Explore the concept of Software-Defined Networking (SDN) and its implications for security in this 49-minute conference talk from HouSecCon 6 (2015). Delve into the evolution of SDN architectures, modern IT requirements, and the driving forces behind this technology. Learn about DMZ/inline service chaining, public/private cloud interconnection, and data center NFV/service insertion. Discover how event-triggered monitoring and REST API-driven programmatic policy creation contribute to network security. Examine the concept of micro-segmentation and its role in enhancing network protection. Gain insights from practical examples and lab demonstrations to understand the potential of SDN in redefining network security paradigms.
