An essential guide to securing your Internet of Things devices
by Prashant Pujara
The time is here when, Internet of Things has become an important part of our lives, extending beyond just smartphones and computers. From the smart gadgets in our homes to the automated features in our cars, IoT is everywhere, collecting large amounts of data about our habits and interactions.
This interconnected network provides incredible convenience but also comes with a lot of security risks. To safeguard our devices, personal data, and networks from cyber threats, it's important to adopt effective security measures.
The primary focus is to start by securing individual devices and then ensuring the entire network is safe and well protected. Once a device is connected, we need to secure its internet connections and data storage while enforcing robust security policies.
In the following section, we'll learn more about the practical steps for enhancing IoT security, beginning with the development of a comprehensive security strategy.
Importance of IoT security.
Ensuring the security of IoT devices is more critical than ever. Our homes and workplaces are filled with interconnected gadgets, from smart thermostats to self-driving cars. It's essential to prioritize keeping our data and privacy safe in this tech-savvy world.
In the past, hackers mainly targeted computers and smartphones for sensitive information. But with the rise of IoT, their focus has shifted to any device connected to the internet. This means we need to be proactive in safeguarding our devices and networks against potential threats.
Consider a scenario where a cybercriminal gains access to a smart home security system. They could potentially disable the alarms or unlock doors remotely, putting the safety of the residents at risk. Similarly, if they breach a connected medical device like an insulin pump, they could tamper with dosage levels, endangering the health of the patient.
In today's connected world, if there's a breach in IoT security, it doesn't just affect our privacy. It can also put our safety at risk. That's why it's crucial to make sure IoT devices are secure, not only to protect our private information but also to keep us safe and give us peace of mind.
10 Best practices for securing IoT
When it comes to enhancing IoT security, there are several best practices you can implement.
1. Update firmware regularly
For any business or organization, it’s important to ensure that all your IoT devices have the latest firmware updates installed. These simple updates often include patches for known security vulnerabilities.
2. Use strong passwords
The best way is to set unique and complex passwords for each of your IoT devices to prevent unauthorized access. Also, avoid using default passwords, as they are often easy to guess for attackers. For example, the 2019 Ring camera hacks occurred due to users not changing default passwords.
3. Start enabling two-factor authentication (2FA)
Whenever possible, keep a practice to enable two-factor authentication for accessing IoT devices. This can add an extra layer of security by requiring a second form of verification. Here, a code will be sent to your phone. For instance, Google reported a 100% success rate in preventing account takeovers by enforcing 2FA for its employees.
4. Secure your IoT network
To keep your IoT devices safe from hackers, use strong Wi-Fi encryption like WPA3, which is like a secret code for your Wi-Fi. Also, set up firewalls, which act like guards protecting your devices from bad guys trying to get in.
5. Segment your IoT network
Think of this as organizing different rooms in your house for different purposes. Moreover, creating separate network segments for your IoT devices and sensitive data, it's like putting them in different rooms with their own locks. This way, if there's ever a security issue in one area, it won't affect the others, keeping your important information safe.
6. Start monitoring your device activity
It's important to keep an eye on your IoT devices. Also, regularly checking their activity for anything unusual, like strange behavior or attempts by unauthorized users to get in, helps keep everything safe and running smoothly.
7. Disable all unused features
Turn off all your unnecessary features or services on IoT devices, this will help to reduce the attack surface and minimize potential security risks.
8. Take regular security audits
The best practice is to conduct regular security audits of your IoT ecosystem to identify and address any vulnerabilities or weaknesses.
9. Start implementing access controls
Limit access to IoT devices to only those who need it, and regularly review and update access permissions as needed.
10. Spread users awareness
Studies reveal that 95% of cybersecurity breaches are caused by human error. For example, raising awareness about phishing attacks can empower users to identify and avoid potential threats. Offer training and awareness programs for users to help them understand the importance of IoT security and how to respond to potential threats.
In conclusion, protecting your Internet of Things devices is essential in today's digital time. By following the above best practices, you can enhance your security and enjoy the benefits of IoT with confidence. Stay safe and keep your IoT devices secure.
