....3. 1 Physiology of viruses and worm programs Physiology is defined as The study of all the functions of a living organism or any of its parts [Websters 98] Previous researchers have shown that computer viruses are artificial life forms, performing similar functions as biological life forms [Spafford 94, Witten 90] This work extends the analogy further by identifying and studying the functional organs of virus and worm programs. In Figure 3 1 we present an abstract model for an organ. 15 Definition: An organ is defined as a 4 tuple subject, action, object, function . 1. Object: An object is ....

....were discussed in [22] in the context of tamper proofing soft ware watermarks. 4.1 Tamper Proofing Viruses It is interesting to compare the work done on software protection with the on going struggle between virus writers and virus detector writers. A computer virus [11] 18] 19] [80] is a piece of code that has the ability to reproduce by attaching itself to other programs, disks, data files, etc. Most viruses are malicious, performing destructive operations on infected systems, although good viruses have also been discussed. Virus writers employ many obfuscation like ....

....has already made progress in each of these areas. The following text details a few significant results. Since 1987, COAST faculty and students have been exploring issues in practical computer security. Their work has included widely cited work in analysis of malicious code including viruses (e.g. [11, 10, 12, 13, 14]) In 1991, COAST director Gene Spafford coauthored the award winning book Practical UNIX and Internet Security[17] now considered the standard reference in the field. He has also been involved in work on static audit and analysis tools. An initial result of this work was the COPS[5] security ....
