Description
What is it?
Static Code Review, or Static Code Analysis, is a software testing method where source code is examined manually or with automated tools without actually executing the program. It's like meticulously proofreading a document before publishing it, looking for errors, inconsistencies, and potential problems. In the context of security, it's about finding vulnerabilities, coding errors, or design flaws that could lead to security breaches or exploitable weaknesses.
Technical Data
| How to do it? | |
|---|---|
| Preparation | |
| Gather Code & Documentation | Collect the source code, relevant design documents, and any coding standards or security guidelines the project adheres to. |
| Define Scope | Decide which parts of the code will be reviewed, considering the project's size, criticality, and available resources. |
| Select Reviewers | Choose individuals with appropriate expertise in the programming language, security, and the system's architecture. |
| Manual Review | |
| Individual Analysis | Reviewers independently examine the code, looking for: |
| Security Vulnerabilities | Issues like SQL injection, XSS, buffer overflows, etc. |
| Coding Errors | Logic errors, memory leaks, resource mismanagement, etc. |
| Design Flaws | Architectural weaknesses, poor error handling, insecure data handling, etc. |
| Standard Violations | Deviations from coding standards or security guidelines. |
| Collaborative Review | Reviewers discuss their findings, share insights, and clarify any ambiguities or complex code sections. |
| Automated Tool Support | |
| Static Analysis Tools | Employ tools to automate parts of the review process, such as: |
| Linters | Identify syntax errors, style inconsistencies, and potential bugs. |
| SAST (Static Application Security Testing) Tools | Scan code for known vulnerability patterns and security weaknesses. |
| Data Flow Analysis Tools | Track how data flows through the code to uncover potential security risks. |
| Document Findings | |
| Record Identified Issues | Create a detailed report of all findings, including their location, severity, potential impact, and recommended remediation steps. |
| Prioritize | Assign priorities to findings based on their criticality and likelihood of exploitation. |
| Remediate & Verify | |
| Address Identified Issues | Work with developers to fix the identified problems. |
| Re-review | Conduct follow-up reviews to ensure issues are addressed correctly and no new problems are introduced. |
| Software Used | |
| Manual Code Review | |
| Version Control Systems (Git, SVN, etc.) | Facilitate code sharing and review tracking. |
| Code Editors/IDEs | Provide features for navigating and commenting on code. |
| Collaboration Tools | Support communication and documentation among reviewers. |
| Automated Tools | |
| SAST Tools | SonarQube, Coverity, Fortify, Checkmarx, Veracode, etc. |
| Linters | ESLint, Pylint, RuboCop, etc. |
| Other Specialized Tools | Depending on the programming language and project needs. |
| Standards for Testing | |
| OWASP Code Review Guide | Provides comprehensive guidance on conducting secure code reviews. |
| CERT Secure Coding Standards | Language-specific secure coding guidelines (C, C++, Java, etc.). |
| MISRA C/C++ | Coding standard for safety-critical systems. |
| CWE (Common Weakness Enumeration) | A dictionary of software weaknesses and vulnerabilities. |
| Industry-Specific Standards | PCI DSS, HIPAA, etc., often have code review requirements. |
| Key Points | |
| Essential for Security | Static code review is vital for uncovering vulnerabilities and design flaws that automated tools might miss. |
| Early Detection | Identifies issues early in development, reducing costs and delays associated with fixing them later. |
| Improves Code Quality | Helps enforce coding standards, improve maintainability, and reduce technical debt. |
| Requires Expertise | Effective reviews require skilled reviewers with knowledge of security, the programming language, and the system's architecture. |
| Complementary | Static analysis is most effective when combined with other testing techniques like dynamic analysis and penetration testing. |
