Nowadays, cybercrime is on the rise and according to the briefings given by the local police authorities in many countries, the number of digital forensics cases are increasing in a steady manner. Initially, the industry literature used the term ‘computer forensics’ for designation of the specific branch of forensic science that deals with the investigation and recovery of different materials found in computers.
Then, the field expanded to digital forensics for covering areas of analysis and enquiry of different devices that can store data digitally. These investigations are generally performed with respect to a crime and this is why it is made essential that digital forensics investigators in Milwaukee or any other part of the world for that matter should undergo necessary training and they should also gain some field experience as well. The work of such an investigator is different from that of a network or system administrator.
Application: In most of the cases, digital forensics investigators in Milwaukee are used to discredit or support hypotheses before the court of law, regardless of whether it is civil or criminal. In the case of electronic identification, an investigator can also prove helpful for private sector organizations as well. Regardless of the organization for which they work, the job of these professionals follow a typical process that starts with the seizure of media and it will continue with the acquisition called as Forensic imaging.
Generally, these investigators, who can also be called as computer forensic analysts will look for as much information as possible before they take any step towards the work handed over to them. Initially, they will generally begin with investigating the people, who provide information related to the case.
Technical procedure: The technical procedure will begin with the collection of volatile evidence. The important point here to remember is that these are data that can disappear or change quickly, if not handled properly. Once this step is successful, based on the level of access, the investigator will have the digital device or computer for collection of physical storage, inclusive of USB drives, hard drives and memory cards. These will be forensically imaged with a view to ensure the continuity of the operational system, while the devices will also be used as evidence.
So, the professional world of a computer forensic analyst is something fascinating, but it is challenging and demanding as well. Good professionals would have earned best training and experience in this field and they can provide the best help to their customers.
