IoT (INTERNET OF THINGS) devices were created in 1999. Since then, companies are continuously adding more and more IoT devices in their workspace as these devices make work a lot easier and faster. IoT devices are constantly upgrading with new features. The toaster is considered the first IoT device introduced in the market. And now there are thousands of IoT devices present in the market, for example, air quality sensors, Wi-fi typewriters, smart tennis rackets, etc.
The future of IoT devices is bright. According to Gartner, IoT devices are increasing rapidly at 21% per year(double every four years). Currently, there are almost 10.07 billion IoT devices installed worldwide. It is estimated that the count will increase up to 30 billion by 2025.
IoT devices are the new future, but many risks are involved because of the lack of cybersecurity and possible cyberattacks. Many networks are involved in connecting IoT devices worldwide, which brings a massive threat to securing data stored in the devices from cybercriminals.
Because the huge number of IoT devices are connected worldwide, there is a significant chunk of networks untouched and undetected, resulting in a massive threat of cyberattacks. For cybercriminals, it is easy to hack the system.
Because of the increase in demand for IoT devices, manufacturers tend to overlook their security and management. This has led to the lack of visibility and security of the devices. The devices are not successfully tracked, which results in unsecured data.
The industries are rapidly increasing the number of IoT devices in their sector because of the advancement of artificial intelligence and machine learning. But with advancement comes in-built security risks that leave data stored in IT and IoT devices in an unsecured state.
According to the Department of Justice’s Cybersecurity Unit, “once infected, IoT equipment can be used to launch large-scale botnet attacks that threaten the stability and performance of private networks.” Companies need to understand devices’ security systems and bring up regular updates to avoid any cyberattacks to avoid such situations.
5 MAIN REASONS IOT DEVICES ARE VULNERABLE TO ATTACKS
As organizations embrace IoT technology, security challenges are growing. These five critical factors explain why IoT devices remain a prime target for cyberattacks.
1. PRICING ISSUE
Many companies prioritize cost savings when purchasing technical equipment, often opting for cheaper IoT devices that lack strong built-in security features. While these low-cost options may reduce expenses upfront, they expose organizations to higher risks of data breaches and cyberattacks.
Investing in devices with integrated security may seem costly, but it ensures stronger protection for sensitive company data, safeguards business operations, and minimizes long-term cybersecurity risks.
2. UNSECURED NETWORK
Not all networks used for data sharing across the world are properly secured. A large portion of these networks operate without adequate visibility, making them an easy target for cyberattackers who exploit hidden vulnerabilities.
Unsecured networks create opportunities for attackers to intercept sensitive data, gain unauthorized access, and move laterally within corporate systems. Without strong encryption and continuous monitoring, businesses risk exposing their critical information and leaving their IoT devices vulnerable to sophisticated cyber threats.
“Attackers are using IoT for lateral movement. They go through these devices in a network and try to reach an entry point or a segment of the network with valuable information. That east-west lateral movement is the most difficult. Cyber Attackers are taking advantage of the vulnerable nature of the IoT devices to pivot or propagate within the network.”
3. IMPROPER DATA TRANSFER AND STORAGE
Data transfer and storage today involve thousands of networks spanning the globe, and not all of these networks are properly secured. This lack of protection significantly increases the risk of sensitive data being intercepted or stolen by cyberattackers.
In addition, personal information is often stored and processed through third-party cookies used by digital marketers, further raising the chances of data leakage. Without robust encryption, secure transfer protocols, and controlled storage practices, organizations and individuals remain highly vulnerable to cyber threats and potential breaches of confidential information.
4. IRRESPONSIBLE MANAGEABILITY
Irresponsible manageability occurs when manufacturers overlook the critical importance of properly managing IoT devices throughout their lifecycle. Many manufacturers rely on third-party vendors with insufficient expertise to handle device security, rather than employing reliable and credible management solutions.
This lack of accountability can result in misconfigurations, delayed security updates, and increased vulnerability to cyberattacks.
Ensuring proper management, regular monitoring, and using trusted security frameworks are essential to protect IoT devices and safeguard sensitive company data.
5. WEAK PASSWORDS
Weak passwords remain one of the most common vulnerabilities in IoT devices. Many devices are shipped with preset usernames and passwords provided by the manufacturer, which are often publicly available.
Cyberattackers can easily exploit these default credentials to gain unauthorized access, steal sensitive information, or move laterally across networks. To protect the data stored in devices and reduce security risks, manufacturers must enforce stronger authentication measures, require password updates, and implement robust access control policies.
HOW TO SECURE IOT DEVICES: 7 RECOMMENDED METHODS
Securing IoT devices requires a comprehensive and proactive approach.
From regular updates to controlling accessibility, these seven recommended methods help businesses safeguard their connected devices against cyberattacks, protect sensitive data, and maintain reliable network performance.
1. UPDATING DEVICES REGULARLY:
Manufacturers of IoT devices frequently release security updates and patches to protect devices from emerging cyber threats. These updates often address vulnerabilities, fix bugs, and enhance overall system security. End-users and organizations should prioritize installing these updates promptly and consistently, rather than delaying or ignoring them.
Regular updates ensure that devices remain resilient against evolving attack strategies, safeguard sensitive data, and maintain the integrity and reliability of the connected network. By staying proactive with device updates, businesses can significantly reduce the risk of unauthorized access and potential security breaches.
2. ISOLATION ISN’T ENOUGH:
Often, traditional IoT security involves the removal of compromised devices from the network. The security system merges with firewall and Network Access Control to remove compromised devices to lighten the cyber attacks. Though the process is effective in preventing a breach, it has the side effect of disrupting the expected performance of the device, which can result in an easy path for attackers to attack.
3. AUTOMATION OF THE RISK EXPOSURE:
Industries need to allow their system admins to perform device up-gradation, such as updating the latest firmware version and changing passwords and configurations. It allows the security team to acknowledge the possible attacks before it happens. This approach helps to reduce possible cyber threats and costs per incident.
4. CONSTANT DEVICE MANAGEMENT:
IoT devices are the most vulnerable to attack, especially when there is a lack of visibility in the network. The security team can prevent cyber attacks by understanding the devices connected to their networks and properly managing them. If cyberattacks happen, proper management of devices will allow you to detect and track them quickly and react instantly.
5. PROACTIVE APPROACH:
With evolving IoT technology, industries have a constant demand to have a proactive approach towards device security. By understanding the security needs, such as real-time event tracking, industries can protect their devices from future cyberattacks and secure their data from cybercriminals.
6. AVOIDING PUBLIC WI-FI NETWORKS:
IoT devices such as mobile phones, smartwatches, etc., must not be connected to public wi-fi networks as they are the most insecure network. Although it may be tempting for users to use free data, it is risky for their personal information.
7. ACCESSIBILITY OF THE IOT DEVICES:
Enterprises should make sure that their IoT devices are only accessible to their employees. Identity security practices, including passwords and biometrics, can help ensure device safety.
As IoT innovation progresses and develops, the requirement for IoT security arrangements will keep on upholding changes on how various enterprises will utilize IoT devices in their surroundings. By enterprises understanding the distinctive security difficulties and dangers that IoT devices accompany, they will be better positioned to receive the benefits of IoT innovation.
