Multi-cloud strategies involve using cloud services from more than one vendor. Integrating these services with existing on-premises infrastructure can be challenging from a security standpoint. Security Operations Analysts need to ensure consistent security postures across all environments.
Effective multi-cloud and on-premises integration begins with Cloud Security Posture Management. CSPM tools provide visibility across cloud environments and help enforce security standards. They allow the Security Operations Analyst to:
One of the tools recommended for CSPM is Azure Security Center, which provides a unified security management system that strengthens the security posture of data centers, and hybrid cloud workloads.
Securely connecting multi-cloud and on-premises resources often involves setting up a hybrid network that includes both private connections and public internet pathways. Azure VPN Gateway and Azure ExpressRoute are two services that facilitate secure connectivity:
On-Premises | Azure | AWS or other Cloud |
---|---|---|
VPN Gateway | Virtual Network | VPC (Virtual Private Cloud) |
Direct Connect | ExpressRoute | Direct Connect (AWS) |
Security Information and Event Management (SIEM) tools are vital for monitoring and managing security across multi-cloud and on-premises resources. Microsoft’s Azure Sentinel is an example of a SIEM that can collect data across all these sources, providing security analysts with a comprehensive view of the security state and enabling effective incident response.
Key features of Azure Sentinel include:
In multi-cloud and on-premises infrastructures, maintaining strict control over identities and access is fundamental. Azure Active Directory (Azure AD) can be extended across multi-cloud environments to manage user permissions and ensure that only authorized individuals can access sensitive resources.
IAM Best Practices:
To demonstrate the practical applications of these concepts, consider the following scenarios:
Scenario 1 – Threat Detection Across Multiple Clouds:
A company uses Azure and AWS for different aspects of its operations. By implementing Azure Sentinel, the company can collect security data from both cloud platforms and apply analytics to detect potential threats across both environments.
Scenario 2 – Seamless Identity Management:
An organization with Azure and Google Cloud Platform (GCP) resources wants to simplify user access. By using Azure AD B2C, they can manage customers’ identities regardless of the cloud platform, ensuring a unified identity management system.
In conclusion, connecting multi-cloud and on-premises resources securely is a complex but crucial task for Security Operations Analysts. The key to success in this area lies in effectively using CSPM tools, establishing secure connectivity, managing identities with IAM frameworks, and leveraging SIEM systems to monitor security across environments. Candidates preparing for the SC-200 exam should familiarize themselves with these strategies and tools to demonstrate proficiency in securing a hybrid and multi-cloud infrastructure.
Azure Arc extends Azure’s management capabilities to resources located outside of Azure, whether on-premises, in other clouds, or at the edge.
Answer: A, C, D
Azure Arc enables multi-cloud and hybrid management. Azure Sentinel (now Microsoft Sentinel) provides security information and event management across environments. Azure Virtual Network enables Azure services to securely connect with on-premises networks.
Azure Security Center (now part of Microsoft Defender for Cloud) provides security recommendations across on-premises, Azure, and multi-cloud resources.
Answer: B
Azure Active Directory provides identity services that can manage and secure access to cloud applications in multi-cloud and on-premises environments.
Azure VPN Gateway connects on-premises networks to Azure through Site-to-Site VPNs, making it part of a secure connection between multi-cloud and on-premises environments.
Answer: B
Microsoft Sentinel (formerly Azure Sentinel) provides SIEM and SOAR functionalities in the cloud and can be integrated with on-premises and multi-cloud resources.
Answer: A
Azure ExpressRoute provides a private, high-bandwidth connection that is dedicated to connecting Azure datacenters with on-premises infrastructure, bypassing the public internet.
Microsoft Cloud App Security is a Cloud Access Security Broker (CASB) that offers visibility and control over data travel and sophisticated analytics to identify and combat cyber threats across multi-cloud environments.
Answer: B
Azure Arc allows you to extend Azure management and governance capabilities to anywhere, enabling deployment and management of Azure services across on-premises, multi-cloud, and edge environments.
Azure Sentinel can integrate with various cloud providers, including AWS, allowing for centralized monitoring and management of security data across multi-cloud environments.
Answer: A
Microsoft Intune is used for device management and application protection across multiple device platforms, which can include devices used in a multi-cloud environment.
Azure Bastion is a service that provides secure and seamless RDP and SSH access to virtual machines directly in the Azure portal without the need for public IP addresses on the VMs.
Microsoft Azure Security Center is a unified security management system that provides threat protection across on-premises, multi-cloud, and hybrid cloud workloads.
You can connect your AWS resources with Microsoft Azure Security Center by following the Quickstart onboarding process, which involves creating an AWS Identity and Access Management (IAM) role and running a script in the AWS Management Console.
By connecting your AWS resources with Microsoft Azure Security Center, you can gain centralized visibility and management of your security posture across your entire cloud environment, including AWS, Microsoft Azure, and on-premises workloads.
GCP (Google Cloud Platform) is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products.
You can connect your GCP resources with Microsoft Azure Security Center by following the Quickstart onboarding process, which involves creating a service account and a JSON key file, and then entering the key file information into the Azure portal.
By connecting your GCP resources with Microsoft Azure Security Center, you can gain centralized visibility and management of your security posture across your entire cloud environment, including GCP, Microsoft Azure, and on-premises workloads.
Microsoft Azure Security Center can collect logs and events from AWS CloudTrail and GCP Cloud Audit Logs, respectively.
CloudTrail is an AWS service that provides a record of API calls made in your AWS account.
Cloud Audit Logs are a feature of GCP that provide an audit trail of activity in your GCP project, including API calls, configuration changes, and data access.
Microsoft Azure Security Center uses the data collected from AWS CloudTrail and GCP Cloud Audit Logs to identify security risks and provide recommendations for improving your security posture.
Yes, Microsoft Azure Security Center supports onboarding of other cloud platforms using partner solutions.
A partner solution is a third-party application or service that integrates with Microsoft Azure Security Center to provide additional security features and functionality.
You can enable data collection for on-premises resources in Microsoft Azure Security Center by deploying the Microsoft Monitoring Agent on each on-premises server.
The Microsoft Monitoring Agent can collect logs, performance data, and security-related events from on-premises resources.
Microsoft Azure Security Center uses the data collected from on-premises resources to identify security risks and provide recommendations for improving your security posture.
