Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines a set of managed objects for Simple Network
Management Protocol (SNMP) based management of the Baseline Privacy
Plus features of DOCSIS 1.1 and DOCSIS 2.0 (Data-over-Cable Service

RFC 4131 DOCSIS BPI Plus MIB September 2005
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.

Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
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]
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].
Green, et al. Standards Track [Page 4]
RFC 4131 DOCSIS BPI Plus MIB September 2005
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.
Green, et al. Standards Track [Page 79]
RFC 4131 DOCSIS BPI Plus MIB September 2005
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,
Green, et al. Standards Track [Page 80]
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]
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
old traffic, even when they are no longer in active use.
Green, et al. Standards Track [Page 82]
RFC 4131 DOCSIS BPI Plus MIB September 2005
Note that, not exempt to the same recommendations above, the CM BPI+
authorization protocol uses triple DES encryption, which offers
improved robustness in comparison to DES for CM authorization and TEK
re-key management.
