This, combined with the documentation produced as part of the threat modeling process, can give the reviewer a greater understanding of the system. The inclusion of threat modeling in the SDLC can help to ensure that applications are being developed with security built-in from the very beginning. Threat modeling is not an approach to reviewing code but it does complement the security code review process. It is a structured approach that enables you to identify, quantify, and address the security risks associated with an application. Threat modeling is an approach for analyzing the security of an application. The most important is applying the proper Thread modeling. What is the most important thing in a code review Tools are good at assessing large amounts of code and pointing out possible issues but a person needs to verify every single result to determine if it is a real issue, if it is actually exploitable, and calculate the risk to the enterprise. Tools do not understand context, which is the keystone of security code review. Important note: Tools can be used to perform this task but they always need human verification. Tool-assisted code review – Authors and reviewers use specialized tools designed for peer code review.Pair Programming – Two authors develop code together at the same workstation, such is common in Extreme Programming.Email pass-around – Source code management system emails code to reviewers automatically after checkin is made.Over-the-shoulder – One developer looks over the author's shoulder as the latter walks through the code.Lightweight reviews are often conducted as part of the normal development process: Formal inspections are extremely thorough and have been proven effective at finding defects in the code under review. Lightweight code review typically requires less overhead than formal code inspections, though it can be equally effective when done properly. Formal code reviews are the traditional method of review, in which software developers attend a series of meetings and review code line by line, usually using printed copies of the material. Formal code review, such as a Fagan inspection, involves a careful and detailed process with multiple participants and multiple phases. It is often done by independent contractors or an internal security team, hiring a third independent party to perform the code review adds value because it gives to the company the chance to examine its code by a person that has been engaged in the last stage of the development process and has no "emotional attachements to the code" therefor has a unique perspective on the subject.Ĭode review practices fall into three main categories: 1) pair programming, 2) formal code review and 3) lightweight code review. Reviews are done in various forms such as pair programming, informal walkthroughs, and formal inspections. ![]() A security code review is a systematic examination of a Web Application source code that is intended to find and fix security mistakes overlooked in the initial development phase, improving both the overall security of the software. But first lets define what is a security source code review.
