Security and Evolution

In software development there seems to be an inherent 'arms race' around security. External predator software to breach software's security holes is in constant 'arms race' with the software's capacity to repel them. This kind of tense relationship recalls eternal struggle between prays and predators in nature. The pray develop a defense mechanism and survive better and longer say with a camouflage, then the predator develops a counter-measure and the arms race continues indefinitely (people will always attack browsers, browser vendors will always have to deal with them).
