Security for Networks With Internet Access
Despite the vastly increased convenience offered by cloud computing – or perhaps because of it – IT security analysts have expressed alarm over the accelerated rate of implementation for this emerging technological advancement observing that because of "hardware virtualization, multiple users can now share the same physical infrastructure, which runs their distinct application instances simultaneously. Although it increases resource utilization, this unique multitenancy feature also presents new security and privacy vulnerabilities for user interactions" (Ren, Wang & Wang, 2012). Although a comprehensive security protocol in regards to cloud computing technology has not yet been fully implemented by the IT industry at large, the prevailing view among network security experts holds that "a multi-level cloud security model that integrates traditional access control systems with concepts such as location-based access control, data at rest encryption, data leakage prevention and data ownership ultimately should be in place to best protect agencies' sensitive data" (Berger, 2012).
