Secure Code Review is an approach used to find an insecure piece of code that may lead to a potential vulnerability.
The software development phase needs to be monitored in a way so that the code may not create insecurities in the application.
The Software Development Life Cycle (SDLC) is used to monitor and check for vulnerabilities in the software, but when the application is ready to be launched in the market and code has vulnerability it may lead to a greater loss.
Therefore, a secure code review is an important factor that checks for the quality of code to stop any vulnerability.
The secure code review comes under the development phase where developers look for bugs in the code or security analysts perform the task of reviewing the code.
The analysts use automated tools that are integrated into the IDEs to find vulnerabilities or bugs in the code. Security experts play an essential role as they highlight and explain security vulnerability to the developers and they fix it according to the standards.
Developers tend to deliver the project within the given deadline and as a result, they miss security measures, which is then recovered by the security experts.
The research and different studies illustrate that almost 75% of the security attacks take place due to the presence of a flaw in the code.
When security code review is ignored it results in leading security breaches as attackers love to have flaws and vulnerability in the application code.
Effective software is usually the result of pro-active development and using secure code review once the development is complete.
Input in Secure Code Review
At a low level, for conducting security code review the availability of code is must along with the following things that could help in effective security code review:
Step 1: In the first step of security code review identification objectives are done where constraints and goals are defined.
Step 2: The preliminary scan is a crucial part as it helps in identifying security issues to review the code effectively.
Step 3: In this type, the practical approach is used to review the code thoroughly according to the goal that is set. The deep analysis and scanning in the previous step make a positive impact on this step to review the code for security issues.
Step 4: The final step about security issues is to relate a unique architecture to the software, in this step the security experts and developers design and implement a specific security posture to make the code secure.
In the graph, it can be seen that step 2, 3, 4 are repetitive that needs to iterate until and unless secure code is obtained.
The activity that takes place in the secure code review defines vulnerabilities in the code that the experts get as an output. The result is then prioritized to use strategic approaches to eradicate the vulnerability or flaw from the code.
