Abstract
Within Higher Education, concerns are growing with
regard the gap between what university central services
traditionally provide and what the academic departments
within the institution need. The Institutionally Secure
Integrated Data Environment (INSIDE) project is a
JCIEL (JISC Committee for Integrated Environments for
Learners) funded collaborative project between the
Universities of St Andrew and Durham that proposes to
address the above concerns by investigating the issues
surrounding the development and delivery of “joined up
systems for institutions”. The INSIDE project intends to
work utilising both universities’ existing information
bases to develop a model of distributed functionality. The
intention is to solve the problems at a high enough level
of abstraction to provide a generic solution applicable to
other Higher Education institutions. The model must
address security implications of “joined up systems for
institutions” balancing an institution’s need for effective
data security with universities' culture of open access to
information. An effective security strategy should address
both the technical and social issues raised by web
accessible information systems. It must give recognition
to the human and organisational aspects of security and
the need to educate users in secure working practices.
1. Background: INSIDE Project Domain
Within Higher Education (HE), concerns are growing
with regard to the gap between what university central
services traditionally provide and what the academic
departments currently need. Members of the
administrative staff and academic community (staff and
students) of institutions are finding the performance of
routine tasks difficult due to the nature of their
institution’s current systems. These systems, usually
comprised of multiple unconnected data repositories,
require a user to expend extensive effort to accomplish
what should be simple tasks. Users are often prevented
from carrying out work by inappropriate access control
mechanisms and the lack of appropriate client software.
Additional difficulties occur as a result of the numerous
ad hoc record systems developed at the departmental level
that replicate processing being done centrally, but that are
not co-ordinated with each other or central services. For
example, at the University of Durham, the centralised
Admissions department controls student records on a
Unix system known as Banner2000
1
. However, some
departments keep their own version of student records
stored locally and manipulated using local software such
as Administration and Running Continuous Assessment
with Deadlines and Extensions (Arcade) a software that
records attendance and awarded marks [6]. While student
records from Banner2000 are used initially to populate
Arcade; correction to the student records made in Arcade
are not automatically reflected in Banner2000. Instead
discrepancy reports are generated by the academic
department and sent to the centralised Admissions
department. Central services then uses the discrepancy
reports to update the student records in Banner2000.
The Institutionally Secure Integrated Data
Environment (INSIDE) project is a JISC
2
Committee for
Integrated Environments for Learners (JCIEL) funded
collaborative project between the Universities of St
Andrew and Durham that is currently addressing the
above problems. The project specifically addresses the
issues surrounding the development and delivery of
“joined up systems for institutions”. The Universities of
Durham and St Andrews are presently responding to the
need for user-centric information systems, accessible
campus-wide. The INSIDE project is part of that
response. It is intended that the project will not “throw
technology” at the problem. Instead the project is working
with the existing information base to develop a model of
distributed functionality to deliver the information
services that users in HE need securely.
