The more devices we have linked to the network, the greater the need to consider the security elements and requirements for IoT accessories.
6 Security Elements to Consider for IoT Devices
Connectivity is critical to your IoT project’s success. IoT networks are by their very nature complicated, and cybercriminals can intercept them in a variety of ways. In order to fully defend an IoT network, we must consider the following security elements.
1. Access to the device.
Many IoT devices operate in unmanaged and insecure contexts. This allows hackers to upload malware and gain access to particular functions of the device. This, in turn, gives them the ability to harm the entire network. In addition, they can possibly gain access to unencrypted confidential data, and even transform the device into a botnet.
2. Signature of the device.
Attackers can, for example, clone a device’s identity to gain access to your data. Furthermore, they can even enter your entire system by infiltrating the network. Therefore, the device signature must be secure, one-of-a-kind, unchangeable, and fully unique. We can’t deploy IoT security on all other components of the network without adequate device identity management.
3. Data security.
IoT networks continuously transfer data, including sensitive and regulated data. This is self-explanatory. However, the security, privacy, and integrity of data in storage are vital. This included data on the IoT device, on the network server, and in the cloud. Any data in transit is vulnerable and therefore must be considered as an important aspect of IoT security. As a result, throughout the IoT lifetime, data security must be established across all devices and equipment.
“Commands” refers to the instructions sent to IoT devices. These instructions might activate features, command the device to execute certain functions, turn it on/off, and so on. These commands can be performed either by machine-to-machine automation or human input. Therefore, only verified persons and/or systems, including AI, should be able to provide commands to IoT devices.
5. Security of software decisions.
Algorithm-based or AI-based software decisions are used in IoT applications with automation. As a result, hackers can potentially disrupt the entire IoT network. They can do this if they intercept and modify these decisions. Therefore, to avoid this, all software decisions should be made in a secure environment. In addition, they should be done with proper anti-interception and anti-tampering protection.
6. Physical actions security.
Physical actions such as unlocking a smart lock or stopping/starting a device are common actions with IoT devices. They also include increasing/decreasing the temperature of HVAC equipment, for example. These common IoT deployments are places where security must be considered. These acts can be intercepted by hackers. Therefore, they may not only compromise the system but may also jeopardize the user’s safety. Furthermore, it’s critical to make sure that devices and equipment can only do these tasks if they receive authenticated commands.
6 Requirements for Security of IoT
As we can see, the IoT security elements require consideration in order to maintain security on any network. This is a large and complex process including multiple layers of protection. So, how do we know if an IoT system is “safe?” As the foundation of any IoT security endeavor, here are the key requirements of a secure IoT system.
1. Security Compliance Designed from the Beginning
Before everything else, all IoT devices must be secure in their design. Therefore, we must coordinate infrastructure (servers, routers, and so on) and software. Further, make sure that the design of anything on the IoT network has potential cybersecurity threats in mind. As a result, do not include any hardware or software solution in an IoT network if it is not safe by design. Even a single weakness might expose the entire system.
2. Managing Your Security
The first criterion is concerned with the IoT system’s human component. Ideally, a specialized team should be in charge of IoT security. However, at the very least, a designated executive should be in charge of safeguarding the six major parts of IoT outlined above. This person should be in charge of safeguarding all IoT devices and equipment. In addition, they should be concerned with the integrity and security of data in the IoT system. This includes customer information.
3. Purpose-Based Authentication and Authorization
Cryptography (authentication and authorization) functionalities must be part of the devices and software solutions. These should always be in accordance with industry standards and best practices. In addition, make sure you manage authentication and permission properly. This guarantees that they only grant access to the right people. In addition, they do so only when it is necessary for their current task. Therefore, to maximize IoT security, make sure to end authentication as quickly as possible when access is no longer necessary.
4. Framework for Secure Applications and Networks
There is another important part of IoT security. We must ensure that all apps, web interfaces, server software, and other network pieces are secure. Therefore, take measures to ensure data security and compliance with privacy regulations. Furthermore, if you use cloud network solutions in your IoT system, protect them as well.
5. Device Manufacturing and Supply Chain Security
We will suppose that the IoT device has security components. Therefore, it’s critical to ensure that the product we’re going to include in the IoT network is secure. As a result, always check for security through the manufacture, distribution, and/or installation processes. In addition, choose hardware and software solutions with acceptable warranty policies. The items should be safe and secure for end-users right out of the box.
6. Simple and Secure Setup
It’s critical to make sure that end-users can easily use and set up IoT products and equipment. Therefore, the configuration and control should assist the user and the IoT system’s manager in maintaining security. Regular software updates, particularly security updates, are another important security action. A clear and easy-to-understand vulnerability disclosure policy and life cycle management should all be provided by the product’s seller.
