Security of communications in IoT – Security Boulevard

Devices and networks connected to the Internet of Things are protected by IoT (IoT) security. Computing devices, mechanical and digital equipment, items, animals, and/or humans connect to the Internet through IoT. There are unique identifiers for each “thing,” as well as the ability to automatically transfer data over a network. As long as devices are not adequately protected, they are vulnerable to a variety of significant vulnerabilities. As a result of many high-profile incidents, IoT security has become increasingly important. For networks with connected IoT devices, this is important. Technology, approaches, protocols, and activities can be used to minimize the growing IoT vulnerabilities of modern organizations.

What is IoT security?


The protection techniques employed to secure Internet-connected or network-based devices are known as IoT security. The phrase Internet of Things (IoT) is quite a broad one, and as technology continues to advance, the word has gotten bigger. Almost all electronic items can communicate with the Internet or other devices in some way.

IoT security refers to the approaches, strategies, and technologies that are used to prevent these devices from being hacked. Ironically, the inherent connection to IoT devices exposes them to hackers.

Due to the wide scope of IoT, IoT security is much more extensive. As a result, a wide range of techniques now fall under the scope of IoT security. These are just some of the strategies IT executives can employ to address the growing danger of cybercrime and cyberterrorism rooted in insecure IoT devices.

Internet of Things (IoT) security issues

The chances of a threat actor intercepting a device increase as there are more methods for devices to connect to each other. Cybercriminals can intercept protocols such as HTTP (Hyper Text Transfer Protocol) Y API, what IoT devices they use to communicate. The scope of the Internet of Things (IoT) does not cover only devices connected to the Internet. In addition to Bluetooth-enabled devices, IoT security is required for all IoT devices. IoT-related data breaches have recently increased as a result of such oversights. IoT security issues continue to pose a danger to the financial security of individuals and businesses.

Remote exposure:

Due to their Internet-based connection, IoT devices offer a much larger attack surface than traditional technologies. Although this level of accessibility is very beneficial, hackers will try to use it to remotely interact with your computer. Because of this, hacking campaigns like phishing are especially effective at stealing personal information. To safeguard assets, IoT security, like cloud security, must control a large number of access points.

Lack of Industry Foresight:

Certain sectors and their products have also undergone digital transformations as a result of the digital transformations of companies. To increase productivity and efficiency, industries such as transportation and healthcare have lately expanded their range of IoT devices. It has also led to a greater reliance on technology than ever before.

However, reliance on technology can magnify the effects of a successful data breach. These companies are relying more and more on IoT devices, this is very alarming. In addition, it is expensive and requires efforts for many health care and automotive companies to protect their devices. Consequently, many companies and manufacturers have been exposed to increasing cybersecurity risks due to this industry-wide shortsightedness.

Resource constraints:

It’s not just a matter of lack of foresight when it comes to IoT security, as newly digitized industries have discovered. IoT security is further hampered by the resource limitations of many of these devices. Some IoT devices don’t have the processing power to run complex firewalls or antivirus software, so they can’t be equipped with these features. Only a few devices are capable of connecting with other devices. Bluetooth-enabled IoT devices, for example, have recently been the target of a wave of data leaks. Unfortunately, the automobile industry has been the one that has suffered the most from this attack.

How to protect IoT systems and devices

Design your system with IoT security approaches.

A better research and development approach from the beginning of any consumer, corporate, or industrial IoT device can solve most of the prominent security issues. Security should be enabled by default and the latest operating systems and security hardware should be used.
It’s important for IoT developers to be aware of cybersecurity risks at every stage, not just during the design process. Key rings can be protected by placing them in a metal box or away from windows and hallways, for example.

PKI and digital certificates

The use of Public Key Infrastructure (PKI) is strongly recommended to secure client-server communications between many networked devices. PKI facilitates the encryption and decryption of private communications and interactions through digital certificates using an asymmetric two-key cryptosystem. The clear texts of customers entering the website can be protected privately. Without PKI, electronic commerce would be impossible to carry out.

network security

Threat actors can remotely manipulate IoT devices over networks. Because networks can contain both digital and physical components such as access points, IoT security should support both. In some cases, antimalware, firewalls, and intrusion detection systems/intrusion prevention systems may be used to prevent threats such as unwanted Internet Protocol (IP) addresses.

API security

Most of the complex websites are based on APIs. These systems allow travel agencies to collect flight information from multiple airlines in a single database, for example. As a result, the security of the API must be protected and only authorized applications and people can access and modify the data. Those things help us ensure the accuracy of data being transferred from IoT devices to systems. Unfortunately, hackers can breach these communication channels. For example, the T-data Mobile leak in 2018 is a clear illustration of what can happen. The mobile giant leaked personal data (zip codes, phone numbers,…) of more than 2 million users due to a “leaky API”.


IoT security threats affect which industries the most?

Starting from a smart House to a factory to a connected car, IoT security breaches can happen anywhere and in any industry. As a result, the degree of impact varies widely depending on the system, the data collected, and/or the information included.

Life-threatening situations include a cyber attack that disables the brakes of a connected car or a hack that allows connected health equipment, such as an insulin pump, to overdose a patient. IoT-monitored refrigeration systems can be attacked, destroying drugs if temperatures change. Attacks are also likely to have devastating consequences on key infrastructure such as an oil well, the power grid, or the water supply system.

The threat of further attacks, on the other hand, should not be overlooked. A cyber attack on smart door locks, for example, can allow a thief to break into a home. A hacker can also use a linked device, like the HVAC system in the Target example, to collect personally identifiable information, causing chaos for those affected.

final thought

All in all, companies applying IoT technologies must examine and manage the security threats posed by the connectivity of IoT hardware and software to reap the benefits of IoT. They need to take steps to protect their devices, their networks, and their data as soon as possible.
