I hope you’re wrong (or at least inaccurate) about the IoT concept. Recent history suggests that we lack the ability to secure anything from attackers with access to the same network, given enough time and motivation on the part of the attackers. An Internet of Things will rapidly turn into an Internet of Subverted and Compromised Things.

Of course, I’m taking “Internet” to mean “Internet”, as in the big public global network we’re all using here, and not just “network”. Maybe this is just a case of buzzwords that shouldn’t be taken literally. There’s nothing wrong with networks of things, so long those networks are well insulated from the Internet at large.

Perhaps the good news is that the (Australian) NBN will make non-Internet high-speed wide area networking generally available. The NBN only provides a layer two service: it doesn’t have to be the Internet if you don’t want it to be. When we think of VPNs, currently, we think of the “private” part being enforced by cryptographic means while being transported over the public Internet. The NBN can support VPNs directly, without the need to be layered on the Internet. You can decide for yourself whether you still want the cryptography.

This kind of thing has been possible before, of course, but not with the speed or ubiquity that the NBN will offer. For example, if you want to work from home and be connected to the corporate network, you currently use a VPN over your domestic broadband Internet connection, because no private virtual circuit comes close to competing on cost. With the NBN, private virtual circuits are essentially the basic product: Internet service is just where you have a PVC to an ISP. Corporations can thus extend their networks into the homes of employees without touching the Internet at all. If the organisation already uses VoIP infrastructure, then the employee is also trivially attached to the corporate telephone network as well.

An Internet of Things sounds like trouble waiting to happen. I’m more interested in the fact that the NBN will be a Thing of Networks, of which the Internet will be but one of many.

Hi Brett, I agree with your assumption that the current Internet is not secure I clearly differentiate from the current networks as the title of the blog indicates I am talking about the combined features of fibre-based NBNs — robustness, ubiquitousness, affordability, security, privacy, low latency, etc. In fact, NBNs will be gigantic computer networks. With that in place IoT, cloud computing, etc can be delivered in a secure way. Not that there won’t be problems or criminals breaking into it. After 500 years of banking also that system is not bulletproof but we accept the level of risk within certain boundaries, we do need to establish these boundaries also for IoT and a FttH network is one of the key elements that can facilitate this.
