Nowadays, cybercrimes are grown exponentially which is consistent with the growth of technology. During digital forensic investigations, investigators are facing various kinds of issues while solving the stuff of cybercrime cases. Moreover, the task to solve case stuff has become critical for forensic teams as the volume of data to be examined is huge for the particular cyber investigation project that needs to complete with success. This article offers a solution to these problems in the form of an advanced digital forensics tool with advanced filter options.
To speed up the examination process and help digital forensic investigators to extract the evidence, investigators can opt for the advanced feature of Filtering. It can bring all the factual details of the crime to the surface. For this, digital forensic experts need a powerful forensic application such as MailXaminer Email Examiner which hosts a variety of features to simplify the very complex nature of data elements. It enables the user to filter of the suspected data in a convenient and risk-free manner.
Use of Advanced Filter Options in Digital Forensic Investigation
In digital forensics, filtering can be used to separate out the required data based on filters, so that users can examine suspected data easily without wasting the time in examining the whole data. Filters, which are inbuilt within the tool are created on the basis of GREP expressions that can be used to search desired data by matching the data strings.
Also, the GREP filter search also enables the investigators to create new filters during the process of investigation. These advanced filters can filter out data items that contain particular GREP expressions or sequences of words.
This is an efficient forensic software with a wide variety of amazing features including filtering search. The filtering search feature of the tool provides several filters that are Credit Card Numbers, Deleted, Domain Names, Emails, Internet patterns, Others, Personal Identifiers, Phone Numbers etc. Along with these inbuilt filters, users can create or define any filter for their own searches. Filters also have sub-filters wherein users can search the required data accordingly.
How to Find Deleted Files with Advanced Filter Options?
To get the deleted files, investigators can use the filter named Deleted, which can easily filter out the deleted data files. In most cases, some data files may get missed because they have been deleted by the user/cybercriminal, either accidentally or intentionally at the time of crime or post-crime. As a result, the tool can easily identify them for investigation purposes.
In order to solve and extract out the evidence from the digital crime case, investigators need an advanced forensic tool. So that they can analyze and fetch out the evidence in a more systematic way using advanced functions integrated with the tool. In the next section, we will go through the step-by-step process of advanced filters with the digital forensics software.
