In an increasingly digital world, software security cannot be an afterthought—it must be embedded in the very languages and frameworks we use to build systems. This lecture series explores how programming languages, especially functional ones, can be used to design software that is secure by construction.

Drawing from real-world applications and cutting-edge research, the lectures will cover topics such as protecting sensitive data with Differential Privacy, enforcing security policies through information-flow control, and ensuring data confidentiality in cloud-based systems using secure programming models. The series will balance theory and practice, showing how abstract principles can lead to concrete tools that help developers build more secure systems from the ground up. Designed for a wide audience—from students to professionals interested in secure computing—the series will demystify complex security techniques and demonstrate how programming language design plays a critical role in safeguarding our digital infrastructure.
