“…Legacy systems play an important role in organizational operation and the failure caused by these systems will have a high impact on the organization. Legacy systems have remarkably served the organizations by delivering the intended result and therefore they bring greater business value [2]. These extremely valuable assets to the organizations represent many years of business rules, codings, data, users, experience, modifications, and enhancements needed in operating daily operations [4], [25].…”

Rapid development of information technology and communication (ICT) has increased the use of information systems in organizations since a decade ago. At the same time, many organizations are still using old information systems to support their business, known as legacy systems. Even though these systems cause technical problems, but they are still used to support service delivery to the customer. These systems are also essential to organizations as they have been operated for many years and possess high business value. The operation of legacy systems cannot be stopped quickly, as it will affect daily business tasks. However, organizations with legacy systems need to think about the ability of the systems to support their future direction. Modernization of legacy systems needs to be implemented to ensure the systems are aligned with global changes as well as improving the competitiveness of the organizations. This study, therefore, reviewed the phases and factors involved in legacy systems modernization to identify gaps and their insufficiencies. There are many studies on legacy systems, but only a few have focused on the overall process of legacy systems modernization. Most studies on legacy systems are technical in nature and refer to specific aspects and phases of modernization. This study aims to provide overall guidance to the organizations in performing legacy systems modernization.

“…The traditional information system (LIS) is a data-intensive system, composed of a large number of data files, and has significant resistance to alteration [1]. LIS resists changes caused by changing business needs [2,3]. The traditional system can meet the business needs of the enterprise and meet the functional requirements, but it lacks architecture standards [4].…”

Due to various issues such as lack of agility, low performance, security issues, and high maintenance costs, the organization replaces its legacy information system (LIS). However, with the expansion of information technology, the security of the old system has received great attention. The protection of legacy data and information is critical to the organization. However, achieving safety through modernization, redevelopment, or redesign of LIS is a time-consuming and costly solution, especially in small and medium enterprises (SMEs). In addition, newly developed systems often lose inherent business rules, data integrity, and user trust. In this paper, we propose a Security Modernization Framework (SMF) to inject security measures into LIS without modernizing the existing solution. Fundamentally speaking, SMF is a collection of methods and technologies that enhance the security structure of LIS to protect applications and old data. SMF consists of two layers of security control: data audit trail and user access authorization. This contribution has two key advantages. First, it can help SMEs protect their data and applications from unauthorized access. Second, it is the lowest cost solution to implement security measures in LIS instead of modernizing or replacing the system. SMF has used the oracle technology for authentication, but the examples are also shown in pseudocode to facilitate easy positioning of other technologies.
