explore practical frameworks using spreadsheet formulas for structured decision-making and Python runbooks for automated application tiering that help identify and classify applications based on security impact and business context. Master techniques to dynamically define security thresholds that avoid both overlooking critical applications and creating unnecessary overhead for security teams. Gain actionable insights for implementing scalable, defensible security control decisions that satisfy audit committees and stakeholders with clear reasoning. Presented by Rachana Kamat, Senior Security Engineer at Samsara, this session targets security engineers, risk analysts, data analysts, and data scientists seeking to justify control decisions through structured, algorithmic methodologies rather than hunches or basic averages.
