Biological systems employ an inherently multi-agent approach for protection from external biological assault. If properly modeled and expanded to computer networking systems, new systems for information security can be designed and adopted. These approaches would be efficient and effective at not only preventing systems failure and damage from known forms of attack, they would be able to detect and limit the damage from an unknown form of attack. In this paper, the biological system is studied and compare to a computer networking system. A simple model is also developed to aid in the study of response to an attack.
