    No full text
    Abstract. Detecting illegal resource access in the setting of grid computing is similar to the problem of virus detection as put forward by Fred Cohen in 1984. We discuss Cohen’s impossibility result on virus detection, and introduce “risk assessment of security hazards”, a notion that is decidable for a large class of program behaviors. Keywords: Malcode, Program algebra, Thread algebra, Virus, Worm.
