+## Reporting a Vulnerability
+
+We take security vulnerabilities seriously. If you discover a security issue in Ghost, please follow these steps:
+
+### For Security Researchers
+
+1. **DO NOT** create a public GitHub issue for security vulnerabilities
+2. Include detailed information about the vulnerability:
+   - Steps to reproduce
+   - Potential impact
+   - Suggested fix (if any)
+   - Your contact information
+
+### Response Timeline
+
+- **Initial Response**: Within 48 hours
+- **Assessment**: Within 7 days
+- **Fix Timeline**: Varies based on severity
+  - Critical: Within 7 days
+  - High: Within 14 days
+  - Medium: Within 30 days
+  - Low: Next release cycle
+
+### Disclosure Policy
+
+We follow responsible disclosure practices:
+
+1. Security researcher reports vulnerability privately
+2. We acknowledge receipt and begin investigation
+3. We develop and test a fix
+4. We prepare a security advisory
+5. We release the fix and publish the advisory
+6. Public disclosure after 90 days (or sooner if fix is available)
+
+### Security Best Practices for Users
+
+1. **Keep Ghost Updated**: Always use the latest version
+2. **Run with Minimal Privileges**: Don't run as Administrator unless necessary
+3. **Validate Detection Results**: Ghost is a tool to assist analysis, not replace human judgment
+4. **Secure Your Environment**: Ensure your analysis environment is properly isolated
+
+### Known Security Considerations
+
+1. **Memory Access**: Ghost requires elevated privileges to read process memory
+2. **False Positives**: Detection engines may flag legitimate software
+3. **Evasion**: Advanced malware may evade detection techniques
+4. **Performance Impact**: Intensive scanning may affect system performance
+
+### Security Features
+
+- Memory-safe Rust implementation
+- Input validation on all API boundaries
+- Minimal attack surface design
+- No network communication by default
+- Comprehensive error handling
+
+### Vulnerability Categories We're Interested In
+
+**High Priority:**
+- Memory safety violations
+- Privilege escalation
+- Code injection vulnerabilities
+- Authentication bypass
+- Sensitive data exposure
+
+**Medium Priority:**
+- Denial of service
+- Information disclosure
+- Logic flaws in detection algorithms
+
+**Out of Scope:**
+- Issues requiring physical access
+- Social engineering attacks
+- Third-party dependency vulnerabilities (unless exploitable through Ghost)
