ENIP
==============

The Ethernet Industrial Protocol (ENIP) is part of the Common Industrial Protocol (CIP). The Common Industrial Protocol (CIP) defines the object structure and specifies the message transfer. The ENIP Enforcer function applies the Deep Packet Inspection (DPI) function to the ENIP and CIP data stream. The Ethernet Industrial Protocol (ENIP) is used to monitor and control industrial automation equipment such as PLCs (Programmable Logic Controllers), sensors, and meters.

The device uses the ENIP Enforcer function to perform the DPI function on the data stream. The device performs the DPI function based on the values defined in the specified profiles. The device blocks the data packets that violate the specified profiles.

.. note::
    The ENIP Enforcer function performs the DPI function only on packets that contain an explicit request, and drops packets that contain an implicit request. An explicit request contains CIP message over TCP. An implicit request contains CIP message over UDP.

When the ENIP Enforcer profile is active, the device applies the profile to the data stream. 

The device permits only data packets containing the values specified in the following fields:

* Function type

* Sanity check

* Default object list

* Wildcard service codes

* Allow embedded PCCC (Programmable Controller Communication Commands)

The menu contains the following dialogs:

* ENIP Profile

* ENIP Object

You can find the ENIP enforcer at **Firewall → Enforcer → ENIP**.

ENIP Settings
**********************

**Enabled**
  Wheter the ENIP enforcer is active or not.

  Possible values:

  * **Enabled**

  * **Disabled** (default setting)

**Name**
  Name of the ENIP enforcer.

  Possible values:

  * **Character string** with 0..100 characters

**Description**
  Description of the ENIP enforcer.

  Possible values:

  * **Character string** with 0..250 characters

**Sanity Check**
  Activates/deactivates the plausibility check for the data packets.  

  Possible values:

  * **enabled** (default setting)

    The plausibility check is active.

    The device checks the plausibility of the data packets regarding format and specification.

    The device blocks the data packets that violate the specified profiles.

  * **disabled**

    The plausibility check is inactive.

**TCP Reset**
  Activates/deactivates the resetting of the TCP connection in case of a protocol violation or if the plausibility check detects an error.
    
  Possible values:

  * **enabled** (default setting)
    
    The resetting of the TCP connection is active.
    
    If the device identifies a protocol violation or detects a plausibility check error, then the device terminates the TCP connection. The device establishes the TCP connection again on receiving a new connection request.

  * **disabled**
  
    The resetting of the TCP connection is inactive.

**Debug**
  Activates/deactivates the debugging of the profiles.
  
  Possible values:
  
  * **enabled**
  
    Debugging is active.
  
    The device sends the reset packet along with the information related to the termination of TCP connection. The prerequisite is that in the TCP reset field the checkbox is marked.

  * **disabled** (default setting)
  
    Debugging is inactive.

**Allow embedded PCCC**
  Activates/deactivates DPI for PCCC messages encapsulated in data packets. PCCC messages are embedded within the Ethernet Industrial Protocol (ENIP). Activating this setting is useful when securing network traffic to and from PLC-5 and MicroLogix controllers.
  
  Possible values:
  
  * **enabled**
  
    DPI for PCCC messages is active.
      
  * **disabled** (default setting)
  
    DPI for PCCC messages is inactive.

**Preset**
  Preset of class IDs and service codes

  Possible values:

  * **Read Only**

    Assigns the class IDs for the read function.

  * **Read Write**
  
    Assigns the class IDs for the read/write functions.


  * **Any** (default setting)

    Assigns the class IDs for every function. 

    The device does not permit any subsequent changes in the Advanced *Class IDs* list.

  * **Advanced**

    Lets you specify user-defined class IDs.
