This thesis investigates the use of a free, open source
UNIX-based operating system in providing security features
to a financially sensitive business function such as a

We start by examining some of the main security features
(such as the pf firewall and systrace policies) which are
included with the operating system, how they work and how
such features can be used within a financial environment.
We then examine possible problems with each feature and
the introduction of such a feature into the business
environment. We also explore some of the criticism that
OpenBSD has received and additional features which could
be useful to business.

We then look at some examples of statutory and regulatory
requirements, and how OpenBSD's features may be mapped to
address such requirements. As part of this we examine how
open source software in general can be utilised and some
of the advantages and disadvantages of it against similar
commercial offerings.

We then see a case study based on a real-world treasury,
and some of the serious security concerns which are faced
by security officers responsible for such departments. We
explore how OpenBSD can be applied within an infrastructure
to provide key security services and address some of the
specific concerns raised in the treasury security

Finally, we provide conclusions and suggestions for future
