Common Threats to Security and Privacy of IoT Devices

Common Threats to Security and Privacy of IoT Devices:

IoT (Internet of Things) refers to a system in which millions of devices across the world are connected to the internet and are able to collect and share data over wireless network without involving human intervention.

Today, internet is growing at a very fast speed with new advancements in technology. Previously, we did not require any advance security system for our wireless devices and networking equipment because in that era internet was not as advanced as today. Now in the new age of advanced technologies, attacks on internet connected devices are rising exponentially. So, security and privacy of internet devices are becoming important now.

Some common security and privacy threats of IoT device:

Weak Passwords / Credentials:
Generally, internet enabled devices and networking equipments come with a default username and password and some users do not change them until security experts suggest them to do so. In this scenario, hackers get golden chance to hack or control the user’s device and intervene in the user’s privacy.

Complex Structure of IoT Devices:
IoT devices can have very complex structures and it’s very difficult for users to detect them. Sometime owners are unaware of the fact that their device has been hacked. Hackers can join device to any malicious botnet or infect it with different kinds of malwares.

Outdated Hardware and Software:
IoT devices are manufactured with latest hardware and software but issues prop when it does not get regular updates after manufacturing. We know that internet technologies are growing extremely fast. So after few months or years, it becomes relatively easy for hackers to hack old devices with the latest tools and technologies.

Increase in Malware / Ransomware:
The threats of malicious softwares and ransomware has rose sharply in the last few years. These malwares are become big challenge for IoT companies in securing their devices.

Insecure Data Transmission:
Large amount of IoT devices are connected to networks and it is very hard to transmit all the data securely. There is always a chance of data leak or data corruption or device getting infected by malwares.

Small Scale Attacks:
Manufacturing companies always try to secure their devices for large scale attacks but it is difficult for them to secure the device for each and every small attack possible. Hacker gain opportunity at this point and try to execute smaller attacks on monitoring devices, open wireless networks etc. and thus try to infect the network with malwares.

Smart Devices:
Sensors are the most important part of any smart device. It enables them to communicate with other sensors or networks within its infrastructure. But these sensors are unaware about other sensor’s network status. Hackers can hack these IoT devices in the open wireless networks.

But this does not mean we should not use IoT devices, rather we should take some precautions while using it to reduce such threats:

  • Access them on your own network
  • Always update software patches
  • Use strong and unique passwords for all the IoT devices and accounts
  • Use separate network for smart devices
  • Configure device setting at high level
  • Install firewall
  • Use strong encryption
  • Disable unwanted device features
