Digital Forensic

Digital forensics is the process of collecting, preserving, analyzing, and presenting digital evidence in a way that is admissible in a court of law. It involves using specialized tools and techniques to investigate computer systems, networks, and other digital devices to uncover evidence of criminal activity, such as cybercrime, intellectual property theft, and fraud.

Here is an example of how digital forensics might be implemented in practice:

• Incident response: An organization’s incident response team receives a report of a data breach and suspects that an attacker has gained unauthorized access to the organization’s network.

• Identification: The incident response team isolates the affected system and identifies the user account that was used to gain access.

• Collection: The team collects evidence from the affected system, including log files, network traffic, and system images.

• Preservation: The team preserves the evidence by creating a forensic image of the affected system and storing it in a secure location.

• Analysis: The forensic team analyzes the collected evidence to determine how the attacker gained access to the network and what data was compromised.

• Presentation: The forensic team presents their findings to the incident response team and the organization’s management, along with recommendations for improving the organization’s security posture.

• Follow-up: The organization implements the recommended security improvements and takes steps to prevent similar incidents in the future.

In this example, digital forensics was used to investigate a data breach and identify the root cause of the incident. By collecting and analyzing digital evidence, the forensic team was able to determine how the attacker gained access to the network and what data was compromised. This allowed the organization to take steps to prevent similar incidents in the future and improve its overall security posture.
