A risk assessment indicates the residual risk associated with a new bring your own device (BYOD) program is within organizational risk tolerance. This means that the potential benefits of BYOD outweigh the potential risks, and that the controls in place are adequate to mitigate those risks.
The next step for the risk practitioner is to identify log sources to monitor BYOD usage and risk impact. Log sources are records of events or activities that occur in a system or network, such as file access, network traffic, user behavior, etc. Log sources can provide valuable information about how BYOD devices are used, what data they access, what applications they run, what threats they encounter, etc.
By monitoring log sources, the risk practitioner can track and measure the actual performance and security of BYOD devices, compare them with the expected outcomes and standards, identify any deviations or anomalies that may indicate a breach or a vulnerability, and take appropriate actions to address them.
Therefore, identifying log sources to monitor BYOD usage and risk impact is a recommended action after a successful risk assessment.

Contractually obligating the supplier to follow privacy laws is the best way to mitigate the risk of violating privacy laws when transferring personal information to a supplier, because it ensures that the supplier is legally bound to comply with the applicable laws and regulations that protect the privacy and security of the personal information. This also creates a clear accountability and liability for the supplier in case of a privacy breach, and defines the rights and obligations of both parties in relation to the personal information. The other options are not the best ways to mitigate the risk of violating privacy laws, although they may also be helpful in reducing the likelihood or impact of a privacy breach. Encrypting the data while in transit to the supplier, requiring independent audits of the supplier's control environment, and utilizing blockchain during the data transfer are examples of technical or assurance controls that aim to protect the confidentiality, integrity, and availability of the personal information, but they do not address the legal or contractual aspects of the privacy laws.

The most comprehensive input to the risk assessment process specific to the effects of system downtime is the business impact analysis (BIA). The BIA is a process of analyzing the potential impacts of disruptive events on the business processes, functions, and resources. The BIA identifies the criticality, dependencies, recovery priorities, and recovery objectives of the business processes, and quantifies the financial and non-financial impacts of system downtime. The BIA provides valuable information for the risk assessment process, as it helps to evaluate the likelihood and impact of the risks, and to determine the appropriate risk responses.
Business continuity plan (BCP) testing results, recovery time objective (RTO), and recovery point objective (RPO) are not as comprehensive as the BIA, as they are derived from the BIA and focus on specific aspects of the business continuity and recovery strategies.

A risk heat map is a graphical tool that displays the risk events in a matrix based on their likelihood and impact. Risk events that are coded with the same color will have a similar risk likelihood, which is the probability or frequency of occurrence of a risk event. Risk score, riskimpact, and risk response are other possible attributes of risk events, but they are not represented by the color coding in a risk heatmap.

The best course of action when a new application is added to the environment after testing of the SSO control has been completed is to initiate a retest of the full control, as it may reveal any new issues or gaps that the new application may introduce to the SSO control, and ensure that the control remains effective and adequate.
Retesting the control using the new application as the only sample, reviewing the corresponding change control documentation, and re-evaluating the control during the next assessment are not the best courses of action, as they may not provide sufficient assurance, evidence, or timeliness of the control testing, respectively.
