Correct Answer: DTo assess the security of Azure App Service web apps and Azure functions, one can use the Compute & apps section in Azure Security Center, now known as Microsoft Defender for Cloud. This feature provides a set of recommendations specifically tailored for securing web apps and Azure functions, monitoring their security state, and offering actionable insights to improve security. Other options like Security & Compliance in Azure Log Analytics, Resource health in Azure Service Health, and Smart Detection in Azure Application Insights focus on different aspects such as logging, overall resource health, and performance monitoring, respectively, rather than providing security recommendations.
