Project Delta should be deferred by management, as it has the lowest return on investment (ROI) among the four competing projects. ROI is a measure of the profitability or efficiency of a project, calculated by dividing the net benefits by the total costs. Project Delta has a net benefit of $100,000 and a total cost of $200,000, resulting in an ROI of 0.5. The other projects have higher ROIs: Project Alpha has an ROI of 1.0, Project Bravo has an ROI of 0.8, and Project Charlie has an ROI of 0.6. Therefore, Project Delta is the least attractive option for reducingoverall IT risk, and management should prioritize the other projects instead. References = How to Manage Project Risk: A 5-Step Guide; Matching the right projects with the right resources; Risk Types in Project Management

The average time to provision user accounts is the most useful indicator to measure the efficiency of an identity and access management (IAM) process, because it reflects how quickly and smoothly the process can grant access to the appropriate users. The average time to provision user accounts can be calculated by dividing the total time spent on provisioning user accounts by the number of user accounts provisioned in a given period. A lower average time indicates a more efficient IAM process, as it means that users can access the resources they need without unnecessary delays or errors. A higher average time may indicate problems or bottlenecks in the IAM process, such as manual steps, complex workflows, lack of automation, or insufficient resources. The average time to provision user accounts can also be compared across different applications, systems, or business units to identify areas for improvement or best practices. The other options are less useful indicators to measure the efficiency of an IAM process. The number of tickets for provisioning new accounts shows the demand for the IAM process, but not how well the process meets the demand. The password reset volume per month shows the frequency of password-related issues, but not how effectively the IAM process handles them. The average account lockout time shows the impact of account lockouts on user productivity, but not howefficiently the IAM process prevents or resolves them. References = Top Identity and Access Management Metrics 

Multi-factor authentication (MFA)significantly reduces the risk of account compromise by requiring multiple forms of verification, such as a password and a one-time code, enhancing security beyond single-factor authentication methods.

The best recommendation for a risk practitioner upon learning that an employee inadvertently disclosed sensitive data to a vendor is to invoke the incident response plan. An incident responseplan is a document that defines the roles, responsibilities, procedures, and resources fordetecting, analyzing, containing, eradicating, recovering, and reporting on security incidents that could affect the organization’s IT systems or data. An incident response plan helps to protect and restore the confidentiality, integrity, and availability of the organization’s information assets, and to comply with the relevant laws, regulations, standards, and contracts. Invoking the incident response plan is the best recommendation, because it helps to respond to and mitigate the security incident, and to minimize the damage and impact of the data disclosure. Invoking the incident response plan also helps to communicate and coordinate the incident response actions and strategies with the internal and external stakeholders, such as the data owners, users, custodians, and regulators, and to report and disclose the incident as required. The other options are not as effective as invoking the incident response plan, although they may be part of or derived from the incident response plan. Enrolling the employee in additional security training, conducting an internal audit, and instructing the vendor to delete the data are all examples of corrective or preventive actions, which may help to prevent or deter the recurrence of the data disclosure, or to verify or validate the data security, but they do not necessarily address or resolve the current security incident. References = Risk and Information Systems Control Study Manual, Chapter 5, Section 5.4.1, page 5-32.
