Protect the DDF from unauthorized access. As root, change the owner and group of critical DDF directories to the NON_ROOT_USER:

A NON_ROOT_USER (e.g., ddf) is recommended for installation.

chown -R NON_ROOT_USER $DDF_HOME $DDF_HOME/etc $DDF_HOME/data 
chgrp -R NON_ROOT_USER $DDF_HOME/etc $DDF_HOME/data 
chmod -R og-w $DDF_HOME/etc $DDF_HOME/data

Restrict access to sensitive files by ensuring that the only users with “group” permissions (e.g., ddf-group) have access to the following directories:

Execute the following as the above files (examples assume DDF_HOME is /opt/ddf):

chmod -R o /opt/ddf

As the the application owner (e.g., ddf user), restrict access to sensitive files:

chmod 640 /opt/ddf/etc
chmod 640 /opt/ddf/deploy

The system administrator must restrict certain directories to ensure that the application (user) cannot access directories that are not appropriate on the system. For example the NON_ROOT_USER should only have read access to /opt/ddf.
