A risk and control framework is a set of principles, processes, and tools that guide an organization in identifying, assessing, managing, and monitoring the risks and controls that affect its objectives and performance. A risk and control framework helps an organization to align its risk appetite and tolerance with its strategy, culture, and values, and to ensure that its security controls are appropriate, effective, and efficient1.

Re-evaluating the organization’s risk and control framework is the best recommendation to management because it can help them to:

Review the current risk environment and the sources, causes, and impacts of potential threats and vulnerabilities.

Update the risk assessment and analysis methods and criteria, such as likelihood, impact, severity, and priority.

Reconsider the risk response and treatment options, such as avoidance, reduction, transfer, or acceptance.

Realign the security controls with the risk profile and the business needs and expectations.

Evaluate the performance and effectiveness of the security controls using key indicators and metrics.

Identify the gaps, weaknesses, or inefficiencies in the security controls and implement corrective or improvement actions.

Communicate and report the risk and control status and results to relevant stakeholders.

Re-evaluating the organization’s risk and control framework can help management to determine whether the current security controls are excessive or not, and to make informed and rational decisions on how to adjust them accordingly.

Multi-tenancy within the same database (B) presents the greatest risk of data leakage in the cloud environment, because it means that multiple customers share the same physical database and resources. This can lead to data isolation and security issues, such as unauthorized access, cross-tenant attacks, or data leakage due to misconfiguration or human error. To prevent data leakage in a multi-tenant database, cloud providers need to implement strict access control policies, encryption, isolation mechanisms, and auditing tools.

Lack of data retention policy (A) is not the greatest risk of data leakage in the cloud environment, because it mainly affects the availability and compliance of data, not its confidentiality or integrity. Data retention policy defines how long data should be stored and when it should be deleted or archived. Without a data retention policy, cloud customers may face legal or regulatory issues, storage costs, or performance degradation.

Lack of role-based access © is not the greatest risk of data leakage in the cloud environment, because it can be mitigated by implementing proper authentication and authorization mechanisms. Role-based access control (RBAC) is a security model that assigns permissions and privileges to users based on their roles and responsibilities. Without RBAC, cloud customers may face unauthorized access, privilege escalation, or data misuse.

Expiration of security certificate (D) is not the greatest risk of data leakage in the cloud environment, because it can be easily detected and renewed. A security certificate is a digital document that verifies the identity and authenticity of a website or service. It also enables secure communication using encryption. If a security certificate expires, it may cause trust issues, warning messages, or connection errors, but not necessarily data leakage.

The first step in an incident response plan is typically preparation12. However, among the options provided, validating the incident would be the first step. This involves confirming that a security event is actually an incident3. It’s important to verify the event to avoid wasting resources on false positives.

An acceptable use policy (AUP) is a preventive control that sets out rules and guidelines for using an organization’s IT resources, including networks, devices, and software1. It defines acceptable and prohibited behaviors, aiming to protect assets, ensure security, and maintain a productive work environment1. By agreeing to and documenting an AUP for the equipment, both organizations can prevent potential misuse of IT resources2345.
