Why code security review is needed?

Programmers often follow incorrect programming practices which leads to security loopholes. To mitigate the risks, it is important to perform code review to capture security loopholes, before the code it deployed on to live production systems. Code review and code analysis enables your developers to review, find, and eliminate vulnerabilities before an application goes live and helps software purchasers identify flaws in applications before they buy.

Many organizations use tools but it had been observed that this method has its own obvious limitations. Because of this, the inaccurate results can waste your developers' time in hunting down false positives, thus slowing development timelines to the point where competitiveness suffers. But with the security of your enterprise on the line, you need some way to review code quickly and cost-efficiently. That's where Valency Networks can help.

PROCESS

The process of a code security review service typically involves several steps to assess the security of an application's codebase comprehensively. The process is as follows:

Requirement Gathering:The service provider collaborates with clients to understand their needs and requirements. This includes gathering information about the application, its purpose, technology stack, existing security controls, and any specific compliance standards or regulations that must be considered.

Code Access and Preparation:The client provides access to the application's source code, which is securely shared with the service provider. The code is prepared for review by ensuring it is appropriately documented, organized, and ready for analysis.

Code Analysis:The service provider conducts a detailed analysis of the application's source code. This analysis can involve manual and automated techniques to identify security vulnerabilities, coding errors, and potential weaknesses. Static code analysis tools may assist in identifying common security issues and adherence to coding standards.

Vulnerability Identification:The code review process identifies various security vulnerabilities, such as injection attacks, authentication and authorization flaws, sensitive data exposure, cryptographic weaknesses, and more. The goal is to detect potential vulnerabilities that attackers could exploit.

Security Compliance Assessment:The code review also evaluates the application's compliance with relevant security standards, frameworks, and industry regulations. This ensures the code adheres to established security guidelines and best practices, reducing the risk of non-compliance and potential legal or regulatory issues.

Reporting and Documentation:The service provider prepares a comprehensive report detailing the code review findings. This report includes identified vulnerabilities, their severity, and recommendations for remediation. It may include an executive summary, technical details, and supporting evidence to help the client understand the identified issues.

Remediation Guidance:Along with the report, the service provider provides remediation guidance to assist the development team in addressing the identified vulnerabilities. This guidance may include specific code modifications, secure coding practices, architectural changes, or recommendations for implementing additional security controls.

Follow-up and Collaboration:The service provider discusses collaboratively with the development team to address any questions or concerns about the code review findings. They may assist in prioritizing and implementing the recommended fixes, offering ongoing support and guidance throughout the remediation process.

Reassessment and Validation:After the remediation efforts, the service provider may perform a follow-up review to validate the effectiveness of the applied fixes. This helps ensure that the identified vulnerabilities have been successfully addressed and that the security of the codebase has been improved.

Continuous Improvement:The code review process is often integrated into the organization's development lifecycle as an ongoing practice. Lessons learned from each review are incorporated into future development efforts, promoting a culture of continuous improvement and proactive security measures.
