Cybersecurity for developers: best practices

·1 min read

Security by design

Security shouldn't be an afterthought. Incorporate it from the design phase of your application.

Secret management

Never commit API keys, tokens, or passwords to the repository. Use environment variables or services like Vault, AWS Secrets Manager, or Doppler.

Input validation

All user input is potentially malicious. Validate, sanitize, and parameterize all inputs. SQL Injection remains one of the most exploited vulnerabilities.

Secure authentication

Implement MFA, use OAuth 2.0 / OIDC for authentication, and store passwords with bcrypt or Argon2.

API security

Use rate limiting, validate JWT tokens, implement rotating API keys, and document your API with OpenAPI including security schemes.

Secure dependencies

Use npm audit, pip audit, or trivy to scan dependencies for vulnerabilities. Keep libraries updated.

Logging and monitoring

Log security events without sensitive data. Implement alerts for suspicious patterns.

Conclusion

Cybersecurity is every developer's responsibility. At Vynta we apply security best practices in every line of code we write.
