The basic process of electronic data forensics

The basic process of electronic data forensics is as follows:

Fixed Preservation: Bit-for-bit read-only copying of computer storage media is preserved, and for the memory of the running system is vulnerable to loss of data for the mirror image is exported.

Deletion recovery: usually includes recovery of deleted files based on different file systems, as well as full disk scanning of storage images to recover deleted file content or fragmented information based on file type characteristics.

Trace analysis: is an important step in computer forensics analysis. Depending on the operating system used, it usually includes file downloads, program execution records, and file usage traces.

In addition, the electronic data forensics to comply with the principle of prior registration, process records.

The basic process of electronic data forensics also includes the following steps:

System analysis: an in-depth analysis of the overall structure of the computer system, to understand the system's operating mechanisms and processes, in order to better understand the flow of data in the system and the way to store.

Data Extraction: Extracting relevant data from the system according to forensic needs. This may include extracting files from a hard disk, records from a database, or fetching running data from memory.

Data Analysis: Extracted data is analyzed in depth to find evidence relevant to the case. This may include techniques such as text analysis, image analysis, and data mining.

Data presentation: presenting the analyzed data in an easy-to-understand manner so that it can be understood and used by forensic personnel. This may include creating reports, producing charts, and other forms.

Discovery conclusion: based on the results of the above steps, a conclusion is drawn about the evidence that meets the standard of proof.

Courtroom Presentation: explaining the evidentiary conclusions and their basis to the judge, jury, or relevant law enforcement personnel in a courtroom, either orally or in writing.

Electronic data forensics is a complex and requires specialized skills in the process, the need for forensics personnel with computer science, law, data analysis and other aspects of knowledge and skills. At the same time, electronic data forensics also involves many regulatory and ethical issues, the need to comply with the corresponding legal and industry norms.
