ISACA Certified Information Systems Auditor (CISA) Exam

D. Employees may inadvertently expose sensitive information due to a lack of clear guidance.

An effective information security policy must be clear, specific, and actionable. Vague wording that fails to define key terms or specify expected behaviors and consequences makes it impossible for employees to understand or comply with their obligations, leading to inconsistent application and potential security breaches.

B. Higher likelihood of non-compliance with software vendor licensing agreements.

Without ongoing monitoring of software installations and usage, an organization runs a significant risk of being over-licensed (wasting money) or, more critically, under-licensed, leading to non-compliance with software vendor agreements. This can result in hefty fines, legal action, and reputational damage.

B. Lack of continuous requirements validation.

The scenario indicates that while the project is technically on track (on schedule, within budget), the delivered solution might not meet 'evolving business intelligence needs.' This points to a failure in continuously validating that the system being built still aligns with current and future business requirements, especially in dynamic environments like data analytics.

B. Misalignment of IT investments with business strategy.

If IT implements new technologies without formal cross-functional approval, it indicates a lack of effective governance oversight. This bypasses the mechanism designed to ensure IT projects align with overall business objectives, leading to potential investments in technologies that do not support strategic goals or create unintended business risks.

A. Resistance from management and employees to adapt to new processes and responsibilities.

Significant cultural changes and new reporting structures directly challenge established norms and power dynamics within an organization. Resistance from management and employees to adapt to these fundamental shifts is a common and often the most difficult barrier to successful implementation of new governance frameworks or any organizational change.

A. Elevated risk of unauthorized access and data breaches.

Granting broad access immediately and conducting infrequent reviews creates a significant window of opportunity for unauthorized actions, whether accidental or malicious. This practice directly increases the risk of data breaches and compromises system integrity, as access is not aligned with the principle of least privilege or need-to-know.

B. Segregation of duties between development, testing, and production environments.

Segregation of duties (SoD) between development, testing, and production environments is a fundamental control that prevents unauthorized or untested code from being promoted to production. It ensures that no single individual or team has control over all stages of the software development lifecycle, thereby reducing the risk of fraud or errors.

B. Erosion of the organization's security posture over time.

Security awareness is not a one-time event; threats evolve, and human memory fades. Without regular, ongoing training, employees' understanding of security policies and best practices will diminish, leading to a weakened human firewall and an increased susceptibility to social engineering attacks, phishing, and other security incidents, thereby eroding the overall security posture.

A. Inability to recover the system in the event of a major disruption after go-live.

For a critical online banking system, the inability to recover from a major disruption (due to an untested DRP for the new system) poses the most significant and immediate threat to business continuity, customer trust, and regulatory obligations post-go-live.

C. Extended downtime for critical applications due to inefficient data recovery.

Without detailed data backup and restoration procedures, especially for complex systems, the actual recovery process will be inefficient, error-prone, and significantly prolonged. This directly translates to exceeding established RTOs and extended downtime for critical business applications.

C. The organization's policy statement is effectively unenforceable and non-compliant.

Without regular security audits or reviews of the cloud provider, the organization has no way to verify if its policy requirement ('same security standards as on-premise data') is actually being met. This renders the policy unenforceable in practice and exposes the organization to unknown security risks, making it non-compliant with its own stated policy.

A. High probability of recovery failures due to lack of specialized knowledge.

Given the application's age, customization, lack of original developers, and sparse documentation, the most significant challenge is the high likelihood that recovery efforts will fail due to the absence of the specific, specialized knowledge required to effectively restore and configure such a unique and complex legacy system. Generic steps are insufficient.

A. Lack of alignment between IT initiatives and business objectives.

When IT projects are initiated without formal business unit approval, it indicates a fundamental breakdown in the alignment between IT and the business. This directly leads to projects that may not support strategic organizational goals, making lack of alignment the most significant implication.

C. They make it difficult to enforce compliance and measure effectiveness.

Descriptive policies that lack specific instructions and measurable outcomes severely hinder the organization's ability to enforce compliance and objectively assess whether the policies are achieving their intended security goals. Without clear metrics and actionable directives, it is challenging to hold individuals accountable or to demonstrate policy effectiveness.

C. The system may not effectively support critical business processes.

Effective IT governance requires strong alignment between IT projects and business needs. Minimal involvement of business representatives in requirements and testing significantly increases the risk that the new ERP system will not meet actual business process needs, leading to low user adoption and failure to achieve strategic objectives.

C. Insufficient oversight to ensure vendor performance meets contractual obligations.

While all options represent weaknesses, the most critical is the lack of a mechanism to monitor SLA adherence. Without this, the organization cannot verify if the service provider is meeting its contractual obligations, effectively nullifying the purpose of having SLAs and exposing the organization to operational and financial risks without recourse.

C. The vendor's ability to meet critical business requirements.

For a complex system like ERP, the vendor's ability to meet critical business requirements is paramount. Without this, even a low-cost, reputable vendor with a fast timeline will deliver a system that fails to support core business operations, leading to significant financial and operational losses.

C. Potential for unauthorized access to sensitive systems and data.

Failure to promptly revoke access rights for terminated employees creates a critical window of opportunity for unauthorized access, potentially leading to data breaches, system compromise, or malicious activity, which is a severe security risk.

C. It is not sufficiently actionable or enforceable due to lack of specificity.

From an audit perspective, a policy statement must be clear, measurable, and enforceable. Without specifying 'how' encryption should be achieved (algorithms, key lengths, protocols), the policy becomes difficult to implement consistently and impossible to audit for compliance effectively, making it not actionable or enforceable.

D. Reduced system availability due to new defects introduced.

Implementing changes directly into production without testing in a separate environment significantly increases the risk of introducing new defects, regressions, or incompatibilities. These untested changes can lead to system crashes, data corruption, or unexpected behavior, directly resulting in reduced system availability and service disruptions.

A. Security priorities may be deprioritized in favor of IT operational efficiency.

When the CISO reports to the CIO, there's an inherent conflict of interest. The CIO's primary focus is often on IT service delivery, operational efficiency, and project completion, while the CISO's role is to ensure security, which can sometimes impose constraints on operations. This structure can lead to security concerns being overlooked or deprioritized to meet operational goals.

D. Integrating security activities, such as threat modeling and secure code reviews, into each sprint.

Integrating security activities into each sprint (often called 'shifting left') ensures that security is built into the application incrementally, addressing vulnerabilities early and reducing remediation costs.

D. 0.938

The Cost Performance Index (CPI) measures the cost efficiency of a project. It is calculated as BCWP / ACWP. In this case, $750,000 / $800,000 = 0.9375, which rounds to 0.938.

A. Opportunities for fraud, errors, or unauthorized changes are significantly increased.

This scenario describes a severe lack of segregation of duties (SoD). Allowing one person to control development, testing, deployment, and production database management creates an environment where malicious acts, errors, or unauthorized changes could occur undetected and unprevented, leading to significant integrity and security risks.

D. Adequate testing of changes before deployment.

Significant performance degradation after production updates strongly suggests that the changes were not adequately tested for their impact on system performance, stability, or resource utilization before being deployed to the live environment.
