CISA Exam Dumps - Certified Information Systems Auditor

 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:

 The first thing that should be done when an intrusion into an organization network is detected is to identify nodes that have been compromised. Identifying nodes that have been compromised is a critical step in responding to an intrusion, as it helps determine the scope, impact, and source of the attack, and enables the implementation of appropriate containment and recovery measures. The other options are not the first things that should be done when an intrusion into an organization network is detected, as they may be premature or ineffective without identifying nodes that have been compromised. Blocking all compromised network nodes is a containment measure that can help isolate and prevent the spread of the attack, but it may not be possible or feasible without identifying nodes that have been compromised. Contacting law enforcement is a reporting measure that can help seek external assistance and comply with legal obligations, but it may not be necessary or appropriate without identifying nodes that have been compromised. Notifying senior management is a communication measure that can help inform and escalate the incident, but it may not be urgent or accurate without identifying nodes that have been compromised. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.2

The best recommendation for an IS auditor who finds that one employee has unauthorized access to confidential data is to require the business owner to conduct regular access reviews. Access reviews are periodic assessments of user access rights and permissions to ensure that they are appropriate, necessary, and aligned with the business needs and objectives. Access reviews help to identify and remediate any unauthorized, excessive, or obsolete access that could pose a security risk or violate compliance requirements. The business owner is responsible for defining and approving the access requirements for their data and ensuring that they are enforced and monitored. References:

Comprehensive and Detailed Explanation:

The best approach is to establish a clear AI acceptable use policy that defines how employees may use AI tools while protecting sensitive information and intellectual property. This ensures governance while enabling safe adoption.

Option B: Reactive and punitive, not proactive governance.

Option C: Monitoring helps but is insufficient alone.

Option D: Overly restrictive and may block beneficial AI use.

Option A: Correct — policies provide structured guidance aligned with business objectives and risk management.

 The strategy that would provide the greatest assurance of system quality at implementation is delivering only the core functionality on the initial target date. This strategy can help avoid compromising the quality of the system by focusing on the essential features that meet the user needs and expectations. Delivering only the core functionality can also help reduce the scope creep, complexity, and testing efforts of the system development project.

Implementing overtime pay and bonuses for all development staff, utilizing new system development tools to improve productivity, and recruiting IS staff to expedite system development are not strategies that would provide the greatest assurance of system quality at implementation. These strategies may help speed up the system development process, but they may also introduce new risks or challenges such as burnout, learning curve, integration issues, or communication gaps. These risks or challenges may adversely affect the quality of the system.

The first thing that an IS auditor should recommend when an organization is made aware of a new regulation that is likely to impact IT security requirements is to determine which systems and IT-related processes may be impacted. This is because the impact assessment is a crucial step to understand the scope and magnitude of the changes that the new regulation may entail, as well as the potential risks and gaps that need to be addressed. The impact assessment can help the organization to prioritize and plan the necessary actions and resourcesto comply with the new regulation in a timely and effective manner12.

Updating security policies based on the new regulation is not the first thing to do, because it requires a clear understanding of the impact and implications of the new regulation, which can only be obtained after conducting an impact assessment. Updating security policies without an impact assessment may result in incomplete, inconsistent, or ineffective policies that may not meet the regulatory requirements or the organizational needs12.

Evaluating how security awareness and training content may be impacted is not the first thing to do, because it is a secondary or supporting activity that depends on the results of the impact assessment and the policy updates. Evaluating security awareness and training content without an impact assessment or policy updates may result in inaccurate, outdated, or irrelevant content that may not reflect the regulatory requirements or the organizational expectations34.

Reviewing the design and effectiveness of existing IT controls is not the first thing to do, because it is a monitoring or assurance activity that follows the implementation of the changes based on the impact assessment and the policy updates. Reviewing IT controls without an impact assessment or policy updates may result in misleading, incomplete, or invalidfindings that may not capture the regulatory requirements or the organizational performance

The primary basis on which audit objectives are established is the consideration of risks12. This involves identifying and assessing the risks that could prevent the organization from achieving its objectives12. The audit objectives are then designed to address these risks and provide assurance that the organization’s controls are effective in managing them12. While audit risk, assessment of prior audits, and business strategy are important factors in the audit process, they are secondary to the fundamental requirement of considering risks12.
