This information can be used as physical evidence. For example, we can take photos of how a suspect computer is connected and what peripherals have connected. This step includes collecting physical and digital evidence. Write down all the details in a notebook Take photos of all the relevant details to the case (If it is necessary to turn off the computer, the power cable must be pulled off from the back of the computer) If the suspect computer is off, then, do not turn it on. Do not click with the mouse or pressing any key on the keyboard. If the suspect computer is on, then do not turn it off. Look carefully all the details in the scene Keep out unauthorized personnel to the scene For them, basic techniques to secure the crime scene are: If the scene is not properly secured, then the evidence could be contaminated. Securing the crime scene (the place where a crime has been committed) involves protecting evidence that can be found in the scene. The phases of the digital forensic process are: Protect the crime scene, collect the evidence, and establish the chain of custody and examination of the evidence. 2.2 Phases of the digital forensics process Memory cards and other storage devices (National Institute of Justice, 2010). Office documents (Word, Excel, Power point)ĭigital evidence can be found in the following devices:
Content or electronically stored, for example: Tracing the origin 2.1- What is Digital Evidence?Īny document, file, record, data, etc. Two of these techniques are:ġ- Determine who used the computer? How was used? When and why?Ģ- Determine who has a remote user on the computer from someone else? Thanks to these techniques’ researchers can discover how a computer was used to commit a crime.

This implies that those involved in this new and necessary discipline must be professionals with high ethical standards and respect for institutions, for in them is support decisions on the events analysed (National Institute of Justice, 2010).įorensic investigators have professional tools and techniques that help them recreate what happened with a computer or other electronic device. 2.0- What is Digital Forensics?ĭigital Forensics is IT (Information Technology) specialization that assumes the necessary duties related with finding exhibit (evidence) at the place where a crime has been committed (crime scene) Digital forensic duties include: identify, collect, preserve, analysis, interpret, document and present evidence.

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