In digital rights management, the level of robustness depends on the various types of tools and attacks to which they must be resistant or immune. Which of the following types of tools are expensive, require skill, and are not easily available?
Correct Answer:
D
The tools used in DRM to define the level of robustness are as follows: 1.Widely available tools: These tools are easy to use and are available to everyone. For example, screw-drivers and file editors. 2.Specialized tools: These tools require skill and are available at reasonable prices. For example, debuggers, decompilers, and memory scanners. 3.Professional tools: These tools are expensive, require skill, and are not easily available. For example, logic analyzers, circuit emulators, and chip disassembly systems.
You work as a CSO (Chief Security Officer) for Tech Perfect Inc. You want to perform the following tasks: Develop a risk-driven enterprise information security architecture. Deliver security infrastructure solutions that support critical business initiatives. Which of the following methods will you use to accomplish these tasks?
Correct Answer:
C
SABSA (Sherwood Applied Business Security Architecture) is a framework and methodology for Enterprise Security Architecture and Service Management. SABSA is a model and a methodology for developing risk-driven enterprise information security architectures and for delivering security infrastructure solutions that support critical business initiatives. The primary characteristic of the SABSA model is that everything must be derived from an analysis of the business requirements for security, especially those in which security has an enabling function through which new business opportunities can be developed and exploited. Answer B is incorrect. The service-oriented modeling framework (SOMF) is a service-oriented development life cycle methodology. It offers a number of modeling practices and disciplines that contribute to a successful service-oriented life cycle management and modeling. The service-oriented modeling framework illustrates the major elements that identify the "what to do" aspects of a service development scheme. Answer A is incorrect. The service-oriented modeling and architecture (SOMA) includes an analysis and design method that extends traditional object-oriented and component-based analysis and design methods to include concerns relevant to and supporting SOAnswer D is incorrect. The service-oriented architecture (SOA) is a flexible set of design principles used during the phases of systems development and integration.
Which of the following terms refers to the protection of data against unauthorized access?
Correct Answer:
D
Confidentiality is a term that refers to the protection of data against unauthorized access. Administrators can provide confidentiality by encrypting data. Symmetric encryption is a relatively fast encryption method. Hence, this method of encryption is best suited for encrypting large amounts of data such as files on a computer. Answer A is incorrect. Integrity ensures that no intentional or unintentional unauthorized modification is made to datAnswer B is incorrect. Auditing is used to track user accounts for file and object access, logon attempts, system shutdown etc. This enhances the security of the network. Before enabling auditing, the type of event to be audited should be specified in the Audit Policy in User Manager for Domains.
Which of the following describes a residual risk as the risk remaining after a risk mitigation has occurred?
Correct Answer:
A
DIACAP describes a residual risk as the risk remaining after a risk mitigation has occurred. The Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) is a process defined by the United States Department of Defense (DoD) for managing risk. DIACAP replaced the former process, known as DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process), in 2006. DoD Instruction (DoDI) 8510.01 establishes a standard DoD-wide process with a set of activities, general tasks, and a management structure to certify and accredit an Automated Information System (AIS) that will maintain the Information Assurance (IA) posture of the Defense Information Infrastructure (DII) throughout the system's life cycle.DIACAP applies to the acquisition, operation, and sustainment of any DoD system that collects, stores, transmits, or processes unclassified or classified information since December 1997. It identifies four phases: 1.System Definition 2.Verification 3.Validation 4.Re-Accreditation Answer D is incorrect. An Information System Security Officer (ISSO) plays the role of a supporter. The responsibilities of an Information System Security Officer (ISSO) are as follows: Manages the security of the information system that is slated for Certification & Accreditation (C&A). Insures the information systems configuration with the agency's information security policy. Supports the information system owner/information owner for the completion of security- related responsibilities. Takes part in the formal configuration management process. Prepares Certification & Accreditation (C&A) packages. Answer B is incorrect. The Designated Approving Authority (DAA), in the United States Department of Defense, is the official with the authority to formally assume responsibility for operating a system at an acceptable level of risk. The DAA is responsible for implementing system security. The DAA can grant the accreditation and can determine that the system's risks are not at an acceptable level and the system is not ready to be operational. Answer B is incorrect. System Security Authorization Agreement (SSAA) is an information security document used in the United States Department of Defense (DoD) to describe and accredit networks and systems. The SSAA is part of the Department of Defense Information Technology Security Certification and Accreditation Process, or DITSCAP (superseded by DIACAP). The DoD instruction (issues in December 1997, that describes DITSCAP and provides an outline for the SSAA document is DODI 5200.40. The DITSCAP application manual (DoD 8510.1-M), published in July 2000, provides additional details.
According to the NIST SAMATE, dynamic analysis tools operate by generating runtime vulnerability scenario using some functions. Which of the following are functions that are used by the dynamic analysis tools and are summarized in the NIST SAMATE? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
ACD
According to the NIST SAMATE, dynamic analysis tools operate by generating runtime vulnerability scenario using the following functions: Resource fault injection Network fault injection System fault injection User interface fault injection Design attack Implementation attack File corruption Answer B is incorrect. This function is summarized for static analysis tools.
