CISA Exam Dumps - Certified Information Systems Auditor

The most important consideration for an IS auditor when assessing the adequacy of an organization’s information security policy is the business objectives. An information security policy is a document that defines the organization’s approach to protecting its information assets from internal and external threats. It should align with the organization’s mission, vision, values, and goals, and support its business processes and functions1. An informationsecurity policy should also be focused on the business needs and requirements of the organization, rather than on technical details orspecific solutions2.

The other options are not as important as the business objectives, because they do not directly reflect the organization’s purpose and direction. IT steering committee minutes are records of the discussions and decisions made by a group of senior executives who oversee the IT strategy and governance of the organization. They may provide some insights into the information security policy, but they are not sufficientto evaluate its adequacy3. Alignment with the IT tactical plan is a measure of how well the information security policy supports the short-term actions and projects that implement the IT strategy. However, the IT tactical plan itself shouldbe aligned with the business objectives, and not vice versa4. Compliance with industry best practice is a desirable quality of an information security policy, but it is not a guarantee of its effectiveness or suitability for the organization. Industry best practices are general guidelines or recommendations that may not apply to every organization or situation. An information security policy should be customized and tailored to the specific context and needs of the organization. References:

The best way to ensure data integrity across system interfaces is to perform reconciliation. Reconciliation is the process of comparing and verifying the data from different sources or systems to ensure that they are consistent, accurate, and complete. Reconciliation can help to identify and resolve any discrepancies, errors, or anomalies in the data that could affect the quality, reliability, or validity of the information. Reconciliation can also help to detect and prevent any unauthorized or fraudulent data manipulation or modification. References:

The primary objective of an IS auditor when reviewing the installation of a new server is to ensure that security parameters are set in accordance with the organization’s policies. Security parameters are settingsor options that control the security level and behavior of the server, such as authentication methods, encryption algorithms, access rights, audit logs, firewall rules, or password policies7. The organization’s policies are documents that define the security goals, requirements, standards, and guidelines for the organization’s information systems. An IS auditor should verify that security parameters are set in accordance with the organization’s policies to ensure that the new server complies with the organization’s security expectations and regulations. The other options are less important or incorrect because:

A. Security parameters should not be set in accordance with the manufacturer’s standards alone, as they may not reflect the organization’s specific security needs and environment. The manufacturer’s standards are general recommendations or best practices for configuring the server’s security parameters based on common scenarios and threats. An IS auditor should compare the manufacturer’s standards with the organization’s policies and identify any gaps or conflicts that need to be resolved.

B. A detailed business case should have been formally approved prior to the purchase of a new server rather than during its installation. A business case is a document that justifies the need for a new server based on its expected benefits, costs, risks, and alternatives. A business case should be approved by senior management before initiating a project to acquire a new server.

D. The procurement project should have invited tenders from at least three different suppliers before purchasing a new server rather than during its installation. A tender is a formal offer or proposal to provide a product or service at a specified price and quality. Inviting tenders from multiple suppliers helps to ensure a fair and competitive procurement process that can result in the best value for money and quality for the organization. References: Server Security - ISACA, [Information Security Policy - ISACA], [Server Hardening - ISACA], [Business Case - ISACA], [Tender - ISACA], [Procurement Management - ISACA]

A mobile device awareness program would best enable an organization to address the security risks associated with a recently implemented bring your own device (BYOD) strategy. A mobile device awareness program is a set of activities that aim to educate and inform the employees about the benefits, challenges, and best practices of using their personal mobile devices for work purposes. A mobile device awareness program can help the organization to:

Communicate the organization’s policies and expectations regarding BYOD, such as which devices are allowed, what data can be accessed or stored, and what security measures are required.

Raise the employees’ awareness of the potential threats and vulnerabilities that affect their mobile devices, such as malware, phishing, data leakage, or device loss.

Provide the employees with guidance and tips on how to protect their mobile devices and the organization’s data, such as using strong passwords, encryption, antivirus software, remote wipe, or VPN.

Encourage the employees to report any incidents or issues related to their mobile devices, such as suspicious messages, unauthorized access, or device damage.

A mobile device awareness program can help the organization to reduce the security risks associated with BYOD by enhancing the employees’ knowledge, skills, and behavior in using their mobile devices securely and responsibly. Amobile device awareness program can also help the organization to comply with relevant regulations and standards that governdata privacy and security in the cloud1.

The other options are not as effective as a mobile device awareness program in enabling an organization to address the security risks associated with BYOD. Option A, mobile device tracking program, is a tool that allows the organization to monitor and locate the employees’ mobile devices in case of loss or theft. However, this tool may not prevent or detect other types of security risks, such as malware infection or data breach. Option B, mobile device upgrade program, is a process that ensures that the employees’ mobile devices are running the latest versions of operating systems and applications. However, this process may not address other aspects of security, such as user behavior or data protection. Option C, mobile device testing program, is a method that verifies the functionality and compatibility of the employees’ mobile devices with the organization’s systems and networks. However, this method may not cover all the scenarios or factors that may affect the security of the mobile devices or the organization’s data2.

 The most critical finding for an IS auditor following up on a recent security incident is that the security weakness facilitating the attack was not identified. This finding indicates that the root cause of the incident was not analyzed, and the vulnerability that allowed the attack to succeed was not remediated. This means that the organization is still exposed to the same or similar attacks in the future, and its security posture has not improved. Identifying and addressing the security weakness is a key step in the incident response process, as it helps to prevent recurrence, mitigate impact, and improve resilience.

The other findings are not as critical as the failure to identify the security weakness, but they are still important issues that should be addressed by the organization. The attack was not automatically blocked by the intrusion detection system (IDS) is a finding that suggests that the IDS was not configured properly, or that it did not have the latest signatures or rules to detect and prevent the attack. The attack could not be traced back to the originating person is a finding that implies that the organization did not have sufficient logging, monitoring, or forensic capabilities to identify and attribute the attacker. Appropriate response documentation was not maintained is a finding that indicates that the organization did not follow a consistent and formal incident response procedure, or that it did not document its actions, decisions, and lessons learned from the incident.
