IoT Security 101: Tips For Safeguarding Your Smart Devices and Networks
In the recent years, the internet of things has grown so rapidly that the development of its security had to quickly set up. Securing your IoT devices and networks is crucial to protect your privacy and prevent potential cyber threats.
IoT Analytics, an insights firm specializing in IoT research, reported that IoT connections, such as smart home devices, connected cars and network industrial equipment exceeded traditional connected devices such as computers and laptops, for the first time in 2020, representing 54% of the 21.7 billion active connected devices. The firm estimates that by 2025, there will be more than 30 billion IoT connections, which equates to about four IoT devices per person on average.
You must be wondering what is IoT? Its significance in modern life? How to safeguard your devices and network? This blog has answers to all your questions.
Let’s proceed!
What Is IoT?
IoT, or the Internet of Things, refers to the network of interconnected physical devices, vehicles, buildings, and other objects embedded with sensors, software, and network connectivity that enables them to collect and exchange data. In essence, it allows everyday objects to become “smart” by enabling them to sense and communicate information with each other and with central systems or cloud platforms.
Significance of IoT In Modern Life
Data Collection and Analysis: Internet of things devices can collect vast amounts of data in real-time. This data can be analyzed to gain insights, make informed decisions, and improve various aspects of our lives, from healthcare to energy efficiency.
Automation and Efficiency: Internet of things devices enable automation by allowing devices to communicate and coordinate without human intervention. This leads to increased efficiency and reduced human effort in various industries, such as manufacturing, agriculture, and logistics.
Improved Convenience: It enhances convenience in daily life. Smart home devices, for instance, can control lights, thermostats, and appliances remotely, making homes more comfortable and energy-efficient.
Safety and Security: IoT-enabled devices enhance security through surveillance cameras, access control systems, and alarms. They also improve safety through wearable devices that detect falls or health emergencies.
Business Insights: Its data analytics provides businesses with valuable insights into customer behavior, helping them tailor products and services to meet customer needs more effectively.
Fundamental Tips to Safeguard Your Smart Devices and Networks
Change Default Passwords
Always change the default usernames and passwords of your devices. Many devices come with generic credentials, making them easy targets for attackers.
Use Strong, Unique Passwords
Create strong, complex passwords for your internet of things devices and networks. Use a combination of uppercase and lowercase letters, numbers, and special characters. Consider using a reputable password manager to generate and store passwords securely.
Enable Two-Factor Authentication (2FA)
If your devices support 2FA, enable it. This adds an extra layer of security by requiring a second form of verification in addition to a password.
Segment Your Network
Isolate your internet of things devices from your main network by setting up a separate VLAN (Virtual Local Area Network). This helps contain potential breaches and limits an attacker’s ability to move laterally within your network.
Network Monitoring
Utilize network monitoring tools or services to keep an eye on your network traffic. This can help you detect unusual or suspicious activity.
Secure Your Router
Ensure your Wi-Fi router is secure by changing its default login credentials and using strong encryption (WPA3 or WPA2) for your wireless network. Disable remote management unless necessary.
Firewall
Set up a firewall to filter incoming and outgoing traffic. Configure it to only allow necessary communication to and from your IoT devices.
Regularly Check Device Permissions
Review and update the permissions and access levels for each device. Limit permissions to only what is necessary for their intended function.
Secure Mobile Apps
If your IoT devices are controlled via mobile apps, ensure these apps are from trusted sources, and keep them updated. Be cautious about granting unnecessary permissions to these apps.
Regularly Audit Your Devices
Periodically review your devices and remove any that are no longer in use. Unpatched and unused devices can still pose security risks.
Physically Secure Devices
Keep physical access to your devices restricted. Ensure they are not easily accessible to unauthorized individuals.
IoT Security Standards
Look for devices that adhere to recognized security standards, such as the IoT Cybersecurity Improvement Act in the United States or similar international standards.
Regular Backups
Back up your IoT device configurations and settings regularly. In case of a security breach, you can restore your devices to a known, secure state.
Privacy Settings
Review and adjust privacy settings on your devices and apps to limit data collection and sharing.
Regularly Test Security
Conduct security assessments or penetration testing on your network and devices to identify vulnerabilities before attackers do.
Summing Up
In summary, IoT has a profound and growing impact on modern life, revolutionizing how we live and work. Its ability to connect and empower everyday objects with intelligence and connectivity is transforming industries, improving efficiency, and enhancing our quality of life in various ways. As technology continues to advance, the significance of internet of things in our daily lives is likely to increase further.
Securing devices and networks is an ongoing process. By following the above mentioned tips and staying vigilant, you can significantly reduce the risk of security breaches and protect your smart devices and data.
