Traditional computer system deployments involved a 'Design System' first and then 'Design Security' approach to meet application user demands. This approach is ill-suited to deploy today's increasingly cloud-based system architectures that are being adopted by industry applications with very large user bases such as media, manufacturing, healthcare and energy. Infrastructure engineers and application developers are now forced to take a parallel approach of 'Design Security' along with 'Design System'. While doing so, a major challenge for them is to address 'usable cybersecurity' in their design efforts in order to systematically study the synergies as well as constraints in balancing resilience (security) and user experience (performance/usability). In this talk, foundations for usable cybersecurity will be presented considering the CIA triad (Confidentiality, Integrity and Availability) requirements. Following this, usable cybersecurity case studies relating to access control, anomaly detection and cyber defense will be presented in the context of cloud-hosted application and services delivery within operational environments of media (e.g., just-in-time news feeds, video streaming, video gaming) content providers.
