Despite the prevailing perception that powerful software and hardware are adequate solutions to minimize information systems’ security breaches, privacy remains at stake. Human factors play an important role in maintaining information security as it is evident that non secure practices applied by employees may increase the vulnerability of the systems and lead to privacy issues. Non secure practices found in literature are related to the use of Internet, the use of emails, password management, information handling and incidence reporting. For this purpose a survey was designed to be conducted in seven hospitals in Greece in order to record non secure practices applied by nursing staff and identify correlation factors. This paper presents the reliability test of the HAIS-Q tool which was applied in order to conduct the survey entitled: Examining the Nurses’ non secure IT practices in Greek Hospitals as well as the preliminary results of the study.
