8. Security Considerations
There are management objects (radiusAccServConfigReset) 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. These are:
radiusAccServConfigReset
This object can be used to reinitialize the persistent state of
any server. When set to reset(2), any persistent server state
(such as a process) is reinitialized as if the server had just
been started. Depending on the server implementation details,
this action may or may not interrupt the processing of pending
request in the server. Abuse of this object may lead to a Denial
of Service attack on the server.
There are a number of managed objects in this MIB that may contain
sensitive information. These are:
radiusAccClientIPAddress
This can be used to determine the address of the RADIUS accounting
client with which the server is communicating. This information
could be useful in mounting an attack on the accounting client.
radiusAccClientInetAddress
This can be used to determine the address of the RADIUS accounting
client with which the server is communicating. This information
could be useful in mounting an attack on the accounting client.
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.
SNMP versions prior to SNMPv3 do not provide a secure environment.
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) the objects in this
