It is also recommended that the permission on this directory eny read, write, and execute for the world (o-rwx) and deny write access to the group (g-w).


Restricting access to these directories will prevent local users from maliciously or inadvertently affecting the integrity of web applications.


Perform the following to restrict access to Tomcat webapps directory:

Set the ownership of the $CATALINA_HOME/webapps to tomcat_admin:tomcat.

# chown tomcat_admin:tomcat $CATALINA_HOME/webapps

Remove read, write, and execute permissions for the world.

# chmod g-w,o-rwx $CATALINA_HOME/webapps

Default Value:

The default permissions of the top-level directories are 770.
