ISACA Certified Information Systems Auditor 認定 CISA 試験問題 (Q454-Q459):

質問 # 454
Which of the following will BEST protect the confidentiality of data stored on the hard drive of a laptop computer?

A. A boot password
B. Physical locks and alarms
C. Biometric access control
D. Encryption of the data

正解：D

質問 # 455
A senior auditor is reviewing work papers prepared by a junior auditor indicating that a finding was removed after the auditee said they corrected the problem. Which of the following is the senior auditor s MOST appropriate course of action?

A. Have the finding reinstated
B. Refer the issue to the audit director
C. Ask the auditee to retest
D. Approve the work papers as written

正解：A

解説：
The senior auditor's most appropriate course of action is to have the finding reinstated, because the auditee's claim of correcting the problem is not sufficient evidence to support the removal of the finding. The auditor should verify that the corrective action has been implemented effectively and that it has resolved the underlying issue or risk. The auditor should also document the evidence and results of the verification in the work papers. The other options are not appropriate, because they either accept the auditee's claim without verification, delegate the responsibility to the auditee or escalate the issue unnecessarily. References:

質問 # 456
To confirm integrity for a hashed message, the receiver should use:

A. a different hashing algorithm from the sender's to create a binary image of the file.
B. the same hashing algorithm as the sender's to create a numerical representation of the file.
C. a different hashing algorithm from the sender's to create a numerical representation of the file.
D. the same hashing algorithm as the sender's to create a binary image of the file.

正解：D

解説：
To confirm integrity for a hashed message, the receiver should use the same hashing algorithm as the sender' s to create a binary image of the file. A hashing algorithm is a mathematical function that transforms an input data into a fixed-length output value, called a hash or a digest. A hashing algorithm has two main properties:
it is one-way, meaning that it is easy to compute the hash from the input, but hard to recover the input from the hash; and it is collision-resistant, meaning that it is very unlikely to find two different inputs that produce the same hash. These properties make hashing algorithms useful for verifying the integrity of data, as any change in the input data will result in a different hash value. Therefore, to confirm integrity for a hashed message, the receiver should use the same hashing algorithm as the sender's to create a binary image of the file, which is a representation of the file in bits (0s and 1s). The receiver should then compare this binary image with the hash value sent by the sender. If they match, then the message has not been altered in transit.
If they do not match, then the message has been corrupted or tampered with.

質問 # 457
Which of the following is a guiding best practice for implementing logical access controls?

A. Implementing the Take-Grant access control model
B. Implementing the Biba Integrity Model
C. Access is granted on a least-privilege basis, per the organization's data owners
D. Classifying data according to the subject's requirements

正解：C

解説：
Section: Protection of Information Assets
Explanation:
Logical access controls should be reviewed to ensure that access is granted on a least-privilege basis, per the organization's data owners.

質問 # 458
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?

A. Data preparation layer
B. Core data warehouse
C. Data access layer
D. Desktop access layer

正解：B

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.
