Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.
The following page has been changed by markt: http://wiki.apache.org/tomcat/FAQ/Security The comment on the change is: Add question list to start. ------------------------------------------------------------------------------ This FAQ section provides help with some security-related issues. If you hear of a vulnerability or its exploitation, please let us know on the [mailto:[EMAIL PROTECTED] [EMAIL PROTECTED] mailing list. === The Record === - Tomcat's security record is impeccable. There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue. There have been no documented cases of data loss or application crashes caused by an intruder. While there have been numerous analyses conducted on Tomcat, partially because this is easy to do with Tomcat's source code openly available, there have been only a few '''theoretical''' vulnerabilities found. All of those were addressed rapidly even though there were no documented cases of actual exploitation of these vulnerabilities. + There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue. There have been no documented cases of data loss or application crashes caused by an intruder. While there have been numerous analyses conducted on Tomcat, partially because this is easy to do with Tomcat's source code openly available, there have been only '''theoretical''' vulnerabilities found. All of those were addressed even though there were no documented cases of actual exploitation of these vulnerabilities. === Role of Customization === We believe, and the evidence suggests, that Tomcat is more than secure enough for most use-cases. However, like all other components of Tomcat, you can customize any and all of the relevant parts of the server to achieve even higher security. For example, the session manager implementation is pluggable, and even the default implementation has support for pluggable random number generators. If you have a special need that you feel is not met by Tomcat out of the box, consider these customization options. At the same time, please bring up your requirements on the user mailing list, where we'll be glad to discuss it and assist in your approach/design/implementation as needed. == Questions == + 1.

The admin and manager application do not provide a default login. Doing so is a security flaw. You need to edit $CATALINA_HOME/conf/tomcat-users.xml if you are using the default install.

By using the {{{RemoteHostValve}}} or {{{RemoteAddrValve}}}. Warning, these valves rely on accurate incoming ip addresses or hostnames. So they can fall victim to spoofing!

Fairly easily ;) See the Setup page in the docs for your tomcat release, and read [http://marc.theaimsgroup.com/?l=tomcat-user&m=108566020231438&w=2 this mailing list post] for a complete setup example with permissions etc. - ''' Has Tomcat's security been independently analyzed or audited?''' + [[Anchor(Q8)]]'''Has Tomcat's security been independently analyzed or audited?''' Yes, by numerous organizations and individuals, many times.
