• Medium Severity: 30 days to patch release
• Low Severity: 90 days to patch release

Security Measures

Infrastructure Security

• Dependency Scanning: Automated scanning for vulnerable dependencies using npm audit and Snyk
• Container Security: Docker image scanning for vulnerabilities using Trivy
• Secrets Management: HashiCorp Vault for secure credential storage (never in code)
• Network Security: Firewall rules and network segmentation
• Encryption: All data encrypted in transit (TLS 1.3) and at rest (AES-256)

Code Security

• Code Reviews: All changes require review by multiple team members
• Static Analysis: Automated security scanning in our CI pipeline
• Dynamic Analysis: Regular penetration testing and vulnerability assessments
• Security Training: Regular security awareness training for developers
• Secure Coding Practices: Adherence to OWASP Top 10 and industry best practices

Access Control

• Role-Based Access: Principle of least privilege for all systems
• Multi-Factor Authentication: Required for all administrative access
• Audit Logging: Comprehensive logging of all access and modifications
• Regular Audits: Periodic access reviews and permission audits
• Session Management: Secure session handling with proper timeouts

Data Protection

• Data Encryption: AES-256 encryption for sensitive data
• Data Minimization: Collection of only necessary data
• Data Retention: Defined retention policies and secure deletion
• Backup Security: Encrypted backups with access controls
• Privacy by Design: Privacy considerations integrated into all features

Security Best Practices

For Developers

• Never commit secrets or credentials to the repository
• Use environment variables for all configuration
• Validate all user inputs on both client and server
• Sanitize data before rendering or storing
• Follow the principle of least privilege for all operations
• Keep dependencies up to date and monitor for vulnerabilities
• Enable two-factor authentication on your GitHub account
• Use parameterized queries to prevent SQL injection
• Implement proper error handling without exposing sensitive information
• Regularly review and update security configurations

For Deployments

• Use the latest stable versions of all components
• Implement proper firewall rules and network segmentation
• Enable encryption for all data in transit and at rest
• Regularly update and patch all system components
• Monitor and log all access and security events
• Implement backup and recovery procedures
• Conduct regular security assessments and penetration testing
• Follow the principle of least privilege for all services
• Use secure configuration for all components
• Implement proper access controls and authentication

Compliance

Standards and Frameworks

• OWASP Top 10: Adherence to OWASP security principles
• ISO 27001: Information security management
