WGU, Information Security and Assurance (C725), SET I Information security is primarily a discipline to manage the behavior of _____. A. Technology B. People C. Processes D. Organizations - ✔� ... ��People Careers in information security are booming because of which of the following factors? A. Threats of cyberterrorism B. Government regulations C. Growth of the Internet D. All of these - ✔✔All of these A program for information security should include which of the following elements? A. Security policies and procedures B. Intentional attacks only C. Unintentional attacks only D. None of these - ✔✔Security policies and proceduresExplanation: Answer A is correct. The Carnegie Melon Information Network Institute (INI) designed programs to carry out multiple tasks including Information Security Policies. The growing demand for InfoSec specialists is occurring predominantly in which of the following types of organizations? A. Government B. Corporations C. Not-for-profit foundations D. All of these - ✔✔D. All of these The concept of the measures used to ensure the protection of the secrecy of data, objects, or resources. - ✔✔Confidentiality A catchall safe rating for any box with a lock on it. This rating describes the thickness of the steel used to make the lockbox. No actual testing is performed to gain this rating. - ✔✔B-Rate Safe Rating This safe rating is defined as a variably thick steel box with a 1-inch-thick door and a lock. No tests are conducted to provide this rating, either. - ✔✔C-Rate Safe Rating Safes with an Underwriters Laboratory rating that have passed standardized tests as defined in Underwriters Laboratory Standard 687 using tools and an expert group ofsafe-testing engineers. The safe rating label requires that the safe be constructed of 1- inch solid steel or equivalent. The label means that the safe has been tested for a net working time of 15 minutes using "common hand tools, drills, punches hammers, and pressure applying devices." Net working time means that when the tool comes off the safe, the clock stops. Engineers exercise more than 50 different types of attacks that have proven effective for safecracking. - ✔✔UL TL-15 Safe Rating This Underwriters Laboratory rating testing is essentially the same as the TL-15 testing, except for the net working time. Testers get 30 minutes and a few more tools to help them gain access. Testing engineers usually have a safe's manufacturing blueprints and can disassemble the safe before the test begins to see how it works. - ✔✔UL TL-30 Safe Rating Related to information security, confidentiality is the opposite of which of the following? A. Closure B. Disclosure C. Disaster D. Disposal - ✔✔B. Disclosure Explanation: Confidentiality models are primarily intended to ensure that no unauthorized access to information is permitted and that accidental disclosure of sensitive information is not possible. Integrity models have which of the three goals: A. Prevent unauthorized users from making modifications to data or programs B. Prevent authorized users from making improper or unauthorized modifications C. Maintain internal and external consistency of data and programs D. All of these - ✔✔D. All of these Explanation: Integrity models keep data pure and trustworthy by protecting system data from intentional or accidental changes. Information security professionals usually address which of these three common challenges to availability: A. Denial of service (DoS) due to intentional attacks or because of undiscovered flaws in implementation (for example, a program written by a programmer who is unaware of a flaw that could crash the program if a certain unexpected input is encountered) B. Loss of information system capabilities because of natural disasters (fires, floods, storms, or earthquakes) or human actions (bombs or strikes) C. Equipment failures during normal use. D. All of these - ✔✔D. All of theseExplanation:Availability models keep data and resources available for authorized use, especially during emergencies or disasters. Which of the following represents the three goals of information security? A. Confidentiality, integrity, and availability B. Prevention, detection, and responseC. People controls, process controls, and technology controls D. Network security, PC security, and mainframe security - ✔✔A. Confidentiality, integrity, and availabilityExplanation:These goals form the confidentiality, integrity, availability (CIA) triad, the basis of all security programs. Usually a documented argument or stated position in order to define a need to make a decision or take some form of action. - ✔✔Business Case A type of security management planning where upper, or senior, management is responsible for initiating and defining policies for the organization. - ✔✔Top-down approach A type of security management planning where IT staff makes security decisions directly without input from senior management. This approach is rarely used in organizations and is considered problematic in the IT industry. - ✔✔Bottom-up approach This security plan is a long-term plan that is fairly stable. It defines the organization's security purpose. It also helps to understand security function and align it to the goals, mission, and objectives of the organization. It's useful for about five years if it is maintained and updated annually. This plan also serves as the planning horizon. Longterm goals and visions for the future are discussed this plan. Thisplan should include a risk assessment. - ✔✔Strategic Plan This security plan is a midterm plan developed to provide more details on accomplishing the goals set forth in the strategic plan or can be crafted ad hoc based upon unpredicted events. This plan is typically useful for about a year and often prescribes and schedules the tasks necessary to accomplish organizational goals. Some examples of these plans are project plans, acquisition plans, hiring plans, budget plans, maintenance plans, support plans, and system development plans. - ✔✔Tactical Plan This security plan is a short-term, highly detailed plan based on the strategic and tactical plans. It is valid or useful only for a short time. These plans must be updated often (such as monthly or quarterly) to retain compliance with tactical plans. These plans spell out how to accomplish the various goals of the organization. They include resource allotments, budgetary requirements, staffing assignments, scheduling, and step-by-step or implementation procedures. These plans include details on how the implementation processes are in compliance with the organization's security policy. Examples of these plans are training plans, system deployment plans, and product design plans. - ✔✔Operational Plan Also called classification, the primary means by which data is protected based on its need for secrecy, sensitivity, or confidentiality. It is the process of organizing items, objects, subjects, and so on into groups, categories, or collections with similarities. - ✔✔Data classification [Show More]
