An Assessment of the Effect of Information Security Management System on Organisational Performance

This study examines the effect of an Information Security Management System (ISMS) on organizational performance in a Small and Medium Business (SMB), with a focus on Red Mango Ltd. The study employed a correlational survey design to assess the relationship between ISMS implementation and organizational performance. Primary data was collected from 44 respondents, including management and staff, through structured questionnaires. The convenience sampling technique was used for respondent selection, and data analysis was conducted using the Statistical Package for Social Sciences (SPSS) version 25. Correlation and regression analyses were applied to determine the relationship and effect of ISMS on organizational performance. Findings revealed that ISMS is well-implemented at Red Mango Ltd, with clear policies, structured roles and responsibilities, and comprehensive employee training on security measures. Employees are well-informed about acceptable usage of information security systems, and security incidents are promptly reported. However, several challenges hinder ISMS implementation, including leadership issues, technical system difficulties, personnel constraints, and financial limitations. Despite these challenges, ISMS adoption has led to significant benefits, including regulatory compliance, optimized business processes, cost savings, improved information security awareness, enhanced company reputation, and increased productivity. The study further established a strong positive correlation between ISMS implementation and organizational performance at Red Mango Ltd. Regression analysis indicated that a unit increase in ISMS adoption results in a 0.495 increase in organizational performance, confirming its significant impact. The study concludes that effective ISMS implementation enhances security, improves operational efficiency, and contributes to overall business success. Organizations are encouraged to address implementation challenges through leadership commitment, technical capacity building, and financial investment to fully realize ISMS benefits.
