To understand this, let us take an instance. For example, if an investigative agency is trying to prove that a suspect has indeed committed a crime like identity theft, digital forensics investigators use a set of highly sophisticated methods. It helps them to go through the suspect's email account, hard drives, social networking sites, and other digital footprints that can act as suitable evidence of the crime.

Before going ahead with the investigation, the concerned investigator must state the type of evidence sought modified or accessed.

Presentation of findings- Lastly, it is time to put everything together and present the findings of the investigation. The presentation should include a summary of the case, the investigation procedures that were followed, and a detailed analysis of the evidence that was found.

The presentation should also include a clear and concise report on the findings of the investigation, including any conclusions that were reached based on the evidence.

A well-presented report is critical because it will be used to assist in court proceedings or other legal actions that may be necessary.

In conclusion, digital forensic investigation has become an essential tool in modern law enforcement. It allows investigators to track and prosecute cybercriminals, safeguard personal and sensitive information, and protect the interests of individuals and countries.

By following strict procedures and guidelines, investigators can collect and analyze digital evidence effectively and present their findings in a clear and concise manner. It is a complex and constantly evolving field, but with the right training and experience, investigators can stay ahead of the game and successfully fight cybercrime.
