DRAG DROP Drop the appropriate value to complete the formula. Select and Place:
Correct Answer:
Explanation/Reference: Explanation: A Single Loss Expectancy (SLE) is the value in dollar ($) that is assigned to a single event. The SLE can be calculated by the following formula: SLE = Asset Value ($) X Exposure Factor (EF) The Exposure Factor (EF) represents the % of assets loss caused by a threat. The EF is required to calculate the Single Loss Expectancy (SLE). The Annualized Loss Expectancy (ALE) can be calculated by multiplying the Single Loss Expectancy (SLE) with the Annualized Rate of Occurrence (ARO). Annualized Loss Expectancy (ALE) = Single Loss Expectancy (SLE) X Annualized Rate of Occurrence (ARO) Annualized Rate of Occurrence (ARO) is a number that represents the estimated frequency in which a threat is expected to occur. It is calculated based upon the probability of the event occurring and the number of employees that could make that event occur.
Question 47
Which of the following methods is a means of ensuring that system changes are approved before being implemented, only the proposed and approved changes are implemented, and the implementation is complete and accurate?
Correct Answer: B
Explanation/Reference: Explanation: Documentation control is a method of ensuring that system changes should be agreed upon before being implemented, only the proposed and approved changes are implemented, and the implementation is complete and accurate. Documentation control is involved in the strict events for proposing, monitoring, and approving system changes and their implementation. It helps the change process by supporting the person who synchronizes the analytical task, approves system changes, reviews the implementation of changes, and oversees other tasks such as documenting the controls. AnswerD is incorrect. Configuration auditing is the quality assurance element of configuration management. It is occupied in the process of periodic checks to establish the consistency and completeness of accounting information and to validate that all configuration management policies are being followed. Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation. AnswerA is incorrect. Configuration control is a procedure of the Configuration management. Configuration control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. It supports the change of the functional and physical attributes of software at various points in time, and performs systematic control of changes to the identified attributes. Answer C is incorrect. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/ or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. Baselining an attribute forces formal configuration change control processes to be effected in the event that these attributes are changed.
Question 48
Which of the following is a standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system?
Correct Answer: C
Trusted Computer System Evaluation Criteria (TCSEC) is a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system. TCSEC was used to evaluate, classify, and select computer systems being considered for the processing, storage, and retrieval of sensitive or classified information. It was replaced with the development of the Common Criteria international standard originally published in 2005. The TCSEC, frequently referred to as the Orange Book, is the centerpiece of the DoD Rainbow Series publications. Answer D 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. Answer A is incorrect. FITSAF stands for Federal Information Technology Security Assessment Framework. It is a methodology for assessing the security of information systems. It provides an approach for federal agencies. It determines how federal agencies are meeting existing policy and establish goals. The main advantage of FITSAF is that it addresses the requirements of Office of Management and Budget (OMB). It also addresses the guidelines provided by the National Institute of Standards and Technology (NIsT). Answer B is incorrect. The Federal Information Processing Standards (FIPS) are publicly announced standards developed by the United States federal government for use by all non-military government agencies and by government contractors. Many FIPS standards are modified versions of standards used in the wider community (ANSI, IEEE, ISO, etc.). Some FIPS standards were originally developed by the U.S. government. For instance, standards for encoding data (e.g., country codes), but more significantly some encryption standards, such as the Data Encryption Standard (FIPS 46-3) and the Advanced Encryption Standard (FIPS 197). In 1994, NOAA (Noaa) began broadcasting coded signals called FIPS (Federal Information Processing System) codes along with their standard weather broadcasts from local stations. These codes identify the type of emergency and the specific geographic area (such as a county) affected by the emergency.
Question 49
You work as a security engineer for BlueWell Inc. You want to use some techniques and procedures to verify the effectiveness of security controls in Federal Information System. Which of the following NIST documents will guide you?
Correct Answer: C
NIST has developed a suite of documents for conducting Certification & Accreditation (C&A). These documents are as follows: 1.NIST Special Publication 800-37: This document is a guide for the security certification and accreditation of Federal Information Systems. 2.NIST Special Publication 800-53: This document provides a guideline for security controls for Federal Information Systems. 3.NIST Special Publication 800-53A. This document consists of techniques and procedures for verifying the effectiveness of security controls in Federal Information System. 4.NIST Special Publication 800-59: This document provides a guideline for identifying an information system as a National Security System. 5.NIST Special Publication 800 60: This document is a guide for mapping types of information and information systems to security objectives and risk levels.
Question 50
What are the various activities performed in the planning phase of the Software Assurance Acquisition process? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer: A,C,D
Explanation/Reference: Explanation: The various activities performed in the planning phase of the Software Assurance Acquisition process are as follows: Determine software product or service requirements. Identify associated risks. Develop software requirements. Create acquisition strategy. Develop evaluation criteria and evaluation plan. Define development and use of SwA due diligence questionnaires. Answer: B is incorrect. This activity is performed in the monitoring and acceptance phase of the Software Assurance acquisition process.
