Writing secure code is foundational to protecting applications from evolving security threats in production.

Input Validation and Sanitization

Always validate input on the server side to prevent injection and cross-site scripting attacks.

Sanitize outputs to avoid introducing security risks through rendering.

Authentication and Session Management

Use strong password policies and securely manage session tokens.

Implement multi-factor authentication where possible.

Error Handling and Logging

Avoid exposing sensitive information in error messages.

Log security-relevant events for audit and incident investigation.

Regular Code Reviews and Testing

Perform peer code reviews with a focus on security.

Incorporate automated security testing in CI pipelines.
