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.

Virus Attacks Through Wireless Internet

August 17, 2011

The use of wireless internet technologies for surfing various web pages has been increasing for a long time due to the ease and convenience that it offers to users. People are no longer sticking to fixed broadband lines connected to a fixed operating system and are instead accessing the internet through portable devices like laptops, tablets, phones, etc. Many places these days we have wi-fi connections that can be accessed by procuring the requisite username and password from the owners either by paying a certain fee or even free of cost in some cases.

This kind of free access to the internet at public places is making web surfers more prone to virus attacks that may be made through the openness offered by wireless internet systems. Anyone in the vicinity who is able to receive the wi-fi signal can simply log on to the network especially if it is being offered free of cost. In such a network, there can be all kinds of security lapses that may put your system at the receiving end of virus attacks. There are some tips mentioned below to help you avoid such attacks or at least help reduce their incidence:

  • Before logging onto any kind of free internet at a public place, you should ensure that the network is protected by the required firewall and antivirus software so as to build a multi protected layer for your operating system. There should be a strong IT department taking care of such requirements. You should beware of connecting your laptop the internet in the vicinity without checking for security problems that the internet may have.
  • It is advisable not to access websites and fill in your username and password at sites that contain private information about you that if stolen, may pose a significant threat to you. You should refrain from opening bank related websites or shopping websites where you need to fill in credit card related information.
  • It is essential to have good antivirus software installed on your operating system to help ward off virus attacks. Although not completely fool proof, such software can help reduce the number of attacks that your system may be subjected to.
