Source Code Review
-
Source code review, also known as Security Code Review is the process of auditing the source code for an application to verify that the proper security controls are present, that they work as intended, and that they have been invoked in all the right places. Code review is a way of ensuring that the application has been developed to be “self-defending” in its given environment.
