What are the Challenges of IoT Security?

IoT has many of the same security challenges that other systems have. There are, however, some challenges that are unique to IoT.

  1. Embedded Passwords. Embedding passwords in IoT devices make it easy for remote support technicians to access devices for troubleshooting and simplifies the installation of multiple devices. Of course, it also simplifies access to devices for malicious purposes.
  2. Lack of device authentication. Allowing IoT devices access to the network without authenticating opens the network to unknown and unauthorized devices. Rogue devices can serve as an entry point for attacks or even as a source of attacks.
  3. Patching and upgrading. Some IoT devices do not provide a simple (or any) means to patch or upgrade software. This results in many IoT devices with vulnerabilities continuing to be in use.
  4. Physical hardening. Physical access to IoT devices can introduce risk if those devices are not hardened against physical attack. Such an attack may not be intended to damage the device, but rather to extract information. Simply removing a microSD memory card to read its contents can give an attacker private data, as well as information such as embedded passwords that may allow access to other devices.
  5. Outdated components. When vulnerabilities are discovered in hardware or software components of IoT devices, it can be difficult and expensive for manufacturers or users to update or replace them. As with patches, this results in many IoT devices with vulnerabilities continuing to be used.
  6. Device monitoring and management. IoT devices do not always have a unique identifier that facilitates asset tracking, monitoring, and management. IT personnel do not necessarily consider IoT devices among the hosts that they monitor and manage. Asset tracking systems sometimes neglect to include IoT devices, so they sit on the network without being managed or monitored.

Most of these issues can be attributed to security being an afterthought (if a thought at all) in the design and manufacturing of IoT devices. Even those IoT developers who consider security in the design process struggle with implementation. Most IoT devices are limited by minimal processing power, memory, and data transfer speeds. This is a necessary evil in order to keep the size and cost of the devices small. Accordingly, security controls must be implemented to compensate for these inherent weaknesses.

The first step to implementing security controls is to determine where those controls are needed. This is another challenge for protecting IoT devices. Since IoT devices are often not recognized as network devices, they get overlooked when inventorying or mapping the network. If you do not know it is there, you cannot protect it.

Fortunately, IoT device manufacturers are beginning to address these issues, but organizations that are planning or currently using IoT cannot sit back and wait for that to happen. There are measures that organizations can take right now to protect their IoT devices and networks from attacks.
