For an 
                  		  enterprise server region, you can create a secure Communications Process control listener to encrypt the communications it handles: 
                  		
               
 
               		
                
                  		  
                  - In 
                     			 ESCWA, click 
                     			 Native. 
                     		  
                  
- In the navigation pane, expand 
                     			 Directory Servers, and then select your 
                     			 enterprise server region. 
                     		  
                  
- Click 
                     			  
                     		  
                  
- Click 
                     			 Communications Processes that corresponds to the server which you want to secure. 
                     		  
                  
- In the 
                     			 Communications Server Properties, click 
                     			 Configure to expand the list of properties. 
                     		  
                  
- Click 
                     			 TLS Settings.
                     		  
                  
- Click 
                     			 Enable TLS.
                     		  
                  
- In the 
                     			 Certificate File field, type the absolute path to the certificate file. 
                     		  
                  
- In the 
                     			 Keyfile field, type the absolute path to the keyfile. 
                     			 
                     Note: The keyfile must reference a file containing the passphrase. See 
                        				To Configure the Passphrase in a File for more information. 
                        			 
                      
- Click 
                     			 Apply. 
                     		  
                  
 If the enterprise server is configured to use a security manager, then in addition to enabling TLS (SSL) for the Communications
                  Process control listener, you can set resource access control rules for some Communications Process features. See 
                  		  Resource Classes for Communications Server for more information.
