📦Secure Your Azure Data Lake Storage Gen2
Security Risk Items and Control Recommendations for Azure Data Lake Storage Gen2
Unauthorized Access to Data
Risk: Unauthorized users may gain access to sensitive data stored in Azure Data Lake Storage Gen2.
Control Recommendation:
Implement role-based access control (RBAC) to ensure only authorized users have access to data.
Use Azure Active Directory (AAD) for user authentication and authorization.
Regularly review and audit access permissions.
Data Leakage and Exfiltration
Risk: Data might be leaked or exfiltrated by malicious insiders or external attackers.
Control Recommendation:
Enable data encryption at rest using Azure Storage Service Encryption (SSE).
Use Azure Key Vault to manage and safeguard encryption keys.
Implement network security controls such as virtual network service endpoints and private endpoints to restrict data access.
Insufficient Logging and Monitoring
Risk: Lack of proper logging and monitoring can delay the detection of security incidents.
Control Recommendation:
Enable Azure Storage Analytics to monitor and log access to the data lake.
Use Azure Monitor and Azure Security Center for comprehensive monitoring and alerting on suspicious activities.
Implement Azure Sentinel for advanced threat detection and incident response.
Data Integrity Compromise
Risk: Unauthorized changes to data can compromise data integrity.
Control Recommendation:
Implement Azure Data Lake Storage's immutable storage feature to protect critical data from being altered or deleted.
Use checksums and data validation techniques to ensure data integrity.
Regularly back up data and use versioning to maintain historical copies of data.
Insecure Data Transmission
Risk: Data might be intercepted during transmission if not properly encrypted.
Control Recommendation:
Use HTTPS for all data transmissions to ensure data is encrypted in transit.
Enforce secure transfer requirements on the storage account.
Implement VPNs or ExpressRoute for secure communication between on-premises infrastructure and Azure.
Misconfiguration of Storage Accounts
Risk: Misconfiguration of storage accounts can lead to unintended data exposure or vulnerabilities.
Control Recommendation:
Regularly review and update storage account configurations based on best practices.
Use Azure Policy to enforce compliance with organizational policies and standards.
Conduct regular security assessments and configuration audits.
Inadequate Data Access Governance
Risk: Lack of proper governance can lead to unauthorized data access and misuse.
Control Recommendation:
Implement data access governance policies using Azure Purview to manage and govern data access.
Define and enforce data classification and labeling.
Conduct periodic reviews of data access policies and procedures.
Denial of Service (DoS) Attacks
Risk: DoS attacks can disrupt access to data and services.
Control Recommendation:
Use Azure DDoS Protection to safeguard against distributed denial-of-service (DDoS) attacks.
Implement rate limiting and throttling to control the rate of requests.
Monitor for unusual spikes in traffic and automate responses to potential DoS attacks.
Insecure API Access
Risk: Insecure APIs can be exploited to gain unauthorized access to data.
Control Recommendation:
Secure APIs with OAuth 2.0 and Azure Active Directory (AAD) authentication.
Use Azure API Management to secure, monitor, and manage API traffic.
Regularly review and update API security configurations.
Lack of Data Backup and Recovery Planning
Risk: Failure to properly back up data can lead to data loss in case of a disaster.
Control Recommendation:
Implement a comprehensive backup strategy using Azure Backup.
Regularly test data recovery processes to ensure they are effective.
Store backups in geographically redundant locations to ensure availability.
