In this era of digitalization, technology is considered to be one of the most convenient & important ways to communicate between individuals in a sophisticated way. Internet of Things(IoT) has truly emerged extensively in the world of technology that an ordinary device is made uniquely identifiable, contactable and addressable with the help of internet service. Besides making the human manual chores easy, the IoT is prone to massive data breaches and cybersecurity threats that increase the need of digital forensics in IoT world.

From the Amazon Echo to the smart smoke detectors, we have incorporated IoT devices in our day-to-day life that can ease the work truly to a great extent. However, all of these home automation appliances, connected physical devices, etc are the part of IoT. Therefore, in this blog, we will describe the importance of computer forensics & IoT forensics challenges in a precise way.

Overview of Internet of Things (IoT)

The ultimate goal of the Internet of Things is to make the lives of the users more convenient and dynamic. Additionally, IoT devices help to exchange information between themselves to develop an innovative environment to the end user that makes it a remarkable one. IoT technology has emerged in different arenas such as medical care, social domains, smart home, smart city, etc. At the same time, it also provides more opportunities with regards to cybercrimes attack that will directly impact the users. This leads to an increase in need of digital forensics with respect to the increase in the importance of IoT. One of the downsides of the devices, which is been developed with IoT technology is that is not designed with security in mind, as the major concern was to minimize the cost and size. As a result, these devices have a deficiency in hardware resources. This one of the reason that increase the significance of computer forensic IoT environment.

In order to analyze the device for a forensic purpose, each IoT device allows to provide important artifacts to begin the investigation process. However, the standard forensic workflow comprises of identification, interpretation, preservation, presentation and analysis. Similar such workflow is integrated for IoT devices for the purpose of forensic investigation. To know more about the role of computer forensics in the digital forensic investigation process go through the bellow section.


Let’s Dig in a Little Deeper About Importance of Computer Forensics in IoT World!

Altogether, IoT technology is a combination of various technology zones that includes IoT zone, Network zone and Cloud zone. Moreover, all these zones can be a source in collecting the IoT digital shreds of evidence. Whenever there is a need of digital forensics investigation one can collect the evidence from a smart IoT device or a sensor, from an internal network like firewall or router or from the outside networks such as cloud or any similar application. Now, based on these zones, IoT consists of three aspects with regards to forensics, which includes cloud forensics, network forensics & device level forensics.

While talking about Cloud forensics, most of the IoT devices are capable enough to connect with the Internet to share the resources in the cloud via applications. Hence, these sensitive data, which is stored in the cloud becomes the target for hackers or attackers. Moreover, an examiner has to face a tough time to collect the evidence as they have got limited control and access to seize the digital equipment.

In the case of Network forensics, all the different types of networks that the IoT device is used to send and receive the data is included. For instance, suppose if an incident happens in an IoT device, all the logs from which the traffic flow has passed through could be a piece of potential evidence like firewall or IDS logs.

When it comes to Device forensics, one can seamlessly collect all the possible digital evidence from the IoT devices such as graphics, audio, video, etc. For example, all the potential graphics and videos from the CCTV camera or it can be audio from the Amazon Echo device is one of the best examples in the case of device level forensics.

What Could be the Possible IoT Forensics Challenges?

In this, we are going to discuss about some of the major IoT challenges that causes difficulties and issues in the investigation process. Due to the need of digital forensics is increasing day by day these are the some common situations that all should know to perform proper investigation in the IoT world.

  • Data Location: This is one of the foremost challenges that the forensic investigator faces to collect the data that is been dispersed in different locations. Additionally, IoT data cloud can be located in different countries and also may be assorted with the information of other users.
  • Finding Accurate Cloud-based Accounts: Most of the accounts in the cloud service is anonymous. This is because it does not require proper details to use the cloud service. Even though the need of digital forensics investigation is increasing rapidly, but if an investigator navigates the evidence from the cloud during the investigation, which is related to an IoT device to examine the crime scene, it does not depict as a proven source to identify the criminal.
  • IoT Security Challenge: Due to lack of security in the IoT technology, the evidence collected from an IoT device can be deleted or changed. Hence, these evidences are not solid enough that the law court can easily accept the same.
  • Identifying the Device Type: At times, a digital forensic investigator has to undergo a tough time to identify the type of device used in the digital crime scene. This makes the process of acquiring the evidence quite complex to process the forensic examination.
  • Maintenance of Data Format: Often times, the format of the data, which is generated by the IoT device is not matched with the data that is saved in the cloud. Moreover, the user has no direct access to his/her data and also the file which is stored in different file format. After all, the data must be retained in the original format to present in the court before performing the analysis process.

Well, now you all know the importance of computer forensics and the IoT forensics challenges faced by the investigators during the process of investigation. But now you all start to think the best way to perform the investigation in IoT environment.

Get the Best Approach to Perform Digital Forensics in IoT Environment!

We already discuss the need of digital forensics in IoT environment Well, most of the existing tool does not pose a proven technology to fit with the heterogeneous infrastructures of the IoT world. When a hacker can easily monopolize the collected evidence from the IoT devices, just because of the weakness exhibited by the IoT devices while considering the security factors. Thus, there is no point to extract such evidence from the devices as the data collected is not been accepted by the law court. This means, With the increase in significance of computer forensics, without having a proper forensic software a digital forensic examiner has to face to a tough time in collecting the evidence from different mediums. In order to collect the evidence from different computer application that are involved in the criminal scenes, simply make the best use of MailXaminer tool. This is the most recommended utility which is developed by the best technocrats that enables a user to easily locate and collect the evidence in a simplified way from different computer applications.

Concluding Lines

Due to the existing security challenges in the IoT devices the need of digital forensics is increasing day by day manner. No doubt, the forensic experts need to face multiple challenges to analyze and examine the IoT devices for the purpose of forensic analysis. With the various forensic limitations exposed by the IoT devices, a forensic expert need to play smart enough to examine the data. However, with the help of the aforesaid tool, which is the most unique and full-fledged tool that allows one can smoothly investigate all IoT related crimes in a hassle-free way.
