9.  Security Considerations

   There are no management objects defined in this MIB that have a MAX-
   ACCESS clause of read-write and/or read-create.  So, if this MIB is
   implemented correctly, then there is no risk that an intruder can
   alter or create any management objects of this MIB via direct SNMP
   SET operations.

   There are a number of managed objects in this MIB that may be
   considered to contain sensitive information in some environments.
   For example, the MIB identifies UDP ports on which processes are
   listening.  Although this information might be considered sensitive
   in some environments (i.e., to identify ports on which to launch
   denial-of-service or other attacks), there are already other ways of
   obtaining similar information.  For example, sending a random UDP
   packet to an unused port prompts the generation of an ICMP port
   unreachable message.

   Therefore, it may be important in some environments to control read
   access to these objects and possibly to even encrypt the values of
   these object when sending them over the network via SNMP.  Not all
   versions of SNMP provide features for such a secure environment.
   SNMPv1 by itself does not provide encryption or strong
   authentication.

   It is recommended that the implementors consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model [RFC2274] and the View-based Access
   Control Model [RFC2275] 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 those objects only to those principals
   (users) that have legitimate rights to access them.
