TMA-TOMCAT-4.6

Restrict access to Tomcat binaries directory

中レベル 1自動tomcat

説明

The Tomcat $CATALINA_HOME/bin directory contains executes that are part of the Tomcat run-time. It is recommended that the ownership of this directory be tomcat_admin:tomcat. It is also recommended that the permission on this directory deny read, write, and execute for the world (o-rwx) and deny write access to the group (g-w). $CATALINA_HOME/bin must not match -perm /o+rwx,g=w and must be owned by $TOMCAT_OWNER:$TOMCAT_GROUP; expects 0 findings. Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored. The expected owner/group are tomcat_admin:tomcat as in the benchmark; override with TOMCAT_OWNER / TOMCAT_GROUP.
