Three Effective Methods for Securing IoT Devices Against Cyber-Attacks

This is the era of Artificial Intelligence (AI), automation, and the Internet of Things (IoT). More and more businesses are transforming their operations and preparing to weather the digital transformation storm. This change paved the way for IoT devices and their widespread adoption.

The Internet of Things (IoT) or smart devices — objects that can access the internet to send or receive data have been some of the most intriguing and beneficial consumer technologies developed in recent years.

IoT gadgets, on the other hand, can provide a slew of new issues for companies. Each of these devices provides another avenue for hackers to attack the network. To make matters worse, as compared to smartphones and laptops, IoT devices are notoriously difficult to secure.

Here are a few things that businesses should consider when it comes to securing IoT devices.

Utilize device discovery for full visibility

The first thing an enterprise should get to the bottom of is how many IoT devices are linked to its network. Discover which devices are linked to the network and maintain a complete, up-to-date inventory of all connected IoT assets, ideally using a dedicated IoT security solution to ensure all devices are verified.

Firms should gather information on each device’s manufacturer and model ID, serial number, hardware, software, and firmware versions, as well as information on the underlying operating systems and settings. Furthermore, businesses must establish each device’s risk profile as well as its behavior in relation to other connected devices. These profiles should aid in segmentation and the creation of next-generation firewall policies. Companies should update their asset map with each new IoT device connected to the network.

Avoid employing Universal Plug and Play

While Universal Plug and Play (UPnP) has its advantages, it also exposes printers, routers, cameras, and IoT devices to cyber-attacks. The goal of UPnP is to make things easier to network devices without requiring additional configuration and to enable them to discover each other automatically. However, this is more beneficial to hackers than anything else because it allows them to discover all IoT devices outside the local network. As a result, it’s recommended to disable UPnP entirely.

Modify default passwords and settings

When installing or upgrading an IoT device, it’s a good idea to turn off any access or connectivity functions that a company doesn’t want or require. For example, multiple devices by default will try to link to other nearby devices and networks.

While this can make setting up a smart office easier, it can also leave a significant security gap. Via the insecure IoT devices, cybercriminals and unauthorized users might just connect to the network.

Many IoT devices also include password protection features that restrict network users from altering security settings or accessing the device without the correct password. On the other hand, these gadgets frequently come with default passwords that the user may not be required to update when the device is first turned on.

Hackers can repeatedly guess default passwords or use manufacturer tools to find the device’s password, giving them access to its functionality. Changing an IoT device’s default password towards something unique and secure will help keep it safe.
