Code Review
There are number of software code review tools available for developers and testers to check, analyze and fix the possible risks in desktop and web applications. These tools have been designed to review compiled version of an application source code to find security risks and repair them. A source code review tool must select a security flaw on the basis of such consistency and confidence that it should be indeed a flaw, not tool’s mistake. In practical cases, finding security flaws is beyond the state of art of many code review tools. However, they work as support and aiding the software developers, testers to find security vulnerabilities and alert them just in time.

Some source code review tools are moving into the internal development environment of various software applications. It is quite beneficiary to implement such tools to detect bugs and security risks during software development phase and make quick feedback possible. Finding security risks and vulnerabilities during initial software stages is much easy to overcome the issues instead of finding and repairing them in later stages of the SDLC. Such tools scale well and can be used for lots of the desktop, web and mobile interface applications. They can easily find SQL injection flaws and buffer overflows.

Pre-commit and post –commit are two major types of the code review and most of the code review applications provide both review types. In pre-commit review type, a code is reviewed before going to codebase and a file ”diff file” to reviewers for changes, comments and general approval. In cast of post-commit code review, code is reviewed after uploaded into the server codebase. Pre-commit is advantageous because a mistake is found in its early stage before code is upload into to codebase. In post-commit review method, reviews are made after code has been uploaded and fixations are performed if required. In web UI, review teams support pre-commit because of its access and mistakes being caught before code moved to SVN.

Code Review Process

Code review process is where software architects, developers and testers meet and discuss about the specified software application security concerns. A key reason of code review process is to discuss and exchange the ideas about how source code will be interpreted. During source code review process, the key focus of team should be on issues such as object-oriented programming, data structure diagrams and algorithm used. For code review process to be efficient, it is important that teams should sit in a creative and fun environment. In this way, code review groups can drop certain tools and techniques to strength the development process.

Here is a comparison of top free and paid source code review tools,
