As the new millennium approaches, we are living in a society that is increa
singly dependent upon information technology. However, whilst technology ca
n deliver a number of benefits, it also introduces new vulnerabilities that
can be exploited by persons with the necessary technical skills. Hackers r
epresent a well-known threat in this respect and are responsible for a sign
ificant degree of disruption and damage to information systems. However, th
ey are not the only criminal element that has to be taken into consideratio
n. Evidence suggests that technology is increasingly seen as potential tool
for terrorist organizations. This is leading to the emergence of a new thr
eat in the form of 'cyber terrorists', who attack technological infrastruct
ures such as the Internet in order to help further their cause. The paper d
iscusses the problems posed by these groups and considers the nature of the
responses necessary to preserve the future security of our society.
