Microsoft Defender for Cloud, previously known as Azure Security Centre, is an advanced security solution from Microsoft designed to protect cloud-based systems and data hosted on the Microsoft platform. This comprehensive cloud security solution leverages artificial intelligence and deep learning algorithms to detect malicious activity, prevent data breaches and other cyber threats, and secure corporate networks from external attacks.
Microsoft Defender for Cloud uses sophisticated heuristic technologies such as behavioural analytics, machine learning, and traditional signature-based detection to identify suspicious activities in real time. It also offers visibility into the attack surface of your cloud environment with a unified view of threats across all workloads including virtual machines, storage accounts, web applications, databases, serverless computing resources, containers and more. Furthermore, it features automated incident response capabilities that allow organizations to quickly respond to any detected threats efficiently without manual intervention.
Benefits of Microsoft Defender for Cloud
Microsoft Defender for Cloud is an advanced threat protection solution designed to secure cloud infrastructures. It provides comprehensive end-to-end protection, including endpoint detection and response, identity and access management, security analytics and real-time threat intelligence. With Microsoft Defender for Cloud, organizations can protect their critical data with advanced defences against cyber criminals.
Organizations can benefit from the automated vulnerability assessments provided by Microsoft Defender for Cloud which helps identify potential threats before they become a problem. The platform also provides powerful insights into malicious activity in order to quickly detect and respond to any suspicious events. Additionally, it includes integrated identity and access management capabilities that allow organizations to securely connect users to their cloud resources with the least privileged access.
Furthermore, Microsoft Defender for Cloud offers advanced analytics tools that provide visibility into user activities in order to detect anomalies or suspicious behaviour.
How does Defender for Cloud detect threats?
Microsoft security researchers are constantly on the lookout for threats. Because of our global presence in the cloud and on-premises, we have access to an expansive set of telemetry. The wide-reaching and diverse collection of datasets enables us to discover new attack patterns and trends across our on-premises consumer and enterprise products, as well as our online services. As a result, Defender for Cloud can rapidly update its detection algorithms as attackers release new and increasingly sophisticated exploits.
This approach helps you keep pace with a fast-moving threat environment. To detect real threats and reduce false positives, Defender for Cloud collects, analyses, and integrates log data from your Azure resources and the network. It also works with connected partner solutions, like firewall and endpoint protection solutions. Defender for Cloud analyses this information, often correlating information from multiple sources, to identify threats.
Two broad pillars of cloud security:
Cloud Security Posture Management (CSPM) – In Defender for Cloud, the posture management features provide:
- Visibility – to help you understand your current security situation
- Hardening guidance – to help you efficiently and effectively improve your security
On the Security posture page, you’re able to see the secure score for your entire subscription and each environment in your subscription. By default, all environments are shown
Cloud Workload Protection (CWP) – Defender for Cloud offers security alerts that Microsoft Threat Intelligence powers. It also includes a range of advanced, intelligent protections for your workloads.
Organizations have to secure their data and applications with the right security solutions. Cloud workload protection is a vital component of the overall security strategy that provides visibility, control and automation across workloads, platforms and clouds. With cloud workload protection, organizations can protect their sensitive information from malicious actors while ensuring compliance with industry standards.
Defender for Cloud provides comprehensive protection against threats targeting your cloud environment by leveraging advanced analytics capabilities to detect malicious activities. Its advanced security features such as application whitelisting, system hardening, user behavior monitoring and anomaly detection help you reduce your risk profile without impacting performance or availability. It also offers continuous monitoring of your public cloud services by providing alerts when suspicious activities are detected in real-time. This allows for swift action to be taken when a threat is detected and mitigated before it causes any damage or disruption in operations.
Microsoft Defender for Cloud, brings advanced, intelligent protection to your Azure and hybrid resources and workloads.
Additional Capabilities of Defender for Cloud:
- Hybrid cloud protection
In addition to defending your Azure environment, you can add Defender for Cloud capabilities to your hybrid cloud environment:
- Protect your non-Azure server
- Protect your virtual machines in other clouds (such as AWS and GCP)
You’ll get customized threat intelligence and prioritized alerts according to your specific environment so that you can focus on what matters the most.
To extend protection to virtual machines and SQL databases in other clouds or on-premises, deploy Azure Arc and enable Defender for Cloud. Azure Arc for servers is a free service, but services used on Arc enabled servers, such as Defender for Cloud, will be charged as per the pricing for that service. Learn more in Add non-Azure machines with Azure Arc.
- Microsoft Defender for Cloud security alerts:
When Defender for Cloud detects a threat in any area of your environment, it generates a security alert. These alerts describe details of the affected resources, suggested remediation steps, and in some cases, an option to trigger a logic app in response.
Whether an alert is generated by Defender for Cloud or received by Defender for Cloud from an integrated security product, you can export it. To export your alerts to Microsoft Sentinel, any third-party SIEM, or any other external tool, follow the instructions in Stream alerts to a SIEM, SOAR, or IT Service Management solution.
- Microsoft Defender for Cloud advanced protection capabilities
Defender for Cloud uses advanced analytics for virtual machines, SQL databases, containers, web applications, your network, and more. Protections include securing the management ports of your VMs with just-in-time access, and adaptive application controls to create allowlists for what apps should and shouldn’t run on your machines.
- Vulnerability assessment and management:
Defender for Cloud includes vulnerability scanning for your virtual machines and container registries at no extra cost. The scanners are powered by Qualys, but you don’t need a Qualys license or even a Qualys account – everything’s handled seamlessly inside Defender for Cloud.
Review the findings from these vulnerability scanners and respond to them all from within Defender for Cloud. This capability brings Defender for Cloud closer to being the single pane of glass for all of your cloud security efforts.
