OWASP’s Top 10 Risk List is an important tool for security engineers and compliance analysts. It describes the 10 worst security problems that are found in web and mobile applications today. But, on its own, it’s not much help to developers, so OWASP has come up with a list of 10 things that you can do as a developer to make sure that your code is safe and secure.
