Use of security and privacy tools is still limited for various reasons, including usability issues. This paper analyses usability characteristics of security and privacy tools by drawing on relevant literature and employing scenario-based questionnaires and interviews with 150 users to capture their views. Based on users' feedback, we analyse the role of usability characteristics and identify critical issues such as transparency, control of personal data, design and accessibility and consistency. This paper provides insights into the multifaceted issue of usability of security tools from the users' perspective and a comprehensive picture of users' needs and expectations. Some of the findings of this study show that users regard as important that security and privacy tools incorporate usability characteristics relevant to installation, design and accessibility, control and automation, visible feedback, and locatable security settings. Furthermore, users encounter problems with understanding technical terms and report that the availability of tools among smartphones and operating systems is a usability issue.

Research on Information Security has been based on a well-established definition of the subject. Consequently, it has delivered a plethora of methods, techniques, mechanisms and tools to protect the so-called security attributes (i.e. availability, confidentiality and integrity) of information. However, modern Information Systems (IS) appear rather vulnerable and people show mistrust on their ability to deliver the services expected. This phenomenon leads us to the conclusion that information security does not necessarily equal IS security. In this paper, we argue that IS security, contrary to information security, remains a confusing term and a neglected research area. We attempt to clarify the meaning and aims of IS security and propose a framework for building secure information systems, or as we suggest them to be called, viable information systems.

Purpose This study aims to identify the implications of security behaviour determinants for security management to propose respective guidelines which can be integrated with current security management practices, including those following the widely adopted information security standards ISO 27001, 27002, 27003 and 27005. Design/methodology/approach Based on an exhaustive analysis of related literature, the authors identify critical factors influencing employee security behaviour and ISP compliance. The authors use these factors to perform a gap analysis of widely adopted information security standards ISO 27001, 27002, 27003 and 27005 and identify issues not covered or only partially addressed. Drawing on the implications of security behaviour determinants and the identified gaps, the authors provide guidelines which can enhance security management practices. Findings The authors uncover the factors shaping security behaviour barely or partly considered in the ISO information security standards ISO 27001, 27002, 27003 and 27005, including top management participation, accommodating individual characteristics, embracing the cultural context, encouraging employees to comply out of habit and considering the cost of compliance. Furthermore, the authors provide guidelines to security managers on enhancing their security management practices when implementing the above ISO Standards. Practical implications This study offers guidelines on how to create and design security management practices whilst implementing ISO standards (ISO 27001, ISO 27002, ISO 27003, ISO 27005) so as to enhance ISP compliance. Originality/value This study analyses the role and implications of security behaviour determinants, discusses discrepancies and conflicting findings in related literature, provides a gap analysis of commonly used information security standards (ISO 27001, 27002, 27003 and 27005) and proposes guidelines on enhancing security management practices towards improving ISP compliance.
