Cable Modem Access Protection
Cable Modem Access Protection is a security right for cable modem gateway users
that prevents access to their PCs by hackers, other users, or devices from the
network side of the cable modem gateway network. This right provides CPE access
protection as if the unit was physically disconnected from the cable modem gateway
network.
Cable Modem Access Protection provides the following features:
Prevents network side access, when enabled by the user, to a CPE device
Provides a convenient Web browser-based interface
Allows local area network operation when access protection mode is enabled
Disables automatically using the Reset switch on the cable modem gateway back
panel
Network Control of the Cable Modem Access Protection Feature
(Active or Inactive)
To support the ability for the cable modem gateway network operator to offer this
feature as a premium or “for fee” service, the network administrator has the ability
to activate (set to Active) or deactivate (set to Inactive) the Cable Modem Access
Protection right in any (or all) cable modems. The network administrator uses a
custom MIB setting in the cable modem configuration file or an SNMP transaction to
perform this task.
Note:
The factory or default setting for this feature is Inactive (deactivated).
Basic Functionality
When the Network Administrator sets the cable modem gateway access protection
to Active, the end user has complete control over the settings of the feature. These
user-controlled settings are as follows:
Enable
(access protection enabled manually)
Disable
(access protection disabled manually)
Automatic
(access protection controlled automatically)
Important:
Do not confuse the capability of the CPE to control the setting (Enable /
Disable / Automatic) and the Cable Modem Access Protection right. The right is the
Network Administrator’s ability to activate or deactivate the availability of the
feature on the cable modem gateway.
