Introduction to Digital Forensics

 

Digital forensic science is a branch of forensic science that focuses on the recovery and investigation of material found in digital devices related to cybercrime. 

What are the steps in the Digital Forensics process?

• Identification - In the forensic process, it is the initial stage. What evidence is present, where it is held, and how it is stored are all part of the identification process.

• Preservation - Data is segregated, safeguarded, and preserved during this phase. It includes restricting people from utilizing digital devices to prevent tampering with digital evidence.

• Collection - In this step, investigators piece together data fragments.

• Examination - Details specific tools and techniques that are utilized to discover and extract data from the evidence.

• Analysis - In this step, investigators develop conclusions based on the evidence uncovered. It may, however, take several iterations of investigation to substantiate a single crime scene.

• Presentation - The process of summarization and explanation of conclusions is completed in this step.

Types of Digital Forensics

• Forensics of Disk is the process of obtaining data from storage media by looking for active, updated, or deleted files.

• Forensics of Networks is a digital forensics sub-discipline. It is concerned with the monitoring and analysis of computer network traffic in order to gather vital information and legal evidence.

• Forensics of Wireless Communications - It's a network forensics section. Wireless forensics' major goal is to provide the tools needed to collect and analyze the data from wireless network traffic.

• Forensics of Databases is a subset of digital forensics that deals with the investigation and analysis of databases and their associated metadata.

• Forensics of Malware is responsible for detecting dangerous code, and evaluating its payload, viruses, and worms, among other things.

• Forensics of Emails is the process of recovering and analyzing emails, even those that have been deleted, calendars, and contacts.

• Forensics of Memory is the process of gathering data in raw form from system memory (system registers, cache, and RAM) and then carving it out of the raw dump.

• Forensics of Mobiles is a branch of forensic science that focuses on the investigation and analysis of mobile devices. It allows you to retrieve phone and SIM contacts, call records, incoming and outgoing SMS/MMS, audio, and video files, among other things.
