A secure code review is a specialized procedure that entails manually and/or automatically examining the source code of an application to find weaknesses in the design, discover unsafe coding techniques, find backdoors, injection flaws, cross-site scripting problems, weak cryptography, etc. The goal of secure code review is to improve the code’s security and uncover any flaws before they may cause any harm. Insecure code that could potentially result in a vulnerability at a later stage of the software development process and ultimately result in an insecure application is found through a procedure called secure code review.
The secure coding review process is divided into two different techniques –
This method employs a variety of open source/commercial tools for the secure code review. The majority of the time, developers utilize them while they are developing, however security analysts may also use them. When the safe SDLC process is implemented within the business and the developers are given the ability to undertake a “self-code” review while they are working, the tool is highly helpful for code review. Additionally, the tools are helpful for examining huge codebases (millions of lines).
This method involves performing a full code review on the entire code, which may be a highly time-consuming and difficult task. But throughout this procedure, logical errors such as business logic issues could be found that are impossible to find with automated techniques.
Carrying out a threat analysis to comprehend the architecture of the application. These threats need to be prioritized among the vulnerabilities during the code review. The organization’s essential applications must be identified, and a threat assessment must be done for that group of applications.
Code review is carried out during automation using a variety of paid/free technologies. Automated technologies are frequently used to analyze huge code bases with millions of lines of code, speeding up the code review process. They are capable of locating all the unsafe code packets in the database, which the developer or any security expert can then examine.
In order to verify access control, encryption, data protection, logging, and back-end system connections and usage, manual code review is the only method available. A manual inspection is crucial for tracking an application’s attack surface and figuring out how data moves through an application from sources to sinks. Although going line by line through the code is expensive, it improves code readability and also aids in reducing false positives.
Following the completion of the automated and manual reviews, we thoroughly verify any risks that may have been identified as well as any potential remedies for any known codebase vulnerabilities.
After completing all of the aforementioned stages, we compile all of our findings into a report that is easy to read. Every bug is tested in the code along with the patching solutions. Secure coding and secure code reviews should be used in conjunction to harden the development team’s code. The client’s development team and Kratikal’s security team discuss the problems and suggestions, and the development team fixes them as a result.
The reporting step’s objectives are to present, rank, and prioritize findings as well as to give project stakeholders a concise, actionable report with accompanying data. At Kratikal, we consider this to be the most crucial stage, so we take great care to ensure that we have adequately communicated the significance of our findings and service.
