8. Security Considerations
This MIB relates to a system that will provide network connectivity and packet-forwarding services. As such, improper manipulation of the objects represented by this MIB may result in denial of service to a large number of end-users. There are a number of management objects defined in this MIB module with 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 the tables and objects and their sensitivity/vulnerability: The following tables and objects in the RBRIDGE-MIB can be manipulated to interfere with the operation of RBridges: o rbridgeBaseUniMultipathEnable affects the ability of the RBridge to route unicast traffic over multiple paths, and rbridgeBaseMultiMultipathEnable affects the ability of the RBridge to route multi-destination traffic over multiple paths. o rbridgeBasePortTable contains a number of objects that may affect network connectivity. Actions that may be triggered by manipulating objects in this table include disabling of an RBridge port, discarding of native packets, disabling learning, and others. o rbridgeEsadiTable contains objects that affect the operation of the ESADI protocol used for learning, and manipulation of the objects contained therein can be used to confuse the learning ability of RBridges. o rbridgeDtreePriority can affect computation of distribution trees within an RBridge campus, thereby affecting the forwarding of multi-destination traffic. o rbridgeTrillMinMtuDesired can affect the size of packets being used to exchange information between RBridges. Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over
the network via SNMP. For example, access to network topology and RBridge attributes can reveal information that should not be available to all users of the network. SNMP versions prior to SNMPv3 did not include adequate security. 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 MIB module. Implementations SHOULD provide the security features described by the SNMPv3 framework (see [RFC3410]), and implementations claiming compliance to the SNMPv3 standard MUST include full support for authentication and privacy via the User-based Security Model (USM) [RFC3414] with the AES cipher algorithm [RFC3826]. Implementations MAY also provide support for the Transport Security Model (TSM) [RFC5591] in combination with a secure transport such as SSH [RFC5592] or TLS/DTLS [RFC6353]. Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module 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. For other RBridge security considerations, see [RFC6325].9. IANA Considerations
