Discuss this topic on Collabratec:

In part one of this two-part article, we discussed fundamental issues with the Internet of Things (IoT). In this article, we present some of the technical issues with the IoT that could prove as the downfall of the IoT.

It is said the attack on Dyn was the cyber-attack that almost broke the internet into numerous islands on 21 October 2016, and is the largest one observed yet [1]. Dyn is an organization that has both capacity and capability to process high volumes of data; it was an asynchronous yet persistent attack that flooded the Domain Name Servers at Dyn Inc.

There is a wide consensus on the fact that the volume of attack is going to grow in the future. To date, the large scale distributed denial of service (DDoS) attacks have been unilateral requests. These attacks rather gave up their sources, mostly reflectors or rogue edge routers, rather easily and were contained by the security engineers through isolation techniques, i.e., sinkholes [10] etc. Had they been multilateral requests, they would have been impossible to contain. Keeping the root servers down for a couple of hours to shed the load can be enough to change the border-less, free, and ubiquitous internet forever.

On one hand, the overwhelming popularity and high market penetration rates of the devices that are internet enabled break open new frontiers for the IT industry. It happens so because the internet enabled device manufacturers have software implementations confined to lower OSI layers stacks, which bring the cost down. The lack of standards in manufacturing quality, software quality, and quality assurance also play a major role in low device quality. On the other hand, since the IoT initiative is relatively new, there is a lack of protocols on how to amalgamate 50 billion more thin clients in IoT enabled devices into the already existing size of the internet [2].

In our research the ownership, functional restrictions, physical security, IoT-facilitated cyber-crimes, infrastructure, addressing, and usage are among the most troubled areas in IoT roll-outs and need immediate consideration. We classify these issues in the order of OSI layers in the following passages:

  • The fundamental principle of the IoT initiative is to enable devices from different manufacturers to be able to communicate with each other without a gateway for protocol translation. A digital device is not made to last forever. It needs to be retired, i.e., replaced, discarded, recycled, etc., after its life span is over. Throughout this life span of a digital device, it must be maintained too. The maintenance plan cannot be developed in the absence of a deployment and manufacturing plan. The manufacturing and deployment plans must follow standards so that different vendors may find harmony in cross deployments. Since the IoT devices are typically not deployed within the four walls of an organization, an attacker can easily eavesdrop on the IoT traffic. The IoT devices generally have resource constraints. Therefore, manufacturers cannot take data encryption on board because the resource demands of an encryption scheme can be detrimental to their profit margins. We propose [6] that the information flowing from the IoT devices be so atomic in nature that to make a substantial use out of eavesdropping, the attackers need to eavesdrop on the considerably large population of the IoT devices of various kinds. An example of this argument can be temperature sensors. An attacker may eavesdrop on the temperature reading of one point, but unless he eavesdrops on all the temperature sensors of the power plant, he might not know where the boiler room might be. One can argue about the radio interference among IoT devices and advocate the use of adaptive radios; in our opinion, with the ubiquitous deployment considerations, restrictions on the scope of IoT devices and their coverage range can complicate things beyond repair in no time.
  • One of the biggest shortcomings in IoT device deployment is poor implementation of auto configuration of the devices. Since IoT inherits a bulk of its security problems from the Transmission Control Protocol/Internet Protocol suit, the issues like Address Resolution Protocol spoofing, Contents Address Table-based attacks, Dynamic Host Configuration Protocol starvation, Hidden Node Attacks, Watering hole attacks, De-auth attacks, and the list goes on, are among common threats to the IoT. Because the attack space is so wide, it is very tempting to beef up and customize the Intrusion Detection systems. Customization, in principle, is discouraged in a pervasive deployment. We propose, as discussed in the previous section, that the IoT clusters should be atomic and small. The larger the cluster size, the more vulnerable it would be to attacks. The real value of IoT applications is in services that run devoid of underlying networking details. Hence, the value should be given to the quality of data. We are further researching a solution to overcome the data link layer security issues in the IoT. We also believe that there is a serious lack in competition in management protocols at lower layers, specifically at the data link layer in IoT. The classic protocols for flow control, error control, timeout protocols, etc. were designed for deterministic traffic flows. However, IoT devices broadcast in opportunistic fashion. In conclusion, these are exciting times for the IoT industry, but if by adopting TCP/IP as a lone ranger for the link layer problems, we can already see that it is not working out well for the IoT industry.
  • We take the position of semantic quality in the Internet Protocol (IP) related issues in IoT enabled devices. An IP is an identity given to a device through which it can use some services provided by the internet. Our stance is how can a device with full OSI stack, in full compliance to standardization and security controls, be at the same service level as an IoT device with less than desired implementation and design? The process of IP recycling and converting all their product line in an “IP enabled product” by the manufacturers further complicates the issues. So, it is not about the new IoT devices. The problem has escalated to the older IP addresses too. The IEEE Standards Association (IEEE SA) has IEEE P2413, and many alike are working on developing specifications for a shared Machine-to-Machine (M2M) network layer to connect IoT devices globally. Maybe this is the solution we have all been waiting for. As proposed in [4], the IoT enabled devices must be deployed in domains. However, we propose that these domains should be soft domains and must be created on the fly and on a lease. This loosely coupled environment ensures cross domain functionality in a truly ubiquitous environment [5].
  • The transport layer inherits the shortcomings of the TCP and User Datagram Protocol. At this stage, the industry is looking toward academia for more alternatives to the TCP and the UDP. The machine-to-machine layer that sits on top of the transport layer in IoT devices is still at its developmental stage. However, the smart applications layer running on top of it all has had a good run. A few experimental setups were built, but due to lack of business models and to some extent non-availability of mature technologies, the market trust in starting a new technology was minimal [7].

The situation has changed. New applications are being built [8], and we all are very excited about the IoT and the traction it brings for the IT market. There are still issues like IoT device ownership, refined business model, revenue sharing, device life cycle management, trust and security of personal data, privacy and reliable information delivery that we are working on and soon we shall overcome them all [9]. In this article, we enumerated some burning issues with the IoT technology that needs addressing immediately. Until we address the issues mentioned above, the IoT will continue to be the Internet of Threats.
