質問 # 1392
Which of the following implementation modes would provide the GREATEST amount of security for outbound data connecting to the internet?
正解：A
解説：
Tunnel mode provides protection to the entire IP package. To accomplish this, AH and ESP services can be nested. The transport mode provides primary protection for the higher layers of the protocols by extending protection to the data fields (payload) of an IP package. The SSL mode provides security to the higher communication layers (transport layer). The triple-DES encryption mode is an algorithm that provides confidentiality
質問 # 1393
Which of the following is a distinctive feature of the Secure Electronic Transactions (SET) protocol when used for electronic credit card payments?
正解：D
解説：
Explanation/Reference:
Explanation:
The usual agreement between the credit card issuer and the cardholder stipulates that the cardholder assumes responsibility for any use of their personal SET certificates for e-commerce transactions.
Depending upon the agreement between the merchant and the buyer's credit card issuer, the merchant will have access to the credit card number and expiration date. Secure data storage in the buyer's computer (local computer security) is not part of the SET standard. Although the buyer is not required to enter their credit card data, they will have to handle the wallet software.
質問 # 1394
Which of the following layer from an enterprise data flow architecture captures all data of interest to an
organization and organize it to assist in reporting and analysis?
正解：A
解説：
Section: Information System Acquisition, Development and Implementation
Explanation/Reference:
Core data warehouse -This is where all the data of interest to an organization is captured and organized to
assist reporting and analysis. DWs are normally instituted as large relational databases. A property
constituted DW should support three basic form of an inquiry.
For CISA exam you should know below information about business intelligence:
Business intelligence(BI) is a broad field of IT encompasses the collection and analysis of information to
assist decision making and assess organizational performance.
To deliver effective BI, organizations need to design and implement a data architecture. The complete data
architecture consists of two components
The enterprise data flow architecture (EDFA)
A logical data architecture
Various layers/components of this data flow architecture are as follows:
Presentation/desktop access layer - This is where end users directly deal with information. This layer
includes familiar desktop tools such as spreadsheets, direct querying tools, reporting and analysis suits
offered by vendors such as Congas and business objects, and purpose built application such as balanced
source cards and digital dashboards.
Data Source Layer - Enterprise information derives from number of sources:
Operational data - Data captured and maintained by an organization's existing systems, and usually held in
system-specific database or flat files.
External Data - Data provided to an organization by external sources. This could include data such as
customer demographic and market share information.
Nonoperational data - Information needed by end user that is not currently maintained in a computer
accessible format.
Core data warehouse -This is where all the data of interest to an organization is captured and organized to
assist reporting and analysis. DWs are normally instituted as large relational databases. A property
constituted DW should support three basic form of an inquiry.
Drilling up and drilling down - Using dimension of interest to the business, it should be possible to
aggregate data as well as drill down. Attributes available at the more granular levels of the warehouse can
also be used to refine the analysis.
Drill across - Use common attributes to access a cross section of information in the warehouse such as
sum sales across all product lines by customer and group of customers according to length of association
with the company.
Historical Analysis - The warehouse should support this by holding historical, time variant data. An
example of historical analysis would be to report monthly store sales and then repeat the analysis using
only customer who were preexisting at the start of the year in order to separate the effective new customer
from the ability to generate repeat business with existing customers.
Data Mart Layer- Data mart represents subset of information from the core DW selected and organized to
meet the needs of a particular business unit or business line. Data mart can be relational databases or
some form on-line analytical processing (OLAP) data structure.
Data Staging and quality layer -This layer is responsible for data copying, transformation into DW format
and quality control. It is particularly important that only reliable data into core DW. This layer needs to be
able to deal with problems periodically thrown by operational systems such as change to account number
format and reuse of old accounts and customer numbers.
Data Access Layer -This layer operates to connect the data storage and quality layer with data stores in the
data source layer and, in the process, avoiding the need to know to know exactly how these data stores are
organized. Technology now permits SQL access to data even if it is not stored in a relational database.
Data Preparation layer -This layer is concerned with the assembly and preparation of data for loading into
data marts. The usual practice is to per-calculate the values that are loaded into OLAP data repositories to
increase access speed. Data mining is concern with exploring large volume of data to determine patterns
and trends of information. Data mining often identifies patterns that are counterintuitive due to number and
complexity of data relationships. Data quality needs to be very high to not corrupt the result.
Metadata repository layer - Metadata are data about data. The information held in metadata layer needs to
extend beyond data structure names and formats to provide detail on business purpose and context. The
metadata layer should be comprehensive in scope, covering data as they flow between the various layers,
including documenting transformation and validation rules.
Warehouse Management Layer -The function of this layer is the scheduling of the tasks necessary to build
and maintain the DW and populate data marts. This layer is also involved in administration of security.
Application messaging layer -This layer is concerned with transporting information between the various
layers. In addition to business data, this layer encompasses generation, storage and targeted
communication of control messages.
Internet/Intranet layer - This layer is concerned with basic data communication. Included here are browser
based user interface and TCP/IP networking.
Various analysis models used by data architects/ analysis follows:
Activity or swim-lane diagram - De-construct business processes.
Entity relationship diagram -Depict data entities and how they relate. These data analysis methods
obviously play an important part in developing an enterprise data model. However, it is also crucial that
knowledgeable business operative is involved in the process. This way proper understanding can be
obtained of the business purpose and context of the data. This also mitigates the risk of replication of
suboptimal data configuration from existing systems and database into DW.
The following were incorrect answers:
Desktop access layer or presentation layer is where end users directly deal with information. This layer
includes familiar desktop tools such as spreadsheets, direct querying tools, reporting and analysis suits
offered by vendors such as Congas and business objects, and purpose built application such as balanced
source cards and digital dashboards.
Data access layer - his layer operates to connect the data storage and quality layer with data stores in the
data source layer and, in the process, avoiding the need to know to know exactly how these data stores are
organized. Technology now permits SQL access to data even if it is not stored in a relational database.
Data preparation layer -This layer is concerned with the assembly and preparation of data for loading into
data marts. The usual practice is to per-calculate the values that are loaded into OLAP data repositories to
increase access speed.

Which of the following best characterizes "worms"?
正解：D
解説：
Section: Protection of Information Assets
Explanation
Explanation:
Worms are malicious programs that can run independently and can propagate without the aid of a carrier program such as email.
