Question No : 3
Which of the following statements best describes the difference between the role of a data owner and the role of a data custodian?
正解:
Explanation:
The data owner is responsible for ensuring that the appropriate security controls are in place, for assigning the initial classification to the data to be protected, for approving access requests from other
parts of the organization, and for periodically reviewing the data classifications and access rights. Data owners are primarily responsible for determining the data's sensitivity or classification levels, whereas the data custodian has the responsibility for backup, retention, and recovery of data. The data owner delegates these responsibilities to the custodian.
ANS: B, A, and C are incorrect. These are not the valid answers.
Question No : 4
Which of the following testing methods verifies the interfaces between components against a software design?
正解:
Explanation:
Integration testing is a software testing that seeks to verify the interfaces between components against a software design. Software components may be integrated in an iterative way or all together ("big bang"). Normally the former is considered a better practice since it allows interface issues to be localized more quickly and fixed. Integration testing works to expose defects in the interfaces and interaction between the integrated components (modules). Progressively larger groups of tested software components corresponding to elements of the architectural design are integrated and tested until the software works as a system.
ANS: A is incorrect. Regression testing focuses on finding defects after a major code change has occurred. Specifically, it seeks to uncover software regressions, or old bugs that have come back. Such regressions occur whenever software functionality that was previously working correctly stops working as intended. Typically, regressions occur as an unintended consequence of program changes, when the newly developed part of the software collides with the previously existing code.
ANS: D is incorrect. Unit testing refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors. These types of tests are usually written by developers as they work on code (white-box style), to ensure that the specific function is working as expected. One function might have multiple tests, to catch corner cases or other branches in the code. Unit testing alone cannot verify the functionality of a piece of software, but rather is used to assure that the building blocks the software uses work independently of each other.
ANS: C is incorrect. The black-box testing uses external descriptions of the software, including specifications, requirements, and design to derive test cases. These tests can be functional or non-functional, though usually functional. The test designer selects valid and invalid inputs and determines the correct output. There is no knowledge of the test object's internal structure. This method of test design is applicable to all levels of software testing: unit, integration, functional testing, system and acceptance. The higher the level, and hence the bigger and more complex the box, the more one is forced to use black box testing to simplify. While this method can uncover unimplemented parts of the specification, one cannot be sure that all existent paths are tested.
Question No : 5
Which of the following access control models are used in the commercial sector? Each correct answer represents a complete solution. Choose two.
正解:
Explanation:
The Biba and Clark-Wilson access control models are used in the commercial sector. The Biba model is a formal state transition system of computer security policy that describes a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity. The model is designed so that subjects may not corrupt data in a level ranked higher than the subject, or be corrupted by data from a lower level than the subject. The Clark-Wilson security model provides a foundation for specifying and analyzing an integrity policy for a computing system.
ANS: D is incorrect. The Bell-LaPadula access control model is mainly used in military systems.
ANS: B is incorrect. There is no such access control model as Clark-Biba.
Question No : 6

The service-oriented modeling framework (SOMF) does not concentrate on it.
Question No : 8
Which of the following is an example of over-the-air (OTA) provisioning in digital rights management?
正解:
Explanation:
Over- the- air provisioning is a mechanism to deploy MIDlet suites over a network. It is a method of distributing MIDlet suites. MIDlet suite providers install their MIDlet suites on Web servers and provide a hypertext link for downloading. A user can use this link to download the MIDlet suite either through the Internet microbrowser or through WAP on his device. Over-the-air provisioning is required for end-to-end encryption or other security purposes in order to deliver copyrighted software to a mobile device. For example, use of shared secrets to initiate or rebuild trust.
ANS: D and C are incorrect. The use of device properties for unique identification and the use of concealment to avoid tampering attacks are the security challenges in digital rights management (DRM).
ANS: B is incorrect. The use of software and hardware to meet the deployment goals is a distracter.

Which of the following statements about the availability concept of Information security management is true?
正解:
Explanation:
The concept of availability ensures reliable and timely access to data or resources. In other words, availability ensures that the systems are up and running when needed. The availability concept also ensures that the security services are in working order.
ANS: A and D are incorrect. The concept of integrity ensures that modifications are not made to data by unauthorized personnel or processes. It also ensures that unauthorized modifications are not made to data by authorized personnel or processes.
ANS: 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 No : 13
Which of the following is a signature-based intrusion detection system (IDS) ?
正解:
Explanation:
Snort is a signature-based intrusion detection system. Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures. Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP). The three main modes in which Snort can be configured are as follows: Sniffer mode: It reads the packets of the network and displays them in a continuous stream on the console. Packet logger mode: It logs the packets to the disk. Network intrusion detection mode: It is the most complex and configurable configuration, allowing Snort to analyze network traffic for matches against a user-defined rule set.
ANS: B is incorrect. StealthWatch is a behavior-based intrusion detection system.
ANS: A is incorrect. RealSecure is a network-based IDS that monitors TCP, UDP and ICMP traffic and is configured to look for attack patterns.

Question No : 15
You work as a project manager for a company. The company has started a new security software project. The software configuration management will be used throughout the lifecycle of the project. You are tasked to modify the functional features and the basic logic of the software and then make them compatible to the initial design of the project.
Which of the following procedures of the configuration management will you follow to accomplish the task?
正解:
Explanation:
Configuration control is a procedure of the Configuration management. Configuration control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. It supports the change of the functional and physical attributes of software at various points in time, and performs systematic control of changes to the identified attributes.
ANS: C is incorrect. Configuration audits confirm that the configuration identification for a configured item is accurate, complete, and will meet specified program needs. Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A
functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation.
ANS: D is incorrect. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. Baselining an attribute forces formal configuration change control processes to be effected in the event that these attributes are changed.
ANS: A is incorrect. The configuration status accounting procedure is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time. It supports the functional and physical attributes of software at various points in time, and performs systematic control of accounting to the identified attributes for the purpose of maintaining software integrity and traceability throughout the software development life cycle.
