Posted DateJune 16, 2020
Posted Time 7   min Read

Have you ever switched on the light or your air conditioner with your smartphone? Or have you ever experienced the wonders of a VR box with a motion sensor? What about your fitness band or smartwatch or application security like biometric machines? All these conveniences in our daily lives are the gift of IoT.

IoT or the Internet of things is an intricate system that is interrelated to digital, mechanical, and computing devices via unique identifiers. Simply put, it is the process that takes all the technical things which can be internet-linked, and connect them directly to the internet.

No, your old kettle or laundry machine does not count. But if you purchase the IoT-enabled versions, you can enjoy its benefits like automatic shut-off, smart indicators, etc. In today’s day and age, you will find most of the devices to be IoT-enabled. It can be as simple as a Bluetooth-enabled toy/drone or as complex as fingerprint technology to unlock an app or entering biometric credentials. On a larger scale, you can find the contribution of IoT via offices with sensors or even smart cities.

Statistics on IoT

Statistics on IoT

  • By 2030, 75% of all devices are predicted to be IoT.
  • As per a report presented by Transforma Insights, the assumed IoT revenue market will reach nearly $1.5 trillion by 2030, on a global level.
  • Another report published in Statista also projected the forecast of $1.1 Trillion global spendings by the end of 2023.
  • This will not only cover the Industrial and Commercial electronics segments but has roped in the USA’s smart home control and connectivity segment, whose assumed monetary involvement will cross $30 billion.
  • The healthcare market has also come under the roof of IoT and by 2024 (globally), its revenue would reach around $14 billion.
  • The automotive industry has already invested more than $100 billion and the predictable percentage of IoT-enabled automobiles will be around 70% by 2023.

What is IoT security?

The method of safeguarding IoT networks and devices from the open internet they are connected to is known as IoT security. Focusing on the business settings, Internet of Things devices encompasses:

What is IoT Security

  • Laptops
  • Tablets
  • Smartphones
  • Automation technologies
  • Smart energy grids
  • Industrial machines
  • Biometric machines
  • Internet-enabled Vending machines
  • Smart Sensors

As the stakes with IoT security are higher, the consensus is even lower for security implementation. The developments and innovations related to IoT have become global with a widespread impact. It does not have the same reservations of smart security systems or industrial applications as what businesses had 10 years ago.

  1. The modern-day engineering industry is more focused on creating IoT applications and solutions.
  2. Added to this, the logistics and manufacturing units are blindly reliant on GPS and RFID technology for seamless industrial operations.
  3. If policyholders invest in new financial plans or become loyal members, they are gifted attractive-looking wearables.
  4. Even Google Home and Alexa have become the personal assistant of most of the consumers.

It is amazing how IoT has seeped into the lives of common people, making them feel future-ready, yet often throwing them off guard with myriads of security challenges.

Challenges in IoT Application Security

The market size of IoT application security has grown considerably with time. As per the last report with Europe as the targeted continent, IoT has expanded its revenue root from primarily the consumer segment, estimated to be around €28.5 billion in 2019. When IoT devices are created, they are designed with the requirement of demand fulfillment and not application security purposes.

Challenges in IoT Application Security

And now, the result stands to be several security issues that have become challenges for cybersecurity agents.

1. Brute force

Weak login details and credentials are the two challenging aspects that act as a vulnerability to brute forcing and password hacking.

One of the best examples to explain this challenge is the Mirai botnet. They have utilized highly disruptive DDoS attacks. What they never did when sending the IoT devices to the customers was intimate them to change the given password with a new one.

This action created a hubbub, and currently, the action has become a warning guideline to tackle the dangerous practice.

It is a fact that around 50% of credentials are simply hardcoded directly into Mirai variants’ source code. If you search for it on the internet, you can easily get one. These credentials are generic and can be like:

  • root: root
  • root:1234
  • admin: admin

Moreover, 27% of the attacks were the outcome of such generic groups.

One of the best ways this situation can be tackled is by the usage of Security Information and Event Management. It could execute scripts that can rule in the Web Application Firewall (WAF) and stop the brute force attacks.

2. Ransomware

If you think that IoT ransomware is a serious threat, you are correct. However, you may not be able to guess its intensity. With smart devices connected to the internet, the number of ransomware and malware exploits has increased considerably.

A hacker with ransomware can lock you out of your device or home (if you live in a smart home) and only consents to give access in exchange for a heavy ransom.

3. Data privacy and security

Cloud, web, mobile – aren’t these basics things that you use the most? Well, of course!

All of these things are what connect you to the outside world. Yet, data security and privacy are collaboratively the single biggest issue regarding the internet interconnected world. Large establishment us an array of IoT devices for data:

  • Processing
  • Storing
  • Transmission
  • Harnessing

The devices that are most in use and are sold includes:

  • Smart thermostats
  • HVAC systems
  • Connected Printers
  • Lighting Systems
  • Speakers
  • Smart TVs

When using these devices, you submit your data (apps, entertainment portals, job portals, ticket purchase). The user data is sold or shared amongst companies. In fact, your website is also not safe.

If you have a business website, you should safeguard it with WAF. It is an application security firewall that can protect your web applications by monitoring, filtering, and blocking malicious traffic traveling HTTP/S.

4. Artificial Intelligence

From face recognition in your smartphones to Siri or Alexa, AI and IoT are an inseparable asset from human lives in today’s world. Even for small to huge financial transactions, you are dependent on IoT services.

If you look from the perspective of networking and data collection, a huge amount of data can be difficult to manage. To sift through the huge data amount, detect anomalous traffic and data patterns, and enforce data-specific rules, network security officers and IoT administrators use automation and AI tools. This autonomous decision can cause a misbehaving algorithm and error codes and can affect multiple infrastructure platforms like:

  • Healthcare
  • Transportation
  • Power

This can make the apps weak and prone to theft or cyber-attacks.

5. Remote vehicle access

In addition to hackers taking control of your smart homes, they can also hijack your smart vehicle. Although in progress, Toyota was on the verge of showcasing its brilliant smart, self-automated car in 2020’s Tokyo Motor Show.

These cars are designed with interconnected IoT devices and are under the risk zone of skilled hackers. You can easily envision if an IoT-connected car of yours gets hacked and gets used in lethal crimes, in what position would you stand?

6. No security for minor evasions

The year 2017 saw the emergence of the IoT-based botnet, which was more dangerous than the Mirai botnet – the Reaper. Similar to this IoT-based botnet, it is predicted that more micro-breaches can skip through the existing security net and create chaos.

If such a thing persists, there wouldn’t be the requirement of physical assault or the use of big ammunition. A small information leak or ransomware is enough to create a conundrum.


With the digital world encompassing the real world, we are bound to be a part of the IoT revolution. Security of the device and the app controlling that device is very important and each of the IoT app developers will have to apply the principles of secure coding with even more diligence. However, as an organization, even if you are not in the business of making IoT apps and just have web applications and API; there can be many use cases built around the consumption of your web application where the client interacting with you need not be a human but an IoT device that is consuming, synthesizing, aggregating, and providing relevant use case to its users. A classic example is an eCommerce website that can have orders placed via voice-controlled instruction, along with a schedule or inventory check from a client’s IoT device. Hence, the adoption of application security becomes even more important for you as an organization as the traffic can not just be from humans, but also from IoT-based devices, even if you had not built your business keeping that in mind. Hence, an IoT-based fraud can be amplified across all the systems the IoT devices interact with.

So, independent of your current plans to embrace IoT application development in your organization, if you have a web application, you can assume it will start playing a role in the ecosystem from the client side. With the correct usage of application security measures and software, one can at least try to be ready to scale securely when the IoT adoption and consumption across different use cases become mainstream and all-encompassing. Try inculcating healthy cybersecurity habits like the use of WAF, standards like TLS, and transport encryption. Do not save your confidential details in your system. If you need to, use antiviruses and cybersecurity measures and also continuously keep checking your web application for malware infections and reputation checks on a regular basis too.
