Question # 1
In which of the following levels of exception safety are operations succeeded with fullguarantee and fulfill all needs in the presence of exceptional situations?
A. Commit or rollback semantics B. Minimal exception safety C. Failure transparency D. Basic exception safety
Answer: C
Explanation: Failure transparency is the best level of exception safety. In this level,
operations are succeeded with full guarantee and fulfill all needs in the presence of
exceptional situations. Failure transparency does not throw the exception further up even
when an exception occurs. This level is also known as no throw guarantee.

A. It modifies the implementation of a component without affecting the specifications of theinterface. B. It controls the accessing of a component. C. It displays the implementation details of a component. D. It provides a programmatic way of communication between the components that areworking with different programming languages.
Answer: A,B,D
Explanation: The benefits of a software interface are as follows: It provides a
programmatic way of communication between the components that are working with
different programming languages. It prevents direct communication between components.
It modifies the implementation of a component without affecting the specifications of the
interface. It hides the implementation details of a component. It controls the accessing of a
component. Answer: C is incorrect. A software interface hides the implementation details of
the component
Question # 4
Fill in the blank with an appropriate security type. applies the internal security policies of thesoftware applications when they are deployed.
A. Programmatic security
Answer: A
Explanation: Programmatic security applies the internal security policies of the software
applications when they are deployed. In this type of security, the code of the software
application controls the security behavior, and authentication decisions are made based on
the business logic, such as the user role or the task performed by the user in a specific
security context.
Question # 5
Fill in the blank with an appropriate security type. applies the internal security policies of thesoftware applications when they are deployed.
A. Programmatic security
Answer: A
Explanation: Programmatic security applies the internal security policies of the software
applications when they are deployed. In this type of security, the code of the software
application controls the security behavior, and authentication decisions are made based on
the business logic, such as the user role or the task performed by the user in a specific
security context.
Question # 6
Audit trail or audit log is a chronological sequence of audit records, each of which containsevidence directly pertaining to and resulting from the execution of a business process orsystem function. Under which of the following controls does audit control come?
A. Reactive controls B. Detective controls C. Protective controls D. Preventive controls
Answer: B
Explanation: Audit trail or audit log comes under detective controls. Detective controls are
the audit controls that are not needed to be restricted. Any control that performs a
monitoring activity can likely be defined as a Detective Control. For example, it is possible
that mistakes, either intentional or unintentional, can be made. Therefore, an additional
Protective control is that these companies must have their financial results audited by an
independent Certified Public Accountant. The role of this accountant is to act as an auditor.
In fact, any auditor acts as a Detective control. If the organization in question has not
properly followed the rules, a diligent auditor should be able to detect the deficiency which
indicates that some control somewhere has failed. Answer: A is incorrect. Reactive or
corrective controls typically work in response to a detective control, responding in such a
way as to alert or otherwise correct an unacceptable condition. Using the example of
account rules, either the internal Audit Committee or the SEC itself, based on the report
generated by the external auditor, will take some corrective action. In this way, they are
acting as a Corrective or Reactive control. Answer: C and D are incorrect. Protective or
preventative controls serve to proactively define and possibly enforce acceptable
behaviors. As an example, a set of common accounting rules are defined and must be
followed by any publicly traded company. Each quarter, any particular company must
publicly state its current financial standing and accounting as reflected by an application of
these rules. These accounting rules and the SEC requirements serve as protective or
preventative controls.
Question # 7
Which of the following concepts represent the three fundamental principles of informationsecurity? Each correct answer represents a complete solution. Choose three.
A. Privacy B. Availability C. Integrity D. Confidentiality
Answer: B,C,D
Explanation: The following concepts represent the three fundamental principles of
information security: 1.Confidentiality 2.Integrity 3.Availability Answer: B is incorrect.
Privacy, authentication, accountability, authorization and identification are also concepts
related to information security, but they do not represent the fundamental principles of
information security.
Question # 8
Which of the following DoD policies establishes policies and assigns responsibilities toachieve DoD IA through a defense-in-depth approach that integrates the capabilities ofpersonnel, operations, and technology, and supports the evolution to network-centricwarfare?
A. DoDI 5200.40 B. DoD 8500.1 Information Assurance (IA) C. DoD 8510.1-M DITSCAP D. DoD 8500.2 Information Assurance Implementation
Answer: B
Explanation: DoD 8500.1 Information Assurance (IA) sets up policies and allots
responsibilities to achieve DoD IA through a defense-in-depth approach that integrates the
capabilities of personnel, operations, and technology, and supports the evolution to
network-centric warfare. DoD 8500.1 also summarizes the roles and responsibilities for the
persons responsible for carrying out the IA policies. Answer: D is incorrect. The DoD
8500.2 Information Assurance Implementation pursues 8500.1. It provides assistance on
how to implement policy, assigns responsibilities, and prescribes procedures for applying
integrated, layered protection of the DoD information systems and networks. DoD
Instruction 8500.2 allots tasks and sets procedures for applying integrated layered
protection of the DOD information systems and networks in accordance with the DoD
8500.1 policy. It also provides some important guidelines on how to implement an IA
program. Answer: A is incorrect. DoDI 5200.40 executes the policy, assigns
responsibilities, and recommends procedures under reference for Certification and
Accreditation(C&A) of information technology (IT). Answer: C is incorrect. DoD 8510.1-M
DITSCAP provides standardized activities leading to accreditation, and establishes a process and management baseline.
Question # 9
Shoulder surfing is a type of in-person attack in which the attacker gathers informationabout the premises of an organization. This attack is often performed by lookingsurreptitiously at the keyboard of an employee's computer while he is typing in hispassword at any access point such as a terminal/Web site. Which of the following isviolated in a shoulder surfing attack?
A. Integrity B. Availability C. Confidentiality D. Authenticity
Answer: C
Explanation: Confidentiality is violated in a shoulder surfing attack. The CIA triad provides
the following three tenets for which security practices are measured: Confidentiality: It 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.
Integrity: It 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. Availability: It means that
data must be available at every time when it is needed. Answer: D is incorrect. Authenticity
is not a tenet of the CIA triad.
Question # 10
You work as a Security Manager for Tech Perfect Inc. You want to save all the data fromthe SQL injection attack, which can read sensitive data from the database and modifydatabase data using some commands, such as Insert, Update, and Delete. Which of thefollowing tasks will you perform? Each correct answer represents a complete solution.Choose three.
A. Apply maximum number of database permissions. B. Use an encapsulated library for accessing databases. C. Create parameterized stored procedures. D. Create parameterized queries by using bound and typed parameters.
Answer: B,C,D
Explanation: The methods of mitigating SQL injection attacks are as follows: 1.Create
parameterized queries by using bound and typed parameters. 2.Create parameterized
stored procedures. 3.Use a encapsulated library in order to access databases. 4.Minimize
database permissions. Answer: A is incorrect. In order to save all the data from the SQL
injection attack, you should minimize database permissions.
Question # 11
A part of a project deals with the hardware work. As a project manager, you have decidedto hire a company to deal with all hardware work on the project. Which type of riskresponse is this?
A. Exploit B. Mitigation C. Transference D. Avoidance
Answer: C
Explanation: When you are hiring a third party to own risk, it is known as transference risk
response. Transference is a strategy to mitigate negative risks or threats. In this strategy,
consequences and the ownership of a risk is transferred to a third party. This strategy does
not eliminate the risk but transfers responsibility of managing the risk to another party.
Insurance is an example of transference. Answer: B is incorrect. The act of spending
money to reduce a risk probability and impact is known as mitigation. Answer: A is
incorrect. Exploit is a strategy that may be selected for risks with positive impacts where
the organization wishes to ensure that the opportunity is realized. Answer: D is incorrect.
When extra activities are introduced into the project to avoid the risk, this is an example of
avoidance.
Question # 12
Which of the following statements about the integrity concept of information securitymanagement are true? Each correct answer represents a complete solution. Choose three.
A. It ensures that unauthorized modifications are not made to data by authorized personnelor processes. B. It determines the actions and behaviors of a single individual within a system C. It ensures that internal information is consistent among all subentities and alsoconsistent with the real-world, external situation. D. It ensures that modifications are not made to data by unauthorized personnel orprocesses.
Answer: A,C,D
Explanation: The following statements about the integrity concept of information security
management are true: It ensures that modifications are not made to data by unauthorized
personnel or processes. It ensures that unauthorized modifications are not made to data by
authorized personnel or processes. It ensures that internal information is consistent among
all subentities and also consistent with the real-world, external situation. Answer: B is
incorrect. Accountability determines the actions and behaviors of an individual within a
system, and identifies that particular individual. Audit trails and logs support accountability.
Question # 13
You work as a security manager for BlueWell Inc. You are performing the externalvulnerability testing, or penetration testing to get a better snapshot of your organization'ssecurity posture. Which of the following penetration testing techniques will you use forsearching paper disposal areas for unshredded or otherwise improperly disposed-ofreports?
A. Sniffing B. Scanning and probing C. Dumpster diving D. Demon dialing
Answer: C
Explanation: Dumpster diving technique is used for searching paper disposal areas for
unshredded or otherwise improperly disposed-of reports. Answer: B is incorrect. In
scanning and probing technique, various scanners, like a port scanner, can reveal
information about a network's infrastructure and enable an intruder to access the network's
unsecured ports. Answer: D is incorrect. Demon dialing technique automatically tests every
phone line in an exchange to try to locate modems that are attached to the network.
Answer: A is incorrect. In sniffing technique, protocol analyzer can be used to capture data
packets that are later decoded to collect information such as passwords or infrastructure
configurations.
Question # 14
Which of the following models manages the software development process if thedevelopers are limited to go back only one stage to rework?
A. Waterfall model B. Spiral model C. RAD model D. Prototyping model
Answer: A
Explanation: In the waterfall model, software development can be managed if the
developers are limited to go back only one stage to rework. If this limitation is not imposed
mainly on a large project with several team members, then any developer can be working
on any phase at any time, and the required rework might be accomplished several times.
Answer: B is incorrect. The spiral model is a software development process combining
elements of both design and prototyping-in- stages, in an effort to combine advantages of
top-down and bottom-up concepts. The basic principles of the spiral model are as follows:
The focus is on risk assessment and minimizing project risks by breaking a project into
smaller segments and providing more ease-of- change during the development process, as
well as providing the opportunity to evaluate risks and weigh consideration of project
continuation throughout the life cycle. Each cycle involves a progression through the same
sequence of steps, for each portion of the product and for each of its levels of elaboration,
from an overall concept-of-operation document down to the coding of each individual
program. Each trip around the spiral traverses the following four basic quadrants:
Determine objectives, alternatives, and constraints of the iteration. Evaluate alternatives,
and identify and resolve risks. Develop and verify deliverables from the iteration. Plan the
next iteration.
Begin each cycle with an identification of stakeholders and their win conditions, and end
each cycle with review and commitment. Answer: D is incorrect. The Prototyping model is a
systems development method (SDM). In this model, a prototype is created, tested, and
then reworked as necessary until an adequate prototype is finally achieved from which the
complete system or product can now be developed. Answer: C is incorrect. Rapid
Application Development (RAD) refers to a type of software development methodology that
uses minimal planning in favor of rapid prototyping.
Question # 15
Which of the following is NOT a responsibility of a data owner?
A. Approving access requests B. Ensuring that the necessary security controls are in place C. Delegating responsibility of the day-to-day maintenance of the data protectionmechanisms to the data custodian D. Maintaining and protecting data
Answer: D
Explanation: It is not a responsibility of a data owner. The data custodian (information
custodian) is responsible for maintaining and protecting the data.
Answer: B, A, and C are incorrect. All of these are responsibilities of a data owner. The
roles and responsibilities of a data owner are as follows: The data owner (information
owner) is usually a member of management, in charge of a specific business unit, and is
ultimately responsible for the protection and use of a specific subset of information. The
data owner decides upon the classification of the data that he is responsible for and alters
that classification if the business needs arise. This person is also responsible for ensuring
that the necessary security controls are in place, ensuring that proper access rights are
being used, defining security requirements per classification and backup requirements,
approving any disclosure activities, and defining user access criteria. The data owner
approves access requests or may choose to delegate this function to business unit
managers. And it is the data owner who will deal with security violations pertaining to the
data he is responsible for protecting. The data owner, who obviously has enough on his
plate, delegates responsibility of the day-to-day maintenance of the data protection
mechanisms to the data custodian.
