Guidelines For Performing A Safe Code Audit

Static application security testing (SAST) tools are automated code scanners that may find several typical coding flaws that result in vulnerabilities. By enforcing naming conventions, formatting, and comments, code analysis tools make sure it complies with the organization’s coding standards and flag any obsolete or vulnerable parts. Manual code review is simplified by a well-commented, uniform coding style. Know more about secure code review.

There are several commercial and open-source SAST tools that may be launched directly from the IDE without leaving the programming environment. Because of this, developers may perform baseline tests anywhere they like to ensure their code is free of common flaws like those listed in the OWASP Top Ten and the Common Weakness Exploitation Pattern.

What are SAST tools?

Complex business logic and custom applications are difficult to test using SAST tools because of their reliance on static data. Therefore, manual code inspections aid developers in concentrating on project-specific security needs and implementing security-critical components. The software design phase’s threat modelling report dictates the need for manual code execution. Security policies, privacy, and regulatory requirements may all be upheld thanks to the information gleaned from these studies on possible threats, vulnerabilities, and mitigation strategies.

Before incorporating changes into the master branch of a project, developers should do a thorough security audit of all code. Remember that pull requests with fewer commits are less work to examine. Before submitting a pull request, developers should run the SAST tool and unit tests and fix any problems or warnings that are found. Code complexity measurements are an ideal output of the SAST tool; too complicated code is hard for others to understand and makes discovering possible issues more challenging.

After that, you may start going through the code’s logic to find security holes in the control and logic flows that the original developer may have overlooked.

If the code checks out, it can be merged into the main project, but if there are problems, the pull request should be denied. Developers may increase their expertise in security and learn how to make better future pull requests by carefully reading and responding to reviews. Increasing training and policy knowledge can boost security and team efficacy if the same problems keep cropping up. These evaluations produce metrics that enhance code quality and productivity in the future, such as the percentage of pull requests denied, the severity of mistakes identified, and the average response time.

There will always be flaws in software, but the consequences of a security flaw can have grave consequences. Code security must be reviewed on a regular basis. As a result, applications are safer, costs are reduced, and developers can track their progress in designing secure code and reducing frequent mistakes.
