5.  Security Considerations

   There are a number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read-create.  It is
   possible for writes to these objects to have disruptive effects on
   network operation that range from invalid performance data to traffic
   interruptions.  Users of this MIB module must therefore be aware that
   support for SET operations in a non-secure environment without proper
   protection can have a negative effect on network operations.  The
   most sensitive objects are the read-write and read-create objects
   listed in the optIfOtnConfigCompl compliance statement that control
   the maximum number of TCM levels allowed (optIfOTMnTcmMax), automatic
   power reduction (optIfOTSnAprControl), transmitted trail trace
   (optIfOTSnTraceIdentifierTransmitted,
   optIfOTUkTraceIdentifierTransmitted,
   optIfODUkTtpTraceIdentifierTransmitted,
   optIfODUkTTraceIdentifierTransmitted), expected source/destination
   access point identifiers (optIfOTSnDAPIExpected,
   optIfOTSnSAPIExpected, optIfOTUkDAPIExpected, optIfOTUkSAPIExpected,

Top      Up      ToC       Page 168 
   optIfODUkTtpDAPIExpected, optIfODUkTtpSAPIExpected,
   optIfODUkNimDAPIExpected, optIfODUkNimSAPIExpected,
   optIfODUkTDAPIExpected, optIfODUkTSAPIExpected,
   optIfODUkTNimDAPIExpected, optIfODUkTNimSAPIExpected), trace
   identifier mismatch detection mode (optIfOTSnTIMDetMode,
   optIfOTUkTIMDetMode, optIfODUkTtpTIMDetMode, optIfODUkNimTIMDetMode,
   optIfODUkTTIMDetMode, optIfODUkTNimTIMDetMode), trace identifier
   mismatch consequent action (optIfOTSnTIMActEnabled,
   optIfOTUkTIMActEnabled, optIfODUkTtpTIMActEnabled,
   optIfODUkNimTIMActEnabled, optIfODUkTTIMActEnabled,
   optIfODUkTNimTIMActEnabled), threshold level for declaring a PM
   Second to be bad (optIfOTUkDEGThr, optIfODUkTtpDEGThr,
   optIfODUkNimDEGThr, optIfODUkTDEGThr, optIfODUkTNimDEGThr), threshold
   level for declaring a Degraded Signal defect (optIfOTUkDEGM,
   optIfODUkTtpDEGM, optIfODUkNimDEGM, optIfODUkTDEGM,
   optIfODUkTNimDEGM), whether the sink/source adaptation function is
   activated (optIfOTUkSinkAdaptActive, optIfOTUkSourceAdaptActive),
   whether Forward Error Correction is supported
   (optIfOTUkSinkFECEnabled), the application transported by the GCC
   entities (optIfGCC0Application, optIfGCC12Application), creating and
   deleting a conceptual row of a config table (optIfGCC0RowStatus,
   optIfODUkNimRowStatus, optIfGCC12RowStatus, optIfODUkTRowStatus,
   optIfODUkTNimRowStatus), whether the selected GCC overhead bytes are
   passed through or modified (optIfGCC12GCCPassThrough), TCM mode
   (optIfODUkTSinkMode), and provisioning of the sink/source LOCK signal
   (optIfODUkTSinkLockSignalAdminState,
   optIfODUkTSourceLockSignalAdminState), as these may cause traffic
   interruptions if improperly set.

   The readable objects in this MIB module (i.e., the objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive in
   some environments since, collectively, they provide information about
   the performance of interfaces in OTN equipment or networks and can
   reveal aspects of their configuration.  In such environments it is
   important to control even GET and NOTIFY access to these objects and
   possibly to encrypt the values of these objects when sending them
   over the network via SNMP.

   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) 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).

Top      Up      ToC       Page 169 
   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED that SNMPv3 be deployed and
   cryptographic security be enabled.  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.

   Nathan Kohn initiated the concept, then gathered and coordinated the
   team that led to the initial version of the MIB.  Mark Stewart/Brian
   Teer wrote sections on use of interface tables, reviewed the MIB
   Object Definitions for SNMP SMIv2 compliance, and wrote the PM
   sections in working with G.7710/Y.1701.  Anni Huynh wrote the initial
   MIB definitions for the OTN interface.  Tom Rutt wrote the summary
   section on the Structure of the MIB.  Rishi Grover contributed to the
   objects to monitor banded amplifiers.  Kam Lam wrote the sections on
   Optical Networking Terminology and the OTN layers configuration
   parameters.  He was the editor for the last several versions of this
   document.

   Thanks to Maarten Vissers for providing insight into Optical
   Networking concepts.  Thanks to Lakshmi Raman and Moshe Rozenblit for
   reviewing and commenting on a preliminary version of the document.

   Special thanks to C. Mike Heard for providing a top notch doctor
   review and many helpful suggestions to improve the MIB.
