Factors influencing post implementation system security of management information systems: a case study of Nairobi city water and sewerage company, Nairobi county, Kenya
Security is a pre-requisite for any IT undertaking in a company. Although post-implementation activities are critical for the acceptance of and security of the management information systems (MIS), post-implementation strategies are, however, not emphasized in most MIS projects, because conventional project management methodologies consider that a project is over when the system or facility is operating. Requirements of MIS tend to change continuously even after the completion of the project. Some factors that pose as the greatest challenge after the implementation of management information systems include lack of senior management commitment to information security initiatives, failure of management to understand the information security issues, lack of information security planning prior to implementation of new technologies and lack of Integration between business and information security. The purpose of this study was to assess the factors effecting system security post implementation of management information system at NCWSC.
