4.10 Restrict access to Tomcat context.xml (Automated)

Profile Applicability

• Level 1

Description

The context.xml file is loaded by all web applications and sets certain configuration options. 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/context.xml care securely configured.

# cd $CATALINA_HOME/conf
# find context.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

Perform the following to restrict access to context.xml:

1. Set the ownership of the $CATALINA_HOME/conf/context.xml to tomcat_admin:tomcat.

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

2. Set the permissions for the $CATALINA_HOME/conf/context.xml to 600.

# chmod 600 $CATALINA_HOME/conf/context.xml

Default Value

The default permissions of context.xml are 600.
