The lazy programmer’s guide to secure computing
This presentation starts with a simple block of code written by the Lazy Programmer, to observe how laziness made the code more compact and simpler. We then define the Principle of Least Authority (POLA), and explain why it is a best practice for secure programming. We show how laziness in that first example enabled enforcement of POLA. We then put the Lazy Programmer through a series of increasingly more difficult tasks as management attempts to make the Lazy Programmer work hard.
