Risks Associated With IoT Devices

We have entered an era of smart devices where from washing machines, TV’s to refrigerators and AC’s everything is connected with the internet. As per reports by Cisco, the number of devices connected with the internet will exceed 50 billion by 2020. However, there are certain risks associated with IoT devices which every user must be aware of. Here we have listed some of them which demand user’s attention.

  • Security Risks

There are a number of loopholes associated with IoT security, which a hacker takes advantage of. Security attack can be categorized into network, physical, software and encryption attack, each of which has its own consequences.

  • Physical attacks target hardware of an IoT system and attackers physically harm the device to disrupt the services.
  • Network attack on the other hand aims at disrupting the network layer of the device. DDoS attack is an example of network attack.
  • Software attack is launched on the software with an intention to steal information & exploit the device.
  • Encryption attacks target the implementation of algorithm on which the device works.

So, the user must possess thorough knowledge of the types of security risks and attacks to take preventive measures well in advance.

  • Legal Risks

Legal issues related to product liability can arise. For example, if an autonomous car gets into an accident, who shall be held liable? Now this is a legal issue as it is difficult to figure out whether the owner, manufacturer, passenger or the person who coded the software is at fault.

  • Privacy Risks

Since a lot of factors influence data protection, there are a variety of privacy risks associated with IoT. The number of cyber-attacks is soaring high and this has become a serious issue as nowadays most devices are connected to internet making it easier for cyber criminals to steal the information. This information can be applied to infer certain results or to be sold in the dark market which might be used against the IoT device user.

  • Lack Of Authentication/ Authorization

A lot of vulnerabilities could lead to this issue. Lack of complex device password & two factor authentication, insecure credentials etc. are more like an open invitation to cyber criminals to hack the devices and disrupt the operations.

Other Risks

  • Insecure Cloud Interface
  • Complexity
  • Insecure Mobile Interface
  • Insecure Network Services

IoT devices now play a mainstream role in our lives, and have become a major part of our official & personal space. Thus, it is important to take a note of all the risks associated with IoT in order to understand the impact they can have on us. It is high time that we take necessary measures to mitigate the risks associated with IoT so that we can enjoy maximum benefits that technology offers us.

Considerations For Mitigating Risk In IoT Devices

March 28, 2016

With the exponential growth of Internet of Things (IoT) devices, the security risks associated with them have also increased manifold. Each device, including TVs, refrigerators, home automation systems, air conditioning units etc., which is connected to the internet has an in-built operating system, making it vulnerable to the prevalent online threats. This, ultimately, puts the end-users’ privacy and security at stake.

Here are some factors that must be considered to mitigate security risks in IoT devices:

Keep devices updated

Keep all the IoT devices and routers updated to the current versions of the software applications. This will provide protection against any minor security flaws in the software which may make the device vulnerable to a hacking attack.

Change default login credentials

You must create unique and difficult usernames as well as passwords for all your IoT devices. If you do not change the default login credentials, hackers can easily gain access to your personal internet network by breaching your IoT accounts. Make sure the password you create is complex enough to be cracked.

Limit the data you provide to the IoT service or device

Provide only a limited amount of information that is absolutely required for the IoT device to function efficiently. Avoid giving in sensitive personal information and if possible, enter a nickname instead of your full name. This will protect you against a potential identity theft.

Be careful when selling or purchasing used IoT devices

When you buy a used IoT device, it is quite possible that it has a malware or backdoor that can provide hackers an access to your internet connection. With this, they can infect your network, track your online activity and steal other important information. If you need to sell off your IoT device, make sure you restore it back to the factory settings to delete all the personal identifiable information (PII) stored in it.

Set up a different network for IoT devices

Some internet routers allow the users to create a separate network for different devices. You can make all your IoT and wireless devices operate on a network other than your home’s internet connection. Therefore, even if any of your devices are compromised, the hackers will not be able to access your entire network.

We, at Centex Technologies, can help to safeguard your IoT devices against common cyber security threats. For more information, you can call us at (855) 375 – 9654.
