6.  Security Considerations

   In order to implement this MIB, a probe must capture all packets on
   the locally-attached network, including packets between third
   parties.  These packets are analyzed to collect network addresses,
   protocol usage information, and conversation statistics.  Data of
   this nature may be considered sensitive in some environments.  In
   such environments the administrator may wish to restrict SNMP access
   to the probe.

   A probe implementing this MIB is likely to also implement RMON [RFC
   2819], which includes functions for returning the contents of
   captured packets, potentially including sensitive user data or
   passwords.  It is recommended that SNMP access to these functions be
   restricted.

   There are a number of management objects defined in this MIB that
   have 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.

   SNMPv1 by itself is not a secure environment.  Even if the network
   itself is secure (for example by using IPSec), even then, 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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, 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.
