Internet of Things (IoT) is the inter-connection of the smart devices such as smart TV, mobile phones, cars, production plants machines, jet engines, oil drills, wearable devices, smart toys and more smart devices. The connected devices are responsible for sharing information, data, messages, videos, audios and storing data. The Internet of Things (IoT) is increasingly growing. In 2020 up to 50 billion devices will be connected to the internet, according to a researcher. In Internet of Things (IoT) devices are connected together in a smart and efficient way. Use of the broadband connection is increasing due to its low cost so that various devices such as laptop, mobile phones, smart TV are connected with Wi-Fi capabilities.
The devices such as smartphones, coffee makers, washing machines, headphones, lamps devices store sensitive data. The Internet of Things (IoT) device becomes vulnerable due to the loopholes present in the device. An attacker targets these IoT devices to steal sensitive data and to launch Distributed denial of service attack. IoT devices are targeted by some malware; one of the most popular is Mirai botnet. Mirai botnet targeted millions of devices to launch distributed denial of service attack. Mirai is a malware that primarily targets online consumer devices such as remote cameras, home routers, smart TV, smart car, smart phone and other IoT devices.
Mr. Sandro Gaycken, head of the digital society institute at the Europeans School of Management and Technology said that IoT has very poor security concepts and the criminal will pick this up. The Internet of Things (IoT) attacks are increasing due to lack of security.
Why are IoT devices compromised?
The IoT devices are compromised due to following reasons:
- Running vulnerable application
- Outdated software
- Insecure web interface
- Default credentials(Username/password)
- Insufficient Authentication and Authorization
- Insecure Network Services
- Lack of Transport Encryption
- Privacy Concerns
- Insecure Cloud Interface
- Insecure Mobile Interface
- Insufficient Security Configuration
- Insecure Software and outdated Firmware
- Lack of Physical Security
How to protect your IoT devices?
There are some basic practices that should be followed by everyone, from individual consumers to the largest global enterprises:
- Regularly checking for and installing software updates
- Implementing appropriate security software
- Making sure that the default username and password are changed
- Making sure that all your devices are up-to-date with all the latest security and firmware updates
- Using encryption methods for your data
- Setting up your own ‘private’ network for your network devices
- Downloading and installing application and software from trustworthy sources
- Avoid connecting to free Wi-Fi
- Using strong encryption methods to your home wireless devices
- Protecting your device with password
- Checking for “Universal Plug and Play” features and turn these off
- Being aware of social engineering and phishing
- Avoiding opening spam links on your smart devices
