IoT Forensics plays a significant role as a result of existing security threats. Although it consists of some serious challenges, but still, by using it, experts can efficiently investigate all IoT-related crimes.
FREMONT, CA: IoT forensics involves analyzing IoT devices to investigate crimes. In investigating cybercrimes or examining the source of a security breach, organizations or law enforcement may hire experts to gather and preserve data.
Malicious intent can sometimes lead to breaches. Another possibility is that they may be the result of a human error, such as an employee sharing sensitive information as a result of a phishing attack. Although an employee may not have intended to steal data or harm the company, sharing that data can have catastrophic consequences. Nearly nine out of ten data breaches are caused by phishing attacks.
As well as determining the exact intent and extent of a breach, cyber forensics can provide a number of other benefits. Cyberthreats associated with IoT include:
• Ransomware is one type of malware
• Attacks using botnets and distributed denial-of-service (DDoS)
• Theft of data
Cybercrime investigation is not the only purpose of IoT forensics. On-site crimes such as burglaries can produce data on various devices that can be used to assist in the investigation. IoT forensics and digital forensics differ depending on whether the device is smart or not, which brings us to the difference between them.
The difference between IoT forensics and digital forensics are:
A digital forensics investigation deals with digital evidence, while IoT forensics focuses on internet-connected devices.
The internet provides a number of unfortunate opportunities for data corruption or misplacement, but it also ensures that most data is readily available for legal review by an expert. Digital evidence is found using a variety of methods by IoT forensics experts.
IoT Forensics challenges are listed below:
When data is heavily encrypted, decryption may be difficult, for example, if the decryption token is lost or corrupted or if the encryption method is unusual or error-prone. The data is often corrupted during transfer or when vendors store it for longer periods of time.
Many companies have policies for preserving data for a specified period of time. However, providers also protect data from access unless someone can prove a legal right to access it. Data forensics require legal action and many special permissions that may be difficult to obtain, depending on the storage provider's policies.
IoT cyber forensics investigations face the following challenges:
• Data standardization across vendors is lacking
• Decryption difficulty
• Corruption of data
• Laws relating to data protection and privacy
For IoT forensics, maintaining data quality is essential. In order to extract data, it is necessary to follow a digital footprint through the various stages of data collection and storage. Depending on the quality of the data, this can be a complex process.
Experts in IoT forensics have developed automated methods for simplifying the investigation process and making it more effective, resulting in structured, parsed, and clean data that can be used for investigation.
