CISA Exam Dumps - Certified Information Systems Auditor

Before sending backup drives to an offsite storage facility, the most important thing to do is to encrypt the drive with strong protection standards. This is because encryption ensures effective security where information cannot be intercepted and used to harm the organization or its customers. Encryption also protects the data from unauthorized access, modification, or deletion in case the drive is lost, stolen, or damaged during transit or storage. Encryption of backup drives is especially important for public safety organizations that handle sensitive or personally identifiable information, such as medical records, criminal records, or emergency communications12.

A CO2 system could be a concern for an IS auditor when used to protect an asset storage closet. While CO2 systems are effective at suppressing fires, they can pose a significant safety risk to personnel. In the event of a fire,the CO2 system would fill the room with carbon dioxide, displacing the oxygen. This could be hazardous to anyone who might be in the room at the time12.

 Input validation is the best control to address SQL injection vulnerabilities, because it can prevent malicious users from entering SQL commands or statements into input fields that are intended for data entry, such as usernames or passwords. SQL injection is a technique that exploits a security vulnerability in an application’s software by inserting SQL code into a query string that can execute commands on a database server. Unicode translation, SSL encryption, and digital signatures are not effectivecontrols against SQL injection, because they do not prevent or detect SQL code injection into input fields. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2

A top-down approach in the development of IT policies means that the policies are derived from the strategic objectives and goals of the organization, and are aligned with the business needs and expectations. This should result in greater consistency across the organization, as the policies will be coherent, integrated and applicable to all levels and functions of the organization. A bottom-up approach, on the other hand, means that the policies are developed by individual units or departments based on their operational needs and preferences, which may lead to inconsistency, duplication orconflict among different policies. References: ISACA Frameworks: Blueprints for Success, IT Governance and Process Maturity

 Upon completion of audit work, an IS auditor should distribute a summary of general findings to the members of the auditing team. This is to ensure that the audit team members are aware of the audit results, have an opportunity to provide feedback, and can agree on the audit conclusions and recommendations. Providing a report to senior management prior to discussion with the auditee, providing a report to the auditee stating the initial findings, and reviewing the working papers with the auditee are not appropriate actions for an IS auditor to take upon completion of audit work, as they may compromise the audit independence, objectivity, and quality. References: ISACA CISA Review Manual 27th Edition, page 221

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.
