The cognitive area of Security in Information and Communication Technologies (ICT) is already attracting significant interest not only from researchers and scholars but from the entire range of professionals in the field. This interest is reflected, among other things, in the stance of universities and technological educational institutes that have incorporated a series of related courses into their undergraduate and postgraduate programs.

The book is the result of a collective effort by specialists with long-term research, study, and teaching experience in the area of Security in ICT. It is aimed at students, scientists, and technologists in the ICT field who wish to acquire the necessary knowledge to engage fruitfully and creatively with this area. It also addresses every professional in ICT, as the horizontal nature of this cognitive area ensures that sooner or later they will be called upon to deal with issues that fall under it, regardless of their professional status.

The topics discussed include the conceptual foundations of the cognitive area, identification and authentication, identity management technologies, access control, security policies and formal models, operating system security, database system security, malicious software, assurance and evaluation of system and product security, approaches to information systems security, risk analysis, assessment and management, security policies, information systems auditing, and personal data protection.

The book also includes two appendices with the EU directives 1995/46 and 2002/58 for the protection of personal data. The scientific editors of the book are university teachers who have been engaged in research and study related to Security in ICT for more than fifteen years. At the same time, they teach related courses in undergraduate and postgraduate programs at universities and technological educational institutes and systematically participate in the developments of this cognitive area at both national and international levels.
