CISA Exam Dumps - Certified Information Systems Auditor

A business impact analysis (BIA) is a process that identifies and evaluates the potential effects of disruptions to critical business operations as a result of a disaster, accident or emergency. A BIA should include an inventory of relevant business processes that support the organization’s strategic objectives and are essential for its continuity. The inventory should also identify the dependencies, interdependencies, recovery priorities and time frames for each business process. Policies for business procurement, documentation of application configurations and results of business resumption planning efforts are not as useful as an inventory of relevant business processes for performing a BIA. References:

 Information security policies and procedures are the foundation of an organization’s information security program. They define the roles, responsibilities, rules, and standards for protecting information assets from unauthorized access, use, disclosure, modification, or destruction. The most important factor when developing information security policies and procedures is to align them with an information security framework that provides a comprehensive and consistent approach to managing information security risks. An information security framework can also help ensure compliance with relevant regulations, inclusion of mission and objectives, and consultation with security staff. However, these factors are secondary to alignment with an information security framework. References: CISA Certification | Certified Information Systems Auditor | ISACA, CISA Review Manual (Digital Version)

 The best performance indicator for the effectiveness of an incident management program is the incident resolution meantime. This is the average time it takes to resolve an incident from the moment it is reported to the moment it is closed. The incident resolution meantime reflects how quickly and efficiently the incident management team can restore normal service and minimize the impact of incidents on the business operations and customer satisfaction.

The average time between incidents (option A) is not a good performance indicator for the effectiveness of an incident management program, as it does not measure how well the incidents are handled or resolved. It only shows how frequently the incidents occur, which may depend on various factors beyond the control of the incident management team, such as the complexity and reliability of the systems, the security threats and vulnerabilities, and the user behavior and expectations.

The incident alert meantime (option B) is the average time it takes to detect and report an incident. While this is an important metric for measuring the responsiveness and awareness of the incident management team, it does not indicate how effective the incident management program is in resolving the incidents and restoring normal service.

The number of incidents reported (option C) is also not a good performance indicator for the effectiveness of an incident management program, as it does not reflect how well the incidents are handled or resolved. It only shows how many incidents are identified and recorded, which may vary depending on the reporting channels, tools, and procedures used by the incident management team and the users.

Therefore, option D is the correct answer.

 A stateful firewall provides the greatest assurance that outgoing Internet traffic is controlled, as it monitors and filters packets based on their source, destination and connection state. A stateful firewall can prevent unauthorized or malicious traffic from leaving the network, as well as block incoming traffic that does not match an established connection. An intrusion detection system (IDS) can detect and alert on suspicious or anomalous traffic, but it does not block or control it. A security information and event management (SIEM) system can collect and analyze logs and events from various sources, but it does not directly control traffic. A load balancer can distribute traffic among multiple servers, but it does not filter or monitor it. References: CISA Review Manual (Digital Version), Chapter 6, Section 6.2

 Implementing an email containerization solution on personal devices is the best recommendation for an IS auditor, because it allows the organization to separate and secure the email data from the rest of the device data. Email containerization creates a virtual environment that encrypts and isolates the email data, preventing unauthorized access, leakage, or loss of sensitive information12. Requiring passwords or antivirus protection on personal devices may not be sufficient or enforceable, while prohibiting employees from storing company email on personal devices may not be feasible or practical. References: 1: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.3 2: CISA Online Review Course, Module 5, Lesson 4

The greatest advantage of vulnerability scanning over penetration testing is that the testing process can be automated to cover large groups of assets. Vulnerability scanning is an automated, high-level security test that reports its findings of known vulnerabilities in systems, networks, applications, and devices. Vulnerability scanning can be performed frequently, quickly, and efficiently to scan a large number of assets and identify potential weaknesses that need to be addressed. Vulnerability scanning can also help organizations comply with security standards and regulations, such as PCI DSS1.

The other options are not as advantageous as option D, as they may not reflect the true benefits or limitations of vulnerability scanning compared to penetration testing. The testing produces a lower number of false positive results, but this is not necessarily true, as vulnerability scanning may report vulnerabilities that are not exploitable or relevant in the context of the organization. Network bandwidth is utilized more efficiently, but this may not be a significant advantage, as vulnerability scanning may still consume considerable network resources depending on the scope and frequency of the scans. Custom-developed applications can be tested more accurately, but this is also not true, as vulnerability scanning may not be able to detect complex or unknown vulnerabilities that require manual analysis or exploitation.
