This MIB module can also be used for configuration of certain objects, and anything that can be configured can be incorrectly configured, with potentially disastrous results. 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: o the pwVcMplsTable, pwVcMplsNonTeMappingTable and pwVcMplsTeMappingTable collectively contain objects to provision PW over MPLS tunnels. Unauthorized access to objects in these tables, could result in disruption of traffic on the network. The use of stronger mechanisms such as SNMPv3 security should be considered where possible. Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent which implements this MIB module. Administrators should consider whether read access to these objects should be allowed, since read access may be undesirable under certain circumstances. 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. These are the tables and objects and their sensitivity/vulnerability: o the pwVcMplsTable, pwVcMplsNonTeMappingTable, pwVcMplsTeMappingTable and pwVcMplsOutboundTable collectively show the PW over MPLS association. If an Administrator does not want to reveal this information, then these tables should be Pseudo Wire (PW) Over MPLS February 2004 Management Information Base considered sensitive/vulnerable. SNMP versions prior to SNMPv3 did not include adequate security. 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 module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework "see [RFC3410], section 8", including full support for the SNMPv3 cryptographic mechanisms "for authentication and privacy". 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. 9 IANA considerations As requested in the PW-TC-STD-MIB [PWTCMIB], PWE3 related standards track MIB modules should be rooted under the pwStdMIB subtree. The IANA is requested to assign { pwStdMIB 3 } to the PW-MPLS-STD-MIB module specified in this document. 10 References 10.1 Normative references [PWARCH] Bryant, S., et al, "PWE3 Architecture", work-in- progress.
