8. Security Considerations
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.
There are a number of managed objects in this MIB that may contain
sensitive information. These are:
read-create objects: ptopoConnRemoteChassisType
ptopoConnRemoteChassis ptopoConnRemotePortType
ptopoConnRemotePort ptopoConnAgentNetAddrType
ptopoConnAgentNetAddr ptopoConnIsStatic
ptopoConfigTrapInterval ptopoConfigMaxHoldTime
read-only objects: ptopoConnDiscAlgorithm
ptopoConnMultiMacSASeen ptopoConnMultiNetSASeen
ptopoConnLastVerifyTime ptopoLastChangeTime
notifications: ptopoConfigChange
These MIB objects expose information about the physical connectivity
for a particular portion of a network.
A network administrator may also wish to inhibit transmission of any
ptopoConfigChange notification by setting the ptopoConfigTrapInterval
object to zero.
It is thus important to control even GET 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 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.
