Hello, as a beginner developer, how can I systematically scan for security vulnerabilities in my project? Apart from automated tools, what methods can I apply for manual checks? For example, what should I pay attention to during code reviews? Thanks!
What are the methods for vulnerability scanning?

For manual security checks, there are several proven approaches that go beyond purely tool-based scans. The most important step is thorough **code reviews through structured walkthroughs**, where you look for classic vulnerabilities like SQL injection, Cross-Site Scripting (XSS), or insecure direct object references. Pay special attention to **unvalidated user inputs** that are used without sanitization or parameterization—here, the OWASP Top 10 serves as a useful checklist. Another key focus should be on **authentication and session management flaws**, such as weak password policies or missing rate limits for login attempts.
An often underestimated method is **manual penetration testing with proxy tools** like Burp Suite (Community Edition) or OWASP ZAP. With these, you can intercept, manipulate, and test live requests for unexpected behavior, particularly on API endpoints or file uploads. Document every step—this not only improves traceability but also sharpens your awareness of common attack vectors like HTTP header injection or deserialization-based attacks (e.g., in Java applications). Supplement this with **document research**, such as cross-referencing dependencies (e.g., via `npm audit` or `snyk`) against known CVEs.
