Wilson, "An Introduction to Software Protection Concepts," Headlines in news media include computer system breaches at popular and respected companies like Target and universities like The University of California at Berkeley. One key observation behind our approach is that a kernel hook, once initialized, may be frequently "read"-accessed, but rarely "write"- accessed. However, it remains a challenge be- cause there exist a large number of widely-scattered kernel hooks and many of them could be dynamically allocated from kernel heap and co-located together with other kernel data. Despite significant advancements in this technology, concerns about security are holding back businesses from fully adopting this promising information technology trend. To achieve productive auditing, we need to (1) accomplish efficient auditing without requesting the data location or introducing processing overhead to the cloud client; (2) avoid introducing new security vulnerabilities during the auditing process.
