Explanation: Many organizations in a traditional data center make heavy use of physical network controls for security. Although this is a perfectly acceptable best practice in a traditional data center, this reliance is not something that will port to a cloud environment. The failure of an organization to properly understand and adapt to the difference in network controls when moving to a cloud will likely leave an application with security holes and vulnerabilities. The use of a remote key management system, monitoring, or certain programming languages would not constitute insufficient due diligence by itself.
