CISA Exam Dumps - Certified Information Systems Auditor

The most important thing to determine during the planning phase of a cloud-based messaging and collaboration platform acquisition is the types of data that can be uploaded to the platform. This is because different types of data may have different security, privacy, and compliance requirements, depending on the nature, sensitivity, and value of the data. For example, personal data, financial data, health data, or intellectual property data may be subject to various laws and regulations thatgovern how they can be collected, stored, processed, and shared in the cloud. Therefore, it is essential to identify and classify the types of data that will be uploadedto the platform, and ensure that the platform meets the organization’s policies and standards for data protection1.

The other options are not as important as the types of data that can be uploaded to the platform during the planning phase of a cloud-based messaging and collaboration platform acquisition. Option A, role-based access control policies, is a mechanism that defines who can access what data and resources on the platform based on their roles and responsibilities. Role-based access control policies are important for ensuring data security and accountability, but they can be designed and implemented after the platform is acquired2. Option C, processes for on-boarding and off-boarding users to the platform, are procedures that enable or disable user accounts and access rights on the platform. Processes for on-boarding and off-boarding users are important for managing user identities and lifecycles, but they can be developed and executed after the platform is acquired3. Option D, processes for reviewing administrator activity, are methods that monitor and audit the actions and events performed by administrators on the platform. Processes for reviewing administrator activity are important for detecting and preventing unauthorized or malicious activities, but they can be established and performed after the platform is acquired4.

Conducting vulnerability assessmentsonly once per year, right before an audit,creates a false sense of securityandleaves systems exposedbetween assessments.

Annual Testing Before Audit (Correct Answer – A)

Risksundetected vulnerabilitiesfor extended periods.

Example:A company only tests security before acompliance audit, allowingzero-day threatsto persist for months.

Internal Team Conducting Assessments (Incorrect – B)

Not ideal, butregular assessmentsare more critical.

Focusing on Critical Systems (Incorrect – C)

Not perfect, butbetter than no testing at all.

Using Open-Source Tools (Incorrect – D)

Open-source toolscan be effective ifproperly configured.

A continuous integration/continuous development (CI/CD) process helps to reduce software failure risk by enabling smaller incremental changes to the software code, rather than large and infrequent updates12. Smaller incremental changes allow developers to detect and fix errors, bugs, or vulnerabilities more quickly and easily, and to ensure that the software is always in a working state34. Smaller incremental changes also reduce the complexity and uncertainty of the software development process, and improve the quality and reliability of the software product5.

Comprehensive and Detailed in-Depth Explanation:

A passive attack involves monitoring or listening without altering data or system operations. Eavesdropping is a classic example, where attackers intercept data without affecting the transmission.

Keystroke logging (Option A) and phishing (Option D) are active attacks. Piggybacking (Option B) involves unauthorized access and is also active.

Risk-based auditing is an audit approach that focuses on the analysis and management of risk within an organization. Risk-based auditing helps identify and prioritize the areas or processes that pose the highest risk to the organization’s objectives and allocate audit resources accordingly. Risk-based auditing also helps provide assurance and advisory services related to the organization’s risk management processes and controls. By using risk-based auditing, internal auditors can optimize the use of their audit resources and add value to the organization.

Agile auditing, continuous auditing, and outsourced auditing are not audit approaches that are most helpful in optimizing the use of IS audit resources. Agile auditing is a flexible and iterative audit methodology that adapts to changing circumstances and stakeholder needs. Continuous auditing is a method of performing audit activities on a real-time or near-real-time basis using automated tools and techniques. Outsourced auditing is a practice of contracting external auditors to perform some or all of the internal audit functions. These audit methods may have some advantages or disadvantages depending on the context and objectives of the audit, but they do not necessarily optimize the use of IS audit resources.

A monitored mantrap at entrance and exit points would be the most effective compensating control in this scenario. A mantrap is a physical security access control system comprising a small space having two sets of interlockingdoors such that the first set of doors must close before the second set opens. By implementing a monitored mantrap, unauthorized access can be prevented and it can ensure that all individuals are logged when they enter and exit the server room12.
