Rockstar🎓
Top SchoolStephen Smalley is a senior technical leader with 26 years of experience in system security architecture, currently heading Trust Mechanisms research at the NSA's Laboratory for Advanced Cybersecurity Research. He is a founding developer and long-time lead of the SELinux project and the SE for Android effort, partnering with Google, Samsung, Red Hat and others to harden Linux and Android deployments. His work spans runtime integrity, eBPF, confidential computing and hardware-enforced memory safety, and he has led creation of secure Linux baselines for high-assurance environments. A pragmatic engineer as well as researcher, he combines deep upstream open-source contributions (notably to SELinux and Android framework security) with hands-on policy and tooling development that improves deployability and debuggability in production systems.
