Importance of Computer Forensics Process in this article explain computer forensic process and three computer forensic investigation phases .
The rapid increase in cybercrimes, ranging from theft of intellectual property to cyber terrorism along with litigations involving large organizations, has made computer forensics necessary. The process has also led to the development of various laws and standards that define cybercrimes, digital evidence, search and seizure, methodology, evidence recovery, and investigation process.
The staggering financial losses caused by computer crimes have made it necessary for organizations to employ a computer forensic agency or hire a computer forensic expert to protect the organization from computer incidents or solve cases involving the use of computers and related technologies.
The investigators must follow a forensics investigation process that complies with local laws and established standards; any deviation from the standard process may jeopardize the complete investigation.
As digital evidence is fragile in nature, a proper and thorough forensic investigation process that ensures the integrity of evidence is critical to prove a case in a court of law.

The investigators must follow a repeatable and well documented set of steps such that every iteration of the analysis gives the same findings, else the findings of the investigation can be invalidated during the cross examination in a court of law, The investigators should adopt standard computer forensics processes so that the jury can replicate the process whenever required.
The growing number of cyber crimes has changed the role of forensics from DNA to Digital. To get in more knowledge will have to learn CHFI Course during the course will get to know Digital technologies are changing the face of business. As organizations rapidly embracing digital technologies such as cloud, mobile, big data and IOT, the context of digital forensics is more relevant than before. we can learn by live onlie also by best cyber security institute in mumbai.
Phases Involved in the Computer Forensics Investigation Process
1. Pre-investigation Phase
This phase involves all the tasks performed prior to the commencement of the actual investigation. It involves setting up a computer forensics lab, building a forensics workstation, investigation toolkit, the investigation team, getting approval from the relevant authority, etc.
This phase also includes steps such as planning the process, defining mission goals, and securing the case perimeter and devices involved.
Investigators cannot jump into action immediately after receiving a complaint or report of a security Incident, but they have to follow a specific protocol that includes gathering of plaintiff information, type of Incident, and obtaining permission and warrants for taking further action. All these processes combine to form the pre-investigation phase.

2. Investigation Phase
Considered as the main phase of the computer forensics investigation, it involves acquisition, preservation, and analysis of the evidentiary data to identify the source of crime and the culprit. This phase involves implementing the technical knowledge to find the evidence, examine, document, and preserve the findings as well as evidence. Trained professionals perform all the tasks involved in this phase in order to ensure quality and integrity of the findings.
3. Post-investigation Phase
This phase involves reporting and documentation of all the actions undertaken and the findings during the course of an investigation. Ensure that the target audience can easily understand the report as well as it provides adequate and acceptable evidence. Every jurisdiction has set standards for reporting the findings and evidence; the report should comply with all such standards as well as be legally sound and acceptable in the court of law.
