Data anonymization is the most important control to ensure the privacy of customer information when participating in an industry benchmarking study that involves providing customer transaction records for analysis. Data anonymization is the process of removing or modifying personally identifiable information (PII) from data sets, such as names, addresses, phone numbers, email addresses, etc., so that the data cannot be traced back to specific individuals. Data anonymization protects the confidentiality and privacy of customers, while still allowing for meaningful analysis and comparison of data. Nondisclosure agreements (NDAs), data cleansing, and data encryption are also useful controls, but they do not eliminate the risk of data breaches or unauthorized access to PII. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.3.1, page 3-21.

The most effective way for a large and diversified organization to minimize risk associated with unauthorized software on company devices is to scan end points for applications not included in the asset inventory. An asset inventory is a document that records and tracks all the hardware and software assets that are owned, used, or managed by the organization, such as laptops, tablets, smartphones, servers, applications, etc. An asset inventory helps to identify and classify the assets based on their type, model, location, owner, status, etc. An asset inventory also helps to monitor and control the assets, such as enforcing security policies, applying patches and updates, detecting and resolving issues, etc. Scanning end points for applications not included in the asset inventory helps to minimize the risk of unauthorized software, because it helps to discover and remove any software that is not approved, authorized, or licensed by the organization, and that may pose security, legal, or operational risks, such as malware, spyware, pirated software, etc. The other options are not as effective as scanning end points for applications not included in the asset inventory, although they may provide some protection or compliance for the software assets. Prohibiting the use of cloud-based virtual desktop software, conducting frequent reviews of software licenses, and performing frequent internal audits of enterprise IT infrastructure are all examples of preventive or detective controls, which may help to prevent or deter the installation or use of unauthorized software, or to verify or validate the software assets, but they do not necessarily discover or remove the unauthorized software. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.2.1, page 3-11.

The most helpful input to develop risk scenarios associated with hosting an organization’s key IT applications in a cloud environment is conducting a risk workshop with key stakeholders. A risk workshop is a facilitated session that involves brainstorming, discussing, and analyzing the potential risks and opportunities related to a specific topic or project. A risk workshop helps to identify and prioritize the most relevant and significant risk scenarios, as well as to explore the possible causes, impacts, and responses. A risk workshop also helps to engage and align the key stakeholders, such as the business owners, IT managers, cloud providers, and risk experts, and to leverage their knowledge, experience, and perspectives. The other options are not as helpful as conducting a risk workshop, although they may provide some input or information for the risk scenario development. Reviewing the results of independent audits, performing a site visit to the cloud provider’s data center, and performing a due diligence review are all activities that can help to assess the current state and performance of the cloud environment, but they do not necessarily generate or evaluate the risk scenarios. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.2.1, page 4-13.

 The primary reason to report the information about the new risk scenarios identified after the implementation of Internet of Things (IoT) devices to risk owners is to confirm the impact to the risk profile. The risk profile is a summary of the level and nature of the risks that the organization faces or may face in the future. The risk profile reflects the risk appetite, tolerance, and capacity of the organization, and guides the risk management decisions and actions. The implementation of IoT devices may introduce new risks or increase the likelihood or impact of existing risks, such as data privacy, security, or interoperability issues. Therefore, the information about the new risk scenarios should be reported to the risk owners, who have the authority and responsibility for managing the risks and their responses, to confirm the impact to the risk profile and to determine the appropriate risk treatment plans. The other options are not as primary as confirming the impact to the risk profile, as they are related to the reevaluation, mitigation, or recommendation of the IoT devices, not the confirmation or assessment of the risk profile. References = Risk and Information Systems Control Study Manual, Chapter 1: IT Risk Identification, Section 1.2: IT Risk Register, page 19.
