Source Code Review: A Brief Overview

Source code review is a manual or automated technique for inspecting an application’s source code. This testing aims to detect any current security flaws or vulnerabilities. The source code review include security, performance, functional level issues, etc.

Automated code review is when a program automatically evaluates an application’s source code, looking for errors based on a preset set of rules. Automated review can uncover flaws in source code faster than manual inspection.

Manual source code review entails a person inspecting source code line by line to identify flaws. Manual code review clarifies the context for coding decisions. Automated tools are speedier but must consider the developer’s goals or overall business logic. Manual review is more deliberate and addresses particular concerns.

Why is Source Code Review Important for Organizations?

Why is a source code audit necessary? A peer code review provides several advantages to a software development team, including:

  • Code review sessions assist in uncovering evident logical problems in source code, ensuring that it is excellent code.
  • A code review exercise can determine if the code meets the requirements and design specifications.
  • Code reviewers can determine if the code meets the organizational standards and norms.
  • Structured code review sessions can reveal if the software is sufficiently maintainable.
  • A code review can assist a software development team to determine if it has produced enough test cases.

Benefits of Performing Source Code Review

Code review is a peer assessment of code before formal testing begins. It is beneficial in various ways, including identifying issues early on. Source Code Review improves communication and teamwork to guarantee high-quality code is provided. Here are the top benefits of reviewing your source code:

1. Ensures Consistency in Implementation

Large projects, unsurprisingly, involve numerous developers. If developers continue to use their coding styles during development, it stifles collaboration and slows overall progress. The code review process requires developers to adhere to specific coding principles throughout the sprint development period. 

Code review is important in the long run since team members shift during projects. Furthermore, a consistent coding structure will allow future developers to spend more time developing new features than evaluating current code.

2. Optimizing Code for Higher Performance

Developers need to gain the necessary knowledge; therefore, they are ignorant of certain code optimization strategies that might help them produce clean code. The source code review process allows them to receive appropriate input from expert testers, which helps them refine their coding skill sets. 

It also aids in detecting major mistakes or faults, which can lead to serious issues. Because programming is so boring, even the most experienced coders are prone to overlooking errors. Code review helps to eradicate these errors before moving on to the next phases by inviting a new set of eyes to evaluate each code unit.

3. Making the Code More Maintainable

Code review improves the code’s maintainability. It guarantees numerous individuals know the code’s logic and functionality, making it easier to maintain if the original author is absent.

Code review can assist with such instances by checking the generated and desired features. This guarantees that any misconception about the scope or requirements is corrected immediately. This also ensures that teams take advantage of important features.

4. Risk Mitigation

Open source code review is integral to software development projects’ risk reduction strategies. They contribute to the early detection of security vulnerabilities and possible threats in the development lifecycle. You can proactively defend your program from possible risks by resolving these vulnerabilities proactively.

Furthermore, code evaluations verify adherence to industry norms and standards. By thoroughly examining the codebase, you may ensure that your program fulfills the relevant standards, such as data protection, accessibility, or industry-specific rules. Surprisingly, this keeps you on the right side of the law and shields you from possible legal and reputational ramifications.

How is the Source Code Review Security Assessment Done?

Businesses should verify that remedies are properly implemented after detecting security problems in the code. Here’s the detailed breakdown of the source code review security assessment procedure:

1. Information Gathering

Gathering information and analysis are the most important aspects of a good code review process. The phase differs between applications due to a variety of reasons. It may be the programming language, the intricacy, or the amount of lines in the code. Another necessity of the phase is to determine the criticality of the application. By doing so, source code security review teams get information about what to emphasize while evaluating.

2. Auto Tool Scanning

An automated scanning procedure inspects each byte of coding using automated tools to produce the desired result. Later, it is compared to the desired outcome to detect any deviations. A static code review team uses automated scanning technologies for specific tasks. Automated scanning technologies must integrate pipelines, tailor to specific demands, and keep false positives to a minimum.

Secure code review tools are quite useful for security experts. Secure code reviews may be carried out using a variety of tools, including:

  • Dynamic Analysis Tools (DASTs): These evaluate an application’s behavior while executing. 
  • Penetration testing: These tools mimic application assaults to uncover flaws that attackers may exploit.
  • SAST code review Tools: These tools evaluate an application’s source code without executing it.
  • Code Review Checklists: These are lists of probable security flaws that developers may use as a reference while examining their code. They can assist in guaranteeing that all possible vulnerabilities are addressed during the evaluation process.
  • Manual Source Code Analysis: While tools are useful, they cannot replace the skill of a human reviewer. Manual code reviews require a skilled security specialist to review the code line by line to find potential vulnerabilities.

3. Manual Pentesting

Manual secure code review testing drills logical problems, poor system settings, and validation attempts into code using line-by-line examination. It also checks for other known flaws in your codebase that are particular to the platform. Human context is important since such testing is performed on high-risk and sensitive applications

4. Reporting

A prioritized action plan for the test results links to the reporting phase. Entities must adhere to the best practices outlined in the source code review report and consolidate any potential deviations in a prioritized strategy. A robust reporting procedure contains an ideal road map for managing the risks connected with the codebase. The review team provides support to developers and the security team as needed.
