The advent of cloud-based solutions changed the nature of digital security. But with the benefits of cloud-based solutions, organisations are now integrating another rising solution with cloud computing. And that happens to be the Internet of Things (IoT).

The IoT has slid itself as a perfect fit in the world of remote startups. The combination of these two services has practically taken over industries across the globe.

IoT provides interaction with physical devices. And the connectivity of the information within devices is provided by the cloud. So a cloud-based IoT platform provides the connectivity to help devices in different settings function together.

But, with the merging of IoT devices and cloud computing, it's essential not to overlook the security risks. So, what does cloud-based IoT software mean in terms of security?

Combining IoT and cloud computing does not immediately solve the risks associated with the ecosystems. For example, adding an IoT ecosystem introduces a physical aspect of security due to the devices at the user end.

While creating a secure cloud-based IoT platform, here are some challenges that an enterprise may face,

1. Privacy and Authorization issues

The need for end-to-end encryption and multi-factor authentication is more emphasized than before. In addition, it restricts intruder entry and access to information unless the right personnel is present.

2. Misconfiguration of cloud and edge services

Without authentication and encryption, the data transmitted between the cloud or two points in the IoT ecosystem is at risk. The device or the cloud server can be exposed, leading to a perfect loophole for data breaches.

Further, cloud attacks such as Trojans, SQL injections, and others may occur if the cloud platform cannot detect them. Hence, choosing a cloud provider that ensures such attacks are notified and taken care of is necessary.

3. Poor implementation of IoT tools and platforms

An IoT system has its own set of security measures. If you misuse or update it without care, this process's weaknesses in this stage are with the integration into the cloud. It makes the cloud system vulnerable to attacks as well.

Security measures such as changing default passwords or securing physical devices using IoT must be a priority. In addition, using protocols such as OAuth 2.0 can also help protect the IoT ecosystem.

The convergence of the IoT and cloud platforms leaves loopholes in the digital and physical sectors. For example, there can be physical attacks, network and channel attacks, cryptanalysis attacks, etc.

Hence, ensuring a high degree of security is necessary. Here are some methods to ensure the safety of Cloud-Based IoT software,

1. Encrypt data in rest and transit

IoT and cloud security, data at rest and transit need to be secured. Encryption technologies such as HTTPS, FTPS, SSL, and TLS can employ end-to-end encryption. It ensures that the data in transit and passes networks and servers are protected.

It also ensures that data stored on any disk or backup device is secured. For these, you can use several layers of encryption. It provides that even when an attacker obtains access to storage devices with confidential data, they would not be able to decipher it.

2. Device identity and authentication

Assign device identity to each device in an IoT platform. That way, when the device is online, it can be identified and authenticated to establish communication with the other devices in the environment securely.

For instance, OAuth 2.0 is a token-based authentication used by API developers to protect an IoT ecosystem. If these security features are not present, the integrity of the data sent between two devices or points may be at risk.

3. Ensure vulnerability checks and continuous updates

Regularity with updates and vulnerability checks is a crucial method to ensure security. Testing the entire ecosystem can figure out any loopholes or issues present prior. In addition, conditions updates and patches can prevent the exploitation of IoT vulnerabilities and provide regular software updates for newer features.

4. Hardware security

The physical component of security is present in an IoT ecosystem. Install chips such as Trusted Platform Modules (TPM) and Trusted Execution Environment (TEE) on the devices. It is attached near the CPU or the device and ensures disk encryption and password protection. In addition, it creates a security key and stores the data effectively.

5. Establish a chain of trust

For IoT tools and platforms, establishing a chain of trust is a step toward a higher degree of security. This chain includes devices, gateways, and applications that are a part of the IoT ecosystem.

6. Define a detailed access control plan

A user management system is the first step to stringent authentication processes. Having the right policy in place can prevent unauthorized access and allow minimal access in the case of confidential data. In addition, the administrator can control the devices and define the accessibility and level of resources for different employees.

Even when starting with IoT tools and platforms, being wary of security should be a priority. Be it different technologies or ones that the cloud provider uses. Enterprises need to make sure that their entire cloud IoT system is secure.

Peer-reviewed checks and software updates are crucial. They help track down any loopholes or issues within the system. In addition, updates help procure the latest software versions with updated security features.

Further, a clear access control plan helps users and groups have defined roles for authentication and access to data. Limited access to confidential information is critical. Within the team, best practices and policies must be enforced and encouraged.

The IoT ecosystems and linked cloud services require secure passwords to remain free from data breaches. In addition, implementing monitoring and filtering tools at the IoT devices helps data assessment and monitoring early in data input and transit. As a result, you can quickly detect any suspicious activity or attempt entry from the device.

Cloud Based IoT seems to be the future, and if you're an organisation that already has it, you have the chance to create a future-proof security system. Merging physical and digital security protects your enterprise data from all vulnerabilities. In addition, updating security protocols within the IoT cloud ecosystem and workplace is key to keeping your Cloud Based IoT software secure. In short, the security of the infrastructure and the cloud system must always be a priority.
