IOT in Cyber Security - All You Need to Know

IoT solutions are being implemented by businesses in many industries to increase visibility and boost productivity. Attackers constantly look for fresh ways to break into systems, steal data, and access systems. Any IoT system might become a potential target for hackers, from medical gadgets to navigation systems on connected cars.  

There are currently about 24 billion operational technology (OT) and internet of things (IoT) devices in use, and by 2030, there will likely be billions more. It makes your life more enjoyable and convenient as an individual. An individual can communicate with one another and receive information instantly. Businesses adopt smart IoT devices because they enable ongoing customer communication and data collection.  

The Internet of Things (IoT) gives organisations new opportunities to add value, but the constant connectivity and data sharing also opens up new possibilities for information security breaches. This blog will help you understand IoT in Cyber Security, some common threats, how to secure an IoT ecosystem, and many more.

What is IoT in Cyber Security? 

The Internet of Things (IoT) is a network of physical things that can be accessed through the Internet, identify themselves to other devices, and interact with internal and environmental circumstances using embedded technology. The Internet of Things (IoT) is an environment in which a thing that can represent itself grows in size by connecting to surrounding objects and the vast amount of data flowing around it.  

IoT Cyber Security is a technology field devoted to safeguarding networks and connected devices in the Internet of things (IoT). It includes connecting mechanical and digital equipment, objects, animals, and/or humans to the Internet. Each "object" is given a unique identification number, and the ability to transfer data over a network independently. Allowing multiple devices to connect to the Internet exposes them to many serious threats.  

The Internet of Things (IoT) links different items and machines together so they can talk with other similarly connected devices or gadgets. With the help of the internet, users can also purchase a wide range of products. Expanding networking capabilities can make you more effective, save time and money, and access your digital lives whenever you need them.   

Cyber Security professionals refer to this as extending the attack surface that hackers can exploit. Security specialists are aware of this and try to mitigate the security threats that occur from it by implementing robust cyber security essentials measures.

What are the common threats in IoT? 

IoT threats have a meagre risk rate, but a few high-impact threats can cause severe damage. Threats to IoT security can take many different shapes, ranging from simple password leaks to more complex cyber security attacks that take advantage of flaws in IoT devices. Let's take a look at a few threats mentioned below:  

1) Access to private information- One significant risk is the potential for hackers to access personal data kept on IoT devices. This may contain confidential information about an individual (such as names, addresses, and passwords), financial data (like bank account and credit card numbers), or even confidential military data (such as troop movements and strategic plans).  

2) Installation of fake devices- Another high-impact threat is the installation of counterfeit devices in computer networks or government institutions. These devices are used to break into other systems and steal confidential data.  

3) Launching cyber-attacks- Hackers may use IoT devices as a launchpad for attacks on other systems. This can involve gaining access to personal data, stealing cash or information, or attacking essential infrastructure systems.  

4) In-vehicle security breaches- According to a recent survey, more than 50% of US drivers are subject to hacking assaults, many of which occur without the victim's knowledge.  

5) IoT device tampering: One of the most popular ways to take advantage of IoT devices is to tamper with their software, which can lead to data loss or corruption.  

6) Data theft- is another frequent IoT security risk. This is frequently used to gain access to financial or personal data.  

7) Unprotected internet connections- IoT devices may be prone to attacks, including hacker attacks, due to a lack of security regulations.  

8) IoT open-source software flaws- Many IoT devices use open-source software, which is subject to assaults.

How to Secure the IoT Ecosystem? 

For several reasons, securing IoT devices takes a lot of work. Security is frequently given a lower priority than time-to-market metrics since manufacturers and innovators are under pressure to release innovative goods. Many businesses are also unaware of the security risks posed by IoT and are frequently more interested in the cost savings and convenience that IoT may provide.  

By 2020, nearly 25% of cyber-attacks against businesses, according to Gartner, will incorporate IoT. Industrial IoT (IIoT) systems face incredibly high stakes. Connected IoT sensors and devices can considerably raise operational hazards across various infrastructures, from national power generation and distribution systems to global manufacturing operations.  

Securing the actual devices is one solution to the issue. For instance, some equipment might be used continuously unattended, and even if they are not constantly watched, they still need to be secured. Strengthening these endpoints with tamper-proof security measures can prevent intruders from gaining control or accessing sensitive information.  

Along with individual IoT devices, organisations must also ensure that their IoT networks are secure. Strong user authentication and access control measures can ensure that only authorised users can use the IoT framework.

Future of IoT Cyber Security 

Here are a few techniques IT professionals may use to strengthen their IoT device security methods:  

1) Improve device monitoring: Information sharing and using intrusion detection systems (IDS) and security information and event management (SIEM) systems can be helpful. Using cybersecurity threat intelligence (CTI), setting security controls for IoT devices becomes easy.  

2) Increase security features: Including functionality that encrypts all transferred and stored data can be beneficial. Additionally, employees can learn how to segment and divide IoT traffic more effectively so that it can be readily handled and controlled. They can respond to security breaches more effectively using this technique.  

3) Follow IoT standards: The National Institute of Standards and Technology (NIST) has issued numerous cybersecurity standards, including recommendations for IoT device manufacturers. It has also published a helpful page outlining its Cybersecurity for IoT Program. 

Conclusion 

While organisations might not be able to completely prevent IoT attacks from occurring, they can implement preventive measures that can lessen threats to essential systems and data. Cyber Security for the internet of things (IoT) is the top priority for all individuals and organisations. Hope this blog gives you fruitful insights to clearly understand the need to optimise your work processes with IoT for a safer tomorrow.
