There is no one-size fits all security, and no one tool will make you secure. Security threats can come from a variety of different actors, and attacks can be technical, social, physical, or legal. Threat modeling is an integrated approach to security based on an assessment of your specific situation. You will learn the basic questions you need to answer to determine your security needs, how security threats vary depending on what you’re working on and where you’re working on it, and how to design a security plan including determining which tools and services you should use.
