Why Do You Need a Software Code Audit and How Can You Make It Work?

There are always loopholes and last-minute errors, even if you run various unit and acceptance tests during your software development. As a result, a code audit serves as both a “regular check-up” and a “final look” to ensure that the application and its components are free of security flaws and other potential problems.

1. What is a Code Audit?

A software code audit is a comprehensive source code analysis of a software solution or product. It is regarded as one of the most critical stages of the security process. It validates the code maturity and maintainability, ensuring that the product is ready for a seamless handover.

2. What is the Importance of Software Code Audit?

Usually, a software code audit has the following primary goals – while additional ones could be incorporated per request, such as conformity with the adopted code style:

  •   Get acquainted with the present project structure and functionality
  •   Discover existing and potential bugs
  •   Discover security breaches and vulnerabilities
  •   Validate the current performance and scalability
  •   Assess the code maintainability level and associated risks and costs
  •   Verify conformance with relevant software development standards, guidelines, and best practices

In addition to these goals, and from a business perspective, reviewing code allows a company to save money and avoid losing potential customers because of launching or offering a substandard product.

3. What is the software code audit process?

Code Audit is testing the Source Code. The code review process aims to assess any new code for errors, bugs, and quality standards set by the organisation.

A code review is an integral part of the defensive programming model that attempts to reduce errors before software release. Software reviews and audits involve a comprehensive website code analysis and include effective troubleshooting versions of development processes in the earliest stages.

The software engineer’s core business profile is the development, implementation, maintenance of software products and design, documentation, versioning, restructuring, and code review.

Code review is beneficial for the following reasons:

  • Ensuring that you have no bugs in the code.
  • Determining the security risk and minimising the chances of having issues.
  • It helps to confirm that the new code adheres to guidelines.
  • Enables you to increase the efficiency of the new code.

Code review helps improve the software code’s quality and decreases the program code’s bugs and errors, leading to enhanced customer satisfaction and retention. It is also the best way to share knowledge across the team and mentor less-experienced developers.

4. How do you conduct a code audit?

In a code review process, developers review each other’s source code. There are two roles present in a peer code review: the creator and the reviewer.

The creator is the person responsible for developing the reviewed code. The reviewer is the person responsible for examining that code.

There are four commonly used approaches to perform effective code reviews:

4.1 Over–the–shoulder

The over-the-shoulder is an informal and the most straightforward code review approach. In this technique, an experienced team member goes through the new code and gives suggestions.

4.2 Group discussion

Someone who has an idea suggests a way of solving an issue. This includes a sketch in the base or an approach to architecture. The team then provides input as to what the system overview should be. The best-case scenario and the best solution are usually the initial ideas.

4.3 Pair Programming

Pair programming is a time-consuming continuous code reviewing process. Two developers work together – one actively codes, and the other provides real-time feedback. This approach is very collaborative.

4.4 Tool-assisted code review

A tool-assisted code review process involves using a specialised tool to facilitate the process of code review. Tools help you assess the efficacy of the code review process with metrics, organise and display the updated files in a change, and facilitate communication between reviewers and developers.

All the techniques above are instrumental and will result in better code. No matter which approaches you to choose or combine, code review is a great way to find bugs, mentor new employees, and share relevant information.

5. What’s the Most Effective Way to Perform a Code Review?

Reviews can be done via both manual and automated methods. At TechDel, whenever we have to make a code audit, we utilise a balanced software audit strategy that employs automatic analysis tools to perform searches for common issues and vulnerabilities and input from our senior software engineers to detect more complex subtle problems.

Manual analysis should be performed per major solution component and the whole solution, starting with high-risk checklist issues and working down to low-risk ones.

6. Quick Tips for Conducting an Effective Code Audit

Following are some of the tips which help in conducting an effective and successful Code Audit:

  •   Define the scope and create a code review checklist to ensure consistency across all team members and guarantee critical issues are addressed and solved.
  •   Ensure you utilise both automated and manual code review to enable the most effective code analysis.
  •   Avoid playing the “blame game” with developers every time you find a mistake. Instead, build a solid and positive security culture and use this opportunity for your team to grow and learn.
  •   Consider bringing a third-party code auditor; a new set of eyes will reveal more things that your current development team often considers common knowledge “no issues”.
  •   Perform regular code audits to save time. Leaving it to the last minute means that the app will be reviewed all at once, thus taking more time and delaying the deployment process, potentially revealing many logical issues and security vulnerabilities.

7. Conclusion

The code review is used to determine how much time and money the subsequent phase will require and why it will take so long. After a code audit, we can build a plan for your firm’s future, beginning with a safe and reliable codebase.

A code review produces a report that identifies your vulnerabilities and predicts the time it will take to bring your code up to date and offer clients the best potential remedies.

Code auditing is complex, but with the help of a committed team of professionals, you can avoid significant bugs, save money, and successfully resolve security and maintenance issues.

Ultimately, constant code audit should be a part of any mature software development process, whether Agile or Waterfall-based software development. You can control the product’s quality, maintainability, and security by doing it regularly. Plus, if the necessity arises, you’ll have the option of a simple project turnover.
