Abstract
Digital forensic analysis helps in identifying, collecting and analyzing evidence with investigations one of the first steps to establish what is required using obtained evidence. The digital forensics tools allow data replication and evaluating the electronic evidence, and in this way determine if a later analysis with other tools is justified. These tools are required to create perfect copies (forensic images) of computer data without making changes to the original evidence. The forensic images of a hard disk, driver, network, file, and mobile devices are obtained using the analysis methodology where there is preparation, extraction, identification and analysis of evidence. There is a combination of various approaches and techniques to obtain and analyze the evidence such as the forensic analysis tools and device imaging procedures. Forensic evidence was extracted using forensic tools and the electronic content was evaluated identified following collection, examination, analysis, and reporting.
Introduction 
In digital forensic analysis, there are different phases and identifying the incident followed by collecting evidence is the initial steps in the analysis process. It is also necessary to preserve the evidence before the actual analysis takes place and then documentation and presentation of the results (Akbal & Dogan, 2018). It is important essential to document everything that is done and especially the most important actions in each phase. o Investigations
Purpose
Digital forensics is the set of principles and techniques that comprise the process of acquisition, preserving and, documenting digital evidence and that, where appropriate, they can be accepted legally in a judicial process. Increasingly, there are more violations or attempts to violate the security policies and computer systems. Digital forensics analysis then highlights how to identify incidents and collect evidence analyzed and report the results of an investigation
Objective
Digital forensics will help to validate the digital forensic process and is useful to determine how best to monitor and improve network security. Collecting reliable forensic evidence is crucial to undertake the digital forensics process.o Analysis Methodology
Analysis methodology reflects all the tasks performed by the digital forensic tools, and these tools perform specific tasks including preparation, extraction, identification and analysis. Acquiring, preserving and retrieving evidence is crucial in studying the digital forensics analysis and the methodology is necessary to test the digital forensics. The forensic tools and tests to get valid results and acquiring the required tools is crucial to undertake digital forensics. Preparation 
Preparation is the plan of action that involves using the right tools and techniques is necessary as evidence gathering systems are prepared, before extracting data from the devices and the log files.
Extraction
Extraction involves recovering evidence and there is data extraction from connected devices, there is also focus on ensuing that the evidence is relevant since this affects analysis. Extraction is a challenging task and forensic inv...
