Explore a comprehensive conference talk that delves into wasmCloud's multi-tier security model and its approach to securing distributed WebAssembly applications. Learn how to address critical security challenges in an era where 96% of codebases contain open source components and face a 54% increase in high-risk vulnerabilities. Discover the platform's deny-by-default security model that requires developers to explicitly declare application capabilities while enabling platform engineers to implement fine-grained control through pluggable services. Through practical demonstrations and real-world examples, gain essential knowledge about configuring and extending security measures using pluggable services to enhance the protection of cloud native applications built with WebAssembly.
