1.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

2.  Overview

   This MIB module (BPI+ MIB) provides a set of objects required for the
   management of the Baseline Privacy Interface Plus features of DOCSIS
   1.1 and DOCSIS 2.0 Cable Modem (CM) and Cable Modem Termination
   System (CMTS).  The specification is derived from the operational
   model described in the DOCSIS Baseline Privacy Interface Plus
   Specification [DOCSIS].

   DOCSIS Baseline Privacy Plus is composed of four distinct functional
   and manageable areas:

   o  Key exchange and data encryption

   o  Cable modem authentication

   o  Multicast encryption

   o  Authentication of downloaded software images

   This MIB module is an extension of the DOCSIS 1.0 Baseline Privacy
   MIB module [RFC3083] (BPI MIB), which is derived from the Operational
   model described in the DOCSIS Baseline Privacy Interface
   Specification [DOCSIS-1.0].  The original Baseline Privacy MIB
   structure has mostly been preserved in the Baseline Privacy Plus MIB.
   Please note that the referenced DOCSIS specifications only require
   that Cable Modems process IPv4 customer traffic.  Design choices in
   this MIB module reflect those requirements.  Future versions of the
   DOCSIS specifications are expected to require support for IPv6 as
   well.

      NOT","SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
      in this document are to be interpreted as described in BCP 14, RFC
      2119 [RFC2119].

2.1.  Structure of the MIB

   This MIB module is structured into several tables and objects.

2.1.1.  Cable Modem

   o  The docsBpi2CmBaseTable contains authorization key exchange
      information for one CM MAC interface.

   o  The docsBpi2CmTEKTable contains traffic key exchange and data
      encryption information for a particular security association ID of
      the cable modem.

   o  Multicast Encryption information is maintained under
      Docsbpi2CmMulticastObjects.  There is currently one multicast
      table object that manages IP multicast encryption,
      docsBpi2CmIpMulticastMapTable.

   o  Digital certificates used for cable modem authentication are
      accessible via docsBpi2CmDeviceCertTable.

   o  Cryptographic suite capabilities for a CM MAC are maintained in
      the docsBpi2CmCryptoSuiteTable.

2.1.2.  Cable Modem Termination System

   o  The docsBpi2CmtsBaseTable contains default settings and summary
      counters for the cable modem termination system.

   o  The DocsBpi2CmtsAuthTable contains Authorization Key Exchange
      information for each CM MAC interface, as well as data from CM
      certificates used in cable modem authentication.

   o  The docsBpi2CmtsTEKTable contains traffic key exchange and data
      encryption information for a particular security association ID.

   o  Multicast Encryption information is maintained under
      Docsbpi2CmtsMulticastObjects.  There are currently two multicast
      table objects.  The Table docsBpi2CmtsIpMulticastMapTable is





Green, et al.               Standards Track                     [Page 3]
^L
RFC 4131                  DOCSIS BPI Plus MIB             September 2005


      specifically designed for IP multicast encryption, whereas
      docsBpi2CmtsMulticastAuthTable is meant to manage all multicast
      security associations.

         In particular, the table docsBpi2CmtsIpMulticastMapTable
         defines the object docsBpi2CmtsIpMulticastMask, which could be
         a non-contiguous netmask; this is why the object syntax is
         based on the INET-ADDRESS-MIB MIB Module [RFC4001] Textual
         Convention InetAddress instead of InetAddressPrefixLength.

         This is to facilitate the assignment of same DOCSIS Security
         Association ID (SAID) to one or more IPv6 multicast group IDs
         matching one or more IPv6 multicast scope types within an entry
         in this table.  For example, multicast scopes labeled
         "unassigned" [RFC3513] may be allocated by administrators to a
         particular SAID, regardless of their multicast scope; such
         mapping transient multicast group 'Y' to SAID 'z' for ANY
         multicast scope.  The non-contiguous netmask will be FF10:Y.
         See [RFC3513] for details on IPv6 multicast addressing.

   o  DocsBpi2CmtsCertObjects contains 2 manageable tables: one for
      provisioned cable modem certificates and one for certification
      authority certificates.

2.1.3.  Common

   o  The docsBpi2CodeDownloadControl objects manage the authenticated
      software download process for a given device.

2.2.  Relationship of BPI+ and BPI MIB Modules

   This section describes the relationship between the BPI+ MIB module
   defined in this document and the BPI MIB module defined in RFC 3083
   [RFC3083].  The BPI+ protocol interface is an enhancement to the BPI
   protocol, and it is a distinct protocol from BPI.  The associated
   BPI+ managed objects should be considered separate from the BPI MIB
   objects defined in RFC 3083.

   DOCSIS 1.1 and 2.0 systems implement both the BPI+ and BPI protocols
   to be backward compatible with 1.0 systems.  For more information
   regarding the interoperability between BPI and BPI+ compliant
   systems, refer to appendix C of the DOCSIS BPI+ specification
   [DOCSIS].  For MIB modules requirements, refer to section 4.6.1,
   Figure 9, of the DOCSIS 1.1 OSSI specification [DOCSIS-1.1] and to
   section 7.6.1, Tables 7-9, of the DOCSIS 2.0 OSSI specification
   [DOCSIS-2.0].

2.3.  BPI+ MIB Module Relationship with the Interfaces Group MIB

   The BPI+ MIB module is the management framework of Baseline Privacy
   Plus Interface Specification [DOCSIS], which provides the MAC layer
   (Media Access Control) security services of DOCSIS through the
   Baseline Privacy Key Management (BPKM) protocol.  The BPI+ MIB module
   objects are organized as extensions of the Radio Frequency (RF)
   Interface Management [RFC2670].

   The MIB table structures of this MIB Module are extensions of the
   DOCSIS CATV (Community Antenna Television) MAC layer interface
   (DocsCableMaclayer by [IANA]).  In particular, the provisions of the
   Interface Group MIB [RFC2863] for counter discontinuities and system
   re-initialization apply to CM and CMTS to validate the difference
   between two consecutive counter polls.

   All BPI+ MIB module counters are 32 bits and are based on the minimum
   time to wrap up considerations of [RFC2863] and their possible
   frequency occurrence as BPI+ FSM (Finite State Machine) event
   counters.  See [DOCSIS] for BPI+ FSM parameter guidelines.

7.  Security Considerations

   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 objects, if SNMP SET maliciously, could constitute
     denial of service or theft of service attacks or compromise the
     intended data privacy of users:

   Objects related to the Baseline Privacy Key Management (BPKM)

      docsBpi2CmAuthReset,
      docsBpi2CmtsAuthCmReset,
      docsBpi2CmtsTEKReset:
          These objects are used for initiating a re-key process.  A
          malicious massive SET attack may cause CMTS processing
          overload and may compromise the service.

      docsBpi2CmtsDefaultAuthLifetime,
      docsBpi2CmtsDefaultTEKLifetime,
      docsBpi2CmtsAuthCmLifetime,
      docsBpi2CmtsTEKLifetime:
          To minimize the risk of malicious or unintended short periods
          of time when key updates may lead to degradation or denial of
          service, implementers are encouraged to follow these objects'
          range constraints, as defined in the docsBpi2CmtsCompliance
          MODULE-COMPLIANCE clause for operational deployments.

      docsBpi2CmtsDefaultSelfSignedManufCertTrust:
          A malicious SET in a self-signed certificate as reject
          message, which may constitute denial of service.  This object
          is designed for testing purposes; therefore, it is not
          RECOMMENDED for use in commercial deployments [DOCSIS].
          Administrators can make use of View-based Access Control
          (VACM) introduced in section 7.9 of [RFC3410] to restrict
          write access to this object.

      docsBpi2CmtsCheckCertValidityPeriods:
          A malicious SET in this object that enables the period
          validity and a wrong clock time in the CMTS could cause denial
          of service, as CM authorization requests will be rejected.

      For more details in the validation of CM certificates, refer to
      section 9 of [DOCSIS] .

   Objects related to the CM only:

      Objects in docsBpi2CmDeviceCertTable

      docsBpi2CmDeviceCmCert:
          This object is not harmful, considering that a CM received a
          Certificate during the manufacturing process.  Therefore, the
          object access becomes read-only.  See the object DESCRIPTION
          clause in section 3 for details.

      Objects for Secure Software Download in table
      docsBpi2CodeDownloadControl:

      docsBpi2CodeCvcUpdate:
          A malicious SET on this object may not constitute a risk,
          since the CM holds the DOCSIS root key to verify the CVC
          authenticity.  The operator, if configured, could receive a
          notification for event occurrences, which may lead to
          detecting the source of the attack.  Moreover, [DOCSIS]
          recommends that CMs CVC be regularly updated to minimize the
          risk of potential code-signing keys being compromised (e.g.,
          by configuration file).

      Objects related to the CMTS only:

      Objects in docsBpi2CmtsProvisionedCmCertTable and
      docsBpi2CmtsCACertTable containing CM Certificates and Certificate
      Authority information, respectively:

      docsBpi2CmtsProvisionedCmCertTrust,
      docsBpi2CmtsProvisionedCmCertStatus,
      docsBpi2CmtsProvisionedCmCert,
      docsBpi2CmtsCACertStatus,
      docsBpi2CmtsCACert:
          A malicious SET on these objects may constitute a denial of
          service attack that will be experienced after the CMs perform
          authorization requests.  It does not affect CMs in the
          authorized state.

      Objects in multicast tables docsBpi2CmtsIpMulticastMapTable and
      docsBpi2CmtsMulticastAuthTable:

      docsBpi2CmtsIpMulticastAddressType,
      docsBpi2CmtsIpMulticastAddress,
      docsBpi2CmtsIpMulticastMaskType,

RFC 4131                  DOCSIS BPI Plus MIB             September 2005


      docsBpi2CmtsIpMulticastMask,
      docsBpi2CmtsIpMulticastSAId,
      docsBpi2CmtsIpMulticastSAType:
          Malicious SET on these objects may cause misconfiguration,
          causing interruption of the users' active multicast
          applications.

      docsBpi2CmtsIpMulticastDataEncryptAlg,
      docsBpi2CmtsIpMulticastDataAuthentAlg:
          Malicious SETs on these objects may create service
          misconfiguration, causing service interruption or theft of
          service if encryption algorithms are removed for the multicast
          groups.

      docsBpi2CmtsIpMulticastMapControl,
      docsBpi2CmtsMulticastAuthControl:
          Malicious SETs on these objects may remove and/or disable
          customers and/or multicast groups, causing service disruption.
          This may also constitute theft of service by authorizing non-
          subscribed users to multicast groups or by adding other
          multicast groups in the forward path.

   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:

      Objects in docsBpi2CmBaseTable, docsBpi2CmTEKTable,
      docsBpi2CmtsBaseTable, docsBpi2CmtsAuthTable,
      docsBpi2CmtsTEKTable, docsBpi2CmtsProvisionedCmCertTable, and
      docsBpi2CmtsCACertTable:
          If this information is accessible, attackers may use it to
          distinguish users configured to work without data encryption
          (e.g., docsBpi2CmPrivacyEnable) and to know current Baseline
          Privacy parameters in the network.

      Objects in docsBpi2CmIpMulticastMapTable and
      docsBpi2CmtsMulticastAuthTable:
          In addition to the vulnerabilities around BPI plus multicast
          objects described in the previous part, the read-only objects
          of this table may help attackers monitor the status of the
          intrusion.






Green, et al.               Standards Track                    [Page 81]
^L
RFC 4131                  DOCSIS BPI Plus MIB             September 2005


      Objects in docsBpi2CodeDownloadControl:
          In addition to the vulnerability of the read-write object
          docsBpi2CodeCvcUpdate, attackers may be able to monitor the
          status of a denial of service using Secure Software Download.

   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.

   BPI+ Encryption Algorithms:

   The BPI+ Traffic Encryption Keys (TEK) defined in the DOCSIS BPI+
   specification [DOCSIS] use 40-bit or 56-bit DES for encryption (DES
   CBC mode).  Currently, there is no mechanism or algorithm defined for
   data integrity.

   Due to the DES cryptographic weaknesses, future revisions of the
   DOCSIS BPI+ specification should introduce more advanced encryption
   algorithms, as proposed in the DocsBpkmDataEncryptAlg textual
   convention, to overcome the progress in cheaper and faster hardware
   or software decryption tools.  Future revisions of the DOCSIS BPI+
   specification [DOCSIS] should also adopt authentication algorithms,
   as described in the DocsBpkmDataAuthentAlg textual convention.

   It is important to note that frequent key changes do not necessarily
   help in mitigating or reducing the risks of a DES attack.  Indeed,
   the traffic encryption keys, which are configured on a per cable
   modem basis and per BPI+ multicast group, can be utilized to decrypt
