Today’s evolving threat landscape calls for a proactive and comprehensive approach to securing cloud infrastructure. Azure IaaS provides robust capabilities through an integrated zero trust principle, ensuring that your resources remain secure against unauthorized access and breaches. By using multi-factor authentication, role-based access control (RBAC), and a conditional access policy, you can verify identities and enforce minimum privileged access. Network segmentation, encryption of data at rest and in transit, and ongoing monitoring through Azure Security Center and Sentinel for additional security Proactive responses, backup mechanisms, and compliance drive security so is greater. Acknowledging the lack of trust in Azure IaaS empowers organizations to embrace the “never trust you, always prove it,” providing a solid and secure foundation for cloud operations.
Improve identity and access management 💻
Principle: Trust no one; Make sure everything is true.
Enable Multi-Factor Authentication (MFA): MFA is required for all Azure accounts, including administrators, to prevent unauthorized access.
Use Conditional Access Policies: Use policies to enforce conditions such as device illegality, location, or user risk before granting access.
Use Role-Based Access Control (RBAC): Assign role-based permissions to ensure minimum privileges.
Identity Protection: Use Azure Active Directory Identity Protection to detect and respond to identity-based threats in real time.
Use safe endpoints 💻
Principle: Assume a violation.
Use Microsoft Defender for endpoints: Implement endpoint protection and monitor threats across virtual machines (VMs).
Implement patching and updates: Regularly update OS and applications to address vulnerabilities.
Endpoint Monitoring: Monitor and log activity on all IaaS resources using Azure Monitor and Azure Security Center.
Protect Data at Rest and In Transit 💻
Principle: Encrypt everything.
Encrypt data: Use Azure Disk Encryption for VMs and enable encryption for storage accounts.
Secure network traffic: Use Azure Virtual Network encryption and enforce HTTPS/TLS for data transfer.
Use Azure Key Vault: Store and maintain cryptographic keys and secrets.
Network segmentation 💻
Principle: Minimize backward movement.
Use Azure Virtual Networks (VNets): Create distributed VNets for different projects and enforce isolation through network security groups (NSGs).
Use Azure Firewall: Use Azure Firewall for centralized network security policies and traffic filtering.
Micro-partitioning: Implement micro-partitioning techniques through Network Security and Azure Application Gateway.
Continuous assessment and risk identification 💻
Principle: Make sure it is clear and consistent.
Enable Azure Security Center: View security recommendations and threat alerts for Azure products.
Deploy Azure Sentinel: Use this SIEM solution for proactive threat detection and response.
Set up log analysis: Collect and analyze logs from all Azure objects to identify anomalies.
Threat Reporting: Use the integrated threat reporting feeds in Azure Defender.
Application Security 💻
Principle: Protect the project.
Use web application firewalls (WAFs): Use Azure WAF to protect applications from web vulnerabilities.
DevOps Security Practices: Add security testing to CI/CD pipelines using Azure DevOps.
Scan for vulnerabilities: Use Defender for Cloud to regularly scan Azure products and applications for vulnerabilities.
Government and Rule of Law 💻
Principle: Take responsibility.
Establish policy: Use Azure Policy to enforce organizational standards and compliance.
Audit Factors: Monitor and review configuration reviews on a regular basis through Azure Blueprints and Compliance Manager.
User Management Analysis: Monitor and monitor access to Azure resources on a periodic basis.
Automate the answers 💻
Principle: Provide feedback in real time.
Set up the playbook: Use Azure Logic Apps and the Security Center playbook to create a proactive response to the issue.
Enable auto-remediation: Automatically fix incorrect security settings or common non-compliance issues.
Incident management: Integrate Azure and ITSM tools to better manage incident workflow.
Backup and disaster recovery 💻
Principle: Plan for failure.
Enable Azure Backup: Back up IaaS VMs, storage, and applications regularly.
Use Azure Site Recovery: Implement disaster recovery plans for critical IaaS workloads.
Test recovery plan: Regularly test disaster recovery plans to ensure business continuity.
By aligning Azure IaaS policies with standard configuration and trust principles, you create a robust and secure environment that can meet today’s threats while maintaining compliant organizational and regulatory requirements.
