The purpose of this paper is to analyse the problems associated with the development of e‐government in Southern Africa Development Community (SADC) countries and propose a novel framework for adopting service orientation. This framework includes a new approach and architecture for implementing service orientation called SBA‐eGOV (Service Based Architecture for E‐Government).

A comprehensive literature review was carried out to study various service oriented architecture (SOA) adoption strategies and implementation methods. The most appropriate adoption strategy and implementation method were selected. Web service adoption and implementation/development methodologies were designed separately, and then integrated to form one single framework. Web services best practices were studied to identify the specificities of web services for e‐government projects in SADC countries. A service orientation framework, which includes a service orientation development/implementation method, was developed for e‐government projects. Data from the UN report on e‐government readiness for year 2004‐2010 were analysed.

The trend showed that the e‐government index of SADC countries has been stagnating (even degrading) since 2005. One of the main reasons is the lack of software application integration. The main area of weakness is the lack of a complete framework for adopting and implementing web services. A framework for adopting service orientation, developing web services and deploying e‐services is required to enable application software integration.

By applying the proposed framework, e‐services can be deployed more rapidly to citizens, businesses and government departments.

SBA‐eGOV can be adopted by countries where e‐government projects have completed the “Internalisation” and “Interaction” stages and use to deliver e‐services to citizens.

This work comprises development of a new framework, SBA‐eGOV, which consists of a service‐orientation adoption methodology, a service‐orientation implementation methodology and a service‐based architecture for government. SBA‐eGOV is a novel and complete framework which addresses service‐orientation adoption, development and implementation. To date, no such research work has been undertaken to analyse and solve the problems surrounding e‐government projects in SADC.

Highly sensitive information pertaining to citizens and government transactions is processed in an electronic format, making information security a critical part of e-Government applications and architectures. Information security measures should ideally span from authentication to authorisation and from logical/physical access control to auditing of electronic transactions and log books. The lack of such measures compromises confidentiality, integrity and availability of information. Today, most e-Government projects in developing countries in Southern Africa Developing Community (SADC) face challenges in two main areas, namely, information security and application software integration. This paper aims to discuss and analyse the information security requirements for e-Government projects and proposes an information security governance model for service-based architectures (SBAs).

The current state of information security in emerging economies in SADC countries was researched. The main problems identified were the lack of software integration and information security governance, policy and administration. The design consists of three basic layers: information security governance defined at the strategic level of the government; information security policy/management defined at the management/operational level; and information security measures, implemented at the technical level. This section also proposes a policy for implementing public key infrastructures to protect information, transactions and e-services. A Token-Ring-based mechanism for implementing Single-Sign-On has also been developed as part of this study.

The main problems identified were the lack of software integration and information security governance, policy and administration. These challenges are causing e-government projects to stagnate.

The proposed approach for implementing information security in e-Government systems will ensure a holistic approach to ensuring confidentiality, integrity and non-repudiation, allowing e-Government maturity to progress from “interaction” to “online transaction” stage in emerging economies.

Research has not focused on developing a solution for emerging economies which are facing difficulties in integration software applications to deploy end-to-end e-services and to produce an underlying identity management architecture and information security governance to secure the e-services developed and deployed using an SBA. The work produced in this paper is specific to SBAs in e-government environments where legacy systems already exist. The work includes: information security governance defined at the strategic level of the government; information security policy/management defined at the management/operational level; and information security measures implemented at the technical level. This section also proposes a policy for implementing public key infrastructures to protect information, transactions and e-services. A Token-Ring-based mechanism for implementing Single-Sign-On has also been developed as part of this study.
