> Change files in CATALINA_HOME/conf to be readonly (440)
Initially these are 600 (except for tomcat-users.xml which is 644 and Tomcat keeps it that way). Is there a need to make them group-readable?
> Make sure tomcat user has ... write (220 - yes, only write) access to CATALINA_HOME/logs
This doesn't work. I think the best that can be done here is 750 or 700.

CATALINA_HOME/conf files updated to recommend chmod 400. tomcat-user.xml the same as tomcat doesn't write to it. Original file permissions for all these conf files were 600 when 5.5.20 was unpacked on a debian box.
CATALINA_HOME/logs directory updated to recommend chmod 300. Prevents tomcat user reading the logs within, but writing works fine for me - again after 5.5.20 was unpacked on a debian box.

Replacing Default Error Page
Why only restrict the default error page on java.lang.Exception? The more inclusive java.lang.Throwable would seem to be the better choice, as it would prevent leakage of stack traces in the event of a java.lang.Error.

Newer Tomcat branches
This page is hopelessly outdated for anyone working with the Tomcat 6 branch. We need to figure out the best way to document security measures for the different supported branches. Ken 10:25, 20 March 2009 (UTC)
