CISA Exam Dumps - Certified Information Systems Auditor

The correct answer is B. Discuss the concern with audit management.

When an employee reports a critical security concern to an IS auditor, the auditor should first discuss the matter with audit management. This ensures the concern is handled through the proper audit reporting and escalation process. Audit management can help determine whether the issue is within audit scope, whether immediate escalation is needed, whether a special review should be authorized, and whether legal, compliance, security, or executive management should be involved.

Option A is not correct because recommending a rollback is a management decision. The auditor should not directly decide or recommend operational action without proper evaluation and authorization. Option C may become appropriate later, but the auditor should not independently begin an application review without audit management’s awareness and approval. Option D may be required if legal implications exist, but the auditor should not go directly to legal counsel before following the audit escalation process unless required by policy or law.

This question maps to Information Systems Auditing Process because it concerns audit communication, escalation, auditor responsibility, and handling audit-relevant information. ISACA’s CISA Exam Content Outline includes IS audit standards, audit planning, audit evidence, audit reporting, and communication of audit results under Domain 1.

The performance and reliability of a job scheduling tool can be significantly affected if maintenance patches and the latest enhancement upgrades are missing1. These patches and upgrades often contain fixes for known issues and improvements to the tool’s functionality. If they are not applied, the tool may continue to exhibit known problems or fail to benefit from enhancements that could improve its performance and reliability1. While factors like administrator password requirements23, number of support staff45, and tool classification64 can impact various aspects of a tool’s operation, they are less likely to be the direct cause of performance and reliability problems.

 The auditor should be most concerned about the security policy documents being available on a public domain website. This is because this exposes the organization’s security posture and strategy to potential attackers, who can exploit the information to launch targeted attacks or bypass the security controls. The security policy documents should be classified as confidential and protected from unauthorized access or disclosure. The other options are less severe than exposing the security policy documents to the public, although they may also indicate some gaps or weaknesses in the security policy development, implementation, or maintenance process. References:

The most important factor when planning a network audit is to identify the existing nodes on the network. Nodes are devices or systems that are connected to the network and can communicate with each other. Nodes can include servers, workstations, routers, switches, firewalls, printers, scanners, cameras, etc. Identifying the existing nodes on the network will help the auditor to determine the scope, objectives, and methodology of the audit. It will also help the auditor to assess the network topology, architecture, performance, security, and compliance. References:

CISA Questions, Answers and Explanations Database

The most effective way to identify exfiltration of sensitive data by a malicious insider is to establish behavioral analytics monitoring. Behavioral analytics is the process of analyzing the patterns and anomalies in user behavior to detect and prevent insider threats. Behavioral analytics can help identify unusual or suspicious activities, such as accessing sensitive data at odd hours, transferring large amounts of data to external devices or locations, or using unauthorized applications or protocols. Behavioral analytics can also help correlate data from multiple sources, such as network logs, user profiles, and access rights, to provide a holistic view of user activity and risk.

Data loss prevention (DLP) software is a tool that can help prevent exfiltration of sensitive data by a malicious insider, but it is not the most effective way to identify it. DLP software can block or alert on unauthorized data transfers based on predefined rules and policies, but it may not be able to detect sophisticated or stealthy exfiltration techniques, such as encryption, steganography, or data obfuscation.

Reviewing perimeter firewall logs is a way to identify exfiltration of sensitive data by a malicious insider, but it is not the most effective way. Perimeter firewall logs can show the traffic volume and destination of data transfers, but they may not be able to show the content or context of the data. Perimeter firewall logs may also be overwhelmed by the amount of normal traffic and miss the signals of malicious exfiltration.

Providing ongoing information security awareness training is a way to reduce the risk of exfiltration of sensitive data by a malicious insider, but it is not a way to identify it. Information security awareness training can help educate users on the importance of protecting sensitive data and the consequences of violating policies and regulations, but it may not deter or detect those who are intentionally or maliciously exfiltrating data.

Consolidating mission-critical applications onto a single large server introduces a single point of failure. If the server experiences an outage, all hosted applications could be impacted simultaneously, leading to significant operational disruptions. While continuous monitoring costs, potential network bandwidth issues, and challenges in capacity forecasting are valid concerns, the risk of a single outage affecting multiple critical applications presents the most substantial threat to business continuity.

The correct answer is A. Differences in infrastructure capabilities.

A reciprocal arrangement is a recovery strategy in which another organization agrees to provide facilities or processing capability during a disruption. The most important consideration is whether the other party’s infrastructure can actually support the recovering organization’s critical systems, workloads, data, applications, network connectivity, capacity, and recovery time requirements.

If infrastructure capabilities are incompatible or insufficient, the reciprocal arrangement will fail regardless of whether security policies, service expectations, or staff skills are acceptable. For example, if the recovery partner lacks compatible hardware, sufficient processing capacity, adequate storage, required network connectivity, or application platform compatibility, the organization may not be able to recover critical services.

ISACA defines a recovery strategy as an approach that ensures recovery and continuity in the face of a disaster or major outage, and it lists a consortium or reciprocal agreement as one possible recovery methodology. ISACA also describes recovery solutions in terms of the technical, physical, procedural, and human resources needed to recover within defined time and cost limits.

Option B is important because security requirements must still be maintained during recovery, but security-policy differences are secondary if the environment cannot technically support recovery.

Option C is important because service levels should be aligned, but service expectations cannot be achieved without adequate infrastructure capability.

Option D is important because staff competence affects recovery execution, but the first practical question is whether the reciprocal site can support the required systems and processing.

 Changes to the job scheduler application’s parameters are not approved and reviewed by an operations supervisor. This is a serious control weakness that could compromise the integrity, availability, and security of the IT operations. An IS auditor should be concerned about the lack of oversight and accountability for such changes, which could result in unauthorized, erroneous, or malicious modifications that affect the processing environment. The other options are less critical issues that may not have a significant impact on the IT operations. References:
