Securing IoT Devices: Best Practices for Businesses

How Can I Secure My Employees’ IoT Devices?

Industries are being transformed by the Internet of Things (IoT), increasing operational efficiency and customer experiences and creating new business opportunities. But the more we weave these smart devices into every facet of life, it seems that their breeding ground is growing along with them. With the amount of vulnerabilities and these devices being integral to your business there is a clear need for securing IoT.

Introduction to IoT and Importance

IoT may be the acronym for this Inter-space of items, along with also an interconnect system which can make it possible to join all one’s favorite physical apparatus into the net decided on and command utilizing a cell gadget. That runs the gamut from consumer products like smart thermostats and wearable health monitors to internal industrial equipment and supply chain solutions.

Why Businesses Need IoT?

Operational Efficiency: IoT automates processes and helps in obtaining real-time data for informed decision making.

Customer Experience: IoT offers a host of customer-related benefits, from smart retail shelves to more efficient customer support systems that improve overall interaction and experience for customers.

Innovative Opportunities: Data generated by IoT devices provides new insights for businesses to innovate and create a different source of revenue.

The advantages are obvious, but the disadvantage is that IoT means a new attack vector for cyber criminals. So, it is crucial to apply strong security measures in order to safeguard these devices and also enterprises’ entire network.

Common Security Vulnerabilities In IoT Devices

The first step in managing risks lies with identifying and understanding security vulnerabilities powered by IoT devices. Here is a list of the more common vulnerabilities:

In Terms of Best Practices for IoT Security

Because IoT devices vary so widely, based on the purpose they serve in their environment, businesses must take a complete security approach to these endpoints. Here are some best practices:

1. Use of Strong Authentication Methods

2. Encryption for Data at Rest and in Transit

3. Frequently Update Software and Firmware

4. Network Segmentation

5. Physical Security

6. Monitor and Respond

7. Employee Training

8. Rent Security Solutions

IoT Security Breaches Case Studies

It can not only be eye-opening to look at previous IoT security breaches but it also serves as a reminder of the importance of practicing good safety measures.

Case Study 1: Mirai Botnet Attack

In 2016, the Mirai botnet attack happened through commanding IoT gadgets with default passwords and the number of devices compromised was well-passed over half a million. These compromised devices were then used to launch DDoS attack campaigns resulting in huge internet outage across the world. It reminded us to change the default passwords, use better authentication mechanisms.

Case Study 2: Jeep Cherokee Hack

In 2015, security researchers showed it was possible to control a Jeep Cherokee remotely via its IoT system and perform sensitive operations such as steering or braking. This security issue was a result of the use of insecure software and unreadable communications channels. The case demonstrated the importance of frequent software updates and safe communication protocols.

Case Study 3: Stuxnet Worm

In 2010, the incoming of Stuxnet was a herald to come smashing at Iran’s nuclear program using an advanced worm that targeted industrial control systems (ICS). This attack leveraged known, and unpatched vulnerabilities in ICS devices highlighting the need for ongoing monitoring of IoT systems such as these.

Conclusion

When the smoke and mirrors of technical functionality give way to a business strategy, protecting IoT devices is paramount. Understanding common vulnerabilities and taking the appropriate precautions go a long way in protecting enterprises against some of IoT devices’ worst risks. Additionally, being able to lease firewalls, servers, and routers allows businesses to secure their IoT infrastructure without a lot of upfront capital investment. In summary — Updates, Strong Identity Based Authentication / Encryption, and Continuous Monitoring are your partners in defending the IoT landscape. IoT security is a chain, so taking proactive measures doesn’t only safeguard your own assets but also helps in confidence building with your customers and partners.
