The goal of the Cloud Data Security domain is to inform you of the types of controls necessary to administer various levels of availability, integrity, and confidentiality (AIC) to secure data in the cloud.
You will gain knowledge on topics of data discovery and classification techniques; digital rights management; privacy of data; data retention, deletion, and archiving; data event logging, chain of custody and nonrepudiation; and the strategic use of security information and event management.
After completing this domain, you will be able to do the following:
Data security is a core element of cloud security (Figure 2.1). Cloud service providers (CSPs) often share the responsibility for security with the customer.
Roles such as the chief information security officer (CISO), chief security officer (CSO), chief technology officer (CTO), enterprise architect, and network administrator may all play a part in providing elements of a security solution for the enterprise.
The data security lifecycle, as introduced by the Securosis Blog and then incorporated into the CSA guidance, enables the organization to map the different phases in the data lifecycle against the required controls that are relevant to each phase.1
The lifecycle contains the following steps:
Not all implementations or situations align fully or comprehensively
