Overview Azure Information Protection enables you to discover, classify, label, and protect sensitive information using built-in information types and custom regexes. While our built-in sensitive information types cover a broad range of information, such as financial data, PII, and health-care data, a common request has been to be able to detect credential information. This request is hardly surprisingly since the security of your data often depends on the integrity of credentials such as secret keys, passwords, and certificates, which are used for authentication and authorization. Often, poorly secured credentials are the root cause of a security breach and data loss.   Azure Information Protection can now detect different types of credentials Today we’re announcing the public preview of the first group of credentials that AIP can automatically detect. The following credentials types can now be discovered by both Azure Information Protection client and the Azure Information Protection scanner: Azure Service Bus Connection String Azure IoT Connection String Azure Storage Account Azure IAAS Database Connection String and Azure SQL Connection String Azure Redis Cache Connection String Azure SAS SQL Server Connection String Azure DocumentDB Auth Key Azure DocumentDB Auth Key Azure Publish Setting Password Azure Storage Account Key (Generic) Getting Started You can help your end-users be more compliant with your credentials handling policy. For example, if an end-user copies a connection string from a configuration file to their Excel or Word document, you can use conditions defined for your sensitivity labels to either recommend to your users that they should avoid storing passwords in unprotected Office files, or that they should protect the files with AIP, or you can automatically protect the files that contain credentials.   Figure 1: Recommendation defined by an admin when credentials are detected   Figure 2: Resulting end user experience when SQL connection string is copied from a web.config file   You can further use the Azure Information Protection scanner to detect these credentials in on-premises file repositories, and then take action based on the generated reports. In addition to detecting these credentials, you can use the scanner to automatically protect files that contain credentials. Keep in mind that credentials can be stored in files with non-standard file name extensions. The Azure Information Protection scanner uses IFilters to extract file content and match content. You can link the built-in text IFilter to non-standard file name extensions to enable the scanner to inspect these files. To learn more about IFilters and how to map them to file name extensions see our Registering Filter Handlers documentation.  You can then use Azure Information Protection analytics and discovery to review the scanning results.   Figure 3: Example Discovery report showing detected credentials   Microsoft IT protects credential information using Azure Information Protection The new credential information types was one of the main use cases for Azure Information Protection scanner implementation in Microsoft. In conjunction with information about the last modified date of the file, it helped Microsoft IT evaluate the risk of credentials stored in files. The owner / editor of files reported by the scanner helped IT contact the right person to remove credentials from their files and change the exposed credentials used in applications, systems and services. Looking forward Introducing these credentials sensitive info types in Azure Information Protection is just the first step in helping you secure your credentials. We are expecting these patterns to become gradually available across other Microsoft Information Protection services, like Microsoft Cloud App Security and Office 365 DLP. More information types are planned to be released later and to be extended beyond the current list of Azure credentials.
