Securing Networks In the Internet of Things Era 106

Posted by timothy from the glad-that-someone-finally-invented-things dept.
An anonymous reader writes "Gartner reckons that the number of connected devices will hit 26 billion by 2020, almost 30 times the number of devices connected to the IoT in 2009. This estimate doesn't even include connected PCs, tablets and smartphones. The IoT will represent the biggest change to our relationship with the Internet since its inception. Many IoT devices themselves suffer from security limitations as a result of their minimal computing capabilities. For instance, the majority don't support sufficiently robust mechanisms for authentication, leaving network admins with only weak alternatives or sometimes no alternatives at all. As a result, it can be difficult for organizations to provide secure network access for certain IoT devices."

    Most of the management types I've met have just enough functioning brain cells to kiss ass and repeat whatever mantra they learned in MBA school or during the most recent management retreat.

    Target was breached because HVAC maintenance had access to the same network as the POS terminals, which is inexcusable stupidity. Unfortunately, this is exactly what will happen with the IoT devices. Putting them on an entirely separate network (own APs for wireless, blinkenlights, ...) will cost something, and, since the CIOs don't spend hard time in a closed prison for exposing their systems, or the personal data of employees or customers, they simply will not authorize the expenditure.

        Sorry, but "Internet of Things", the term at least, has become a buzzword. As you correctly identified, it's bullshit bingo material considering that pretty much anything connected to the internet almost invariably has to be a thing (apologies to all the cyborgs out there). The "buzzwordism" (I really hope that doesn't become a buzzword now...) lies in the term meaning something along the line of "appliances connected to the internet that were not supposed to be connected when they were originally created". Routers, switches, hubs, bridges... they are by definition supposed to be connected to some sort of network. They have no use outside of one. Computers, gaming consoles and maybe even TVs kinda "belong" on a network, because even though they have a use without, it kinda makes sense to connect them.

        It's different for what the appliance industry termed "white goods". Washing machines, dryers, fridges, stoves... they came into existence long, long before anything remotely resembling a computer or internet, and people don't immediately consider them something they would possibly connect to a network. Those are the "things" the "internet of things" talks about.

        And this is basically also the reason why "internet of things" belongs to the buzzwords. Or, maybe rather, buzzterms. It's a made up term that qualifies a certain group of items that makes no sense whatsoever outside the world of marketing.
