Cybersecurity Essentials for Modern Applications

Security isn't optional. Here's what you need to protect your applications and users.

Authentication & Authorization

• Use OAuth 2.0 / OpenID Connect
• Implement MFA for sensitive operations
• JWT tokens with short expiration
• Role-based access control (RBAC)

Data Protection

• Encrypt data at rest and in transit
• Hash passwords with bcrypt/Argon2
• Sanitize all user inputs
• Use parameterized queries

Infrastructure Security

• Keep dependencies updated
• Use security headers (CSP, HSTS)
• Implement rate limiting
• Regular security audits
