Internet of Things (IoT) Security: Challenges & Best Practices

The Internet of Things, or IoT, is a network of interconnected computing devices that can collect and transmit data without human intervention over a wireless network. The internet of things (IoT) has matured from its early stages of incubation into a clearly defined set of use cases that deliver discernible benefits to a variety of market verticals, despite its youth as a discipline.

Today, IoT is used to solve real-world business problems in a variety of industries. Healthcare, smart cities, building management, utilities, transportation, and manufacturing are among the early adopters of this technology, attesting to its numerous advantages.

Sensors/devices that communicate with the cloud via a form of connectivity make up an IoT system. When data is sent to the cloud, software analyzes it and decides whether to take action, such as adjusting sensors/devices without user input or sending an alert.

The internet of things isn’t just about computers and smartphones; almost anything with an on/off switch can be connected to the internet and become a part of it. Because of the sheer number and variety of ‘things’ that make up the IoT, it contains a significant amount of user data. Cybercriminals have the ability to steal or hack all of this information. The more connected devices you have, the more chances cybercriminals have to compromise your security.

What Is IoT Security & Why Is it Important?

When it comes to the Internet of Things, there are specific security requirements. Individuals and personal computers are not interchangeable with networking devices. An IoT device, unlike a person, cannot simply enter a password to verify its identity. Similarly, our computer operating systems are updated on a regular basis, but IoT must function at all times.

Dependable infrastructure is essential, particularly for mission-critical applications. This reliability is provided by 3GPP technologies. Because the internet of things is rapidly expanding, end-to-end security is required.

From improving the safety of roads, cars, and homes to fundamentally improving the way we manufacture and consume products, IoT solutions provide valuable data and insights that will improve the way we work and live. Success depends on the integrity and confidentiality of IoT solutions and data, as well as the mitigation of cybersecurity risks.

Factors That Affect IoT Security

Reliable data 

Reliable data is required for data-driven decisions. Data is increasingly being used to make important business, safety, and health decisions. Data must be accurate in order to make the best decisions.

Type of devices

Different devices necessitate various solutions. Some devices are capability constrained, with very limited capabilities, and traditional security methods are ineffective for such devices.

End-to-end ecosystems security

Security of ecosystems from beginning to end. Device manufacturers, network providers, platform providers, app developers, and end-users must all work together for the Internet of Things to succeed. It is critical to ensure the ecosystem’s security from beginning to end.

IoT security breaches can have devastating consequences. This is due to the fact that the Internet of Things has an impact on both virtual and physical systems. Consider a smart car that is connected to the internet: cybercriminals could gain access to it and disable certain safety features. 

As the Internet of Things (IoT) becomes more common in the industry – hence the term IIoT, or Industrial Internet of Things – cyberattacks have the potential to unleash a slew of potentially disastrous consequences. 

Best Practices For IoT Security Management 

While the Internet of Things can provide new data and useful insights, it can also expose your company to new vulnerabilities. As a result, it’s critical that businesses think about the security implications of IoT deployments before proceeding.

The following are a few best practices for managing your IoT security:

  • Keep your device and software up to date

Check that the vendor provides updates when purchasing an IoT device and apply them as soon as they become available. IoT device security relies heavily on software updates. Hackers can more easily compromise devices that use out-of-date IoT software. You may receive automatic updates from your IoT device, or you may need to check the manufacturer’s website for them.

  • Use strong passwords for all devices and your Wi-Fi network

A strong password is long, at least 12 characters, but preferably more – and contains a variety of characters, including upper- and lower-case letters, symbols, and numbers. Avoid obvious things like sequential numbers (“1234”) or personal information that could be guessed by someone who knows you, like your date of birth or pet’s name. You can use a password manager to keep track of your login credentials.

  • Create a guest network

Consider creating a guest wireless network, also using WPA2 or later and protected with a strong password, if your router allows it. Friends and family may be using devices that have been compromised or infected with malware before using your network, so use this guest network for them. A guest network can help to improve the overall security of your home network.

  • Keep track of the available features of devices & turn off any that aren’t in use

Check your devices’ available features and turn off any that you don’t use to reduce the risk of an attack. Consider a smartwatch: its primary function is to display the time. Bluetooth, Near-Field Communication (NFC), and voice activation are all possibilities. 

If you don’t use these features, you’re giving an IoT hacker more ways to break into your device, with no added benefit to the user. The risk of cyberattacks is reduced by turning off these features.

  • Enable multi-factor authentication 

MFA is an authentication method that requires users to provide two or more verification methods in order to access an online account. 

Instead of simply requesting a username and password, multi-factor authentication goes a step further by requesting additional information, such as an additional one-time password sent to the user’s phone or email address by the website’s authentication servers. Use MFA if your smart devices have it.

Conclusion 

IoT security management requires a paradigm shift from reactive to proactive and automated. Because of the large number of devices that will be connected, security automation and enhanced security analytics capabilities are required.

To operate a trusted IoT service, businesses that provide IoT services strive to reduce cybersecurity risks by leveraging network security insights and acting quickly when threats are detected.
