1. Host-level Security
-
Secure the host operating system: Apply latest security patches and updates regularly. Importance: Critical
-
Implement strong authentication: Use complex passwords and consider multi-factor authentication for host access. Importance: High
-
Enable and configure Windows Defender: Ensure real-time protection is active on the host. Importance: High
-
Configure Windows Firewall: Restrict incoming and outgoing traffic to only necessary ports and services. Importance: High
2. Network Security
-
Isolate management traffic: Use separate networks for VM traffic, storage traffic, and management. Importance: High
-
Implement VLANs: Use virtual LANs to segment network traffic between different VM groups. Importance: Medium
-
Enable encryption for live migration: Use Kerberos or CredSSP for authentication during live migrations. Importance: High
3. Virtual Machine Security
-
Use Generation 2 VMs: They provide better security features like Secure Boot and UEFI. Importance: Medium
-
Enable virtual TPM: This allows for BitLocker encryption within VMs. Importance: High
-
Keep VMs updated: Regularly patch and update the guest operating systems. Importance: Critical
-
Use VM snapshots cautiously: They can contain sensitive data and should be managed securely. Importance: Medium
4. Access Control and Monitoring
-
Implement Role-Based Access Control (RBAC): Limit administrative access based on job roles. Importance: High
-
Enable auditing: Monitor and log access to Hyper-V hosts and management tools. Importance: High
-
Use System Center Virtual Machine Manager (SCVMM): For centralized management and monitoring of large Hyper-V environments. Importance: Medium
5. Storage Security
-
Encrypt storage: Use BitLocker to encrypt volumes hosting VM files. Importance: High
-
Implement shielded VMs: For highly sensitive workloads, use shielded VMs to protect against host admin access. Importance: High (for sensitive data)
Note: The importance levels provided are general guidelines. The specific importance of each practice may vary depending on your organization's security requirements and risk assessment.
