Common IoT Security Risks and How to Mitigate Them

Chinmaya Choudhury / June 6, 2025

The Internet of Things (IoT) is rapidly expanding in India. Devices such as smartwatches, home security cameras, connected cars, and industrial machines are now pervasive in our lives. IoT Security Risks offer many benefits by sharing data and working autonomously. However, along with those benefits, smart devices present serious security challenges. Most IoT devices are designed with limited security functions. If a device is insecure, it is susceptible to being hacked or used in malicious ways. This may result in a loss of data, the ability to spy, or even damage systems as a result of the malicious act. In India, where the adoption of technology is exponential, securing IoT devices is critical. In this blog, we will look at the most common IoT security risks and explain how to protect your devices. Whether you are a business owner or a regular user, knowing about these risks can help you stay safe and make better decisions. What Is IoT Security Risks? IoT Security Risks is several best practices and technologies used to protect networks and devices from potential cyber threats. These connected devices have low processing power and often lack strong built-in security, and can be vulnerable to attacks. So both manufacturers and users need to work together to protect the IoT devices, applying proper IoT security standards and practices. Top Common IoT Security Risks As IoT (Internet of Things) devices continue to grow in popularity in both homes and businesses across India, it’s essential to know the risks involved. The intelligent devices in the IoT space can make life much easier, but they come with security risks. Let’s take a look at the most prevalent risks related to IoT security. 1. Weak Passwords and Login Security The majority of IoT devices come with easily guessed default usernames and passwords. The majority of users forget to change these default names and/or passwords and thereby leave themselves vulnerable to hackers. Other devices do not request a password. This very low level of authentication makes for an easy attack vector to exploit the access and maliciously use the target IoT device. 2. No Regular Software Updates Many IoT devices get infrequent (if any) updates for either the software or firmware. Older security issues are going to remain fixed, and hackers are going to use known bugs to exploit your device. Regularly updated devices are certainly going to be safer, but not all manufacturers provide those updates. This increases the demand for regular IoT security audit practices. 3. Low Processing Power The CPU power and storage of an IoT device are small in comparison to a normal computer. Due to the limited memory and CPU power, it is not viable to implement a strong security tool, such as an antivirus or a firewall. IoT devices are left vulnerable to cybercrimes, where the cybercriminal can generally breach the basic protection level. 4. Unencrypted Data Transfer Some IoT devices send and receive both information and data in the clear, unencrypted. This means an attacker on that network has access to anything sent to/from that device, so your sensitive information, such as your passwords, health data, and location data, is at risk. If this information is broadcast without encryption, then it becomes very easy for them to capture it and utilise that data inappropriately. 5. Using the Same Network for All Devices Some users connect their IoT devices to the same wi-fi as devices such as laptops or mobile phones. If an IoT device is hacked, then the attacker can access other connected systems. This makes all aspects of this network unsafe and increases the possibility of data theft. Read our recent suggested blog on IoT Device Security. Latest Penetration Testing Report Download How to Mitigate IoT Security Risks Securing your IoT devices from hackers is important. It’s not difficult to protect your IoT devices and personal data, and there are a few easy steps you can take to secure your devices. By taking a few common-sense steps, you can minimise your risks and enjoy smart technology and its benefits. The following outlines some essential ways to secure your IoT devices. 1. Create Strong and Unique Passwords When you first set up any IoT device, change the default password. Ensure you are using strong and unique passwords that are not easily guessed. Avoid using common passwords like “123456” or “admin”. When available, two-factor authentication adds another layer of safety. It is a simple way to deter easy break-ins. 2. Ensure Firmware is Current IoT devices often have updates to address security bugs. Be sure always to keep the device firmware up-to-date. Enable automatic updates, if available, so you do not have to update manually. In this way, your device will continue to be protected against existing threats. This is a common step in any IoT security audit or IoT device penetration testing. 3. Encrypt Data Transfers Be sure that all data that the device sends or receives is encrypted. Encryption will help protect the data from any hacker intrusion. Use secure protocols and file transfers, such as TLS and HTTPS. As a bonus, using a VPN will protect the device’s security during communication and protect data. 4. Use Private Networks Never connect your IoT devices via public Wi-Fi. Use your secure home network, set up a private network, or connect through a trusted VPN provider. Public networks are open and unsafe from hackers and malware. A private network provides more control and protection for your data is a basic part of IoT security testing. 5. Monitor Device Behaviour Pay attention to your device’s behaviour. If you notice unusual spikes in data use or failed login attempts, it may indicate a problem. There are many tools to help identify unusual activity early, which allows you to react before a bigger issue occurs. 6. Disable Unused Features Turn off all features you do not use, e.g. voice calling, SMS, or incoming data. Fewer features will reduce points of attack for a hacker and also save

Securing IoT Devices: A Penetration Tester’s Challenge

[email protected] / January 5, 2024

As everyday products become “smarter,” our digital footprints grow larger. Each of these internet-enabled gadgets, from watches to vehicles, serves as a data-transferring endpoint in a device known as the Internet of Things ( IOT ) . However, this advancement has created previously unheard-of issues in protecting the security and privacy of those associated devices. Strong protection capabilities are necessary as IoT becomes more embedded into our homes, workplaces, and public infrastructure. This blog will demonstrate IoT device Penetration testing , its benefits, risks, and what challenges testers face. Why is IoT Device Security So Important Today? As the influence of IoT devices grows, so does the possibility of illegal network access. IoT devices were not created with any security safeguards in place by design. Installing security software after the event is usually out of the question. Image Furthermore, a high level of security supervision jeopardizes public safety and economic stability. IoT devices security frequently hold sensitive information, such as financial and personal information, which must be protected. Any security breach might reveal this data, resulting in negative effects such as identity theft and financial loss. Power grids, transportation devices, and healthcare all rely on Internet of Things devices. Unauthorized access to these devices can have serious consequences, such as power outages, transit delays, and possible loss of life. IoT devices are frequently connected to company networks, allowing attackers to infiltrate and hack corporate networks. Furthermore, a successful attack can result in data breaches, intellectual property theft, and other repercussions. When discussing the Internet of Things cyber security, the need for physical boundaries, badly designed devices, non-standard gadget makers, and inadequate QC & QA (Quality Assurance and Quality Control) present a strong argument. Two key scenarios demonstrate the necessity for IoT security solutions: Securing a network’s operation and digital perimeter Data security IoT Device Pentesting: An Overview Penetration testing (also known as pentesting) simulates a cyberattack to assess the security of a computer device or network. Penetration testing seeks to identify security weaknesses and vulnerabilities so that they may be fixed or minimized before hostile actors exploit them. IoT device penetration testing is the act of evaluating Internet of Things devices and networks for vulnerabilities. This includes the IoT device’s security as well as the communications it transmits and receives. The Objective of IoT Device Penetration Testing IoT Device penetration testing is critical to a robust, all-encompassing IT security program for an organization’s devices and networks. It seeks to detect and resolve flaws in an organization’s IoT security posture that might allow attackers to steal sensitive data or gain unauthorized access to an IoT device or network. Furthermore, IoT pen testers assist in enhancing the security and resilience of their devices by addressing these weaknesses, reducing the likelihood of intrusions dramatically.

However, there is more to learn about the advantages of pentesting in IoT devices of this testing approach, which is why we’ve compiled a list of the top 3 reasons why penetration testing should be a part of every IT infrastructure: 1. Enhance Your Security Posture The appealing aspect of pen testing is that there needs to be a method to conduct it. Several sorts of testing are available, and experts advocate combining multiple procedures to achieve the best findings. Indeed, the variety of penetration testing in IoT methodologies will keep your company’s data secure and strengthen its security posture. This is because different methodologies give varied findings, which, when combined, offer decision-makers a complete picture of the company’s weak points. 2. Determine Security Vulnerabilities Security flaws range from secret back doors to out-of-date software tools, so you need to know which ones impact your devices most. For example, if your organization employs IoT devices, the amount of risk may rise because these are among the most neglected networked devices in terms of cybersecurity. Fortunately, you can employ pen testing with hybrid security solutions to assess whether any of your users are participating in potentially dangerous or malicious conduct. 3. Regulation with Compliance Cybersecurity rules assist organizations in understanding various security requirements and advocating for a more secure corporate environment. Furthermore, several of these requirements require organizations to do frequent penetration testing of IoT devices and audit their IT devices to guarantee compliance. Failure to comply frequently results in a data breach, resulting in a fine, an inquiry into the company’s cybersecurity measures, and diminished consumer trust. “Read more: Why IoT Device Pentesting should be a part of your business security.

Today in our blog, we will discuss IoT device penetration testing. Before we go into the IoT Pentesting section, let’s see what IoT is and why it is a concern in the modern days of digitalization. “The Internet of Things (IoT) represents the network of physical objects—a.k.a.” devices “—that are equipped with sensors, software, and additional technologies to connect and exchange data with other devices and systems over the Internet.” According to estimates, there will be 55.7 billion IoT devices on the planet by the end of 2025. But is it a secure system? According to reports, the IoT security market reached 3.35 billion in 2022 and is predicted to increase at a CAGR of 26.36% to 13.36 billion by 2028. In the first half of 2022, malware assaults on IoT devices surged by 77%. Furthermore, there are numerous reasons why IoT companies are relying on securing their devices. Let’s check out the reasons and all about the security testing of IoT devices in our complete guide. We’ll shed light on the what and why of IoT testing, and the benefits, challenges and why should you as a business trust a service provider. Why are Businesses Worried About Securing IoT Devices? The Internet of Things penetration testing includes a wide range of linked devices inside a network, from smart household appliances to driverless vehicles. And, unlike in the past, when cybercriminals exclusively targeted computers or cellphones for personal or sensitive data, emerging IoT risks target anything that interacts with the internet. If a cybercriminal successfully hacks into a smart vehicle, for example, they may be able to disable security measures or driving capabilities. A cybercriminal who compromises medical equipment, such as a heart monitor, may be able to interrupt communication to and from the internet, causing the gadget to malfunction and endangering lives. The new world of IoT and linked devices has created a vast attack surface with an exponential growth in the number of access points for hackers. Furthermore, cyber-attacks on IoT devices are a real and serious concern. Cyber-attacks have the potential to damage how we use our gadgets to operate our homes, automobiles, and even how we bank. Without question, the Internet of Things is the technological future. However, as the popularity of IoT goods grows, so does the number of vulnerabilities discovered in such items. It is now more vital than ever to properly secure the Internet of Things to safeguard your sensitive data, appliances, and overall well-being. Here comes the role of IoT penetration in securing the device. Let’s see how and why. What is IoT Device Penetration Testing? IoT penetration testing is a thorough assessment method that replicates real-world cyberattacks on IoT devices and networks. Furthermore, this systematic approach entails many strategic measures, each of which contributes to a comprehensive review of the security landscape around these smart devices. IoT penetration testing is essentially a simulated assault on IoT systems, similar to a security exercise. Furthermore, the goal is to identify vulnerabilities and flaws that hackers may exploit, allowing companies and people to take proactive remedial steps. The relevance of IoT penetration testing cannot emphasize in a future where IoT devices are poised to outnumber people. Furthermore, cybercriminals are growing more adept, and unsecured IoT devices might become possible access points into larger networks. A successful hack might result in unauthorized access to sensitive data or possibly compromise safety-critical systems. IoT penetration testing encompasses entire ecosystems rather than individual devices. Every networked node, from smart homes to industrial facilities to connected cars, poses a risk. Thorough IoT device penetration testing assures these systems’ overall resiliency. Hardware, firmware, networks, wireless communications, mobile and online apps, and cloud APIs are all attack vectors in IoT devices.
