Cybersecurity for Web SCADA: Reverse Proxies, TLS 1.3, CSP & MFA Hardening

Harden browser-based SCADA systems against cyber threats: configuring Nginx/HAProxy reverse proxies, enforcing TLS 1.3 certificates, Content Security Policy headers, and Okta MFA.

  • Never expose a SCADA gateway port directly to the internet; always terminate traffic in a DMZ reverse proxy.
  • Enforce TLS 1.3 encryption across all client browser sessions with strict HTTP Strict Transport Security (HSTS).
  • Integrate plant user logins with enterprise Single Sign-On (SSO) to enforce immediate revocation upon employee termination.
