Restrict access to Tomcat catalina.policy

中レベル 1自動tomcat

説明

The catalina.policy file is used to configure security policies for Tomcat. It is recommended that access to this file has the proper permissions to properly protect from unauthorized changes. $CATALINA_BASE/conf/catalina.policy must not match -perm /o+rwx,g+rwx,u+x 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.
