Security in information systems: Advances and new challenges

摘要

Information Systems Security is one of the most pressing challenges currently confronted by all kinds of organizations. Information systems undoubtedly play an important role in today's society and are increasingly at the heart of critical infrastructures. Although many companies have discovered how critical information is to the success of their business or operations, very few have managed to be effective in maintaining their information secure, avoiding unauthorized access, stopping intrusions, preventing the disclosure of secret information, etc. In any computer-related environment, it is possible to consider security as a non-functional requirement that maintains the overall system usable and reliable, and protects the information and information systems.
