Restrict access to Tomcat catalina.properties (Scored)

Description

catalina.properties is a Java properties file which contains settings for Tomcat including class loader information, security package lists, and performance properties. It is recommended that access to this file properly protect from unauthorized changes.

Rationale

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

Audit Procedure

Perform the following to determine if the ownership and permissions on $CATALINA_HOME/conf/catalina.properties are securely configured.

# cd $CATALINA_HOME/conf/
# find catalina.properties -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

Perform the following to restrict access to catalina.properties:

1. Set the ownership of the $CATALINA_HOME/conf/catalina.properties to tomcat_admin:tomcat.

# chown tomcat_admin:tomcat $CATALINA_HOME/conf/catalina.properties

2. Set the permissions of the $CATALINA_HOME/conf/catalina.properties to 600.

# chmod 600 $CATALINA_HOME/conf/catalina.properties

Default Value

The default permissions of the top-level directories are 600.
