Data Encryption

Set up Azure Storage Service Encryption or Azure Disk Encryption to encrypt data at rest for all Azure-stored data.

• The Azure Storage Service Data in Azure storage services is automatically encrypted at rest to give an extra layer of security.
• Data stored in Azure storage services is shielded from unwanted access and potential data breaches by SSE, which makes sure that the data is encrypted at rest.
• SSE eliminates the need for users to manually implement and manage encryption mechanisms. 

When transferring data between applications and Azure services, use SSL or TLS to implement encryption in transit.

Use Azure Information Protection to categorize and tag sensitive data and implement encryption and access policies.

Use Azure Disk Encryption, Azure Storage Service Encryption, and Azure SQL Database Transparent Data Encryption to encrypt the disks of virtual machines. 

Encryption keys, secrets, and certificates can be securely stored and managed using the Azure Key Vault.

Utilize Azure Information Protection to categorize and label sensitive data, limit access, and automatically encrypt it.

Implement Azure DLP policies to identify and stop the unauthorized or accidental sharing of sensitive information.

Database Security

Secure your Storage Account using Management Plane Security using Azure role-based access control (Azure RBAC).

Use Transport-Level Encryption for Azure File Shares by utilizing HTTPS and the encryption provided by SMB 3.0.

When you need complete control over the encryption keys, use client-side encryption to protect the data you send to storage accounts.

Store and manage cryptographic keys, secrets, and certificates in a secure manner using Azure Key Vault.

To automatically encrypt data in Azure Storage, use Storage Service Encryption (SSE), and to encrypt virtual machine disk files for the OS and data disks, use Azure Disk Encryption for Linux VMs or Azure Disk Encryption for Windows VMs.

You can see if users have used a Shared Access Signature or the storage account keys by using Azure Storage Analytics to track the authorization type, similar to how Blob Storage allows you to do it. 

Security Governance and Compliance

Recognize and follow any applicable compliance standards and rules for your sector, such as GDPR, HIPAA, or PCI DSS.

Review Azure compliance documentation frequently to make sure it complies with the standards set by your company.

Give users access to MFA (multi-factor authentication).

Single sign-on (SSO), multiple-factor authentication (MFA), and conditional access policies are available features.

Ensure PIM can manage and track access to privileged roles, which calls for just-in-time access and approval workflows.

Implement robust password policies, MFA, and Azure AD Identity Protection to identify and reduce identity-related risks.

Applications like Microsoft Security Development Lifecycle (SDL) use secure identity capabilities.

Utilize Azure AD Premium anomaly reports and the identity protection features of Azure AD to actively monitor suspicious activity.

Protect Network Resources

Network-capable devices can communicate using TCP/IP by connecting virtual network interface cards to a virtual network.

Managing essential network services like IP addressing, virtual network and subnet provisioning, and ExpressRoute

ExpressRoute, a virtual network appliance feature and IP addressing administration are all part of network security. 

You can see your network and security if you use a shared set of management tools to monitor them. 

A simple, unified security strategy lowers errors because it improves both human comprehension and the dependability of automation.

Secure Cloud Applications

Put into practice secure coding techniques like input validation, secure session management, and frequent security code reviews.

To isolate and secure web applications, use ASE, which offers dedicated network connectivity and improved security controls.

To defend web applications against frequent flaws and attacks, use Azure WAF.

Utilize the Security Center to secure your cloud applications through continuous monitoring, threat detection, and recommendations.

Threat Detection and Monitoring
