8.  Security Considerations

   It is clear that this MIB module is potentially useful for monitoring
   CEP PWs.  This MIB can also be used for configuration of certain
   objects, and anything that can be configured can be incorrectly
   configured, with potentially disastrous results.

   There are number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read-create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  The pwCepTable, pwCepCfgTable, and pwCepFracTable contain objects
      to CEP PW parameters on a Provider Edge (PE) device.  Unauthorized
      access to objects in these tables could result in disruption of
      traffic on the network.  The use of stronger mechanisms such as
      SNMPv3 security should be considered where possible.
      Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent
      which implements this MIB module.  Administrators should consider
      whether read access to these objects should be allowed, since read
      access may be undesirable under certain circumstances.

   Some of the readable objects in this MIB module (i.e., objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive or
   vulnerable in some network environments.  It is thus important to
   control even GET and/or NOTIFY access to these objects and possibly
   to even encrypt the values of these objects when sending them over
   the network via SNMP.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  The pwCepTable, pwCepPerfCurrentTable, pwCepPerfIntervalTable, and
      pwCepPerf1DayIntervalTable collectively show the CEP pseudowire
      connectivity topology and its performance characteristics.  If an
      Administrator does not want to reveal this information, then these
      tables should be considered sensitive/vulnerable.

Top      Up      ToC       Page 65 
   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example, by using IPsec),
   there is no control as to who on the secure network is allowed to
   access and GET/SET (read/change/create/delete) the objects in this
   MIB module.

   It is RECOMMENDED that implementers consider the security features
   provided by the SNMPv3 framework (see [RFC3410], section 8),
   including full support for the SNMPv3 cryptographic mechanisms (for
   authentication and privacy).

   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.

9.  IANA Considerations

   The MIB module in this document uses the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
