Security Guidelines

Avoid Hardcoding Sensitive Data

Hardcoding sensitive data, such as API keys, passwords, or other credentials, is a significant security risk. Instead, use environment variables or secure secrets management tools to store and access such data. This approach minimizes the risk of accidental exposure in version control systems or during code sharing.

Best Practices:

• Use .env files or environment variables to store sensitive information.
• Leverage secrets management tools like AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault.
• Never commit sensitive data to version control systems.
• Regularly audit your codebase for any hardcoded sensitive information.

Validate and Sanitize User Input

Always validate and sanitize user input to prevent common vulnerabilities such as SQL injection, cross-site scripting (XSS), and command injection. Use libraries or frameworks that provide built-in protection mechanisms.

Best Practices:

• Use parameterized queries or ORM frameworks to prevent SQL injection.
• Escape or sanitize user input before rendering it in the UI to prevent XSS.
• Avoid directly executing user-provided input in commands or scripts.

Use Secure Communication

Ensure all communication between clients and servers is encrypted to protect data in transit.

Best Practices:

• Use HTTPS for all web traffic.
• Regularly update SSL/TLS certificates and use strong encryption protocols.
• Avoid using outdated or insecure protocols like HTTP or older versions of TLS.

Implement Proper Access Controls

Restrict access to sensitive resources and ensure users only have permissions necessary for their roles.

Best Practices:

• Follow the principle of least privilege.
• Use role-based access control (RBAC) or attribute-based access control (ABAC).
• Regularly review and update access permissions.

Keep Dependencies Updated

Outdated dependencies can introduce vulnerabilities into your project.

Best Practices:

• Regularly update libraries, frameworks, and tools to their latest stable versions.
• Use tools like Dependabot, npm audit, or Snyk to identify and fix vulnerabilities.
• Remove unused dependencies from your project.

Monitor and Log Security Events

Implement logging and monitoring to detect and respond to security incidents promptly.

Best Practices:

• Log authentication attempts, access to sensitive resources, and other critical events.
• Use centralized logging and monitoring tools like ELK Stack, Splunk, or Datadog.
• Regularly review logs for suspicious activity.
