Network and information security: A computational intelligence approach Special Issue of Journal of Network and Computer Applications

摘要

The global economic infrastructure is becoming increasingly dependent upon information technology, with computer and communication technology being essential and vital components of Government facilities, power plant systems, medical infrastructures, financial centres and military installations to name a few. Finding effective ways to protect information systems, networks and sensitive data within the critical information infrastructure is challenging even with the most advanced technology and trained professionals. The increasing number of Information Security (IS) related incidents, organized crimes and phishing scams mean that IS deserves much closer attention. Efforts must be stepped up to ensure a safe and secure IT environment throughout the globe. It is important to bear in mind that effective security cannot be achieved by relying on technology alone. A tight coordination is required between the people and technology and weakness in one of these could directly affect the security. Some of the leading challenges which administrators often face when a decision is made to design, develop and implement IS technologies into a security system are cost benefit analysis, trade-off analysis between increased security and privacy and convenience and how the new technology will be used.
