Cybersecurity Dilemma – Securing Internet of Things (IoT) Networks

There is a growing concern around maintaining a reliable system to play a particular sound track, place an online order by just saying “Hey Siri” or “Hey google”, have your refrigerator detect your food stock, or have your office printer depict its own service automatically.

These tech advancements are driving a growing popularity for “SMART” everything from offices, homes, appliances, buildings & cities. Where all these are connected through the “Internet of Things” (IoT).

IoT is the network of objects, physical in nature which are equipped with sensors, software and other technologies for transmitting data with other devices & systems through the internet. These incorporate immersed systems, wireless sensor networks, controlled & automated systems like smart home devices, as well as smart phones & speakers.

The exploding number & heterogeneity of devices linked to IoT networks is causing an excruciating difficulty to implement cybersecurity, because each device adds to be a potential weak link. 

For more insight, a range of devices include toys, exercise machines, gaming devices and connected cars. And the risk revolving around it could be a possibility of hacking a large number of interlinked cars to shut down cities via deadlock.

Furthermore, smart buildings & cities can also be hacked by getting into automated systems that control ventilation & temperature control systems, fire alarms and other essential foundations. These threats elaborate to the household, hospitality and healthcare industry. 

So if a sector as a whole is exposed to such compromise then where does this lead the individual businesses to? Evidently we have seen a move among enterprises towards adopting a “risk-based” approach to cybersecurity.

This approach to information security lets enterprises pursue strategies specific to their custom operating domain, threat exposure and objectives, this is what we term as enterprise risk management (ERM) strategies widely adopted by several enterprises. But the problem lies where the enterprises have an extremely high tolerance for risk. Since it is commonly acknowledged that there is no such thing as a fully secure system therefore, it is vital to ensure that there’s proper care taken while designing system architecture rather than using this as an excuse. 

But since an enterprise makes their own informed choice they should have an accountability for it as well!? However, there is a lot more to think about than simply holding enterprises responsible. So instead of contemplating on who to blame the thought process should rather be directed in making the IoT networks more secure. 

There are a few recommendations for it like:

  • One is to exert a device foundation to get an informative, latest inventory of the count and variety of devices connected to one’s IoT network. Along with an accountability of their risk profiles, and their trusted conducts. 
  • Another one could be to outline one’s network to contain IoT devices in their own pool of controlled & closely knit security zones, keeping them separate from the other IT assets.
  • Also, the adoption of strong password settings by replacing the default ones of newly connected IoT devices with highly secure ones. Hence, complying to enterprise password policies.
  • Furthermore, on-going patching and updating of codes when feasible could be a risk combination tactic whilst proactively monitoring IoT devices at all times.

Securing IoT networks requires a mix of procuring products that are designed whilst taking a wholesome approach to security. Developers of such products can no longer just be concerned about safeguarding and connecting some particular IT networks. Rather, they must contemplate the consequences about the entire security of the cyber & other tangible systems.
