Secure code review is the process of manually examining source code to identify and fix security vulnerabilities. The goal of secure code review is to ensure that the code being developed is secure and does not contain any known vulnerabilities. This process is an essential part of software development, and it shall be  performed throughout the development lifecycle, from design to deployment.

The secure code review process typically involves a team of security experts who manually review the source code, looking for potential vulnerabilities such as SQL injection, buffer overflow, and cross-site scripting (XSS). They also check for compliance with security standards and best practices.

The deliverables of a secure code review typically include a report that summarizes the findings of the review, including a list of identified vulnerabilities, their severity, and recommendations for remediation. The report also includes a description of the review process, the scope of the review and the tools used.

There are several different methodologies that can be used for secure code review:

1. Manual code review: This is the most common methodology and involves a team of security experts manually reviewing the source code, looking for potential vulnerabilities and compliance issues.
2. Automated code review: This methodology uses automated tools to scan the source code for potential vulnerabilities and compliance issues. The results of the scan are then reviewed by a team of security experts.
3. Hybrid code review: This methodology combines both manual and automated code review, using automated tools to scan the source code for potential vulnerabilities and compliance issues, and then having a team of security experts manually review the results.
4. Peer code review: This methodology involves having other developers review the source code for potential vulnerabilities and compliance issues.
5. Penetration testing: This methodology simulates an attack on the software to identify vulnerabilities and assess the effectiveness of the security controls in place.
6. Threat modeling: This methodology uses a structured approach to identify, communicate, and understand potential threats and vulnerabilities in the software.

The choice of methodology will depend on the specific organization and the scope of the code review. Some organizations may use a combination of different methodologies to provide a comprehensive assessment of the security of the software.
