IoT security best practices

IoT Security or Internet of Things Security is a cybersecurity practice to protect IoT devices and their networks from cyber threats. Some commonly used IoT devices include smart home devices, smart watches, smart door locks, networked security cameras, autonomous connected cars, voice control devices, smart healthcare devices, etc.   Since IoT devices store and transfer data over the internet, IoT security is needed to help prevent data breaches. IoT devices have no built-in security, which is why companies need to give extra priority to their security. In 2022, over 112 million attacks were reported on IoT devices. Along with understanding IoT security, it is essential to know the many challenges enterprises face while dealing with IoT security issues. This blog covers all the important aspects of IoT security, so stay till the end.   What is IoT Security? IoT security is basically the strategies and procedures to defend IoT devices and the vulnerable networks they are linked with. Its main goal is to keep the user data safe, prevent cyberattacks, and keep the device running smoothly. Common IoT security practices include: IoT penetration testing Network security Data encryption protocols Strong authentication mechanisms Anything that is connected to the internet is prone to cyberattacks. Hackers use a variety of methods to compromise IoT devices. Once they are successful, they can steal confidential data or attempt to compromise the rest of the connected network and devices. IoT devices are slowly becoming a part of our everyday lives, and both consumers and makers may face a lot of IoT security challenges. IoT is very broad and as technology evolves, it is going to be broader. From watches and video game consoles to crucial business equipment, nearly every field is using (or going to use) IoT devices. This is both exciting and threatening, given the chances of cyberattacks. As a result, it is of utmost necessity to prioritize IoT security. IoT Security Challenges and Issues   As said earlier, IoT devices are not made with security in mind. As a result, there are a myriad of IoT security challenges that can lead to disastrous situations. Unlike many other technology solutions, few rules and standards are in place to direct IoT security. Additionally, most people do not understand the inherent risks associated with IoT devices, nor do they have any idea of these security challenges. Among the many IoT security challenges and issues, here are twelve crucial ones: 1. Lack of Visibility Users often deploy IoT devices without the knowledge of IT departments. This makes it impossible to maintain an accurate inventory of the devices that need protection and monitoring. Without a clear understanding of what devices are connected to the network, it becomes difficult to implement comprehensive security measures. 2. Limited Security Integration Due to the vast variety and scale of IoT devices, integrating them into existing security systems is challenging and sometimes impossible. Each device might require different security protocols and standards, making it hard to create a unified security strategy. 3. Broken Authentication Weak or broken authentication methods are common in IoT devices. This allows unauthorized users to gain access to sensitive data. Strong authentication mechanisms are necessary to verify the identity of users and protect the devices from unauthorized access. 4. Open-Source Code Vulnerabilities Firmware developed for IoT devices usually includes open-source software, which is prone to bugs and vulnerabilities. These vulnerabilities can be exploited by attackers if they are not identified and patched timely, putting the entire network at risk. 5. Lack of Standardization Lack of standardization means the absence of certain specifications and protocols that are agreed upon. This can result in different product systems or devices that are not compatible with each other. In IoT devices, it can cause difficulties in communication and data exchange between multiple devices. 6. Overwhelming Data Volume The massive amount of data generated by IoT devices complicates data oversight, management, and protection. Handling this data requires robust systems that are capable of processing and securing large volumes of information efficiently. You Might Like: Top Cloud Security Challenges 7. Poor Testing and Developing Because most IoT developers do not prioritize security, they fail to perform effective vulnerability testing. As a result, potential weaknesses in IoT systems remain undiscovered, leaving them exposed to cyber threats. 8. Unpatched Vulnerabilities Many IoT devices have unpatched vulnerabilities due to various reasons, including the unavailability of patches and difficulties in accessing and installing them. These unpatched flaws can be exploited by cybercriminals, leading to security breaches. 9. Vulnerable APIs APIs are often used as entry points for cyberattacks, such as SQL injection, distributed denial of service (DDoS), and network breaches. Weak API security can provide attackers with control over IoT devices and access to sensitive data. 10. Weak Passwords IoT devices are usually shipped with default passwords that many users fail to change, providing easy access for cybercriminals. Additionally, users often create weak passwords that can be easily guessed, further compromising device security. 11. Lack of Encryption While encryption is a major security practice, it can also be a challenge. Many IoT devices do not use encryption to protect data during transmission, making it easier for attackers to intercept and exploit sensitive information. Encryption is essential for ensuring data privacy and security. 12. Insufficient Network Security IoT devices often connect to networks without proper security measures, making the entire network vulnerable to attacks. Implementing robust network security is crucial to protect connected devices and the data they handle. Types of IoT Security IoT security solutions can be implemented by both the users and makers. There are basically three types of IoT security, such as: 1. Network Security Users should protect their devices against unauthorized access and potential exploitation. Therefore, IoT network security implements a zero-trust security strategy to minimize the corporate attack surface. This approach assumes no device or user is trusted by default and requires continuous verification of all connections and activities. 2. Embedded Nano agents provide on-device security for IoT systems. These agents offer lightweight, yet
