After that, I think the greatest cloud computing threat to enterprises is either insecure application programming interfaces (APIs) or shared technology vulnerabilities. This is not to minimize the five other threats, but these are threats we should already be familiar with because they are common to many other areas in information security. Insecure APIs or shared technology vulnerabilities are threats to traditional information security, but they become even greater threats in a cloud computing environment. This is because of the shared nature of the service and potential increased attack surface.
You can prevent cloud computing threats from causing harm to your organization by first investigating what potential vendors use for security controls and doing a risk assessment as recommended by the Cloud Security Alliance and HP. You can minimize the risk of insecure application programming interfaces by strictly configuring the access control for utilizing the API and by closely monitoring your access logs. You can lessen the risk from shared technology vulnerabilities by using a service provider that minimizes the different customers on shared infrastructures, limiting the sensitive data stored with the provider or having the sensitive data stored on a higher security infrastructure.
