Rationale

Restricting access to this file will prevent local users from maliciously or inadvertently altering Tomcat's security policy.

# cd $CATALINA_HOME/conf/
# find server.xml -follow -maxdepth 0 \( -perm /o+rwx,g+rwx,u+x -o ! -user tomcat_admin -o ! -group tomcat \) -ls

The above command should not produce any output.

Remediation

# chown tomcat_admin:tomcat $CATALINA_HOME/conf/server.xml

2. Set the permissions of the $CATALINA_HOME/conf/server.xml to 600

# chmod 600 $CATALINA_HOME/conf/server.xml
