Which of the following technologies is used by hardware manufacturers, publishers, copyright holders and individuals to impose limitations on the usage of digital content and devices?
Correct Answer:
D
Digital rights management (DRM) is an access control technology used by hardware manufacturers, publishers, copyright holders and individuals to impose limitations on the usage of digital content and devices. It describes the technology that prevents the uses of digital content that were not desired or foreseen by the content provider. DRM does not refer to other forms of copy protection which can be circumvented without modifying the file or device, such as serial numbers or keyfiles. It can also refer to restrictions associated with specific instances of digital works or devices. Answer C is incorrect. Code signing is the process of digitally signing executables and scripts in order to confirm the software author, and guarantee that the code has not been altered or corrupted since it is signed by use of a cryptographic hash. Answer A is incorrect. A hypervisor is a virtualization technique that allows multiple operating systems (guests) to run concurrently on a host computer. It is also called the virtual machine monitor (VMM). The hypervisor provides a virtual operating platform to the guest operating systems and checks their execution process. It provides isolation to the host's resources. The hypervisor is installed on server hardware. Answer B is incorrect. Grid computing refers to the combination of computer resources from multiple administrative domains to achieve a common goal.
ISO 27003 is an information security standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Which of the following elements does this standard contain? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
ACEF
ISO 27003 is an information security standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It is entitled as "Information Technology - Security techniques - Information security management system implementation guidance". The ISO 27003 standard provides guidelines for implementing an ISMS (Information Security Management System). It mainly focuses upon the PDCA method along with establishing, implementing, reviewing, and improving the ISMS itself. The ISO 27003 standard contains the following elements: Introduction Scope Terms and Definitions CSFs (Critical success factors) Guidance on process approach Guidance on using PDCA Guidance on Plan Processes Guidance on Do Processes Guidance on Check Processes Guidance on Act Processes Inter-Organization Co-operation Answer B is incorrect. This element is included in the ISO 27005 standard. Answer D is incorrect. This element is included in the ISO 27006 standard.
The NIST ITL Cloud Research Team defines some primary and secondary technologies as the fundamental elements of cloud computing in its "Effectively and Securely Using the Cloud Computing Paradigm" presentation. Which of the following technologies are included in the primary technologies? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
BCD
The primary technologies defined by the NIST ITL Cloud Research Team in its "Effectively and Securely Using the Cloud Computing Paradigm" presentation are as follows: Virtualization Grid technology SOA (Service Oriented Architecture) Distributed computing Broadband network Browser as a platform Free and open source software Answer A is incorrect. It is defined as the secondary technology.
Which of the following testing methods tests the system efficiency by systematically selecting the suitable and minimum set of tests that are required to effectively cover the affected changes?
Correct Answer:
D
Regression testing focuses on finding defects after a major code change has occurred. Specifically, it seeks to uncover software regressions, or old bugs that have come back. Such regressions occur whenever software functionality that was previously working correctly stops working as intended. Typically, regressions occur as an unintended consequence of program changes, when the newly developed part of the software collides with the previously existing code. Regression testing tests the system efficiency by systematically selecting the suitable and minimum set of tests that are required to effectively cover the affected changes. Answer A is incorrect. Unit testing is a type of testing in which each independent unit of an application is tested separately. During unit testing, a developer takes the smallest unit of an application, isolates it from the rest of the application code, and tests it to determine whether it works as expected. Unit testing is performed before integrating these independent units into modules. The most common approach to unit testing requires drivers and stubs to be written. Drivers and stubs are programs. A driver simulates a calling unit, and a stub simulates a called unit. Answer C is incorrect. Acceptance testing is performed on the application before its implementation into the production environment. It is done either by a client or an application specialist to ensure that the software meets the requirement for which it was made. Answer B is incorrect. Integration testing is a software testing that seeks to verify the interfaces between components against a software design. Software components may be integrated in an iterative way or all together ("big bang"). Normally the former is considered a better practice since it allows interface issues to be localized more quickly and fixed. Integration testing works to expose defects in the interfaces and interaction between the integrated components (modules). Progressively larger groups of tested software components corresponding to elements of the architectural design are integrated and tested until the software works as a system.
Security Test and Evaluation (ST&E) is a component of risk assessment. It is useful in discovering system vulnerabilities. For what purposes is ST&E used? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
BCD
Security Test and Evaluation (ST&E) is a component of risk assessment. It is useful in discovering system vulnerabilities. According to NIST SP 800-42 (Guideline on Network Security Testing), ST&E is used for the following purposes: To assess the degree of consistency between the system documentation and its implementation To determine the adequacy of security mechanisms, assurances, and other properties to enforce the security policy To uncover design, implementation, and operational flaws that may allow the violation of security policy Answer A is incorrect. ST&E is not used for the implementation of the system architecture.
