CSSLP Online Practice Questions and Answers

Correct Answer:

The various principle documents of transformation are as follows: CNSSP 22: It establishes a national risk management policy for national security systems. CNSSI 1199: It creates the technique in which the national security community classifies the information and information systems with regard to confidentiality, integrity, and availability. CNSSI 1253: It combines DCID 6/3, DOD Instructions 8500.2, NIST SP 800-53, and other security sources into a single cohesive repository of security controls. CNSSI 1253 A. It offers the techniques to assess adequacy of each security control. CNSSI 1260: It provides guidance to organizations with the characterization of their information and information systems. NIST 800-37, Revision 1: It defines the certification and accreditation (C and A) process. The NIST 800-37, Revision 1 is a combination of DNI, DoD, and NIST.

Correct Answer: A

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 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 not the best answer for the question as historical information is not always available (consider new projects). Answer: D is incorrect. Quantitative risk analysis is in-depth and often requires a schedule and budget for the analysis. Answer: C is incorrect. Rolling wave planning is not a valid answer for risk analysis processes.

Correct Answer: ABDF

The public or commercial data classification is also built upon a four-level model, which are as follows: Public Sensitive Private Confidential Each level (top to bottom) represents an increasing level of sensitivity. The public level is similar to unclassified level military classification system. This level of data should not cause any damage if disclosed. Sensitive is a higher level of classification than public level data. This level of data requires a greater level of protection to maintain confidentiality. The Private level of data is intended for company use only. Disclosure of this level of data can damage the company. The Confidential level of data is considered very sensitive and is intended for internal use only. Disclosure of this level of data can cause serious damage to the company. Answer: C and E are incorrect. Unclassified and secret are the levels of military data classification.

Correct Answer: B

Malicious file execution is a vulnerability that occurs when an application directly uses or concatenates potentially hostile input with data file or stream functions. This leads to arbitrary remote and hostile data being included, processed, and invoked by the Web server. Malicious file execution can be prevented by using an indirect object reference map, input validation, or explicit taint checking mechanism. Answer: D is incorrect. Injection flaw occurs when data is sent to an interpreter as a part of command or query. Answer: A is incorrect. Insecure cryptographic storage occurs when applications have failed to encrypt data. Answer: C is incorrect. Insecure communication occurs when applications have failed to encrypt network traffic.

Correct Answer: B

Non-repudiation is a mechanism which proves that the sender really sent a message. It provides an evidence of the identity of the senderand message integrity. It also prevents a person from denying the submission or delivery of the message and the integrity of its contents. Answer: C is incorrect. Authentication is a process of verifying the identity of a person or network host. Answer: A is incorrect. Confidentiality ensures that no one can read a message except the intended receiver. Answer: D is incorrect. Integrity assures the receiver that the received message has not been altered in any way from the original.

Correct Answer: A

Integrity refers to the ability to ensure that the data is not modified or tampered with. Integrity means that data cannot be modified without authorization. Integrity is violated when an employee accidentally or with malicious intent deletes important data files, when a computer virus infects a computer, when an employee is able to modify his own salary in a payroll database, when an unauthorized user vandalizes a Web site, when someone is able to cast a very large number of votes in an online poll, and so on. Answer: D is incorrect. Confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems. Breaches of confidentiality take many forms. Permitting someone to look over your shoulder at your computer screen while you have confidential data displayed on it could be a breach of confidentiality. If a laptop computer containing sensitive information about a company's employees is stolen or sold, it could result in a breach of confidentiality. Answer: B is incorrect. Availability means that data must be available whenever it is needed. Answer: C is incorrect. Non-repudiation is the concept of ensuring that a party in a dispute cannot refuse to acknowledge, or refute the validity of a statement or contract. As a service, it provides proof of the integrity and origin of data. Although this concept can be applied to any transmission, including television and radio, by far the most common application is in the verification and trust of signatures.

Correct Answer: BCD

A Chief Information Officer (CIO) plays the role of a leader. The responsibilities of a Chief Information Officer are as follows: Establishes effective continuous monitoring program for the organization. Facilitates continuous monitoring process for the organizations. Preserves high- level communications and working group relationships in an organization. Confirms that information systems are covered by a permitted security plan and monitored throughout the System Development Life Cycle (SDLC). Manages and delegates decisions to employees in large enterprises. Proposes the information technology needed by an enterprise to achieve its goals and then works within a budget to implement the plan. Answer: A is incorrect. A Risk Executive facilitates the sharing of security risk-related information among authorizing officials.

Correct Answer: CD

Top-Down Approach is an approach to build a security program. The initiation, support, and direction come from the top management and work their way through middle management and then to staff members. It is treated as the best approach. This approach ensures that the senior management, who is ultimately responsible for protecting the company assets, is driving the program. Bottom-Up Approach is an approach to build a security program. The lower- end team comes up with a security control or a program without proper management support and direction. It is less effective and doomed to fail. Answer: A and B are incorrect. No such types of approaches exist

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.

Correct Answer: C

The credit card issuing company has violated the Privacy law. According to the Internet Privacy law, a company cannot provide their customer's financial and personal details to other companies. Answer: A is incorrect. Trademark laws facilitate the protection of trademarks around the world. Answer: B is incorrect. There is no law such as Security law. Answer: D is incorrect. The Copyright law protects original works or creations of authorship including literary, dramatic, musical, artistic, and certain other intellectual works.
