Computer Forensics is identifying, preserving, extracting, and analyzing digital evidence from computers, mobile devices, and other digital storage media to investigate and prevent cybercrime. The main objective of computer forensics is to establish a clear chain of custody for digital evidence and to use it to uncover the facts surrounding a computer-related crime or incident. The major aspects of computer forensics include identifying, preserving, analyzing, and reporting digital evidence, along with using specialized tools and techniques to uncover the evidence systematically. As digital systems and technologies become an everyday part of our lives, computer forensics is becoming increasingly essential, as the volume and complexity of digital evidence make it more challenging to assess the authenticity, integrity, and accuracy of the data. This essay will examine the major aspects of computer forensics and how they are applied in practice.
As a cutting-edge Cybersecurity company, we can provide a detailed step-by-step forensic investigation process from the technical, business, and legal aspects and highlight the added value that makes Securesee special in providing that service.
Technical Steps:
The technical process starts with identifying the evidence relevant to the investigation. This can include seized digital equipment, documents, and other physical evidence.
The proper preservation of the evidence is crucial for forensic investigation as it ensures that the digital evidence is not tampered with or altered in any way. The forensic expert will perform a forensics acquisition of the data and create an imaged copy of the data or electronic device under investigation.
The third step is analyzing the digital data to extract relevant evidence. This analysis can be done using various software tools such as forensic suites, data recovery tools, and data analysis tools. Digital data that can be analyzed include deleted files, email messages, a person’s network connections, GPS location, and internet activities.
After analyzing the digital data, the forensic expert can report their findings. The report can include summaries of the analysis involved, the expert’s opinion, and any other relevant information.
Business Steps:
The business process includes briefing clients on the forensic investigation and services provided. This will cover a detailed explanation of expectations and deliverables.
Legal preparation involves consulting with the client’s legal team to confirm the nature of the data, confirm the context of the data and get legal advice on handling any sensitive data or evidence.
On top of preparing the report, experts have a feedback meeting or presentation about the investigation’s results for the client.
Legal Steps:
Forensic experts document the entire investigation, including what was collected, where it came from, the data sources, and procedures used for collecting and processing the evidence.
A forensic expert needs to follow the chain of custody and maintain the integrity of the evidence. The chain of custody is how proof is managed and handled, involving identifying, collecting, registering, and storing the proof.
Experts must act within the legal guidelines prescribed by the relevant jurisdiction. This may include legal regulations or industry standards.
