You work as a Network Auditor for Net Perfect Inc. 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: 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 🗳️
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 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 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 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.

The National Information Assurance Certification and Accreditation Process (NIACAP) is the minimum standard process for the certification and accreditation of computer and telecommunications systems that handle U.S. national security information. Which of the following participants are required in a NIACAP security assessment? Each correct answer represents a part of the solution. Choose all that apply.

Correct Answer: process. Answer: D is incorrect. Information Assurance Manager (IAM) is one of the key participants in the DIACAP process. 🗳️
The NIACAP roles are nearly the same as the DITSCAP roles. Four minimum participants (roles) are required to perform a NIACAP security assessment: IS program manager: The IS program manager is the primary authorization advocate. He is responsible for the Information Systems (IS) throughout the life cycle of the system development. Designated Approving Authority (DAA): 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. Certification agent: The certification agent is also referred to as the certifier. He provides the technical expertise to conduct the certification throughout the system life cycle. User representative: The user representative focuses on system availability, access, integrity, functionality, performance, and confidentiality in a Certification and Accreditation (C&A)

Correct Answer:
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.

Which of the following penetration testing techniques automatically tests every phone line in an exchange and tries to locate modems that are attached to the network?

Correct Answer: Information about these modems can then be used to attempt external unauthorized access. Answer: B is incorrect. In sniffing, a protocol analyzer is used to 🗳️
The demon dialing technique automatically tests every phone line in an exchange and tries to locate modems that are attached to the network. most commonly used technique of all, getting information (like passwords) just by asking for them.

Which of the following roles is also known as the accreditor?

Correct Answer: D 🗳️

DoD 8500.2 establishes IA controls for information systems according to the Mission Assurance Categories (MAC) and confidentiality levels. Which of the following MAC levels requires high integrity and medium availability?

Correct Answer: D 🗳️
The various MAC levels are as follows: MAC I: It states that the systems have high availability and high integrity. MAC II: It states that the systems have high integrity and medium availability. MAC III: It states that the systems have basic integrity and availability.

Microsoft software security expert Michael Howard defines some heuristics for determining code review in "A Process for Performing Security Code Reviews".
Which of the following heuristics increase the application's attack surface? Each correct answer represents a complete solution. Choose all that apply.

Correct Answer: BDEF 🗳️
Microsoft software security expert Michael Howard defines the following heuristics for determining code review in "A Process for Performing Security
Code Reviews": Old code: Newer code provides better understanding of software security and has lesser number of vulnerabilities. Older code must be checked deeply. Code that runs by default: It must have high quality, and must be checked deeply than code that does not execute by default. Code that runs by default increases the application's attack surface.
Code that runs in elevated context: It must have higher quality. Code that runs in elevated privileges must be checked deeply and increases the application's attack surface. Anonymously accessible code: It must be checked deeply than code that only authorized users and administrators can access, and it increases the application's attack surface. Code listening on a globally accessible network interface: It must be checked deeply for security vulnerabilities and increases the application's attack surface. Code written in C/C++/assembly language: It is prone to security vulnerabilities, for example, buffer overruns. Code with a history of security vulnerabilities: It includes additional vulnerabilities except concerted efforts that are required for removing them. Code that handles sensitive data: It must be checked deeply to ensure that data is protected from unintentional disclosure. Complex code: It includes undiscovered errors because it is more difficult to analyze complex code manually and programmatically. Code that changes frequently: It has more security vulnerabilities than code that does not change frequently.

Which of the following cryptographic system services ensures that information will not be disclosed to any unauthorized person on a local network?

Correct Answer: D 🗳️
The confidentiality service of a cryptographic system ensures that information will not be disclosed to any unauthorized person on a local network.

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: ACD 🗳️

You work as a project manager for BlueWell Inc. You are working on a project and the management wants a rapid and cost-effective means for establishing priorities for planning risk responses in your project. Which risk management process can satisfy management's objective for your project?

Correct Answer: Project Scope Statement Risk Management Plan Risk Register Answer: B is incorrect. Historical information can be helpful in the qualitative risk analysis, but it is 🗳️
Qualitative risk analysis is the best answer as it is a fast and low-cost approach to analyze the risk impact and its effect. It can promote certain risks onto risk response planning. Qualitative Risk Analysis uses the likelihood and impact of the identified risks in a fast and cost-effective manner. Qualitative Risk
Analysis establishes a basis for a focused quantitative analysis or Risk Response Plan by evaluating the precedence of risks with a concern to impact on the project's scope, cost, schedule, and quality objectives. The qualitative risk analysis is conducted at any point in a project life cycle. The primary goal of qualitative risk analysis is to determine proportion of effect and theoretical response. The inputs to the Qualitative Risk Analysis process are: Organizational process assets
