This element, which can be configured on a Host, Engine, or Context basis, will create a standard web server log file for traffic to any resources associated with it. To enable logging of network traffic in Tomcat, use the AccessLogValve component. Logs should be maintained on multiple levels - user access, application traffic, Tomcat internals, and OS/firewall, and a single process for reviewing and acting upon logs should be agreed upon by all system administrators. Maintaining logs once moving to production will help make sure an application which seems secure in development stays secure in the real world. In a development environment, it is not always obvious what kinds of malicious activity you should defend against. Well-maintained access logs are a vital tool in identifying security holes and sources of attack.
#Apache tomcat 8 what is it upgrade#
Always upgrade to the latest stable version of Tomcat as soon as possible. Apache also notifies community members of major security threats and patches through the Tomcat Announce mailing list. New bug fixes and security patches are added in every release, and new issues that may apply to your infrastructure are discussed on the Tomcat mailing lists. Stay CurrentĪs Tomcat is an active open source project, the easiest way to improve the security of your instance is to keep your version up to date and keep up with the Tomcat mailing lists. In this section, we'll look at things you can do to tune the security of your Tomcat instances to better match your access and functionality requirements. Use Tcat to easily enforce secure, consistent configurations across your entire infrastructure from an intuitive central console. This article covers three categories of security improvement: changes to Tomcat's internal configuration, changes to the operating system on which Tomcat is running, and best security practices for web applications.ĭon't take chances on your network's Security.

In order to implement these practices effectively, administrators should create a well-researched profile of the systems they oversee, and work from this clear set of needs to determine what security improvements can be made. In this article, we will provide an big picture overview of the security capabilities included in Tomcat. For example, although it is technically more secure to disable Tomcat's deployment capabilities when moving to production, for many organizations the desire to automate deployment supersedes the security benefit of disabling these features. As with any security scenario, Tomcat security is a matter of balancing ease of use and access with restriction and hardening of access. Starting from this baseline, there are additional measures that can be taken to make Tomcat as secure as possible for a given use case. Thus, the default installation of Tomcat can be said to be "fairly secure". Most vulnerabilities, both major and minor, are discovered by the Tomcat community itself or security researchers, and quickly patched. According to the official Apache Tomcat Wiki Pages, there has never been a reported case of actual damage or significant data loss due to a malicious attack on any Apache Tomcat instance.
