Recently we all have found ourselves talking about the risk and impact of poorly secured IoT technology and who is responsible. Fact is there is enough blame to go around for everyone, but let's not go there. Let us start focusing on solutions that can help secure IoT technology.

Usability has been an issue that has plagued us since the beginning of time. As an example, just going back to my youth and seeing my parents VCR flashing 12:00 all the time. We laugh at that, because it showed us their lack of understanding around how technology works, and of course it was not a real risk to anything other then knowing what time it is and not being able to preset and record shows. Today, the inability to understand or configure our technology is much more of a risk than the flashing 12:00 on our parents' VCR. Such misconfigured IoT devices can lead to various compromises of our information or allow our technology to be used in attacks against others. Currently we often find IoT devices working out of the box with every feature enabled and also using default passwords, and of course this approach has come back to haunt us in a number of cases.

I am sure we all agree that the days of every feature being enabled and default passwords out the box needs to change. Although, don't get me wrong, I still think IoT technology should be easy to deploy -- but with security built in. So what should that look like? Let me break it down in a few basic items that I think are paramount to getting to that point.


No default passwords enabled. It is easy enough during deployment of a product to have the user set a strong password. In cases where each device has a unique default password, those should also be changed and if not, the user should be warned that the password has not been changed and then forced to acknowledge that with a multi-step process each time they use the products. Check out this new tool built by the Metasploit team at Rapid7 called IoTSeeker which scans your network for IoT devices and let's you know if the default password is being used.


Initial installation should only enable needed services for functionality. These extra services should only be configurable after initial setup. A check box list for features during initial setup is not the way to go. It will only lead to user selecting every one of them just to make sure the installation works. I know, because in a past life I have watched coworkers do exact thing during product installations.


Good documentation is critical for walking a user through the secure setup. This documentation, beside covering standard setups and which may include an intuitive web wizard, should include guidance on enabling expanded features or specific services that have security implications the user should be made aware of during setup. With the ever-expanding list of capabilities and features associated with IoT its imperative that the end user is given guidance "Good Documentation" to help with selecting and implementing the most secure methods during setup of their device.


Automated firmware patching should be the default. If not, the user should be prompted every time they use the product when firmware updates are available. Patching allows us to fix security issues within the products moving forward. We are always going to have problems and having the ability to correct them on the fly is important.


This simple list points out items that create a solid foundation from where we can continue building on IoT security and at the same time maintain a solid resemblance of usability; however, I expect it will still take a while before we see these items commonplace within all new IoT -- and I am looking forward to that day.
