Fraud Prevention in DOCSIS Networks: Security Roles

In this final post on fraud protection in DOCSIS networks, let’s examine how security roles in the Incognito solution can be utilized to prevent service theft.

Administrative Security

Administrator Accounts

Administrator accounts enable you to set up users that function in different assigned security roles:

  • Super User: Super user accounts always have access to all aspects of the DHCP service configuration. This access cannot be removed or restricted by any other security settings or Access Control Lists.

  • Account Administrator: Only super users and account administrators are able to add, modify or delete existing accounts, with one exception: every user can change his or her own password from the File –> Change Password menu item

  • Service Manager: Only super users and users with this attribute set can access service configuration and operations

In addition to the security roles, the DHCP service also supports specific database access privileges. User can be set to have either “read-only” or “manage” access to specific service features.

Fraud Prevention in DOCSIS Network: Securing Your Platform

Enabling additional features in the Incognito fraud protection solution will go a long way to securing your DOCSIS network from service theft.

Anti-Roaming

Anti-Roaming devices enable you to restrict roaming on particular devices attached to the network. Anti-Roaming only has an effect for IP phishing/device ID cloning, when the cloned MAC is on a different CMTS. In the majority of cases, the cloned MAC will be on the same CMTS, as it’s likely the person cloning the MAC will be on the same local network by using a network sniffer to obtain the MAC.

Fraud Prevention in DOCSIS Network: Data Sharing

We previously looked at the layers of security required to protect MSPs from theft of service. In this Tips & Tutorial, we’ll dive deeper into how the Incognito solution offers fraud protection with data sharing.

DHCP and CFM Data Sharing for Fraud Protection

The DHCP service shares what is known about the client with the configuration file management (CFM) service by creating a unique filename for the settings required for the device. This data is then stored in a table on the CFM service for 60 seconds, waiting for the modem request, after which it is deleted.

When the modem contacts the CFM service, it requests its configuration file by the name created by DHCP, and CFM looks up the file settings in its table. The file is then generated on request.
