IoT security devices have become an essential part of modern life. From medical devices to household goods, IoT-enabled goods and services are being used to improve people’s lives daily. However, IoT devices also pose a lot of security risks. Because these devices are usually connected to the Internet and can be remotely controlled by unauthorized individuals or companies, they can be susceptible to hacking and malware attacks. To combat this risk, businesses must implement an effective and secure digital identity management (DIDM) strategy across their supply chain platforms and IoT applications – from production environments to fulfillment centers and customer support services. Just like any other business asset.
Define and implement a security strategy
The security of a business’s network is crucial to its operation. If the network is poorly secured, stolen or misused, the company’s data and assets could be exposed to higher risks of theft, loss or damage. Therefore, the first step towards securing your network is clearly defining what data and assets are valuable and how they should be connected. This will help you identify the necessary steps to take and determine if your current security strategy adequately addresses the needs of your business. Businesses must clearly define their valuable assets such as customer data, financial information, internally-generated/controlled data, and confidential information. Data companies generate and should be well-protected with solid authentication and encryption techniques.
Restrict access to the right thing
A common mistake made by businesses is to grant all access to their assets to everyone. This often leads to frustration for employees who have to deal with a constant stream of users trying to use the computer they’re sitting in. If you only grant access to specific individuals who need to use the computer for specific purposes, you can reduce the risk of a security breach.

Regular software updates
When a business employs a Continuous Diagnostic and Retention (CDR) strategy, it can determine the need for and frequency of software updates for each platform in the supply chain. When it comes to distributed ledger technologies (DLT) such as the Blockchain, keeping the update frequency consistent with the business’s operational needs is essential. For example, a food company that wants to maintain its supply chain data integrity should update its DLT software at least once a month. On the other hand, if the company is engaged in manufacturing and only needs to adjust the software’s update frequency based on operational demands, it needs to adopt a more ad-hoc approach.
Device and service lifecycle management
After a device is manufactured, it should be treated as if it were a high-value asset. This means regular security assessments should be conducted on all IoT devices, both physical and digital, to determine their security status and recommend best practices for improving it. If a device is determined not to be secure, it should be replaced or repaired according to the manufacturer’s guidelines so that the data remains protected. The same goes for services like Google Analytics, which should be treated as if they were high-value assets. Regularly conducting assessments, replacing old or faulty equipment, and maintaining service agreements should all help protect your data.
Protect data at rest with cryptography
The Internet of Things relies on data being stored and processed in computers, smartphones or other devices. However, these devices can be connected to the Internet in many ways, such as through an ordinary phone line, powerline or Wi-Fi connection. As a result, data stored in these devices may be at risk of being stolen or misused. To protect data at rest with solid cryptography, companies that sell IoT devices should use encryption technologies like HTTPS, WEP, WPA or WPA2. These techniques will help prevent hackers from gaining access to sensitive data such as credit card numbers or financial account numbers. They will also keep data secure even if the hardware associated with the device ever goes out of service, is stolen or is destroyed.
Proactive malware detection and response
When a company’s data is stored on an IoT device, it’s typically in an unencrypted format. If a hacker gains access to this device, he or she could use it to access other data stored on other devices within the company—including financial data, customer information or even sensitive business information. To protect data at rest with solid cryptography, businesses that use IoT devices should implement an “implementation-as-code” security strategy. This approach will require the company to write code that will act as an access control gateway to the device, including the ability to log in users, revoke user rights and make sure sensitive data is encrypted.
Businesses communicate with each other often through networks, such as the Internet, mobile devices, and office computers. When communication between systems involves the use of unsecured means, such as the Internet, email, or telephones, it’s called “unauthorized” communication. Anywhere a business sends or receives information that could lead to exposure, it’s called an “unauthorized” communication channel. Unauthorized communication also happens when a business doesn’t have a specific need to communicate with another business—such as when a customer asks a company’s support team to look into a technical issue they have or when a colleague wants to ping a colleague working in your same space.
