Knowing the areas in your API lifecycle that are insecure is the first step to securing them. Testing the Logic App exposed to Azure API Management. However, it’s important to be mindful of authorized users when practicing best practices. The attacker receives a "403 unauthorized access" exception, and the connection is closed. It is an extremely effective way to provide a layer of abstraction between your callers and back-end APIs, and provides centralised governance across your API surface. You may also send NSG flow logs to a Log Analytics workspace and use Traffic Analytics to provide insights into traffic flow in your Azure cloud. Ensure that there are written incident response plans that define all roles of personnel as well as phases of incident handling/management from detection to post-incident review. Verbosity of the logging can be configured on a service-wide and per-API basis. Use a single API Management resource for exposing all APIs to both internal consumers and external consumers. By specifying the service tag name (e.g., ApiManagement) in the appropriate source or destination field of a rule, you can allow or deny the traffic for the corresponding service. Configure advanced monitoring with API Management by using the log-to-eventhub policy, capture any additional context information required for security analysis, and send to Azure Sentinel or third-party SIEM.
