OpenBSD is renowned for its security innovations and code quality. With its emphasis on code correctness, exploit mitigation techniques, and a rigorous development process, OpenBSD provides a rich platform and environment for developers to create robust software. This talk explores various OpenBSD programs, exploit mitigation techniques, tools, and development practices to show how you can use them to write code that is safe, robust, and resistant to exploits — even if your code is meant for platforms other than OpenBSD.
