Gets the "security" root mapping.
<p>
Example usage:
<pre>{@code
ConfiguratorRegistry registry = ConfiguratorRegistry.get();
ConfigurationContext context = new ConfigurationContext(registry);
CNode configNode = getSecurityRoot(context).get("GlobalJobDslSecurityConfiguration");}</pre>

@param context the configuration context
@return the "security" root mapping
@throws Exception something's not right...
