Computer piracy and digital forensic analysis strategies
Introduction
Among the strategies to prevent cyber attacks, the digital forensic analysis, also known as Forensic Informatics, which consists of the application of techniques to find value information techniques,. He is also able to conduct scientific investigation to attacks such as software and hardware piracy, and crimes such as intrusions, Hawking in organizations, spam, phishing, kidnappings of computer data, child pornography, among others. The digital forensic analysis was born in the 80s when the FBI analyzed some electronic devices within the US Department of Justice.
Developing
This practice became popular among people who was looking for evidence in computers, servers and other teams. Today, it is a fundamental aspect within business, governments and individuals. Hence, it has become a professional prestigious career, whose expert is known as Forensic Computer Expert. Because it is necessary? Its use is mainly preventive and serves to audit the protection mechanism and safety strategies in any company information systems.
It also allows to detect vulnerabilities and correct them, if there is the case that the company’s safety has been violated, in digital forensic analysis allows you to collect probative traces to find out the origin of the attack, manipulations, leaks or data destruction. In this technique, any evidence must be preserved in its original form, while a structured investigation of the fault is carried out. The expert: expert in forensic analysis. The use of technology in any organization, its database and information systems, could be the target of cyber attacks or cybercars.
The forensic computer expert helps plan prevention strategies and safety measures, using specialized software to access information regardless of the device in which you are. They even have tools capable of extracting the images taken from mobile phones and knowing if modifications have been made while the investigation lasts. Phases of digital forensic analysis, this technique has a series of phases. Between them:
The identification: in a previous analysis the elements are identified and the methods to be followed during the process are determined. In addition, all the initial information is raised: Date of the incident, duration and details of the same. A copy is made with an appropriate tool to remove exact images of hard drives for later analysis. Validation and preservation: a series of actions are carried out that allow the data to be conserved without being modified, while an exact record of those who have had access to the team is made.
Similarly, in this phase two copies of the evidence obtained must be taken and the analysis of the copy to maintain the original intact will be made. This is done in order to verify that the evidence has not been altered. Analysis: This is the most technical stage and it will analyze both software and hardware from the original support. The expert will extract all the information and filter the valuable data. The files, list of users, documents, emails, encryptions, latest connections and conversations records are analyzed, among others.
You will also use tools to detect where the attack could come, the IP address and identify the type of attack they have made and if you did a hacker or a computer professional. Documentation and presentation of tests: Once the previous phases have been carried out, a report will be lifted objectively and orderly with all the information collected from the device. It also includes the original device and copies made. Cybersecurity and digital forensic analysis: cybersecurity and digital forensic analysis are complemented as equipment and are fundamental when investigating cybercrime.
However, the first focuses on preventing and detecting attacks and then designing safe systems, while digital forensic analysis investigates the consequences of the incident. Free distributions for digital forensic analysis: the computer expert must have at hand his tools with which he will carry out the corresponding expertise. Here the best three free Linux distributions that will be useful in a forensic investigation.
CAINE 7 (COMPUTER AIDE INVESTIGATION ENVIRONMENT) This distribution that has a series of applications. It is based on Ubuntu 14.04.1. And allows blocking devices such as records or storage units and getting in reading mode. It has an easy and intuitive graphical interface that will help exploit a large number of applications. It can be used by starting the system from a pendrive. SIFT (Sans Investigative Forensic Toolkit) was developed by forensic experts, with support from Sans, based on an open source distribution (Ubuntu).
It has a Forensic Tool Kit and quick guides on the most used commands or operations. With it you can create timelines, collect volatile memory and use tools such as Sleuthkit or Autopsy. As is a very used system for some courses, there are many research developed based on its use and a very active consultation forum. #3 Def 7 (Digital Evidence and Forensic Toolkit) is composed of a GNU / Linux system dedicated to digital forensic science and intelligence activities. It is also based on Ubuntu 14.04.02 lts and only need 400 MB of RAM to be able to run correctly.
conclusion
To guarantee a good job you must make sure you have a really professional and experienced team. As well as having the right tools to obtain the evidence that is valid in judicial processes. Most of the systems developed for forensic analysis respond to different standards or methodologies, present when classifying and ordering forensic instruments within the menu options of the distributions described above. In order to obtain a satisfactory digital forensic analysis, it is necessary.
