a graphic and concept called the "lethal trifecta” by Simon Willison, co-creator of the Django Web framework. The lethal trifecta holds that if your system has access to private data, exposure to untrusted content, and a way to communicate externally, then it’s vulnerable to private data being stolen.This image shows three boxes of different colors: access to data, ability to externally communicate, and exposure to untrusted content.
