Tomcat 5.5.23 document read Tips 6-Security Manager

This article describes security and is not very useful to us. For example, if we build a machine and install Tomcat and run some applications in it, if a user writes a JSP like this:

<% SYSTEM. Exit (1); %>

This JSP will cause Tomcat to exit. Because the entire JVM has exited. This document describes how Tomcat configures a policy file to restrict the resources and permissions that users can use.

For more information, see the document itself. The policy file that comes with Tomcat should already have a good policy file.
