Digital Forensics Challenges

Enterprise Security Magazine | Wednesday, June 08, 2022

IoT Forensics is a swiftly growing subject within Digital Forensics. Because of the security challenges inherent in the IoT ecosystem, the demand for IoT forensics is growing daily.

The IoT (Internet of Things ) influences every aspect of life, from how people react to each other. The IoT's essential components are data-gathering devices. All of this is accomplished through the use of sensors.

The data received from all devices is transmitted to the cloud via a communication channel, such as cellular networks, WiFi, Bluetooth, or satellite networks.

Once the data attain the cloud, it begins to be analyzed. Data processing might be as plain as determining the footfall taken or as complicated as selecting an object in video footage based on the data gathered by the sensor.

The ultimate component is the user interface. All data gathered and evaluated must be made available to the end-user to act on it. Usually, this user interface is contained within a web browser or program.

Increased cybersecurity threats accompany the enormous growth of the IoT sector. Lately, cyber threat actors have drastically expanded their attack to match individuals' identities Privacy against IoT devices can assault, disrupt, and steal millions of users' data.

Therefore, digital forensic investigators are critical in the rapidly growing subject of IoT forensics. They can collect data from these sophisticated devices and create digital footprints that induce criminal suspects.

Digital Forensic Investigators have several obstacles in locating the relevant source, collecting and conserving artifacts, and processing massive amounts of data to uncover critical evidence.

Here are the primary obstacles to overcome;

Identification: Identifying possible proof in an IoT context might be challenging. Rather than a single host or data center, data is scattered across multiple cloud services, cryptocurrency wallets, network-attached storage units, and online social networks. As a result, digital forensics professionals meet significant problems when seeking evidence. Even if the location is fixed, investigators may be unfamiliar with the IoT devices and supporting infrastructure.

Moreover, the resources may be subject to different countries, each having its own set of challenging and sometimes unauthorized intrusion legislation and inconsistent data protection.

Acquiring and Preserving: When a capable source of evidence is found, the challenge becomes how to collect and preserve evidence from IoT devices, applications, IoT services, and IoT networks in a forensically sound manner. The main issue is the battery life of IoT devices. Most IoT devices have restricted processing and storage capabilities compared to laptops and smartphones.

Specific IoT devices may lack a persistent memory containing user data and may have limited power, significantly limiting the duration of the device or even precluding live forensics. In addition, data encryption can make evidence collection extremely hard.

Analysis: The analysis of acquired proof may be hindered by the medium it was received. At this phase of the inquiry, the main concern is the volume of data that an IoT device may cause.

The amount of evidence assembled in IoT is substantially more tremendous than traditional digital forensics. At this time, the issue of privacy is crucial. Collecting and analyzing evidence allows pieces of evidence to be pieced together and used to establish an individual's identity and conduct.

That is beneficial if the aim of the investigation is a component of the identification. Still, it is hard to predict in advance. The data gathered from an IoT system may contain information about people not participating in the research.
