Changes to the current compliance and regulatory requirements are expected soon. These changes will support the security of IoT devices.

More Security Awareness

It is expected that there will be more security awareness and training for individuals, companies, and governments on the proper security practices for protecting data and privacy on IoT devices. These practices include using strong passwords for your IoT devices and how to detect vulnerabilities.

Types of IoT Cybersecurity

• Regulatory Compliance: Individuals and companies must comply with standards and regulations. You will align the IoT device with legal and industry standards.
• Physical Security: This ensures that IoT devices are protected from unauthorized access to the IoT Device location and physical attacks
• Cloud Security: This Secures every cloud infrastructure that supports IoT technology.
• Authentication and Authorization: This helps control IoT device access. Create a strong password, avoid weak passwords or hard-coded passwords, and use multi-factor authentication.
• Endpoint Security: This secures all the endpoints between the IoT devices and other network resources.
• Data Security: This protects stored and transmitted data on IoT devices.
• Device and Network Security: This helps to protect the network and devices against unauthorized access and malicious attacks. It secures communication between IoT devices and other systems.

Different Forms of IoT Cybersecurity Threats

#1) Distributed Denial of Service (DDoS) Attacks

A malicious person may try to disrupt normal IoT operations, by trying to exploit vulnerabilities in the system and flooding the IoT systems with false requests that may overwhelm the system and make them unresponsive to positive requests, thereby disrupting crucial business operations that could lead to financial and reputational losses.

#2) Botnet Attacks

Attackers hijack IoT with poor security networks and now use them to create sophisticated botnets that can be used for different malicious activities like spamming, and DDOS attacks and they can spread more malware on a global scale.

#3) Man-in-the-Middle Attacks

When an IoT security network is poorly configured, an attacker tends to hijack or eavesdrop on what is going on within it. This vulnerability allows them to collect sensitive data for their malicious act. This attack has caused severe financial and reputation damage to organizations.

#4) Malware Attacks

Malicious software attacks on IoT devices are on the increase. Malware can quickly spread to all devices on the network, thereby compromising the confidentiality, integrity, and availability of IoT devices. Let’s assume there was a ransomware attack on IoT devices. This type of attack would make the device unusable, and there could be a payment demand before it can be functional again.

#5) Credential Attacks

Avoid the use of weak or default passwords, this is one vulnerability that an attacker looks out for. They believe that once they can gain unauthorized access to an IoT device or network, then they can conduct malicious activities like changing the IoT configuration settings, setting up sophisticated botnets, stealing sensitive data, and many more.

#6) Firmware Attacks

An Attacker should not be able to access the IoT firmware; once they do, they can drop backdoor malware that will always give them unauthorized remote access and control over the entire IoT operation.

#7) Side-Channel Attacks

An attacker uses a side-channel strategy on the IoT mechanism by observing what goes on within, collecting relevant information, and then analyzing the information leakages in the IoT device during operation. These attacks can expose some very sensitive data, like encryption keys and many more.

#8) Encryption Attacks

Data encryption is a critical security measure that must not be negated but be taken seriously because it’s one of the best ways to protect sensitive information in IoT. It helps to secure every communication between IoT devices, other network resources, and users. Never allow an intruder to conduct encryption on your IoT device.

#9) Brute Force Password Attack

Never use a weak and default password for your IoT device. Attackers are always looking for password vulnerabilities within a system. Several software can generate many password combinations to carry out a brute-force attack. Once an attacker successfully performs this attack, he can steal confidential data and conduct other malicious activities on the system.

#10) Physical Attacks

It is very important to have physical protection for IoT devices that are crucial to an organization’s daily operations. Once a malicious person gets hold of essential IoT he can cause physical damage to it, which may cause the device to malfunction and cause business operation breakdown.

Why is Cybersecurity Important in IoT

Cybersecurity is very important, considering the benefits IoT devices bring to individuals and organizations. The current amount of IoT shows a higher risk of malicious attacks, such as unauthorized access and data breaches.

One major use case for IoT today is the capability to house extremely sensitive information. Just one unauthorized access or system hack could disrupt an organization’s entire network operation. If a malicious person discovers an IoT has a weak network mechanism, he will retrieve intelligence or cause physical damage to the entire network.

Implementing and enhancing a strong security posture and measures is very important to protect the confidentiality, integrity, and availability of IoT Devices. This process ensures and creates a safer and more reliable IoT ecosystem.

How to Enhance Security Measures for IoT Devices

Due to the high rate of the use of IoT, there are new security risks and challenges that warrant deep knowledge of different defense strategies that can be used to effectively address the problem.

The following ways are different ways individuals and organizations can enhance security measures for IoT devices:

• Security Enhancement Systems: Use Intrusion Detection Systems (IDS) that can quickly alert you against malicious attacks on your IoT Device. Deploy Intrusion Prevention Systems (IPS) to prevent network-based attacks. A security information and event management (SIEM) system can also help you get security attack logs.
• Adding Security Features: Some IoT devices have the capacity for security add-ons to be added to them. This security feature can help encrypt stored data and the one that flows between devices. There must be an authentication process implemented on the device to protect against unwanted device access, which can also help control connections to the device. Adding this feature will help to partition IoT traffic so that it can be easily controlled and managed.
• Follow Security Standards and Guidelines: Organizations like OWASP and the National Institute of Standards and Technology (NIST) have published many cybersecurity standards and guidelines for users and manufacturers of IoT devices.
• Device Visibility: Individuals and organizations usually lack visibility into what is going on in connected IoT devices. Sometimes, a stranger or employee may connect unauthorized objects to an IoT device, exposing the device to attack. An inventory of all IoT devices on your network is needed so that appropriate endpoint security can be deployed.
• Implement Zero-Trust Policy: When your IoT devices can be accessed on the same network as other network resources, they can be a potential vector for malicious attackers to exploit. The solution would be segmenting or separating the IoT devices from the general network that contains other non-IoT Devices and implementing a zero-trust policy on the IoT network.
• Implement Updates and Patch Management: Regularly install updates and conduct patching management. This is done to fix any IoT device that has vulnerable software and firmware.
