 # Provide security contact details in Azure Security Center
 Azure Security Center will recommend that you provide security contact details for your Azure subscription if you haven’t already. This information will be used by Microsoft to contact you if the Microsoft Security Response Center (MSRC) discovers that your customer data has been accessed by an unlawful or unauthorized party. MSRC performs select security monitoring of the Azure network and infrastructure and receives threat intelligence and abuse complaints from third parties.
