Validate and Sanitize All Input<\/h2>\n<p>Treat every request as hostile. Use parameterized queries or an ORM to stop SQL injection, and escape output to prevent cross-site scripting.<\/p>\n<ul>\n<li>Whitelist allowed characters and formats rather than blacklisting bad ones<\/li>\n<li>Validate on the server, never rely on client-side checks alone<\/li>\n<li>Set a Content Security Policy header to block inline script injection<\/li>\n<\/ul>\n<h2>2. Enforce Authentication and Authorization<\/h2>\n<p>Hash passwords with bcrypt or Argon2, and require multi-factor authentication for sensitive accounts. Check permissions on every request, not just in the UI.<\/p>\n<ul>\n<li>Use short-lived sessions with secure, HttpOnly cookies<\/li>\n<li>Deny by default; grant the minimum access needed<\/li>\n<li>Never expose sequential IDs that leak data or invite enumeration<\/li>\n<\/ul>\n<h2>3. Protect Data in Transit and at Rest<\/h2>\n<p>Force HTTPS with HSTS, use TLS 1.2 or higher, and encrypt sensitive fields in your database. Store secrets in a vault or environment manager \u2014 never in your repository.<\/p>\n<h2>4. Patch Dependencies and Log Activity<\/h2>\n<p>Run automated dependency scanning in CI, and enable structured logging with alerting on suspicious patterns like repeated login failures.<\/p>\n<h2>Conclusion<\/h2>\n<p>Security is a continuous process, not a one-time checklist. Start with input validation and access control, layer on encryption and monitoring, and review your posture every release.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Secure Your Web Application: A Practical Developer&#8217;s Guide Shipping a web app fast often means security gets postponed.
