Overview : Secure Code Review
It involves thoroughly examining software source code to identify and fix security vulnerabilities, improving the software's quality and security. By detecting flaws early in the software development cycle, testers can prevent future breaches and attacks.
Secure code review extends beyond merely detecting errors; it evaluates deeper aspects such as architectural design, algorithms, data structures, and coding conventions. By uncovering patterns and practices, this process empowers developers to make informed decisions and minimize recurring mistakes. Its main objective is to ensure software aligns with optimal coding practices and robust security standards. Taking a proactive approach helps organizations save resources, prevent security incidents, and secure their reputation against potential risks.
Methodology
Defining the Objectives
The initial step in the secure code review process is to outline the review's objectives. Identifying key areas of concern and the types of vulnerabilities to detect will set the direction for a focused and effective review. Understanding the application’s architecture and functionality is essential, as it will guide the review process. Defining the review's scope is also crucial, as it helps prioritize which parts of the code need attention.
Review Execution:
The execution stage of a code review involves manually examining source code or using automated tools to identify security vulnerabilities, such as injection attacks and cross-site scripting. The security team focuses on detecting these flaws and understanding their root causes to develop effective mitigation strategies and prevent future issues.
Testing and Validation:
Testing and validation are essential to ensuring code security after remediation. Conduct targeted security tests, including unit tests to verify individual components and integration tests to ensure the system functions securely as a whole. Leveraging digital process automation can streamline testing and validation. Additionally, validate that all applied fixes effectively mitigate identified vulnerabilities.
Remediation:
The last stage of the secure code review process is remediation and follow-up. After identifying and reporting vulnerabilities, the development team must implement the recommended fixes and ensure they are effectively addressed.
Approach to Secure Code Review
Code Enumeration
The process starts with thorough scanning and research into the application’s architecture with the help of automated testing for known vulnerabilities. Collecting, correlating, and parsing information on the language, dependencies, and codebase is the major step towards identifying these risks.
Vulnerability Scanning
After identifying the technology stack and dependencies, we initiate automated codebase scanning. We use a mix of commercial scanning products and proprietary tools to detect security flaws. Our custom scripts, developed by numerous qualified experts, identify even the most subtle flaws that automated scanners often miss.
Manual Source Code Analysis
At this stage, we review all previous data and manually analyze the application's key areas. As we uncover potential attack vectors in these sensitive code points, we focus on identifying business impact and technical risk. Throughout every phase of our assessment, we keep the client and stakeholders informed of all critical risks we discover. Here we use manual processes to check if these vulnerabilities are present within the client’s application with the help of SANS 25 and OWASP Top 10 standards.
Reporting
Once the testing process is complete, we deliver a detailed code analysis and executive summary that includes the remediation steps. We provide a clear and concise report that includes:
1.Executive Summary
2. Strategic Strengths and Weaknesses
3.Identified Vulnerabilities and Risk Ratings
4. Affected lines of code for each security risk
5. Detailed risk remediation steps
Techniques of Secure Code Review
Automation Based
This method utilizes a variety of open-source/commercial tools for the secure code review. The majority of the time, developers utilize them while they are developing, however, security analysts may also use them. When the safe SDLC process is implemented within the business and the developers are given the ability to undertake a "self-code" review while they are working, the tool is highly helpful for code review. Additionally, the tools help examine huge codebases (millions of lines).
Manual Based
This method involves performing a full code review on the entire code, which may be a highly time-consuming and difficult task. However, throughout this procedure, logical errors such as business logic issues could be found that are impossible to find with automated techniques.

FAQs
When to Perform a Secure Code Review?
The optimal time to do a secure code review is near the end of the source code development process, after the majority or all functionality has been developed. A secure code review costs money and takes time, which is why it is postponed until late in the development phase. Cost-reduction is aided by carrying it out just once near the end of the development phase
What aspect of code review is most crucial?
The primary goal of a code review should be to provide helpful criticism that will improve the code's readability, maintainability, and bug-free nature.
What are the factors to bear in mind during secure coding?
- • Security by Design
- • Access Control
- • System Configuration
- • Password Management.
- • Input Validation and Output Encoding.
How does secure coding work?
- By adhering to code security best practices, secure coding safeguards and shields published code from known, unknown, and unforeseen vulnerabilities like security exploits, the loss of cloud secrets, embedded credentials, shared keys, confidential business data, and personally identifiable information (PII)
