How to Secure Apache Tomcat 8 in 15 Steps | UpGuard

This document outlines 15 practical steps to harden Apache Tomcat 8 out of the box, including running Tomcat as a non-root user, removing sample apps, locking down the shutdown port, disabling TRACE and the X-Powered-By header, disabling SSLv3 to prevent POODLE, restricting deployXML and automated deployment, choosing safer realms, recycling facades per request, enforcing read-only resources, disabling directory listings, enabling access logging, limiting or disabling the Manager app, and binding connectors to required interfaces, with references to OWASP and Tomcat security guides.
