Abstract
With rapid development of computer systems and after being attacked again and again by many kinds of viruses, it is necessary for us to check whether the structure of our existing computer system is secure. It is true that our existing computer system is a highly intelligent information processing system. However, with the increase of our knowledge and the progress of research, we gradually realize that there is still a large distance between machine and biological intelligence. This is why computer systems usually appear very passive when meeting the attack of a novel virus. Therefore, it is still an important aspect of our research which is how artificial intelligence learns from biological systems.
In computer systems, the techniques used for fighting computer viruses depend mainly on anti-viruses software rather than an immunity system for protecting computer systems. With regard to biological intelligence, an individual mainly depends on the immune system to protect its body against harmful intrusion from outside. Without this system, an individual cannot live, even just several days. Based on this consideration, we try to design and develop a model with the ability of imitating natural immune function.
Natural immune systems offer an inspiration for mathematical modeling and computer simulation, which leads to the creation of a new research field of computer science called ”artificial immune systems”.
This thesis presents the designing issues of the computer’s immunity system against computer viruses and studies of different ways of detecting errors in the data transferred across computer networks and different ways of electronic signature. The thesis includes the following tasks:
1. Defining the computer viruses, their Structure and Operation, describing the computer viruses’ life cycle, demonstrating the analogy between biological and computer viruses, defining the different computer viruses types, and listing the symptoms of virus infection.
2. Reviewing anti-viruses techniques by describing the anti-virus’ work, defining the different anti-viruses detection techniques, making a comparison between the
different anti-virus detection techniques, and defining the verification, quarantine, and disinfection terms.
3. Studying the data integrity by defining the ways of detecting the error in data transferred across the computer network and electronic signature.
4. Designing a computer’s immunity system by determining the computer system components prone to viruses’ infection, the infection media and the mechanism used to detect illegal changes in the computer system components, and listing the proposed immunity system activities.
5. Finally, evaluating the performance of the proposed immunity system and the different detection techniques by performing a computer system simulation.
