BPI was later enhanced to BPI+ which incorporates digital certificates issued by VeriSign Corporation which are uniquely chained to the individual MAC address of each cable modem.

This was rather weak encryption because it did not authenticate cable modems with unique certificates. BPI was first released in 1999 under DOCSIS 1.1. There are two types of encryption under the BPI umbrella, BPI and BPI+. Why? Because it protects subscriber data from being viewed by malicious users in addition to thwarting potential hackers by using 56-bit or 40-bit DES encryption (56-bit DES is standard). BPI+īPI+ should be considered a MUST do in every DOCSIS network.

So let’s make certain that we have enabled the basic security features within the DOCSIS specifications starting with the Baseline Privacy Plus Interface Specification (BPI+). As we move up to a Layer 3 (router) configuration, we now have something that we can configure as a very rudimentary firewall, but the base configuration of any CMTS does not look like a firewall from a hacker’s point of view. From a hacking standpoint, let’s look at it as a direct connection from the hacker’s computer to your network. Consider your Layer 2 device to be a basic switch. Layer 2 vs Layer 3 – In a previous DOCSIS 3.0 post, I briefly discussed how a CMTS can be configured as either a Layer 2 or a Layer 3 device. Here are is the bare minimum of what you should be doing: CMTS Hacking Safety For now we will just focus on cable modems and the realm of CMTSs and DHCP/TFTP servers. The later would apply for MTAs and set-top boxes. You must implement a layered approach consisting of a number of CMTS, DHCP, TFTP and potentially SNMP and Kerberos related methods. What this indicates is that any reliance on a single point or method of hack-proofing your network WILL NOT WORK. But often individual techniques are “hacked” (such as in the TFTP-Enforce bypass method found on hacker sites).

Vendors have put into place very effective, CMTS specific techniques, such as Cisco’s TFTP-Enforce which prohibits a cable modem from registering and coming on-line if there is no matching TFTP traffic through the CMTS preceding the registration attempt. I will protect the vendor’s identities because I believe that the CMTS is the first line of defense. Not surprisingly, one vendor’s CMTS was able to ward off the hacker’s while another vendor’s CMTS was unable to prevent the uncapping and subsequent theft of service. Recently a reader contacted me and said that theft of service, especially uncapping cable modems via hacking, was still impacting his network. Depending upon what they are doing, this could have significant impacts on other services being offered to subscribers.

Finally, with DOCSIS 3.0, uncapping modems could result in hackers accessing download speeds in excess of 150 Mbps+.

Further there are hackers who do not pay for service at all and connect cloned modems to get free service. If I’m already getting 12 Mbps, what is the difference if I up it to 20 Mbps? Hey, who of us can honestly say we have never broken the speed limit? Have you never driven 50 MPH in a 40 MPH speed zone? Most people can self-justify a lot of small “law bending infractions”, but what hacker’s may not realize are the impacts they have on other users in the network. Your paying for some level of DOCSIS cable modem service and you just want to get a little more speed our of your modem. Look at this from the subscriber’s point of view, you have a coax cable coming into your house. DOCSIS security holes are a serious problem, even if you are a major MSO (Multiple System Operator).
