We'll start by removing these default applications and get Tomcat into secure TLS mode (Remember? SSL is deprecated!).

The default tomcat is configured in none SSL/TLS mode (plain text HTTP), and also includes defaults applications, An attacker could use these applications to gain access to other portions of the system. The default install is not secured and must be reviewed, especially if the instance is accessible over the web. Tomcat Out Of the Boxīy default tomcat can be deployed very quickly to start publishing web applications. It is important that these configuration changes are tested before making them in a live production system. What works well for one environment will not necessarily work for another. This portion is going to be determined by many factors, mainly to do with a particular environment. Locking down a Tomcat server is a balancing act: We don't want to overdo the securing to a point where users experience a slowdown in performance, or not able to access the applications altogether. It is evidently important to run an up to date version of your BMC products! Make sure to check for compatibility with BMC products using the Compatibility Matrix. Use the latest supported versions of Tomcat and Java.

Tomcat hardening and secure configuration

How the application works is most often independent from how the web server ant the Tomcat server are working. The web server receives the client's request, forwards it to the application, receives the response from the application, and finally forwards it to the client.Īt high level, it is crucially important to understand this architecture. That Servlet generates all the output in a Response object, and Tomcat sends this back as a response.Ī typical example, with a Web application, using Tomcat and the Apache web server: Tomcat receives a request, parses it into a Request object, and calls the Servlet. With Java, there are some small pieces of code to serve application requests, without having to worry about how the underlying protocol works (requests/responses in HTTP, FTP, SMTP or others).

At its core, Apache Tomcat is an open source servlet and JSP container.
