What is Code Audit

Even a single mistake or flaw that surfaced after the product was released might have disastrous results. This is why businesses make significant investments in testing and QA. Auditing software code is the solution if you want to hasten the launching of your product and lessen security flaws and risks.

What is a software code audit?

A source code audit is a process of examining the source code for a software project in development to find flaws, mistakes, loopholes, and breaches.

An audit seeks to fix mistakes before the product is released since it is a preventive programming technique.

An effective code audit service can:

  • uncover outdated practices and tools;
  • assess security threats;
  • identify flawed methodologies.

Software testing can help to avoid subsequent, more severe issues, as experts in company believe. It enables businesses to improve the quality, safety, and manageability of a software product.

Reasons to get a code audit

If you have any of the following, conducting a code audit is advised:

  • the use of most likely outdated practices or technologies;
  • performance concerns;
  • something is affecting the functionality of your product, but you are unsure of what;
  • no code audit in more than six months.

The development of any software product should include a code audit in it. It makes sure the code is comprehensible, and the product is fully prepared for release.

Main types of code audit


In most cases, it is not essential to examine the entire product as it takes excessive time and effort. Frequently, inspecting the product’s individual components is all that is actually needed to ensure good performance and safety of the product.


A manual audit reveals the initial and partial representations of the program code. It also aids in determining if the code was built in accordance with industry guidelines.


An audit of the front-end code can assist in identifying any problems with the sections of the code that are in charge of creating a positive user experience.

The front-end specialists concentrate their attention on factors like overall performance and design responsiveness throughout this kind of code assessment.


A back-end audit determines the overall code complexity. Examining its stability and management of any possible security threats is always helpful. The auditors focus very closely on details like obsolete equipment, outdated software, and surplus code.



An audit of the infrastructure concentrates on how the servers operate, and makes sure that the configuration is safe and that the servers are updated, ensuring that there are no possible security threats.

The infrastructure audit overall enhances website performance. This makes certain that those servers can operate efficiently.

An audit of the infrastructure code aids in server optimization and cloud storage security. It determines whether a product utilizes more servers or cloud storage than is actually necessary. After that, an audit will identify opportunities to cut back on some of these.


Finding any security holes or improper database access is made easier with the use of the security code audit. Additionally, it aids in the detection of security loopholes that might allow confidential data to leak.

A security code audit often assists in identifying flaws in the code, preventing additional expenses for issue fixes, and creating a checklist of potential security risks to know more about.

Companies mostly utilize static and dynamic security code audit approaches in order to prevent expensive vulnerabilities.

Benefits of Code Audit

Because auditors analyze all aspects of the software’s architecture, including coding and design standards, understanding how the code works inside out will help them address problems quicker with better efficiency. Generally, during an audit process essential aspects such as project-wide structure analysis, comparisons with industry standards, review for accuracy, and suitability for purpose will be covered. By doing so developers can spot any potential issues early on such as unsanitary programming practices or unnecessary complexity such as complicated state machines that may cause conflict between components at various points in time.

By completing an audit process regularly, developers can be sure they are keeping up with industry trends while ensuring their behaviors remain consistent across several projects or releases.

Code audits can also detect any functional programming errors or hidden bugs that could otherwise go unnoticed until later production stages when they may cause further problems downstream. Additionally, regular audits will lead to a better user experience overall by addressing coding-related issues such as low performance or resource utilization which would otherwise give bad customer reviews whenever found through post-deployment testing.

Ultimately, this approach can provide stakeholders greater assurance that their resources are producing valuable results for their business operations unseen by users thus leading to improved customer satisfaction rates over time too.

How to Perform a Code Audit


There are a number of tools available for performing a code audit depending on the environment where your application will be deployed (e.g., web applications require different tools). Here are some examples:

  • Static Analyzers: A static analyzer performs an automated review of source files without actually executing them. These programs look for variables that aren’t declared, unused variables, instances where a derived class does not override a method in its superclass, etc.
  • Dynamic Analyzers: This type of analysis relies heavily on testing techniques wherein scripts or applications can be executed against given sets of data so that possible bugs can be identified before runtime errors occur. These tests may look at internal details such as memory accesses or loop entries/exits to find hidden issues relating to memory leaks or thread synchronization faults.
  • Software Metrics Analysis: measures software characteristics such as complexity levels based on how many lines of code there are in each module etc., with reports providing developers with unique insights into related projects allowing them to quickly assess their progress towards meeting milestones against established development plans.


At the end of a code audit, the auditor should have produced a report with an assessment of the codebase. This includes identifying any existing bugs or issues that could lead to building failure, performance alerts, and technical debt blocking continuous deployment. The report should also contain proposed improvements and recommendations to make the application more robust, reliable, and secure.
