​Software is not only eating the world, but also defining the new world. With the increasing examples such as software-defined compute/storage (aka, cloud), software-defined networking, software-defined radio/5G, and software-defined vehicle, we are now living in a world of software-defined everything (SDx). Infosys estimated that the global SDx market will reach USD 160 billion by 2024 and grow at a compound annual growth rate of 25%. The security of SDx is becoming more interesting and important. On one hand, SDx presents new attack surfaces and security challenges. On the other hand, SDx also provides new opportunities to rethink the design of security. In this talk, we will revisit the security at both sides and demonstrate with our recent research results. In particular, we show that we can well leverage software-defined principles to enhance zero-trust security and design new programmable security frameworks, thus also making this software-defined world more secure.​
