Azure public-facing Virtual Machines can be secured from brute force attacks with the solution’s ready to use workflows that block attacker IP addresses in the Virtual Machine’s Network Security Groups. The Azure Security Center Alerts types that can be processed automatically are:

*   Suspicious authentication activity
*   Possible incoming SQL brute force attempts detected
*   Web Fingerprint Detected
*   Failed SSH brute force attack

Solution Workflows:

  

**1\. AzureCreateNSGsForNIs**

*   creates NSGs for the Virtual Machines that don't have at least one associated with one of its Network Interfaces
*   (optional) it can be scheduled to run 1st - the other workflows will have no effect froma security resolution point of view if deny security rules cant be created for the attacked VM

**2\. GetAzureSecurityCenterAlerts**

*   gets the Azure Security Center alerts for the supported Brute Force attack types and adds them to an Orchestrator Queue for processing

**3\. AzureVMsAttackersBlock\_AddSecurityRuleToNSG**

*   retrieves the pending Orchestrator queue items 
*   the new Security Rules have their priority computed dynamically
*   if the attacker IP is already blocked in an NSG, it will be skipped

**4\. Block\_AttackerIP\_in\_VM\_NSGs**

*   the workflow can be executed on-demand from the Orchestrator web or mobile apps
*   the specified IP is blocked in all the Network Security Groups associated with the input Virtual Machine

Workflow Solution built on top of the official UiPath IT Automation activities for automating the resolution of Azure brute force attacks security incidents targeting public facing virtual machines.
