Secure Web Application Architecture

This secure web application architecture makes the main control points visible. Users enter through a combined web-application firewall and single-sign-on boundary, then reach the web application or API. Both services use an encrypted database, and the edge boundary writes to an audit log. It is appropriate for an early security review because it distinguishes the public entry point, application services, persistent data and audit evidence without claiming to be a full network design.
