Explanation:
If it is necessary to quickly implement control by applying technical solution that deviates from the company's policies, then risk assessment should be conducted to clarify the risk. It is up to the management to accept the risk or to mitigate it.
Incorrect Answers:
A: As in this case it is important to mitigate the risk, hence risk professional should once recommend a risk assessment. Though the decision for the conduction of risk assessment in case of violation of company's policy, is taken by management.
B: The recommendation to revise the current policy should not be triggered by a single request.
D: Risk professional can only recommend the risk assessment if the company's policies is violating, but it can only be conducted when the management allows.

A managed security service provider (MSSP) is a third-party entity that offers network security services to an organization, such as firewall operation, administration, monitoring, and maintenance1. A firewall is a device or software that controls the incoming and outgoing network traffic based on predefined rules2. A firewall administrator is a person or entity that manages and maintains the firewall configuration, rules, and policies3. When an organization uses an MSSP as a firewall administrator, the greatest concern is the exposure of log data, because log data contains sensitive and valuable information about the organization's network activity, such as source and destination IP addresses, ports, protocols, timestamps, and user identities4. If the log data is not protected properly by the MSSP, it could be accessed, modified, or stolen by unauthorized parties, such as hackers, competitors, or regulators, which could result in data breaches, compliance violations, reputational damage, or legal liabilities for the organization5. The other options are not as concerning as the exposure of log data, because they do not pose a direct and immediate threat to the organization's data security and privacy, but rather affect the quality and efficiency of the firewall management, as explained below:
* B. Lack of governance is a concern when an organization uses an MSSP as a firewall administrator, because it could lead to misalignment or inconsistency between the organization's and the MSSP's objectives, policies, and standards for firewall management. However, this concern can be mitigated by establishing a clear and comprehensive service level agreement (SLA) with the MSSP, which defines the roles, responsibilities, expectations, and performance indicators for the firewall management service6.
* C. Increased number of firewall rules is a concern when an organization uses an MSSP as a firewall administrator, because it could create complexity, confusion, or duplication in the firewall configuration, which could affect the firewall performance and security. However, this concern can be mitigated by conducting regular firewall audits and reviews with the MSSP, which can help to rationalize, optimize,
* and update the firewall rules, and to ensure that they are relevant, effective, and efficient for the organization's network environment.
* D. Lack of agreed-upon standards is a concern when an organization uses an MSSP as a firewall administrator, because it could result in gaps or weaknesses in the firewall design and implementation, which could compromise the firewall functionality and security. However, this concern can be mitigated by adopting and following industry best practices, norms, and expectations for firewall management, such as the National Institute of Standards and Technology (NIST) guidelines, the Center for Internet Security (CIS) benchmarks, or the Payment Card Industry Data Security Standard (PCI DSS) requirements .

Introducing recovery control procedures is the best way to address the risk of an outage of the fraud detection system for an online payment processor, because it helps to restore the functionality and availability of the system as quickly and effectively as possible, and to minimize the impact and disruption to the business operations and customers. A fraud detection system is a system that monitors and analyzes the transactions and activities of an online payment processor, and detects and prevents any fraudulent or suspicious behavior, such as identity theft, money laundering, or chargebacks. An outage is a situation where the system is unavailable or inaccessible, due to factors such as technical failure, human error, or malicious attack. An outage of the fraud detection system may have severe consequences for the online payment processor, such as financial losses, reputational damage, customer dissatisfaction, or regulatory penalties. A recovery control procedure is a procedure that defines the steps and actions to be taken to recover the system from an outage, such as identifying the root cause, isolating the affected components, restoring the data and functionality, testing the system, and reporting the incident. Introducing recovery control procedures is the best way to address the risk, as it helps to ensure that the system is back online and operational as soon as possible, and that the risk exposure and impact are reduced and contained. Implementing continuous control monitoring, communicating the risk to management, and documenting a risk response plan are all possible ways to address the risk, but they are not the best way, as they do not directly address the recovery of the system from an outage, and they may not be sufficient or effective to mitigate the risk.
