Security Applications of Bootable Linux CD-ROMs

CD-ROM readers have been a part of the standard PC configuration for some time, and CD-R writers are close behind. CD-R writers and CD-R media are becoming increasingly inexpensive. The unit cost of media bought in bulk is low enough to make CD-Rs as disposable as paper cups - use it once and throw it away (a new opportunity for dumpster divers!). They are supplanting floppy disks and Zip disks. Their shelf life is said to be comparable to tapes. This paper skimmed over some of the possible Linux security applications of CD-ROMs, and discussed two projects in some detail. The resources section contains links to more information about some of the tools mentioned in this paper, as well as some related projects not mentioned. The number of tools intended to assist in the creation of bootable CD-ROMs is growing. The author hopes this paper will inspire the reader to think of more creative uses for CD-ROMs in the field of security.
