CISA Exam Dumps - Certified Information Systems Auditor

 The best detective control for a job scheduling process involving data transmission is job failure alerts that are automatically generated and routed to support personnel. Job failure alerts are notifications that indicate when a scheduled job or task fails to execute or complete successfully, such as due to errors, interruptions, or delays. Job failure alerts can help detect and correct any issues or anomalies in the job scheduling process involving data transmission by informing and alerting the support personnel who can investigate and resolve the problem. The other options are not as effective as job failure alerts in detecting issues or anomalies in the job scheduling process involving data transmission, as they do not provide timely or specific information or feedback. Metrics denoting the volume of monthly job failures are reported and reviewed by senior management is a reporting technique that can help measure and improve the performance and reliability of the job scheduling process, but it does not provide immediate or detailed information on individual job failures. Jobs are scheduled to be completed daily and data is transmitted using a Secure File Transfer Protocol (SFTP) is a preventive control that can help ensure the timeliness and security of the job scheduling process involving data transmission, but it does not detect any issues or anomalies that may occur during the process. Jobs are scheduled and a log of this activity is retained for subsequent review is a logging technique that can help record and track the status and results of the job scheduling process involving data transmission, but it does not provide real-time or proactive information on job failures. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

Aligning IT with business strategy ensures that IT investments provide value and support business objectives.

Option A (Incorrect):While senior management involvement is essential, it is abyproductof alignment rather than the primary goal.

Option B (Correct):Themain purposeof alignment is tooptimize IT investmentsby ensuring that IT initiatives directly support business needs, reducing waste and improving ROI.

Option C (Incorrect):Risk awareness is important but is not theprimaryreason for IT-business alignment.

Option D (Incorrect):Monitoring IT effectiveness is part of governance but not the main objective of IT-business alignment.

A lack ofMobile Device Management (MDM) enrollmentis the biggest concern, asunmanaged devicespose a serious security risk.

Not All Devices Enrolled in MDM (Correct Answer – C)

Unenrolled devices can bypass security policies.

Example:A stolen, unenrolled device may lack encryption, exposing corporate data.

Biometric Authentication Required (Incorrect – A)

Biometrics are anenhanced security measure, not a concern.

VPN Not Required for Internal Network (Incorrect – B)

VPNs are typically used for external access, not always needed internally.

Remote Wipe Requires Internet (Incorrect – D)

A limitation but stillless riskythan allowing unsecured devices.

The most important factor when defining the IS audit scope is to understand the relationship between IT and business risks, as this helps to identify the areas that have the most potential impact on the organization’s objectives, performance, and value. By understanding the IT and business risks, the IS auditor can focus the audit scope on the key processes, systems, controls, and issues that need to be assessed and addressed.

Job scheduling ensures that system resources are allocated efficiently by prioritizing high-priority tasks during peak periods. It prevents resource contention by scheduling less critical jobs at off-peak times or when resources are underutilized. This method is the most direct and effective way to ensure adequate resources for essential activities.

System Virtualization (Option A):While useful for optimizing resource utilization, it does not prioritize activities dynamically.

Zero Trust (Option C):This is a security framework and does not address resource allocation.

Code Optimization (Option D):This improves performance but is not directly related to resource scheduling.

 Including the data warehouse in the impact analysis for any changes in the source system is the best way to prevent data quality issues caused by changes from a source system. A data warehouse is a centralized repository of integrated data from one or more source systems. An impact analysis is a technique of assessing the potential effects and consequences of a change on the existing system or environment. Including the data warehouse in the impact analysis can help to identify and mitigate any data quality issues that may arise from changes in the source system, such as data inconsistency, incompleteness, or inaccuracy. The other options are less effective ways to prevent data quality issues, as they may involve data quality alerts, approval for changes, or access restrictions. References:

 A heuristic intrusion detection system (IDS) provides the most protection against emerging threats, as it uses behavioral analysis and anomaly detection to identify unknown or zero-day attacks. A heuristic IDS can adapt to changing patterns and learn from previous incidents, making it more effective than a signature-based IDS, which relies on predefined rules and signatures to detect known attacks. A demilitarized zone (DMZ) is a network segment that separates the internal network from the external network, and it can provide some protection against external threats, but not against internal or emerging threats. Real-time updating of antivirus software is important to protect against malware, but it may not be sufficient to prevent new or sophisticated attacks that exploit unknown vulnerabilities. References: CISA Review Manual (Digital Version) 1, page 452-453.
