Computer Forensics Software
Computer forensics is the art of collecting, preserving and analyzing data present in any kind of digital format. Computer forensics software applications have today replaced the human forensics experts in retrieving such kinds of data from almost all kin sod electronic and digital media. The data can be easily retrieved from hard disks, digital media disks, digital dashboards, mobile phones, digital media players and even websites. Today, some of these software applications have become so adept that they can even determine how the data was created and transferred.
Clearly, the most important use of computer forensics software is for law investigators. Here it is mainly used to assist evidencing. Many a fraud case has been solved today by using digital forensics software.
However, it becomes necessary to invest in the right kind of computer forensics software. Here are a few features that you must look out for.
1. It must provide access to every file, cluster, nibble, bit, byte and sector of the computer.
2. It should allow an easy duplication of the disk, both through DOS and through Windows.
3. It should allow to set up a restore point when the digital medium is retrieved so that subsequent changes can be tracked. However, if there a good cloning or duplication feature, this is not necessary.
4. It should work with every system, Windows, Linux and Mac.
5. It should provide easy recovery of data, even that which has been deleted from the computer's hard disk.
6. At the same time, it should be able to forensically clean the digital medium, which means it should clean up the entire medium and replace the data present in it with zero values.
7. It should be able to capture data that had been present but now deleted from certain clusters that look empty.
8. It should be able to look at the empty spaces that are not allocated to any of the hard disk partitions and determine whether any data is present there.
9. It should be able to convert most data in the form of pure text. This helps when emails and certain documents need to be recovered.
10. Computer forensics software must also make a table of all files and directories, both currently present and those that have been deleted. This information must include the size of the files and directories, their date and time stamps and their NTFS alternate data streams.
11. It must know all the different kinds of data that are in use, such as the date formats, the kinds of integer and floating point values, etc.
12. It should be compatible with both a text search as well as a Boolean search.
13. It must automatically number all the files inside a folder and all its hierarchies so that they can be hashed for evidentiary purposes later on.
14. It should have features that allow restoration and recovery of lost data. These are only some of the features that must be present in a computer forensics software kit. Labs around the world are conducting research studies to include more and more cutting edge features each day so that modern computer forensics software has become virtually invincible.
