THE INTERNET OF THINGS, or IoT, is often misconstrued to only mean the intercon- nectedness of appliances, computers, microprocessors and machines, all of which have IP addresses or some form of digital identification. While IoT includes these capabilities, it s far more pervasive. More precisely, the IoT is the interconnectedness of devices coupled with auto- mated and centralized data collection and analysis capa- bilities from those devices. Interconnected IoT devices, and their ability to collect and broadcast data (or have data extracted from them), can bring extreme convenience and a measure safety that was unheard of even 10 years ago. When linked to big data analysis, enterprise workflow optimization can be done in real time, offering a new level of operational improvement. However, with the conve- nience and improved effec- tiveness of the IoT comes the potential for extreme vulner- ability if IoT devices are not designed with security from the outset. This vulnerability can easily rise to the level of a national security risk. Supervisory control and data acquisition (SCADA) systems control elements of the critical infrastructure, including power systems, waterways, traffic signals and communication systems themselves. The machines that comprise the critical in- frastructure no longer stand alone, isolated from one another. They are connected in ways where they can serve as portals to related infra- structure. That s extremely conve- nient for load-balancing work, adjusting to just-in- time inventory demands or detecting where lean mea- sures need to be applied. But this network is vulnerable to attacks that could even shut off the power grid, paralyzing first responders in advance of a terrorist attack. So, in the jargon of the industry, enough fear, un- certainty and doubt (FUD). What can you do to protect your agency, its devices and the critical infrastructure that will increasingly take advantage of the IoT? Do the basics first: 1. Ensure that devices receiving updates over the web are doing so over secure systems. Ensure that connectivity is secure and use devices that provide for two- factor authentication, e.g. a physical device and a PIN as- sociated with those devices. 2. Secure the location of the data being reported by IoT- linked devices. Ask the IoT service provider how the data collected is being protected, both virtually and physically. 3. Encrypt the system. Criti- cal infrastructure systems must use encryption if they are going to ride the web. But even this security protec- tion is not enough to protect against attacks by insiders. Two-person controls, where administrative control of passwords and operating systems is shared, will help prevent insider threats. 4. Ensure supply chain se- curity. Critical infrastructure and defense systems must have procedures to certify manufacturers supply chain processes to prevent the in- troduction of malicious code. 5. Support IoT security. As technology purchasers, we must vote with our dollars and support those manufac- turers that invest in security up front for IoT. We must sup- port regulation that requires that IoT devices meet security standards, just as we require standards for our electrical devices. 6. Use out of band (OOB) systems -- closed systems (intranets) that are not open to the public. The Defense Department uses IoT linked devices, but they are mainly out of reach from hackers because they are OOB. While less vulnerable to being hacked, these OOB systems are subject to insider attacks. 7. Support standardization. The Open Web Application Security Project is an online community dedicated to web application security, and it is standardizing such items as secure web interfaces, au- thentication, secure network services, transport encryp- tion, secure cloud and mobile interfaces, security configura- tion control, secure software/ firmware and proper physical security, all of which must play into a comprehensive and integrated approach to securing the IoT. 8. Stay informed. Other key sources for the most recent information on managing the security of such devices are the National Institute of Standards and Technology and federal guidance such as Federal Information Process- ing Standards (FIPS). These sources address critical steps that are needed to secure and protect information and criti- cal systems. The IoT trend is only going to grow. We need to ensure that it grows with embedded security capabilities to pro- tect our data and our critical systems. • --- Richard Breakiron is ViON s senior director of Cyber Solutions.
