Maturity models in the hospital information systems management initial research

Os modelos de maturidade são instrumentos facilitadores da gestão das organizações, incluindo a gestão da sua função sistemas de informação, não sendo exceção as organizações hospitalares. Neste artigo apresenta-se uma investigação inicial que visa o desenvolvimento de um abrangente modelo de maturidade para a gestão dos sistemas de informação hospitalares. O desenvolvimento deste modelo justifica-se porque os modelos de maturidade atuais no domínio da gestão dos sistemas informação hospitalares ainda se encontram numa fase embrionária de desenvolvimento, sobretudo porque são pouco detalhados, não disponibilizam ferramentas para determinação da maturidade e não apresentam as características dos estágios de maturidade estruturadas por diferentes fatores de influência.

Security management : modelling critical infrastructure

Secure management of Australia's commercial critical infrastructure presents ongoing challenges to owners and the government. Currently a high-level iriformation sharing collaboration between the government and business manages complex security issues, but critical irifrastructure protection also lacks a scalable model exhibiting the overall structure of critical infrastructure at various levels, sectors and sub-sectors. This research builds on the work of Marasea and Warren (2003) to establish a representative model of Australia's critical irifrastructure; discusses the boundaries between critical infrastructures, and considers the existence andpotential irifluence ofcritical irifrastructure relationships.

A methodology of health information security evaluation

With the conversion of paper health records to electronic health records, the health care sector is increasingly relying on technology to maintain the integrity of and update patients’ data. This reliance on technology requires an acute level of protection from technological disasters and/or threats of human error or sabotage. Research has shown there are inadequacies in the installation and use of security controls for health information records and that current methods of security analysis lack the techniques to analyse the technical and social aspects of security. This paper reports on progress towards development of a health information security evaluation methodology based on Unified Modelling Language techniques, and discusses an imminent case study that will be used for validation of the methodology.

A security evaluation criteria for baseline security standards

Recent advances in technology and new software applications are steadily transforming human civilization into what is called the Information Society. This is manifested by the new terminology appearing in our daily activities. E-Business, E-Government, E-Learning, E-Contracting, and E-Voting are just a few of the ever-growing list of new terms that are shaping the Information Society. Nonetheless, as "Information" gains more prominence in our society, the task of securing it against all forms of threats becomes a vital and crucial undertaking. Addressing the various security issues confronting our new Information Society, this volume is divided into 13 parts covering the following topics: Information Security Management; Standards of Information Security; Threats and Attacks to Information; Education and Curriculum for Information Security; Social and Ethical Aspects of Information Security; Information Security Services; Multilateral Security; Applications of Information Security; Infrastructure for Information Security Advanced Topics in Security; Legislation for Information Security; Modeling and Analysis for Information Security; Tools for Information Security. Security in the Information Society: Visions and Perspectives comprises the proceedings of the 17th International Conference on Information Security (SEC2002), which was sponsored by the International Federation for Information Processing (IFIP), and jointly organized by IFIP Technical Committee 11 and the Department of Electronics and Electrical Communications of Cairo University. The conference was held in May 2002 in Cairo, Egypt. This volume is essential reading for scholars, researchers, and practitioners interested inkeeping pace with the ever-growing field of Information Security.

Australian SMES and e-security guides on trusting the internet

There have been many standards and guides written for the implementation of computer security and information security concentrating on appropriate implementation of procedures for effective information security management. Such guides are limited when dealing with e-business and its implementation by Small and Medium Business Enterprises (SMEs). In Australia the National Office for the Information Economy (NOIE) has released a small business guide for e-security for performing such services while fulfilling the necessary security requirements. This paper presents an overview of this current small business guide to e-security with special reference to deriving a common set of criteria for implementing security measures in the SME e-business environment.

Health information security evaluation: continued development of an object-oriented method

With the convergence of paper to electronic, the health industry is relying more on technology to maintain and update the well-being of patients. This reliance on technology requires an acute level of protection from
unwanted technological disasters and/or human threats. Research shows insufficiencies with the implementation and use of security controls; as well as current analysis methods lacking the techniques to analyse technical and social aspects of security. The aim of this paper is to introduce an information security evaluation methodology for health information systems based on UML.

The multifaceted and ever-changing directions of information security - Australia get ready!

In recent years, we have witnessed many information security developmental trends. As a consequence, the dimensions of information security - once single disciplinary area - have become multifaceted and convoluted. This paper aims to (1) recapitulate these key developments: (2) argue that the emergence of many complex information security dimensions are the result of 'constant change agents' (CCAs); (3) discuss the implications on Australia's society, i. e. government, companies and individuals; and (4) propose key consideration areas and possible solutions thereof. We hope that the discussion presented here will position Australia to make better aligned information security and strategic plans, such as choosing appropriate investments and adopting effective solutions to strengthen and secure Australia's national information security posture.

E-business security management for Australian micro SMEs - a case study

Small and Medium Business Enterprises (SMEs) make a significant contribution to the economic viability of the Australian economy. The benefits of performing business in an on-line environment has been realised by Australian SMEs as the use of the Internet for performing business activities both with consumers and other businesses continues to increase. The findings of an empirical study and other evidence available indicate the uptake and advancement of performing e-business activities shall be dependent on two key complementary elements: first, the ability of Australian SMEs to secure their e-business systems; and second, the availability of an approach to recommend a practical e-business security management strategy. This paper presents the results of a case study which applied a previously developed methodology to a micro SME e-business system. The purpose was to validate the ability of the Australian Small to Medium Enterprise E-business Security Methodology (ASME-EBSM) to provide an effective security management strategy for Australian SMEs. The outcome demonstrated that this approach was both feasible and realistic for providing recommendations to secure the e-business activities performed and to protect the micro SME e-business system.

The derivation of a conceptual model for IT security outsourcing

IT security outsourcing is the establishment of a contractual relationship between an organization with an outside vendor which assumes responsibility for the organisation’s security functions. Outsourcing in IS has had a variable history of success and the complexity of the decision making process leads to a substantial degree of uncertainty. This is especially so in the realm of IS security since the protection of both hardware and software systems is placed in the hands of an external provider. This paper is a fuller and more comprehensive paper of a previous paper outlining the effectiveness of the decision making process by means of a conceptual model using Soft System Methodology techniques that integratessecurity benefits, costs and their respective performance measures. In this paper the methodology used to develop the model is discussed in detail.
