Correct Answer:
AB
The following types of software are safety critical software: Software that is used to apply a critical decision-making process Software that is used to manage or monitor safety critical functions Software that intervenes when an unsafe condition is present or is about to happen Software that executes on the same target system as safety critical software Software that impacts the systems on which safety critical software runs Software that manages safety critical data including display of safety critical information Software that is used to validate and verify safety critical software Answer D is incorrect. Software that is used to manage or monitor safety critical functions is known as safety critical software. Answer C is incorrect. Software that intervenes when an unsafe condition is present or is about to happen is known as safety critical software.

You work as a Network Auditor for XYZ CORP. The company has a Windows-based network. While auditing the company's network, you are facing problems in searching the faults and other entities that belong to it. Which of the following risks may occur due to the existence of these problems?
Correct Answer:
D
Detection risks are the risks that an auditor will not be able to find what they are looking to detect. Hence, it becomes tedious to report negative results when material conditions (faults) actually exist. Detection risk includes two types of risk: Sampling risk: This risk occurs when an auditor falsely accepts or erroneously rejects an audit sample. Nonsampling risk: This risk occurs when an auditor fails to detect a condition because of not applying the appropriate procedure or using procedures inconsistent with the audit objectives (detection faults). Answer A is incorrect. Residual risk is the risk or danger of an action or an event, a method or a (technical) process that, although being abreast with science, still conceives these dangers, even if all theoretically possible safety measures would be applied (scientifically conceivable measures). The formula to calculate residual risk is (inherent risk) x (control risk) where inherent risk is (threats vulnerability). In the economic context, residual means "the quantity left over at the end of a process; a remainder". Answer B is incorrect. Inherent risk, in auditing, is the risk that the account or section being audited is materially misstated without considering internal controls due to error or fraud. The assessment of inherent risk depends on the professional judgment of the auditor, and it is done after assessing the business environment of the entity being audited. Answer C is incorrect. A secondary risk is a risk that arises as a straight consequence of implementing a risk response. The secondary risk is an outcome of dealing with the original risk. Secondary risks are not as rigorous or important as primary risks, but can turn out to be so if not estimated and planned properly.
