Controls mapping found in the Scope Applicability column of the Cloud Controls Matrix (CCM) may help organizations to realize cost savings by avoiding duplication of efforts in the compliance evaluation and for the eventual control design and implementation. The Scope Applicability column is a feature of the CCM that indicates which cloud model type (IaaS, PaaS, SaaS) or cloud environment (public, hybrid, private) a control applies to. This feature can help organizations to identify and select the most relevant and appropriate controls for their specific cloud scenario, as well as to map them to multiple industry-accepted security standards, regulations, and frameworks. By doing so, organizations can reduce the time, resources, and costs involved in achieving and maintaining compliance with various cloud security requirements123.
The other options are not directly related to the question. Option B, by implementing layered security, thus reducing the likelihood of data breaches and the associated costs, is not a valid reason because layered security is a general principle of defense in depth, not a specific feature of the CCM or the Scope Applicability column. Option C, by avoiding the need to hire a cloud security specialist to perform the periodic risk assessment exercise, is not a valid reason because using the CCM or the Scope Applicability column does not eliminate the need for a cloud security specialist or a periodic risk assessment exercise, which are essential for ensuring the effectiveness and adequacy of the cloud security controls. Option D, by avoiding fines for breaching those regulations that impose a controls mapping in order to prove compliance, is not a valid reason because controls mapping is not a mandatory requirement for proving compliance, but a voluntary tool for facilitating compliance.
