This document is the result of the efforts of the IETF AgentX Working
Group (WG).
This MIB is an evolution of the Subagent MIB by Bert Wijnen
(wijnen@vnet.ibm.com) which in turn was derived from the SMUX-MIB by
Marshall Rose [18].

7. Security Considerations
There is a single management object defined in this MIB that has a
MAX-ACCESS clause of read-write. This object 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.
Heintz, et al. Standards Track [Page 16]
RFC 2742 Agent X MIB January 2000
There is a single managed object in this MIB that may contain
sensitive information. This object is agentxSessionAdminStatus.
Setting agentxSessionAdminStatus to an inappropriate value can
effectively prevent access to management information, or provide
access to inappropriate information.
It is thus important to control even GET access to these objects and
possibly to even encrypt the values of these objects 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 RFC 2574 [12] and the View-based
Access Control Model RFC 2575 [15] 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/delete) them.
