We are confident that we have what it takes to help you get your platform from the idea throughout design and development phases, all the way to successful deployment in a production environment!
Why is IoT Cybersecurity Important?
There has been a notable increase in the frequency of attacks on IoT networks. Data reports there were about 22 million attacks in 2022 alone. These disheartening statistics incentivize industries to recognize the dangers and implement risk management strategies to keep their operations safe.
As IoT technologies evolve, so do the methods to attack them. Attackers are now developing sophisticated intrusion methods, P2P control and management, and worm self-propagation capabilities to harm the system. Add to this list weak device security, and attackers are just a step away from hacking the system.
The risks are substantial for industrial IoT ecosystems. Car manufacturers, energy enterprises and shipping firms use a form of IoT — operational technology (OT). They are managed by an industrial control system with devices and network capabilities that let robots, wind turbines and container ships operate efficiently. These systems can also be the subject of attacks. Integrating connected sensors and IoT instruments brings about a rise in functional risks, from nationwide power supply networks to international manufacturing operations.
The business landscape can also become a victim of attacks. Companies that create devices often don’t pay enough attention to security practices. However, it’s a big mistake which might be costly. The go-to choice is to enforce a comprehensive strategy requiring the collaboration of all parties because everyone has a stake in guaranteeing the devices’ protection.
One of the options is to enforce SecDevOps or DevSecOps. You can use the Global Cloud Team solution. A team of cybersecurity experts ensures efficient deployment using agile methodologies. It reduces overall production time and related risks. It means efficient day-to-day operations that are scalable in the long run.
Examples of IoT Cybersecurity Tools
Today, you can find many programs on the market that’ll help you guarantee the safeguarding of the devices. Let’s look at the main stars in the field who won the favor of cybersecurity specialists.
The framework is used to create M2M applications that help you scan IoT security remotely. Moreover, its capacity to model devices and configure the interconnectivity of devices and apps makes it a go-to instrument for safeguarding IoT systems.
You may release PoC IoT models more quickly thanks to this framework. You may determine if the project is viable and shorten the time it takes to launch. Furthermore, you may create IoT Security solutions and native apps with libraries, and customizable and pre-built widgets. Moreover, it has a secure architecture and is built on the reliable Dart language. They increase the app’s security.
The hardware prototyping platform comprises open-source projects. “Create” lets users build prototypes of electronic devices. “Studio” gives clients the working IoT development environment they need. “Connect” lets you link phones and stands with IoT gadgets.
This visual tool connects hardware devices, APIs, and services to help you step up your IoT security. Node.js appears as its foundation. Unlike a centralized platform, you may use this app on your own server. Moreover, if you require more customizable functions, you may use this tool similarly to other IoT platforms, such as IFTTT.
How to Strengthen Cybersecurity for IoT Devices and Networks
Having a few useful security tools on hand is helpful. However, learning how else you may ensure the protection of the devices and networks is also worthwhile. Let’s dwell on the most popular practices:
Develop and enforce guidelines for IoT devices
Implement strong authentication mechanisms to ensure that only authorized users and devices can access and control IoT devices. Employees must understand how to reset and utilize them. What’s more, you’ll also be able to audit and control the devices to support your organization’s digital safety.
Implement end-to-end encryption
It’s crucial for safeguarding data transmission in IoT, especially with protocols like MQTT lacking built-in security. Utilizing security certificates or establishing a single IPSec connection addresses the vulnerability, ensuring comprehensive data protection for confidentiality, authentication, integrity, and privacy. These measures enhance trust and security throughout the entire data transmission process.
Use effective risk mitigation techniques
They include putting in place a zero-trust architecture. It guarantees the granting of just necessary access for operations. A complete security approach starts with solid device authentication procedures and the incorporation of advanced technology like identity-based safeguards. Zero Trust Network Access (ZTNA) adoption also decreases the total susceptibility of unsecured IoT devices.
Turn off extra features like voice control, location tracking, and remote access
These functions may increase the attack surface and expose gadgets to security risks. Limiting or turning off these functionalities and only using them when necessary is best.
Moreover, another security measure is to separate and isolate IoT networks from the core infrastructure. It prevents unwanted access. Setting up separate network segments for IoT devices discourages attackers from moving laterally. By clearly defining borders, the segmentation lessens the effect of security breaches. Additionally, it helps businesses monitor network traffic properly and impose strict access rules, improving overall security.
Tips to Step Up IoT Cybersecurity
We’ve prepared top tips to help you improve IoT implementation and cybersecurity operations. They will always come in handy — early in your journey in cybersecurity or even at the moments of use:
