Step-by-step guide to using Claude Code securely and protecting your applications.
Claude Code Security Context
Claude Code uses Anthropic's Constitutional AI approach, which aims to be helpful while avoiding harm. However, all AI-generated code should still be reviewed for security vulnerabilities.
Security Checklist
Review AI-generated code
CriticalClaude Code's Constitutional AI approach produces thoughtful code, but always review for security.
Understand data handling
CriticalReview Anthropic's data policies and understand how your code is processed.
Exclude sensitive files
CriticalConfigure which files Claude Code can access to protect secrets.
Audit secrets in codebase
CriticalEnsure API keys and credentials aren't exposed to AI analysis.
Review dependency suggestions
CriticalAudit any packages suggested for security vulnerabilities.
Test generated authentication
CriticalVerify auth flows work correctly and securely.
Validate input handling
CriticalCheck that generated code properly validates user inputs.
Review error handling
CriticalEnsure errors don't expose sensitive information.
Check API integrations
CriticalVerify API keys are stored in environment variables.
Audit database queries
Check for SQL injection vulnerabilities in generated code.
Review file operations
Ensure file handling is secure and validated.
