9. Security Considerations
The following security matters should be considered when implementing
this MIB.
1) Blocking unauthorized access to the ADSL 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.
Ly & Bathrick Standards Track [Page 32]
RFC 3440 ADSL Line Extension MIB December 2002
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
modifying notification thresholds such as Signal-to-Noise Ratio
(SNR) margins.
2) SNMPv1 by itself is such an insecure environment. Even if the
network itself is secure (for example by using IPSec), there is no
control over who on the secure network is allowed to access and
GET (read) the objects in this MIB. 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 STD 62, RFC 3414 [RFC3414] and the View-based
Access Control Model STD 62, RFC 3415 [RFC3415] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to only those objects, and to those
principals (users) that have legitimate rights to access them.
3) The profile mechanism presented in this document requires specific
attention. The implementor of this MIB has a choice of
implementing either 'static' or 'dynamic' profiles. This decision
must be consistent with the implementation of RFC 2662.
In the case of 'static' profiles, the elements of the profile are
read-write, as opposed to read-create when 'dynamic' profiles are
implemented:
- adslConfProfileLineType,
- adslAtucThreshold15MinFailedFastR,
- adslAtucThreshold15MinSesL,
- adslAtucThreshold15MinUasL,
- adslAturThreshold15MinSesL, and
- adslAturThreshold15MinUasL.
This decision also impacts the mechanics of the index,
adslLineConfProfileDualLite. When 'static' profiles are
implemented, its value is algorithmically set by the system and
its value is based on the ifIndex. Hence it is not guaranteed
across system reboots. Similar to the handling of
adslLineConfProfile [RFC2662], the implementor of this MIB must
ensure that the profile object values associated with these
indices are maintained across system reboots.
Ly & Bathrick Standards Track [Page 33]
RFC 3440 ADSL Line Extension MIB December 2002
In the case of dynamic profiles, this object is set by the SNMP
manager. The implementor of this MIB may want to provide a view
of the profile on a customer-by-customer standpoint, but should be
cautious of the dynamic nature of these objects.
4) ADSL layer connectivity from the ATU-R will permit the
subscriber to manipulate both the ADSL link directly and the ADSL
overhead control channel(AOC)/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. Other attacks
affecting the ATU-R portions of the MIB may also be possible.
