While cloud-based security focuses on protecting data that is stored in the cloud, Internet of Things security measures are designed to protect the physical network of devices that are connected to one another in a given place. Securing IoT devices is required whether you are establishing a home network or a complex network in an industrial complex, so it’s essential to take the correct measures.
The Importance of IoT Security
The Internet of Things, or IoT, refers to a set of physical devices that are connected through a common internet system. For example, in modern households, there may be an IoT that connects the thermostat, the garage door opener, smart appliances, gaming consoles, and the mobile devices everyone in the household uses. According to TechTarget, securing IoT devices is crucial because each device within the network is vulnerable to a cyberattack, and all devices are holding valuable data that could be used by hackers for their personal gain.
The Role of IoT in Today’s Digital Age
The role of IoT continues to become more prominent with each passing day, as more devices are created that are designed to be connected to the internet. Advanced and complex IoT networks will continue to be built, not only within an individual’s household but also in all places of business and learning, highlighting the critical importance of IoT device security.
The Intersection of IoT and Cybersecurity
By being aware of Internet of Things security risks and knowing how to secure IoT devices, individuals and professionals can work to protect themselves and their organizations. Cybersecurity professionals often have the most advanced knowledge and skills, allowing them to effectively implement IoT security measures.
Risks and Challenges Associated With IoT Devices
IoT devices are becoming increasingly common, with more and more devices offering internet connectivity and advanced, smart features. Knowing the risks and challenges associated with IoT devices can help you proactively address the security risks.
The Vulnerability of IoT Devices to Cyberattacks
According to Balbix, most IoT devices are built with convenience in mind — not necessarily security. These are a few of the reasons why IoT devices may be vulnerable to cyberattacks:
- Coding vulnerabilities – Some IoT devices have open codes that leave them at risk of attack.
- Minimal visibility – Oftentimes, individuals bring IoT devices into a network without identifying them, which can compromise the integrity of the device and the security of the entire network.
- High data volume – When the IoT network is overwhelmed with data, it may not function as well and may be vulnerable to attack.
- Weak passwords – Many people keep the default passwords in place for their new IoT device, and these weak passwords are easy for hackers to figure out, allowing them to easily access the device and the network.
Privacy Issues in IoT
Most IoT devices are designed to gather and store data, but this can lead to privacy issues, particularly if IoT security standards have not been put in place. According to Kaspersky, some IoT devices are designed in order to share and sell data, which can lead to privacy concerns among users.
Comprehensive Analysis of IoT Security Breaches
IoT security breaches have occurred since the first IoT devices were created. For more than 30 years, experts have been analyzing these breaches and working to figure out how to implement better IoT security standards to protect individuals and organizations from these attacks.
Impact and Consequences of IoT Security Breaches
The impact of IoT security breaches can be quite far-reaching. According to TechTarget, some of the most notable IoT security breaches have led to:
- Failure of operational technology that has led to widespread shutdowns and outages at the industrial level.
- Unparalleled access to personal devices by hackers, such as being able to reach children through baby monitors in their nurseries.
- Malfunctions in vehicles in which hackers were able to control features of the car remotely while the driver was operating it.
The Need for Strengthening IoT Networks and Devices
Recognizing the serious impact that IoT network security breaches can have on individuals and organizations, it’s imperative for all cybersecurity professionals to begin strengthening IoT networks and implementing more rigorous IoT security standards.
Existing Weaknesses in IoT Security
Some existing IoT security weaknesses include:
