By capturing and preserving relevant electronically stored information (ESI) and documenting pertinent information, such as visual images, as well as how it was obtained, this program safeguards relevant ESI.
Fremont, CA: Keeping, analyzing, retrieving, and preserving electronic data that may be useful in an investigation is called digital forensics. A digital device can store data from a hard drive in a computer, a mobile phone, a smart appliance, a navigation system in a vehicle, an electronic door lock, and many other types of devices. A digital forensic process aims to collect, analyze, and preserve evidence.
After understanding what digital forensics is, let's look at its procedures:

• The identification process
In this stage, the sources of significant evidence are identified as individuals or devices to be analyzed.
• The preservation
By capturing and preserving relevant electronically stored information (ESI) and documenting pertinent information, such as visual images, as well as how it was obtained, this program safeguards relevant ESI.
• An analysis
It involves examining the evidence provided by the information collected methodically. In this examination, data objects are created, including system and user-generated files, and conclusions are drawn based on specific answers and points of departure.
• Documentation
Using these methods, other competent examiners can read through and duplicate the results of the analysis.
• Presentation
For an investigation to be successful, digital information must be collected, which may mean removing electronic devices from the crime or incident scene and copying or printing them.
Objectives of Digital Forensics
In order to fully comprehend what digital forensics is, it is essential to understand its primary objectives:
• Assists in the recovery, analysis, and preservation of computers and related materials so that they can be presented as evidence in court
• Identifying the primary perpetrator and the motive for the crime is assisted by it.
• Preventing tainted digital evidence from being obtained from a suspected crime scene by establishing procedures
• Recovery and duplication of deleted files from digital media in order to extract and validate evidence
• Allows you to quickly identify evidence and estimate the potential impact of malicious activity on a victim
• Providing comprehensive information on the investigation process through a computer forensic report
• Assuring the safety of evidence by adhering to the chain of custody
Types of Digital Forensics
A number of sub-disciplines have emerged as digital data forensics evolved, including:
As part of ongoing investigations and legal proceedings, it analyzes digital evidence obtained from laptops, computers, and storage media.
• Device forensics for mobile devices
A portable device can be an electronic assistant, a mobile phone, a tablet, a SIM card, or a gaming console used to collect evidence.
