It uses different methods, such as following data from it source (input) to its sink (output) to identify potential weaknesses. It also uses simple search methods in an attempt to identify hard-coded values, like passwords in the code. Automated tools struggle at finding business logic or authentication/authorization flaws. Code Review is a much larger project where both … [Read more...] about What is the difference between source code review and static analysis?
