Azure Defender for Cloud: Comprehensive Security for Your Cloud Infrastructure

Azure Defender for Cloud is a comprehensive security solution designed to protect your cloud infrastructure from various threats. It's a unified security posture management solution that integrates with Azure Security Center to provide real-time threat protection and vulnerability assessment.

With Azure Defender for Cloud, you can monitor and analyze your cloud resources in real-time, detecting potential security risks before they become major issues. This proactive approach helps prevent data breaches and ensures the integrity of your cloud environment.

Azure Defender for Cloud is available for various cloud platforms, including Azure, AWS, and GCP, allowing you to secure your multi-cloud environment with a single solution. It's also highly scalable, making it suitable for businesses of all sizes and complexity levels.

Azure Defender for Cloud provides robust threat detection and response capabilities to secure your cloud environment. It continuously monitors your cloud resources and network traffic in real-time, employing advanced analytics and machine learning to identify suspicious activities and potential threats.

Threat Analytics report for containers is a dedicated report designed to provide comprehensive visibility into threats targeting containerized environments. It equips SOC teams with insights to detect and respond to the latest attack patterns on AKS, EKS, and GKE clusters.

With agentless malware detection, new security alerts are triggered when malicious files are detected in AKS nodes. The Microsoft Defender Antivirus anti-malware engine scans and detects malicious files, directing security alerts into Defender for Cloud and Defender XDR for investigation and remediation.

Azure Defender for Cloud responds swiftly to detected threats, taking necessary actions to mitigate the risk. This could include alerting your security team, quarantining affected resources, or blocking malicious traffic.

Here are the key features of the Threat Analytics report for containers:

Azure Defender for Cloud provides a comprehensive set of security features and capabilities that enable you to secure your cloud workloads and applications. It offers a single-pane-of-glass view of your cloud security posture, making it easier to monitor and manage security across multiple cloud platforms.

With advanced analytics and machine learning, Azure Defender for Cloud detects and blocks potential threats in real-time. It continuously learns from security events and incidents, enabling it to improve its threat detection and response capabilities over time.

The solution generates real-time alerts, providing your security team with immediate visibility into security incidents. These alerts include information about the nature of the threat, affected resources, and recommended actions. Automation capabilities enable you to orchestrate responses, ensuring that threats are contained and mitigated swiftly.

Azure Defender for Cloud offers robust security scanning and monitoring capabilities to protect your cloud resources. You can initiate on-demand malware scanning in Microsoft Defender for Storage, which uses the latest malware definitions and provides upfront cost estimation.

This feature can be initiated from the Azure portal UI or via the REST API, making it easy to automate through Logic Apps, Automation playbooks, and PowerShell scripts. Incident response, security baseline, and compliance are just a few use cases for this feature.

Azure Defender for Cloud also provides vulnerability assessment for your cloud resources, identifying potential vulnerabilities in configurations, applications, and operating systems. These vulnerabilities are categorized and prioritized based on severity, giving your IT and security teams valuable insights into what needs immediate attention.

Here are some use cases for vulnerability assessment:

Azure Defender for Cloud provides vulnerability assessment capabilities to identify potential vulnerabilities in your cloud resources. It regularly scans your configurations, applications, and operating systems to categorize and prioritize vulnerabilities based on their severity.

You can review and remediate vulnerabilities and CVEs found on Azure Kubernetes Service (AKS) nodes through the new recommendation available in the Azure portal. This recommendation is titled "AKS nodes should have vulnerability findings resolved".

Azure Defender for Cloud identifies vulnerabilities before they're exploited, reducing the attack surface and enhancing your overall security posture. It provides valuable insights into what needs immediate attention, equipping your IT and security teams to address critical vulnerabilities.

To receive vulnerability assessment capabilities, you need to enable the agentless scanning for machines option in the Defender CSPM, Defender for Containers, or Defender for Servers P2 plan in your subscription. This allows you to maintain security and compliance across the managed Kubernetes service.

Agentless Code Scanning offers fast and scalable security for all repositories in Azure DevOps organizations with one connector.

You can securely monitor all repositories in Azure DevOps organizations with one connector, making it easy to keep track of your code and infrastructure as code (IaC) configurations.

Early vulnerability detection is key to proactive risk management, and Agentless Code Scanning helps you quickly find code and IaC risks.

Continuous security insights are essential to keeping visibility and responding quickly across development cycles without affecting productivity.

Here are the benefits of Agentless Code Scanning in Microsoft Defender for Cloud:

On-Demand Malware Scanning is a game-changer for Azure Storage accounts. Starting in public preview, you can initiate scans from the Azure portal UI or via the REST API, supporting automation through Logic Apps, Automation playbooks, and PowerShell scripts.

This feature uses Microsoft Defender Antivirus with the latest malware definitions for every scan, providing a high level of security. You can initiate scans for specific storage accounts after detecting suspicious activity, or scan all stored data when first enabling Defender for Storage.

Incident response, security baseline, and compliance are just a few examples of how On-Demand Malware Scanning can be used. Here are some specific use cases:

Keep in mind that for storage accounts where large blobs are uploaded, the increased blob size limit will result in higher monthly charges. Be sure to set an appropriate cap on total GB scanned per month to avoid unexpected high charges.

File Integrity Monitoring is now available in public preview as part of Defender for Servers Plan 2, based on Microsoft Defender for Endpoint.

This new version enables you to monitor file integrity and detect potential security threats.

The FIM experience over AMA is no longer available in the Defender for Cloud portal.

You can still use the FIM experience over MMA until the end of November 2024.

Starting in September, an in-product experience will be released to help you migrate your FIM configuration over MMA to the new FIM over Defender for Endpoint version.

For more information on how to enable FIM over Defender for Endpoint, see the dedicated guide.

Migrating from previous versions is also covered in a separate guide, so be sure to check that out if you need to upgrade.

Azure Defender for Cloud simplifies compliance by providing tools and insights that help you adhere to industry-specific regulations and standards.

The solution can assist you in meeting your compliance requirements for GDPR, HIPAA, or SOC 2, saving you time and effort.

Compliance is a non-negotiable aspect of business operations, and Azure Defender for Cloud makes it easier to stay on top of regulations.

You can assign the updated CIS standards for managed Kubernetes environments to your AWS/EKS/GKE Kubernetes resources from the regulatory compliance dashboard.

The dashboard offers updated versions of the Center for Internet Security (CIS) standards for assessing the security posture of managed Kubernetes environments.

Here are the updated CIS standards you can assign:

To ensure the best possible depth of coverage for these standards, Azure Defender for Cloud has enriched its coverage by releasing 79 new Kubernetes-centric recommendations.
