Explanation:
The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. Platform-as-a-Service (PaaS) is a model of service delivery whereby the computing platform is provided as an on-demand service upon which applications can be developed and deployed. Its main purpose is to reduce the cost and complexity of buying, housing, and managing the underlying hardware and software components of the platform, including any needed program and database development tools. The development environment is typically special purpose, determined by the cloud provider and tailored to the design and architecture of its platform. The cloud consumer has control over applications and application environment settings of the platform. Security provisions are split between the cloud provider and the cloud consumer.
Incorrect Answers:
C: Software-as-a-Service (SaaS) is a model of service delivery whereby one or more applications and the computational resources to run them are provided for use on demand as a turnkey service. Its main purpose is to reduce the total cost of hardware and software development, maintenance, and operations.
Security provisions are carried out mainly by the cloud provider. The cloud consumer does not manage or control the underlying cloud infrastructure or individual applications, except for preference selections and limited administrative application settings.
D: Infrastructure-as-a-Service (IaaS) is a model of service delivery whereby the basic computing infrastructure of servers, software, and network equipment is provided as an on- demand service upon which a platform to develop and execute applications can be established. Its main purpose is to avoid purchasing, housing, and managing the basic hardware and software infrastructure components, and instead obtain those resources as virtualized objects controllable via a service interface. The cloud consumer generally has broad freedom to choose the operating system and development environment to be hosted. Security provisions beyond the basic infrastructure are carried out mainly by the cloud consumer
D: Code as a Service does not exist. There is no such service model.

Cloud Deployment Models
NOTE: WHAT IS A CLOUD INFRASTRUCTURE?
A cloud infrastructure is the collection of hardware and software that enables the five essential characteristics of cloud computing. The cloud infrastructure can be viewed as containing both a physical layer and an abstraction layer. The physical layer consists of the hardware resources that are necessary to support the cloud services being provided, and typically includes server, storage and network components.
The abstraction layer consists of the software deployed across the physical layer, which manifests the essential cloud characteristics. Conceptually the abstraction layer sits above the physical layer.

The correct answer is Trap door. Answer view refers to a mechanism in a database system that restricts access to certain information within the database. The view implements the principle of least privilege.
Answer Open door is a distracter, and answer Data diode refers to a mechanism usually in multilevel security systems that limits the flow of classified information to one direction.

Security continuous monitoring is the program in which it is most important to include the collection of security process data. Security process data is the data that reflects the performance, effectiveness, and compliance of the security processes, such as the security policies, standards, procedures, and guidelines.
Security process data can include metrics, indicators, logs, reports, and assessments. Security process data can provide several benefits, such as:
* Improving the security and risk management of the system by providing the visibility and awareness of the security posture, vulnerabilities, and threats
* Enhancing the security and decision making of the system by providing the evidence and information for the security analysis, evaluation, and reporting
* Increasing the security and improvement of the system by providing the feedback and input for the security response, remediation, and optimization Security continuous monitoring is the program in which it is most important to include the collection of security process data, because it is the program that involves maintaining the ongoing awareness of the security status, events, and activities of the system. Security continuous monitoring can enable the system to detect and respond to any security issues or incidents in a timely and effective manner, and to adjust and improve the security controls and processes accordingly. Security continuous monitoring can also help the system to comply with the security requirements and standards from the internal or external authorities or frameworks.
The other options are not the programs in which it is most important to include the collection of security process data, but rather programs that have other objectives or scopes. Quarterly access reviews are programs that involve reviewing and verifying the user accounts and access rights on a quarterly basis. Quarterly access reviews can ensure that the user accounts and access rights are valid, authorized, and up to date, and that any inactive, expired, or unauthorized accounts or rights are removed or revoked. However, quarterly access reviews are not the programs in which it is most important to include the collection of security process data, because they are not focused on the security status, events, and activities of the system, but rather on the user accounts and access rights. Business continuity testing is a program that involves testing and validating the business continuity plan (BCP) and the disaster recovery plan (DRP) of the system. Business continuity testing can ensure that the system can continue or resume its critical functions and operations in case of a disruption or disaster, and that the system can meet the recovery objectives and requirements. However, business continuity testing is not the program in which it is most important to include the collection of security process data, because it is not focused on the security status, events, and activities of the system, but rather on the continuity and recovery of the system. Annual security training is a program that involves providing and updating the security knowledge and skills of the system users and staff on an annual basis. Annual security training can increase the security awareness and competence of the system users and staff, and reduce the human errors or risks that might compromise the system security. However, annual security training is not the program in which it is most important to include the collection of security process data, because it is not focused on the security status, events, and activities of the system, but rather on the security education and training of the system users and staff.
