A good examiner should know how to create a floppy disk using EnCase version 7, but with an earlier DOS version of EnCase as the executable.įastBloc is a hardware write-blocking device developed for use with EnCase. Even though floppy disks are fading away, there are still plenty of legacy boxes out there for which a floppy boot disk may be needed (these systems were made in the era when CD-ROM drives were an expensive option). Remaining in its place, however, is LinEn. Starting with EnCase 6, the DOS version of EnCase is no longer available (because floppy disks are going the way of the dinosaurs). Thus, you have all the features of the traditional EnCase for DOS with the added bonus of the Linux command-line features and much faster performance.

It provides similar functionality to the DOS boot however, LinEn runs under Linux, which means that instead of a 16-bit operating system, as with DOS, you are running under a full 32-bit operating system. This utility is called Linux EnCase (LinEn). While these are legacy methods, you can still encounter older systems where such techniques become the best option.īeginning with EnCase version 5, a Linux-based utility has been included in the EnCase distribution. From there you acquire media using the drive-to-drive, network cable, and parallel cable methods. Using those boot disks, you can boot a computer into a DOS mode that is forensically sound. I’ll begin with the basics: creating boot disks in either floppy or CD format.
You should, however, be familiar with the other options or methods to use when circumstances force you to use another method to get that image. No doubt you will use one or two of your favorite acquisition methods for most of your casework. EnCase provides many options for acquiring digital evidence, some of which are available in all models of EnCase and some are available only in the Enterprise and FIM versions.Įach case is unique and presents its own set of challenges and obstacles. During that discussion, I made several references to different methods of acquiring digital evidence, both in the field and at the lab. In the previous chapter, I discussed first-response issues, from preparing yourself and equipment to processing the scene. In this chapter, I’ll discuss the various methods of acquiring the original evidence and rendering from it an image upon which you can conduct your forensic examinations.
Thus, every 1 and 0 on the original must be replicated on the copy or image. For this image to be a copy and the legal equivalent of the original, it must represent a duplicate image of the original.
The copy of the original evidence is more commonly called an image. In this manner, I preserve the original, protecting it from alteration or corruption.
