Science, Nov 17, 1995: "Security Schemes Aspire to No Fuss System Protection." Because of the painful trade offs between security and usability that come with current protective measures, computer scientists have heen investigating new ways to detect and ward off intruders that present fewer obstacles to users and administrators. Two of the most intriguing directions announced at the Baltimore security conference were reported by researchers at Purdue University's Computer Operations, Audit, and Security Technology laboratory (COAST). The first was an attempt to harness techniques from artificial intelligence to detect intrusions; the second, a pilot test of what has been called software forensics -- an effort to recognize malign programs by identifying the fingerprints of their creators.
