The Internet of Things (IoT) is the networking of objects. It's comparable to a social network or email provider, but IoT links devices rather than people. According to Ericsson, 22 billion devices will be on the Internet of Things by the end of 2022.
Business Insider's experts expect the figure to grow to 30.9 billion by 2025. As IoT devices increase in number so is the attack surface of the cybersecurity vulnerabilities they present.
IoT devices are particularly vulnerable to network attacks such as data thefts, phishing attacks, spoofing and denial of service attacks (DDoS attacks). These can lead to other cyber security threats like ransomware attacks and serious data breaches that can take businesses a lot of money and effort to recover from.
In this blog, we discuss how to address vulnerabilities and protect your IoT devices and networks from cyber-attacks. We also look into some major attacks targeted at IoT devices and how you can start securing IoT devices to prevent such cybersecurity compromises.
Among the devices that can connect to the IoT are voice controllers, smart locks, smoke alarms, lighting systems, fitness trackers, integrated body implants, vehicles, and many other types of gadgets. To document and share IoT device configurations or security protocols, organisations often need to convert PDFs into accessible formats for team collaboration and client communication.
Despite the benefits and bright prospects of the Internet of Things, there are some unresolved security issues as well as legal network and device security regulations that need attention. As IoT implies connecting multiple devices and storing lots of data, the system's failure can cause very significant problems to computer networks and sensitive data.
Gadgets and objects having built-in sensors are connected to an Internet of Things platform, which combines data from many devices and analyzes it.
One of the simplest examples is the sensors used in stores. They can detect how long the customers spend in different parts of the room, to which products they return more often, and what's the most frequent customer route around the store.
This data may be used to identify trends, provide suggestions, and detect potential issues before they arise.
Despite the multiple opportunities that IoT opens to businesses, there are many factors that create security threats. For instance, with many open code sources, like Magento React, for example, the hackers are well aware of the code peculiarities. Here are some other threatening factors.
Use of Default Passwords: Most businesses deliver gadgets with default passwords and don't even advise you to change them. This often happens with security cameras, home routers, and light control systems, for instance. One of the most significant risks to IoT security is that default passwords are widely known, making it simple for thieves to compromise them.
Unsafe Communication: The messages sent over the network by IoT devices are often not encrypted, which creates IoT security issues. Using standards like Transport Layer Security (TLS) and transport encryption is the best way to guarantee a safe connection. Utilizing several networks to isolate devices also ensures secure and private communication, maintaining the confidentiality of data sent.
Personal Information Leaks: Skilled data thieves may do significant harm even by simply learning internet protocol (IP) addresses from unpatched IoT devices. These addresses can be used to determine a user's precise location and residential address. Many internet security professionals advise using a virtual private network (VPN) to hide your internet protocol address and protect the IoT connection.
Automation and AI: AI technologies are already in use on a global scale. But automation has a drawback: it only takes a single programming error or flawed algorithm to bring down the entire AI network and the infrastructure it was in charge of.
Automation and artificial intelligence are just pieces of code. So if cyber criminals gain access, they can take control of the automation and do anything they choose. Therefore, ensuring that the instruments are protected against such dangers and assaults is crucial.
For balance, it’s also worth pointing out that as well as posing a threat, automation has a part to play in protecting IoT devices and entire IT infrastructures from malicious actors. The rise of AI security is an illustration of the empowering aspect of this tech, so it is simply up to the users of IoT hardware to embrace the opportunities available.
Hackers have the power to launch assaults and enter thousands or millions of unprotected connected devices, destroying infrastructure, taking down networks, or accessing confidential data. Here are some of the most illustrative cyber attacks demonstrating IoT vulnerabilities:
If you’re a business that relies heavily on IoT devices, it is important to evaluate the safety of your information systems and the data being processed by these devices. Taking a rigorous and regimented approach to assessing vulnerabilities effectively will leave you in a stronger position, regardless of how your infrastructure of hardware and software is orchestrated, or its complexity. You need to consider effective security solutions that can protect your business from cyber attacks and ransomware attacks that could occur as a result of IoT security vulnerabilities.
Hiring a cybersecurity expert to advise and guide you is one of the best solutions if you’re concerned about IoT vulnerabilities. A flexible and cost-effective solution like Cyber Management Alliance’s Virtual Cyber Assistant service is ideal if you’re just starting on improving your cybersecurity maturity.
Our Virtual Cyber Assistants can help you protect against IoT vulnerabilities and malicious software in the following ways:
If the Internet of Things (IoT) gadgets lack adequate security, we can only speculate about how much valuable data hackers may take from them. According to Finances Online, 98% of IoT device traffic is unencrypted. It’s also stated that 83% of desktop devices have no support for threats to IoT devices.
With these figures in mind, it’s easy to assume that the IoT security risks and major attacks above are just the start. So it’s important to take good care of our IoT network security and undertake essential security measures, preferably under expert guidance.
