   Any security-related (properties that begin with <code class="ph codeph">security-</code>) configuration properties that are normally configured in <code class="ph codeph">gemfire.properties</code> can be moved to a separate <code class="ph codeph">gfsecurity.properties</code> file. Placing these configuration settings in a separate file allows you to restrict access to security configuration data. This way, you can still allow read or write access for your <code class="ph codeph">gemfire.properties</code> file.
