Locating Data Traces
Maintaining data quality in evidence is essential for IoT forensics (Gómez et al., 2021). Extracting data involves working around the challenges of following a digital “footprint” through the various data collection and storage stages. This can be complex depending on the quality of the data.
IoT forensics experts have developed various automated methods to simplify the investigation process and make it more effective, resulting in clean, parsed, and structured data that can be used for investigative purposes.
1. Data Traces on Devices
This usually begins with uncovering information within the device itself, such as a smartphone. Unfortunately, many devices only store data for a short time. While most data leaves “traces” behind, these could be fragile and easily corrupted.
2. Data Traces in Networks
Networks used to transfer data may also maintain traces for a specific time. Again, these data traces are fragile and may disappear quickly. Moreover, different networks and processes will use varied encryption methods, creating additional hurdles.
3. Data Traces in the Cloud
Any data transferred from IoT devices that is then stored in or moved within the cloud will leave digital traces behind. Cloud service vendors and ethical hackers can often aid in cyber forensics by preserving and recovering such relics. Of course, they do so only when the recipient has the legal authority to make such a request.
Getting Trained for IoT Forensics
The digital forensics market is expected to more than double within a 5-year period (Markets and Markets, 2018). Considering the rapidly rising number of IoT devices and associated cyber risks, the field of IoT forensics is likely to expand as well.
You can make sure you’re prepared for the future by getting trained with EC-Council as a Computer Hacking Forensic Investigator (C|HFI). EC-Council’s certification programs prepare IT and cybersecurity professionals for today’s toughest challenges, including IoT forensics investigations.
