Why You Need to Secure Tomcat<\/h2>

Apache Tomcat is a robust application server that includes many features available right out of the box.

There are many ways to improve Apache Tomcat security, and this blog is no replacement for a thorough dive into the possible ways in which you can do so. However, the tips below are a good starting point for people interested in hardening their Tomcat server deployment.\u00a0<\/p>
