One of the biggest concerns of IoT is managing the risks associated with a growing number of IoT devices. Information security and privacy issues related to IoT devices have attracted global attention, because of the ability of these devices to interact with the physical world.
“IoT vulnerabilities have been discovered and exposed across many industries,” says Oleksii Tsymbal, Chief Innovation Officer at MobiDev. “These vulnerabilities threaten sensitive data as well as personal safety. Without a doubt, the Internet of Things is a prime target for hackers in the 2022, and any organization that produces or uses these devices needs to be prepared.”
The company’s experts briefly review some of the common cybersecurity threats facilitated by IoT devices. Among common threats are:
- IoT botnets – hackers who compromise millions of devices, connecting them into a network they can use for criminal activities.
- Data exfiltration – attackers can access the device data and steal any sensitive information. They also leverage IoT to harvest credentials from device firmware.
- Shadow IoT, which arises because IT administrators do not always have control over devices connected to the network.
These can be mitigated, says the company, by following IoT security best practices:
- Security Analytics – A security analytics infrastructure can significantly reduce vulnerabilities and security issues related to the Internet of Things. This requires collecting, compiling, and analyzing data from multiple IoT sources, combining it with threat intelligence, and sending it to the security operations center (SOC).
- Network Segmentation – Network segmentation is a technique that enables isolation of specific components from others, to improve security. In the case of IoT, segmentation can help prevent attackers or malicious insiders from connecting to IoT devices, or can prevent compromised devices from infecting other parts of the network. You can implement this technique into your strategies or use a network security solution.
- Device Authentication – Another way to reduce the vulnerability of IoT devices to attacks by enforcing full authentication on all devices. Whether your IoT devices have simple password authentication, or more advanced measures like digital certificates, biometric, or multi factor authentication (MFA), use the most secure authentication.
- AI and ML for IoT Security – Being the one of the recent IoT trends, AI-based Intrusion Detection Systems (IDS) continuously monitor the network, collecting and analyzing information from previous attacks. They can predict an attack based on the historical data and suggest a solution to fight the threat. Even new hacking techniques are made up, they still may include previously used patterns, which can be recognized with ML algorithms in real-time.
