The issue of online privacy and security is a challenging subject, as it concerns the privacy of data that are increasingly more accessible via the internet. In other words, people who intend to access the private information of other users can do so more efficiently over the internet. This study is an attempt to address the privacy issue of distributed big data in the context of cloud computin...

Reports and press releases highlight that security incidents continue to plague organizations. While researchers and practitioners’ alike endeavor to identify and implement realistic security solutions to prevent incidents from occurring, the ability to initially identify a security incident is paramount when researching a security incident lifecycle. Hence, this research investigates the abili...

This paper reports a study that challenges the widely-held assumption that security and functionality are a tradeoff relationship. Based on a survey sample of more than 9000 French firms, the study finds that higher degrees of system functionality entail higher degrees of security. Rather than sharing a tradeoff relation in which more security investments entail an opportunity cost in terms of ...

The design and implementation of intrusion detection systems (IDS) remain an important area of research in the field of security of information systems. Despite the undeniable progress, much remains to be done to improve the security of computer networks today. For this, many mechanisms have been developed {[1], [2]}. In general, these systems are vulnerable to attack from unauthorized users (e...

This paper presents a model of a secure collaborative application for conducting real-time electronic meetings from remote locations. The application consists of a set of tools, enabling common meeting tasks to be accomplished. The tools can be enhanced with security services at will. The security architecture comprises the standardized communication security services 14], as well as the \group...

The concepts for secure e-mail are available for quite some time. Nevertheless only few users have adopted them. The classical concept of end-to-end e-mail security provides maximum theoretical security. But the effort to implement and enforce it at every client has limited the spreading of security and therefore the overall benefit. Centralized e-mail security overcomes this problem. A gateway...
