On consistency and security issues in collaborative virtual environment systems

This paper survey security issues in collaborative virtual environments (CVEs) systems. In CVE, multiple users work on different computers which are interconnected through different networks to interact in a shared virtual world. Due to the nature of the geographically disperse users and their connection via different networks, there are numerous security threats that denied fulfillments of most important CVE requirements which have been ignored (e.g. consistency). In this paper, we outlined the types of collaborative virtual environment applications that can be affected by security threats and attacks, it discussed some of the most important CVE systems security requirements, and then discussed the different types of security threats and attacks related to CVE systems security requirements. Finally, we describe the state of the art of CVE system security.
