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 RFC2574 [RFC2574] and the View-
based Access Control Model RFC2575 [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.
