The Internet of Things (IoT) refers to the network of physical devices that connect to the internet and can communicate with each other or with other systems over the web. These devices collect, send, and receive data, enabling smart functionality in a variety of applications.
Examples of IoT Devices:
- Smart Thermostats: Devices like the Nest thermostat learn user preferences and adjust heating and cooling systems automatically.
- Security Cameras: Connected surveillance cameras that allow for remote monitoring and real-time video feeds.
- Industrial Sensors: Sensors used in manufacturing to monitor equipment health and automate processes.
- Smart Lighting Systems: Lights that can be controlled remotely via apps or automated schedules.
- Healthcare Devices: Wearable fitness trackers, heart rate monitors, and other medical devices that collect and transmit health data.
While IoT devices can significantly improve efficiency and convenience, they also introduce new challenges and vulnerabilities into corporate networks.
How might this be? Given that many IoT devices are designed with cost efficiency in mind, manufacturers at times compromise on out-of-the-box security features and ongoing software updates. This can make them prime targets for cyber attackers looking to exploit vulnerabilities. To protect your network, it’s crucial to implement best practices for IoT security.
Best Practices for Securing IoT Devices
- Segment IoT Devices
To protect your corporate network, isolate IoT devices either logically (using a firewall) or physically (with an air gap). This segmentation ensures that IoT devices only have access to the specific resources they need, reducing potential attack surfaces. - Ongoing Vulnerability Scanning
Regularly scan your network to identify any vulnerable IoT devices that may have been granted more access than necessary. Continuous monitoring helps you stay ahead of emerging threats, allowing for prompt action to mitigate risks. - Implement Strong Authentication
Ensure that all IoT devices are protected by strong authentication protocols. Use unique, complex passwords and enable multi-factor authentication (MFA) where possible to prevent unauthorized access. - Keep Firmware and Software Updated
Manufacturers may release patches and updates to fix security vulnerabilities. Regularly check for and apply these updates to all IoT devices to minimize the risk of exploitation. - Disable Unnecessary Features
Many IoT devices come with default features and services enabled, which may not be necessary for your business needs. Disable any unused features to reduce the attack surface and potential entry points for attackers.
IoT devices bring significant benefits to businesses, but they also come with security risks that must be managed carefully. By understanding what IoT devices are and following these best practices for securing them, you can better protect your network from potential cyber threats.
