Course 29 - AZ-500 Microsoft Azure Security Technologies | Episode 13: Storage, SQL Databases, and HDInsight

A summary of the lesson on securing data in Azure Storage, SQL, and HDInsight:OverviewFocus: Implementing defense-in-depth for data protection across Azure Storage, Azure SQL, and HDInsight.Combines theoretical concepts with practical labs to secure sensitive information and prevent breaches.1. Azure Storage SecurityNetwork SecurityUse firewalls and Virtual Networks (VNets) to restrict access to:Authorized subnetsSpecific IP rangesDefault deny-all rule blocks unauthorized internet traffic.Access ControlThree container permission levels: Private, Blob, ContainerRisks associated with master storage account keysUse Shared Access Signatures (SAS) for time-limited delegated accessRecommendations:Azure AD for centralized access managementAzure AD Domain Services (Azure ADS) for Kerberos authentication with Azure FilesEncryptionIn transit: TLSAt rest:Microsoft-managed keysCustomer-managed keys stored in Azure Key VaultMonitoring and AuditingEnable Diagnostic Logging v2.0 and Storage AnalyticsLogs can be analyzed via Azure Monitor2. Azure SQL Advanced Data SecurityThree main pillars:Data Discovery & Classification: Identify and label sensitive information (e.g., GDPR data)Vulnerability Assessment: Proactively detect and remediate security gapsAdvanced Threat Protection: Detect anomalous activity such as:SQL injectionBrute force attacks3. HDInsight Security (Big Data Analytics)Virtual Networks (VNet): Secure cluster perimeterAzure AD Domain Services (Azure ADS): Synchronize identities for authenticationApache Ranger: Provides:Role-based access control (RBAC)Fine-grained data masking and permissions managementKey TakeawaysApply defense-in-depth at multiple layers: network, access, encryption, monitoringCentralize identity management with Azure AD / Azure ADSUse SAS tokens and customer-managed keys for secure delegationImplement monitoring and logging to detect unauthorized accessExtend best practices to big data platforms like HDInsight with RBAC and data maskingYou can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cybercode_academy
