Summary on Grant Application Form
The central challenge with computer security is determining the difference between normal and potentially harmful activity. For half a century, developers have protected their systems by coding rules that identify and block specific events. However, the nature of current and future threats in conjunction with ever larger IT systems urgently requires the development of automated and adaptive defensive tools. A promising solution is emerging in the form of Artificial Immune Systems: Our bodies can detect and defend themselves against harmful and previously unseen invaders, so can we not build a similar defence mechanism for our computers? Current Artificial Immune Systems have been successful on test systems, but the algorithms were unable to scale up to real-world requirements. This is caused by their reliability on self-nonself discrimination, as stipulated in classical immunology. However, immunologist are increasingly finding fault with traditional self-nonself thinking and a new 'Danger Theory' is emerging. This new theory suggests that the immune system reacts to threats based on the correlation of various (danger) signals. Little is currently understood of the precise nature and correlation of these signals and the theory is a topic of hot debate. It is the aim of this research to investigate this correlation and to translate the Danger Theory into the realms of computer securitv. therebv creatina Artificial Immune Svstems that are no lonaer limited by self-nonself discrimination.
