ISC CISSP Exam With Confidence Using Practice Dumps

 The discovery phase of a vulnerability assessment is the process of identifying and enumerating the hosts, services, and applications that are in scope of the assessment. This phase involves techniques such as network scanning, port scanning, service scanning, and banner grabbing. If one third of the hosts that were in scope are missing from the report, it means that the discovery phase was not performed properly or completely, and some hosts were not detected or included in the assessment. The enumeration, reporting, and detection phases are not likely to cause this error, as they depend on the results of the discovery phase. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7: Security Assessment and Testing, page 857; Official (ISC)2 Guide to the CISSP CBK, Fifth Edition, Chapter 6: Security Assessment and Testing, page 794.

Identity as a Service (IDaaS) is the best contract in offloading the task of account management from the IT staff. IDaaS is a cloud-based service that provides identity and access management (IAM) functions, such as user authentication, authorization, provisioning, deprovisioning, password management, single sign-on (SSO), and multifactor authentication (MFA). IDaaS can help the organization to streamline and automate the account management process, reduce the workload and costs of the IT staff, and improve the security and compliance of the user accounts. IDaaS can also support the contractors who have limited onsite time, as they can access the organization’s resources remotely and securely through the IDaaS provider.

The other options are not as effective as IDaaS in offloading the task of account management from the IT staff, as they do not provide IAM functions. Platform as a Service (PaaS) is a cloud-based service that provides a platform for developing, testing, and deploying applications, but it does not manage the user accounts for the applications. Desktop as a Service (DaaS) is a cloud-based service that provides virtual desktops for users to access applications and data, but it does not manage the user accounts for the virtual desktops. Software as a Service (SaaS) is a cloud-based service that provides software applications for users to use, but it does not manage the user accounts for the software applications.

 The Hardware Abstraction Layer (HAL) is implemented in the system software. The system software is the software that controls and manages the basic operations and functions of the computer system, such as the operating system, the device drivers, the firmware, and the BIOS. The HAL is a component of the system software that provides a common interface between the hardware and the software layers of the system. The HAL abstracts the details and differences of the hardware devices and components, and allows the software to interact with the hardware in a consistent and uniform way. The HAL also enables the system to support multiple hardware platforms and configurations without requiring changes in the software5 . References: 5: What is Hardware Abstraction Layer (HAL)? : Hardware Abstraction Layer (HAL) - GeeksforGeeks
