Nowadays the use of computers is increasing more and more. This has allowed the development of the internet. In turn, the Internet has brought many benefits, but the internet has also contributed to the rise of cyber-crime. So, with the rise of cybercrime, it has become critical to increase and develop computer systems security.
Each time, the techniques used by cybercriminals are more sophisticated, making it more difficult to protect corporate networks. Because of this, the computer security of these companies has been violated, and it is here at this point when digital analysis forensic is needed to discover cybercriminals.
So, with the rise of cybercrime, digital forensics is increasingly gaining importance in the area of information technology. For this reason, when a crime is done, the crime information is stored digitally. Therefore, it must use appropriate mechanisms for the collection, preservation, protection, analysis and presentation of digital evidence stored in electronic devices. It is here that the need arises for digital forensics.
In this report, I am going to explain what digital forensics is. Also, I will describe some forensic software and hardware and the importance of suitable forensic labs. So, let’s start.

Excerpt from the Book
3.1- The Sleuth Kit and Autopsy:
This is a kit of commands lines for system analysis. This valuable forensic software helps us to navigate through the files from the suspect computer without altering anything on this computer. In addition, this forensic tool like many others is able to show us a detailed list of deleted files and hidden files. It also supports various types of partitions such as sun, Mac, BSD, DOS and others. This helps us to identify certain partitions in particular to find digital evidence. However, a disadvantage of this forensic tool is that you must to memorize all commands, and it is tedious but is here in this part when Autopsy can help.
Autopsy is a forensic tool with a graphical user interface and browser to analysis evidence. Autopsy can analysis different types of data format such as FAT, Ext2 / Ext3, NTFS, etc. Autopsy is Open Source and can run on UNIX platforms. Also, we can install and runs autopsy on Windows environments. Autopsy is based on HTML, So, this feature permits the connection with the server of Autopsy employing a web browser. Also, deleted files and data are shown by an interface of Autopsy called "File Manager”. For these reasons, Autopsy is a very popular forensic tool to find evidence (Autopsy, 2013-2015).

The work primarily deals with the application of digital forensics to address computer crimes, focusing on the tools and techniques used to identify and secure evidence.
What are the central themes discussed in this report?
The main themes include the identification of digital evidence, the forensic software and hardware tools used to process it, and the design of forensic laboratory environments.
What is the primary goal of this research?
The goal is to explain what digital forensics is and to describe the professional software and hardware instruments necessary for conducting a thorough digital forensic investigation.
Which scientific methodology is used?
The work follows a systematic forensic investigation methodology, covering stages like protection of the crime scene, collection, chain of custody, and examination of evidence.
What topics are covered in the main part of the report?
The main part provides detailed descriptions of forensic software, specialized hardware like FRED and Talon Enhanced, and the functional layout of a forensic laboratory.
Which keywords define this work?
The work is defined by terms such as digital forensics, cybercrime, evidence, forensic tools, forensic software, forensic hardware, and laboratory management.
Why is the chain of custody considered vital?
The chain of custody is essential because it represents the entire life cycle of evidence, ensuring its integrity and protection from the moment of collection until the final report.
How does the author evaluate the software tools mentioned?
The author performs a comparative review, noting that while software like Autopsy is useful, proprietary or alternative tools like ProDiscover Basic may provide more comprehensive reports.
