7. Security Considerations
Blocking unauthorized access to the HDSL2-SHDSL MIB via the element
management system is outside the scope of this document. It should
be noted that access to the MIB permits the unauthorized entity to
modify the profiles (section 6.4) such that both subscriber service
and network operations can be interfered with. Subscriber service
can be altered by modifying any of a number of service
characteristics such as rate partitioning and maximum transmission
rates. Network operations can be impacted by modification of
notification thresholds such as SES thresholds.
There are a number of managed objects in this MIB that may be considered to contain sensitive information. Access to these objects would allow an intruder to obtain information about which vendor's equipment is in use on the network. Further, such information is considered sensitive in many environments for competitive reasons. These identifying objects in the inventory group are: - hdsl2ShdslInvVendorID - hdsl2ShdslInvVendorModelNumber - hdsl2ShdslInvVendorSerialNumber - hdsl2ShdslInvVendorEOCSoftwareVersion - hdsl2ShdslInvStandardVersion - hdsl2ShdslInvVendorListNumber - hdsl2ShdslInvVendorIssueNumber - hdsl2ShdslInvVendorSoftwareVersion - hdsl2ShdslInvEquipmentCode - hdsl2ShdslInvVendorOther - hdsl2ShdslInvTransmissionModeCapability Therefore, it may be important in some environments to control read 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. It is recommended that the implementors 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] are recommended. It is then the customer/user's responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to those objects only to those principals (users) that have legitimate rights to access them. HDSL2-SHDSL layer connectivity from the xtuR will permit the subscriber to manipulate both the HDSL2-SHDSL link directly and the HDSL2-SHDSL embedded operations channel (EOC) for their own loop. For example, unchecked or unfiltered fluctuations initiated by the subscriber could generate sufficient notifications to potentially overwhelm either the management interface to the network or the element manager. It should be noted that interface indices in this MIB are maintained persistently. VACM data relating to these should be stored persistently.
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.8. Acknowledgments
The authors are deeply grateful to the authors of the ADSL LINE MIB (RFC 2662 [23]), Gregory Bathrick and Faye Ly, as much of the text and structure of this document originates in their documents. The authors are also grateful to the authors of FR MFR MIB (RFC 3020 [24]), Prayson Pate, Bob Lynch, and Kenneth Rehbehn, as the majority of the Security Considerations section was lifted from their document. The authors also acknowledge the importance of the contributions and suggestions regarding interface indexing structures received from David Horton of CITR. Other contributions were received from the following: Philip Bergstresser (Adtran) Steve Blackwell (Centillium) Umberto Bonollo (NEC Australia) Yagal Hachmon (RAD) Mark Johnson (Red Point) Sharon Mantin (Orckit) Moti Morgenstern (ECI) Raymond Murphy (Ericsson) Lee Nipper (Verilink) Randy Presuhn (BMC Software) Katy Sherman (Orckit) Mike Sneed (ECI) Jon Turney (DSL Solutions) Aron Wahl (Memotec) Bert Wijnen (Lucent) Michael Wrobel (Memotec)
