Most organisations try to protect their systems from unauthorised
access, usually through passwords. Considerable resources are spent
designing secure authentication mechanisms, but the number of
security breaches and problems is still increasing (DeAlvare, 1990;
Gordon, 1995; Hitchings, 1995). Unauthorised access to systems, and
resulting theft of information or misuse of the system, is usually
due to hackers "cracking" user passwords, or obtaining them through
social engineering. System security, unlike other fields of system
development, has to date been regarded as an entirely technical
issue - little research has been done on usability or human factors
related to use of security mechanisms. Hitchings (1995) concludes
that this narrow perspective has produced security mechanisms which
are much less effective than they are generally thought to be.
Davis & Price (1987) point out that, since security is
designed, implemented, used and breached by people, human factors
should be considered in the design of security mechanism. It seems
that currently hackers pay more attention to human factors than
security designers do. The technique of social engineering, for
instanc- obtaining passwords by deception and persuasion- exploits
users' lack of security awareness. Hitchings (1995) also suggests
that organisational factors ought to be considered when assessing
security systems. The aim of the study described in this paper was
to identify usability and organisational factors which affect the
use of passwords. The following section provides a brief overview
of authentication systems along with usability and organisational
issues which have been identified to date. 1.
