  • 5. NIST SP 800-145 definition:<br />&quot;Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.”<br />10/4/2011<br />Security in the Cloud<br />4<br />The NIST Standard for Cloud Computing<br />
  • 6. IDC – 2008<br />Security was the factor most likely to discourage the use of cloud computing?<br />72% of small (&lt;100 employees) businesses<br />63% of mid-sized (100-199 employees) businesses<br />IDC – 2011<br />50% of small businesses<br />47% of mid-sized businesses<br />10/4/2011<br />Security in the Cloud<br />5<br />First, Some Statistics<br />
