What is a Secure Code Review? Things to Consider & Checklists

It's no secret that businesses need to do their due diligence when releasing or acquiring software. Security breaches have been a growing concern for businesses of all sizes around the world. Whether it’s from malicious hackers or a system malfunction, the impact of a security breach can be devastating.

That’s why businesses are increasingly turning to secure code reviews to give them extra assurances that their system is as secure as possible. In this article, we’ll explore what a secure code review really is, why businesses should consider them, and provide checklists to guide them through the process and relative options.

What is a Secure Code Review?

A secure code review is the process of verifying a software's security posture and assessing its ability to withstand attacks and maintain data privacy. A secure code review helps businesses reduce their risk of being exposed to security vulnerabilities and strengthens their defenses against malicious activity.

Why is a Secure Code Review Important?

When it comes to software security, businesses need to take a proactive approach. A secure code review is an essential part of any business's security strategy. By thoroughly examining the code of an application or system, a security expert can identify potential vulnerabilities that could be exploited by malicious actors. This analysis helps businesses reduce their risk of being exposed to security vulnerabilities and strengthens their defenses against malicious activity.

Secure code reviews involve more than just scanning the code for bugs and vulnerabilities. The review should also include a testing phase to ensure that the code is properly written and functions as intended. This helps to ensure that the code is robust and secure, as well as confirming that the application meets the desired security requirements.

Overall, a secure code review is an important process that every business should undertake. Not only does it help identify vulnerabilities that could be exploited, but it also provides assurance that the application is secure. A code review will also help verify compliance with modern development standards, guidelines, and best practices.

How a Secure Code Review Usually Works

A secure code review is an important step in any enterprise software development project. It is a process that involves carefully examining the source code of a program to identify any potential vulnerabilities or security flaws.

  1. A secure code review usually begins with an initial analysis of the code, during which the reviewer assesses the overall security of the program. This includes looking for any weak encryption algorithms, poor coding practices, or other potential risks.
  2. Once the initial analysis is complete, the reviewer will perform a detailed review of the code to identify potential vulnerabilities that could be exploited by hackers or malicious actors. This includes examining the program's authentication and authorization mechanisms, as well as its access control policies.
  3. Finally, the reviewer may also test the program's functionality to ensure it is robust and secure. By conducting a secure code review, companies can ensure that their software products are safe and secure for their users.

Secure Code Review Checklist

The following is a checklist of items to consider when conducting a secure code review:

  • Identify assets that need to be protected
  • Assess threats that businesses face
  • Evaluate the effectiveness of security controls
  • Identify any gaps in security controls
  • Take steps to address vulnerabilities

By following this checklist, businesses can ensure that they are taking the necessary steps to protect their software from security vulnerabilities. It is important to identify the assets that need to be protected such as data, systems, and infrastructure. Threat assessment can be more easily configured through a third-party expert, along wit identifying up-to-date risks and gaps in security controls. If you're looking to outsource the task to a third-party, there are a few things you need to have in place.

Here's a checklist of what you should have ready before getting started with a code review expert:

  • A comprehensive list of security requirements that need to be met.
  • A copy of the source code to be reviewed.
  • A list of all external libraries and third-party services used by the codebase.
  • A set of test cases to validate the code against different scenarios.
  • A copy of the vulnerability/risk assessment report for the codebase.
  • A list of any known vulnerabilities that need to be addressed.
  • A plan for how the code review will be conducted, including who will be involved and what tools will be used.

It is important to have a clear understanding of the goals of the code review. Once these goals are established, it is important to plan out the review process, including selecting the reviewers and deciding on the scope of the review. We've provided a good start to a checklist of items to look for, but it would also be good to make a note of more detailed information, such as coding style and standards, performance issues, potential bugs, etc.

Finally, make sure to document the results of the code review and follow up on any issues that were identified. All of this information will ensure that your code review is thorough, efficient, and effective.
