The Internet of Things (IoT) is revolutionising the way businesses are operating, with many companies now having a large amount of IoT devices connected to the internet. However, managing and securing these devices can be a daunting and complex task.

From basic device security to long-term management strategies, there is a lot to consider when it comes to managing IoT devices in an enterprise setting.

In this blog post, we’ll take a look at the key principles of enterprise IoT device security and lifecycle management, from selecting secure hardware and software to developing a holistic cybersecurity strategy.

We’ll also look at best practices for ongoing device maintenance and lifecycle management, so you can keep your network safe and secure for years to come.

The Need for IoT Device Security

The Internet of Things (IoT) is one of the fastest growing areas of digital transformation. In 2023 it is predicted that there are almost 15.14 billion connected devices. This explosive growth has created new security challenges for organizations that are looking to adopt IoT technology.

One of the biggest concerns with IoT devices is that they are often lack adequate security protocols. Many devices are shipped with default passwords and little to no security features. This makes it easy for hackers to gain access to a network by targeting these devices.

Another concern is that IoT devices generate a large amount of data. This data can include sensitive information such as customer records or proprietary company information. If this data falls into the wrong hands, it could be used to exploit an organisation or its customers.

Finally, IoT devices have a short lifespan compared to other types of technology. This means that organizations need to carefully manage the lifecycle of their IoT devices to ensure that they remain secure and compliant with regulations.

Organizations must take steps to secure their IoT devices and protect the data they generate. Failure to do so could result in serious consequences such as data breaches, financial losses, and reputation damage.

The Benefits of Enterprise IoT Device Security

The benefits of enterprise IoT device security and lifecycle management are manifold. By deploying a centralised platform to manage all aspects of their IoT devices, organizations can enjoy increased visibility and control over their endpoints, enhanced security against cyber threats, simplified compliance with industry regulations, and much more.

Organizations that implement an enterprise IoT device security solution can immediately experience the following benefits:

Increased Visibility and Control

A centralised platform provides organizations with a simplified system through which they can view and manage all of their IoT devices. This gives them complete visibility into their deployments, so they can quickly identify and remediate any issues.

Enhanced Security

Through securing each individual IoT device, organizations can better protect their data and networks from cyber threats. Additionally, a centralised platform enables organizations to quickly deploy security updates and patches to all of their devices at once, ensuring that they are always up-to-date.

Simplified Compliance

Industry regulations surrounding IoT are constantly evolving. A centralised platform helps organizations to stay compliant by providing them with the latest information on required security measures. Additionally, many platforms offer built-in compliance reporting capabilities, so organizations can easily generate the necessary reports for auditors.

The Risks of Not Securing Your IoT Devices

As the Internet of Things (IoT) continues to grow, so do the risks associated with not securing IoT devices. Unsecured IoT devices can be used to launch attacks on networks and systems, steal data, and cause physical damage. IoT devices are also often used to access sensitive data and personal information, which can be used for identity theft and fraud.

There are a number of ways to secure IoT devices, but it is important to choose a solution that fits the needs of the organisation. Some common security measures for IoT devices include device management platforms, data encryption, and two-factor authentication.

Device management platforms provide a way to centrally manage and monitor IoT devices. Data encryption ensures that data is protected from unauthorised access. Two-factor authentication adds an extra layer of security by requiring users to enter a code from a second device in order to access data or applications.

Organizations should also have policies in place for how to handle IoT device security threats. These policies should address how to identify and respond to security breaches, as well as how to prevent future attacks. One suggested framework is to implement Zero Trust architecture, to identify and manage both device and user to monitor the entire IoT ecosystem.

Unsecured IoT devices can be hacked and used to launch DDoS attacks, steal data, and more. In addition, unsecured IoT devices can also be used to access sensitive information or control systems. This can lead to serious consequences, such as data breaches, system outages, and even physical damage.

To mitigate these risks, it is important to implement security measures at all levels of the IoT device lifecycle – from design and development to deployment and management. This includes ensuring that IoT devices are properly configured and secured before they are deployed, as well as continuously monitoring them for vulnerabilities. Additionally, it is important to have a plan in place for how to deal with compromised IoT devices.

By taking these steps to secure IoT devices throughout their lifecycle, enterprises can help protect themselves from the many risks associated with unsecured IoT devices.

How to Secure Your IoT Devices

Within each enterprise there may be many connected smart devices, so it’s important to make sure they are all secure. Here are some tips on how to secure your IoT devices:

1. Use strong passwords and enable two-factor authentication.

2. Keep your devices up to date with the latest security patches.

3. Use a VPN or other encryption method when connecting to public Wi-Fi networks.

4. Don’t use default settings for any of your IoT devices.

5. Consider using a personal firewall for additional protection.

6. Install security software on all of your devices, including PCs, laptops, and smartphones that have access to your IoT devices.

Importance of Public Key Infrastructure to IoT Security 

Public Key Infrastructure (PKI) is a key component of enterprise IoT device security and lifecycle management. PKI enables the secure exchange of data between devices and helps to ensure the authenticity and integrity of data transmissions through digital certificates provided by a certificate authority. PKI also provides a mechanism for revoking access to data in the event that a device is lost or stolen.

PKI plays a vital role in IoT security by providing a way to authenticate devices and protect data communications. By using digital certificates, businesses can be sure that only authorized devices can access their network and data. PKI can also be used to encrypt data and secure communications with a cryptographic key, ensuring that sensitive information stays confidential.

With the increasing number of IoT devices being deployed, it’s important for enterprises to have a robust PKI solution in place. A good PKI solution should be scalable, with a certificate management system so that it can support a large number of devices, and it should be easy to manage so that businesses can quickly add or remove devices from the system as needed.

An effective PKI solution is an important part of any enterprise IoT security strategy. By using PKI, businesses can ensure that only authorized devices have access to their networks and data, and that communications are encrypted and confidential.

The Enterprise IoT Device Lifecycle

The first step in ensuring the security and proper lifecycle management of enterprise IoT devices is understanding what types of devices are in use and what each one requires. Once that understanding is in place, enterprises can develop comprehensive policies and procedures for managing these devices throughout their lifespan.

Key Stages of the IoT Device Lifecycle

When it comes to the actual lifecycle of an IoT device, there are three primary stages: deployment, operation, and decommissioning.

Let’s take a closer look at each stage:


This is the stage where the device is installed and configured for use. It’s important to ensure that all security settings are properly configured during this stage. This is also the time to establish baseline performance metrics so that you can identify any potential issues later on.


The enterprise IoT device lifecycle begins with the device’s initial deployment and continues until the device is decommissioned. In between, there are a number of steps that need to be taken in order to ensure that the device remains secure and properly functioning.

The first step is to deploy the device and connect it to the network. Once connected, the device will need to be configured in order to work properly. This includes setting up security features such as passwords and encryption keys.

After the device is deployed and configured, it will need to be monitored on an ongoing basis. This includes checking for firmware updates and patching any security vulnerabilities that are discovered. Additionally, the device’s logs should be monitored for unusual activity.

This is the stage where the device is actually being used by employees or customers. It’s important to monitor performance closely during this stage and to address any issues that arise promptly. Regular firmware updates should also be implemented during this stage to help keep the device secure.


This is the final stage of the IoT device lifecycle when the device is retired from service. All data must be wiped from the device before end of use, as well as revoke digital certificates.

From the time an enterprise IoT device is deployed until it reaches the end of its lifecycle, there are a number of security and lifecycle management considerations that need to be taken into account.

If at any point during the lifecycle of the device it is determined that it is no longer needed, it should be decommissioned in a secure manner. This includes wiping all data from the device and ensuring that it can no longer connect to any networks.


Enterprise IoT device security and lifecycle management is a complex topic, but it doesn’t have to be overwhelming. By utilising the strategies outlined in this guide, you can ensure that your organisation’s devices are secure, up-to-date, and well managed throughout their lifecycle. With the right strategies in place, you’ll be able to maximise the value of your enterprise IoT investments while also protecting them from attack.
