The introduction of the IoT has become one of the greatest and most significant inventions ever made. The concept of connected devices has not only simplified our daily lives, but has redefined the term “convenience” in the future.

From intelligent power grids to industrial machines, smartwatches, smartphones, smart door locks, smart bikes, fitness trackers, smart security systems, smart refrigerators, medical sensors in almost every device today have shifted to IoT. The concept of creating a network of physical things or objects embedded with software, sensors and technology to connect and exchange data with other systems and devices on the Internet has become the idea of ​​the century.

However, to secure this virtual network of physical objects or items, we consider IoT security because it helps protect connected networks and IoT devices and ensures that any connected objects, or smart refrigerators, manufacturers or key worlds wise, be free hacking. Simply put, gaining control of IoT devices and stealing user digital data becomes a challenge for hackers when IoT security is worked out accurately.

Let’s dig quickly into the details of how IoT security can be increased in order to create a more secure and secure approach to the connected future.

A risk-based approach

A risk-based approach is a mentality that allows you to improve the certainty of achieving results by using strategies or methods that take into account threats and opportunities. This approach can be applied during operations during process or product design or in product improvement phases.

Also, a risk-based approach allows you to seize opportunities, prevent losses, and improve all operations across the organization. Therefore, it would not be wrong to say that considering a risk-based approach should become an essential element of quality management systems, performance excellence processes, including ISO 9001: 2015. The approach can be help you understand the risk matrix of your devices so that you can apply the appropriate security controls to an IoT system.

Update Firmware & Software

Firmware and software updates are an essential process if you plan to improve IoT security, as software updates offer many benefits. For example, these can help repair security vulnerabilities that may occur due to computer malfunctions.

Basically, the update process is about reviews and allows you to update / add features to your IoT devices and eliminate obsolete ones. Moreover, updates always help your operating system to run in the latest version. If you do not work on updates or upgrade your IoT device, it can be difficult for you to get the most out of your business.

However, working on the update process may require you to request some IoT security testing services to help mitigate security issues within the IoT ecosystem. However, exposure to some IoT testing techniques such as threat modeling, firmware analysis, protocol testing, incident response testing, etc., allows you to offer more consistent solutions.

IoT Device Security Features

Whether you have a small connected device or a complicated network of IoT devices, always try to meet specific security criteria with IoT security testing. There are seven key IoT features you can check out below. Then, based on your understanding, you can perform tests to ensure that all features of the device work properly, are error free, and are safe from any risk of hacking.

Connectivity: From hardware, sensors, electronics to systems, everything on IoT devices is connected, so you need to check if connected devices and control systems can make a connection between different levels or not.

Things: Anything that can be linked or tagged is created to be linked. Your IoT device may contain various sensors or sensory materials that need to be attached to objects and devices properly.

Data: Data is the glue of the IoT, and is the initial step towards action and intelligence.

Communication: IoT devices are connected to one or more systems, so of course, their data can communicate during exchange or sharing through devices. Furthermore, communication can occur over short distances or long distances. For example, Wi-Fi is easy to connect to software for audio / video calling. Therefore, for IoT, data traveled from one country to another needs to be analyzed and tested.

Intelligence: IoT devices have sensing capabilities that we might call Intelligence, and that intelligence can be gathered by Artificial Intelligence and Big Data Analysis.

Action: It can be a consequence of intelligence and action can be based on debate or manual interpretation. For example, in factory smart decisions, automation helps make an important decision.

Ecosystem: It could be the Internet of Things site that relates to the technologies, other communities, photography, or purposes to which the IoT fits.

These seven key features of IoT should be considered when evaluating the security of IoT devices. Moreover, working on these features allows you to test the security capabilities to ensure that your IoT product is stable to use. Moreover, controlling for these factors helps you establish several distinct lines of accountability and responsibility for the entire IoT ecosystem.

Automate security whenever possible

Due to the growing demand for connected devices and endpoints, the deployment of IoT raises the need for increased automation for threat identification, data monitoring and other aspects of security levels. But still, the main purpose of using automation within the development phase should be security control. Therefore, every feature of IoT devices should be checked to help users get the maximum level of protection. Moreover, as different IoT solutions come with different communication networks and levels, so you should not hesitate to go after an IoT device, including applications, to meet critical security requirements.

Set Encryption to Default

Sometimes, it can be difficult for companies to store their data in an encrypted format. However, if you want to increase IoT security, you need to consider data encryption to ensure that data will never be transferred in plain text, but sent securely. If it is not possible for you to encrypt the data, you can choose an alternative option like VPN to protect your confidential data.

IoT is more than a technology that most enterprises use to take advantage of business, such as improving staff productivity and reducing human labor. Instead, it is a futuristic approach to ensuring better usability of resources and assets, efficiency of operations management, reduction of operations costs, improved customer service, improved occupational safety, targeted business development and marketing, and much more.

However, if you have futuristic goals related to the use of IoT that you should include in your operations as well as the products you offer, you should first focus on improving the security of your IoT devices by adhering to all of the above factors as these have potential to create or ruin your business.
