      "Id": "LogicApps110",
      "ControlSeverity": "High",
      "Automated": "Yes",
      "MethodName": "CheckLogicAppsInSameRG",
      "Rationale": "API Connections contain critical information like credentials/secrets, etc., provided as part of configuration. Logic App can use all API Connections present in the same Resource Group. Thus, Resource Group should be considered as security boundary when threat modeling.",
      "Recommendation": "Separate Logic Apps into different resource groups unless the apps trust each other and need to use API Connections present in the resource group.",

      "Rationale": "This ensures that connectors can be used only towards intended actions in the Logic App",

      "ControlSeverity": "Medium",
      "Automated": "Yes",
      "MethodName": "CheckRBACAccess",
      "Rationale": "Granting minimum access by leveraging RBAC feature ensures that users are granted just enough permissions to perform their tasks. This minimizes exposure of the resources in case of user/service account compromise.",
      "Recommendation": "Assign 'Logic App Contributor' role to developers and 'Logic App Operator' role to operators. Refer: https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-securing-a-logic-app#secure-access-to-manage-or-edit-logic-apps",

Do not add IP range $($this.ControlSettings.UniversalIPRange) as this means access to all IPs.

      "MethodName": "CheckContentsAccessControl",
      "Rationale": "Using the firewall feature ensures that access to the data or the service is restricted to a specific set/group of clients. While this may not be feasible in all scenarios, when it can be used, it provides an extra layer of access control protection for critical assets.",

      "ControlSeverity": "High",
      "Automated": "Yes",
      "MethodName": "CheckConnectorsSecretsHandling",
      "Rationale": "Keeping secrets such as DB connection strings, passwords, keys, etc. in clear text can lead to easy compromise at various avenues during an application's lifecycle. Storing them in a key vault ensures that they are protected at rest.",
      "Recommendation": "Use 'secureString' type parameter in Logic App code view for secret parameters. Refer: https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-securing-a-logic-app#secure-parameters-and-inputs-within-a-workflow",

      "Rationale": "Periodic key/password rotation is a good security hygiene practice as, over time, it minimizes the likelihood of data loss/compromise which can arise from key theft/brute forcing/recovery attacks.",

      "MethodName": "CheckDiagnosticsSettings",
      "Rationale": "Logs should be retained for a long enough period so that activity trail can be recreated when investigations are required in the event of an incident or a compromise. A period of 1 year is typical for several compliance requirements as well.",
