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. References :=

When auditing a public cloud, it is essential to review areas such as Identity and Access Management (IAM) and data protection. IAM involves ensuring that only authorized individuals have access to the cloud resources, and that their access is appropriately managed and monitored. This includes reviewing user authentication methods, access control policies, role-based access controls, and user activity monitoring1.

Data protection is another critical area to review. It involves ensuring that the data stored in the public cloud is secure from unauthorized access, breaches, and leaks. This includes reviewing data encryption methods, data backup and recovery processes, data privacy policies, and compliance with relevant data protection regulations1.

While the other options may also be relevant in certain contexts, they are not as universally applicable as IAM and data protection for auditing a public cloud. Source code reviews and hypervisor (option B), patching and configuration (option C), and vulnerability management and cybersecurity reviews (option D) are important but are more specific to certain types of cloud services or deployment models. References:

Continuous integration (CI) is the most critical concept for managing the building and testing of code in DevOps. CI is the practice of merging all developers’ working copies of code to a shared mainline several times a day. This enables early detection and resolution of bugs, conflicts, and errors, as well as faster and more frequent feedback loops. CI also facilitates the automation of building, testing, and deploying code, which improves the quality, reliability, and security of the software delivery process. CI is a prerequisite for continuous delivery (CD) and continuous deployment (CD), which are the next stages of DevOps maturity that aim to deliver software to customers faster and more frequently. References:
