The International Conference on Risks and Security of Internet and Systems 2014 is the ninth in a series dedicated to security challenges related to Internet applications, networks and systems. In recent years, the Internet has become essential for the exchange of information between user groups and organisations from different backgrounds and with different needs and objectives. These users are exposed to increasing security and privacy risks, due to the development of sophisticated on-line attacks, the growth of cyber-crime, etc. Contemporary attackers are motivated and are increasingly experienced. To compound matters, sophisticated tools that facilitate attacks are readily available. Moreover, the increasing complexity and the vulnerabilities in newer technologies such as pervasive, mobile and wireless devices and networks, raise new security challenges.
In this context, new security mechanisms and techniques are needed to achieve an acceptable level of assurance for critical domains such as transportation, health, defence, banking, critical infrastructures, embedded systems and networks and avionics systems. The CRiSIS conference offers an effective forum for computer and network security researchers from industry, academia and government to meet, exchange ideas and present recent advances on Internet-related security threats and vulnerabilities, and on the solutions that are needed to counter them.
