Protecting Your Azure Key Vault: Why Azure RBAC Is Critical for Security
Introduction In today’s cloud-centric landscape, misconfigured access controls remain one of the most critical weaknesses in the cyber kill chain. When access policies are overly permissive, they create opportunities for adversaries to gain unauthorized access to sensitive secrets, keys, and certificates. These credentials can be leveraged for lateral movement, privilege escalation, and establishing persistent footholds across cloud environments. A compromised Azure Key Vault doesn’t just expose isolated assets it can act as a pivot point to breach broader Azure resources, potentially leading to widespread security incidents, data exfiltration, and regulatory compliance failures. Without granular permissioning and centralized access governance, organizations face elevated risks of supply chain compromise, ransomware propagation, and significant operational disruption. The Role of Azure Key Vault in Security Azure Key Vault plays a crucial role in securely storing and managing sensitive information, making it a prime target for attackers. Effective access control is essential to prevent unauthorized access, maintain compliance, and ensure operational efficiency. Historically, Azure Key Vault used Access Policies for managing permissions. However, Azure Role-Based Access Control (RBAC) has emerged as the recommended and more secure approach. RBAC provides granular permissions, centralized management, and improved security, significantly reducing risks associated with misconfigurations and privilege misuse. In this blog, we’ll highlight the security risks of a misconfigured key vault, explain why RBAC is superior to legacy Access Policies and provide RBAC best practices, and how to migrate from access policies to RBAC. Security Risks of Misconfigured Azure Key Vault Access Overexposed Key Vaults create significant security vulnerabilities, including: Unauthorized access to API tokens, database credentials, and encryption keys. Compromise of dependent Azure services such as Virtual Machines, App Services, Storage Accounts, and Azure SQL databases. Privilege escalation via managed identity tokens, enabling further attacks within your environment. Indirect permission inheritance through Azure AD (AAD) group memberships, making it harder to track and control access. Nested AAD group access, which increases the risk of unintended privilege propagation and complicates auditing and governance. Consider this real-world example of the risks posed by overly permissive access policies: A global fintech company suffered a severe breach due to an overly permissive Key Vault configuration, including public network access and excessive permissions via legacy access policies. Attackers accessed sensitive Azure SQL databases, achieved lateral movement across resources, and escalated privileges using embedded tokens. The critical lesson: protect Key Vaults using strict RBAC permissions, network restrictions, and continuous security monitoring. Why Azure RBAC is Superior to Legacy Access Policies Azure RBAC enables centralized, scalable, and auditable access management. It integrates with Microsoft Entra, supports hierarchical role assignments, and works seamlessly with advanced security controls like Conditional Access and Defender for Cloud. Access Policies, on the other hand, were designed for simpler, resource-specific use cases and lack the flexibility and control required for modern cloud environments. For a deeper comparison, see Azure RBAC vs. access policies. Best Practices for Implementing Azure RBAC with Azure Key Vault To effectively secure your Key Vault, follow these RBAC best practices: Use Managed Identities: Eliminate secrets by authenticating applications through Microsoft Entra. Enforce Least Privilege: Precisely control permissions, granting each user or application only minimal required access. Centralize and Scale Role Management: Assign roles at subscription or resource group levels to reduce complexity and improve manageability. Leverage Privileged Identity Management (PIM): Implement just-in-time, temporary access for high-privilege roles. Regularly Audit Permissions: Periodically review and prune RBAC role assignments. Detailed Microsoft Entra logging enhances auditability and simplifies compliance reporting. Integrate Security Controls: Strengthen RBAC by integrating with Microsoft Entra Conditional Access, Defender for Cloud, and Azure Policy. For more on the Azure RBAC features specific to AKV, see the Azure Key Vault RBAC Guide. For a comprehensive security checklist, see Secure your Azure Key Vault. Migrating from Access Policies to RBAC To transition your Key Vault from legacy access policies to RBAC, follow these steps: Prepare: Confirm you have the necessary administrative permissions and gather an inventory of applications and users accessing the vault. Conduct inventory: Document all current access policies, including the specific permissions granted to each identity. Assign RBAC Roles: Map each identity to an appropriate RBAC role (e.g., Reader, Contributor, Administrator) based on the principle of least privilege. Enable RBAC: Switch the Key Vault to the RBAC authorization model. Validate: Test all application and user access paths to ensure nothing is inadvertently broken. Monitor: Implement monitoring and alerting to detect and respond to access issues or misconfigurations. For detailed, step-by-step instructions—including examples in CLI and PowerShell—see Migrate from access policies to RBAC. Conclusion Now is the time to modernize access control strategies. Adopting Role-Based Access Control (RBAC) not only eliminates configuration drift and overly broad permissions but also enhances operational efficiency and strengthens your defense against evolving threat landscapes. Transitioning to RBAC is a proactive step toward building a resilient and future-ready security framework for your Azure environment. Overexposed Azure Key Vaults aren’t just isolated risks — they act as breach multipliers. Treat them as Tier-0 assets, on par with domain controllers and enterprise credential stores. Protecting them requires the same level of rigor and strategic prioritization. By enforcing network segmentation, applying least-privilege access through RBAC, and integrating continuous monitoring, organizations can dramatically reduce the blast radius of a potential compromise and ensure stronger containment in the face of advanced threats.

Security compliance across multicloud environments is challenging due to the diversity and complexity of platforms. Each cloud provider—whether AWS, Azure, Google Cloud, or others—has its own security protocols, configurations, and compliance requirements. This variation can lead to discrepancies and gaps in security posture, as what works in one cloud environment may not be applied seamlessly in another. Managing multiple compliance frameworks simultaneously adds complexity, especially when each provider has different methods for meeting these standards. Without unified compliance visibility, security teams are forced to monitor each cloud platform independently, which is time-consuming and prone to human error. This fragmentation can lead to missed compliance requirements, especially when resources are limited or when team members are unfamiliar with specific cloud platforms. As a result, organizations face increased risks of data breaches, fines, and reputational damage if they fail to meet regulatory requirements consistently across all platforms. A streamlined approach ultimately strengthens the organization’s security posture and simplifies the path to achieving and maintaining compliance across complex, multi-cloud landscapes. Microsoft Defender for Cloud aids security teams in meeting various regulations and industry standards through our Regulatory Compliance dashboard. Each standard has multiple compliance controls, which are groups of related security recommendations. Defender for Cloud constantly evaluates the environment against these controls, indicating whether resources are compliant or non-compliant. To help security teams streamline with compliance teams, Defender for Cloud regulatory compliance signals can be integrated into Microsoft Purview Compliance Manager. Today, we’re excited to share enhanced and expanded support of over 30 regulatory compliance frameworks in Defender for Cloud, across Azure, AWS, and GCP.

Cloud security has become increasingly complicated. As organizations spread their computer systems across different cloud providers like Azure, AWS, and Google Cloud Platform, keeping everything secure has gotten much harder. Security teams are now dealing with a much more complex challenge than ever before. The core issue is how spread out and interconnected these systems have become. A single small mistake can create security risks that spread across multiple networks, turning what might look like a minor problem into a potential major security threat. The traditional ways of checking security issues manually just don't work anymore - there are simply too many potential risks to track by hand. Microsoft Defender for Cloud’s Cloud Security Posture Management (CSPM) solution is purpose-built for this challenge. It continuously assesses your cloud environments, surfaces vulnerabilities, and prioritizes them based on context-aware factors such as business impact, exposure, and resource configuration. By proactively identifying and ranking security issues, Defender CSPM enables organizations to focus on limited resources where they matter most, reducing the risk of breaches and strengthening their overall security posture. This article will dive into why proactive risk identification and prioritization are essential in multicloud environments. We will also provide a detailed operational framework, covering continuous vulnerability scanning, contextual risk assessment, automated remediation, and SIEM integration, to help you integrate these capabilities into your daily workflows. The result: a more mature, efficient, and forward-looking approach to cloud security. The Strategic Importance of Proactive Risk Identification Managing Complexity Across Clouds: Multicloud infrastructures combine diverse platforms, services, and configurations, increasing the likelihood of misconfigurations and overlooked vulnerabilities. Without a smart, forward-looking approach, security teams end up constantly chasing problems instead of preventing them. Reducing Exposure to Emerging Vulnerabilities: New vulnerabilities surface regularly, whether tied to platforms, operating systems, or third-party libraries. Proactive scanning and continuous assessments help close the window of exposure, ensuring that your team can address issues before attackers have the chance to exploit them. Preventing Security Debt: Unchecked vulnerabilities accumulate over time, creating “security debt” that becomes increasingly difficult, and expensive to resolve. Proactive identification ensures that issues are tackled as they arise, maintaining a manageable, prioritized backlog of remediation tasks. Optimizing Security Resources: With limited budgets and personnel, it’s crucial to channel resources toward the most impactful risks. By identifying and prioritizing vulnerabilities, your organization can respond efficiently, ensuring critical issues are resolved promptly while lower-priority tasks are handled later. How Defender CSPM Enhances Proactive Risk Management Continuous Security Assessments: Defender CSPM continuously scans your environment for misconfigurations, policy violations, and vulnerabilities across Azure, AWS, and GCP. Rather than relying on sporadic audits, you gain real-time visibility into your security posture, ensuring that newly introduced risks are identified immediately. Contextualized Risk Prioritization: Defender CSPM goes beyond surface-level scoring. Its context-aware analysis evaluates vulnerabilities based on how essential a resource is, its network exposure, and its overall configuration. This ensures that high-impact vulnerabilities affecting critical business systems or publicly exposed endpoints rise to the top of your remediation list. To dive into how Defender for Cloud estimates the security risk level for resources assessed, refer to this blog article Contextual Risk Estimation for Effective Prioritization. Attack Path Visualization: By mapping out potential attack paths, Defender CSPM reveals how minor issues may form part of a larger exploit chain. Understanding these scenarios helps your team prioritize critical breakpoints, closing off avenues of attack before they can be leveraged. To learn how to perform this task in Defender for Cloud, read about Attack Path Analysis. Automated Remediation Guidance: Defender CSPM’s risk scores and contextual insights pave the way for automated remediation playbooks. These playbooks allow you to standardize and accelerate responses, reducing the time vulnerabilities that remain open and vulnerable to exploitation.

Operationalizing Proactive Risk Identification: A Step-by-Step Framework Achieving proactive risk management in a multicloud world requires more than theoretical understanding - it calls for clear workflows, assigned responsibilities, and the right technology integrations. Below is a blueprint for operationalizing proactive risk identification and prioritization with Defender CSPM. Step 1: Implement Continuous Vulnerability Scanning Objectives: Continuously monitor all cloud environments for new vulnerabilities. Establish a baseline security posture through automated scanning. Operational Workflow: Environment Readiness: Conduct an audit of all cloud platforms and ensure each resource is properly tagged and configured for Defender CSPM. Assign a Cloud Security Architect to work with platform teams to guarantee that every environment - development, testing, and production - is included in continuous scans. Automated Scans Across Clouds: Enable Defender CSPM to run automated, continuous scans across your entire cloud environment. Use tools like Azure Policies, Infrastructure as Code (IaC) templates, and APIs to build security directly into your deployment process. This means every new cloud environment and resource get checked for potential risks the moment it's created, not as an afterthought. Role-Based Dashboards and Alerts: Tailor dashboards so that Cloud Operations, Security Analysts, and Security Engineers each see relevant data. Set up Role-Based alerts and notifications that signal when critical issues are detected. Security Orchestration: Integrate workflow automation and Logic Apps to trigger alerts, assign remediation tasks, or even initiate corrective measures the moment high-risk vulnerabilities surface. Step 2: Assess Business Impact and Exploitability Objectives: Prioritize vulnerabilities based on their actual risk to the business. Understand which systems, applications, and data are mission critical. Operational Workflow: Define Critical Assets: Collaborate with business stakeholders to identify mission-critical resources and label them accordingly in Defender CSPM. A Resource Criticality Framework ensures that vulnerabilities in these assets receive elevated scrutiny. Regular Risk Review Workshops: Host bi-weekly sessions with security, IT operations, and business leads to review critical vulnerabilities. Discuss potential exploitation scenarios and validate whether the assigned priority aligns with your organization’s risk tolerance. Integrate Threat Intelligence: Leverage Microsoft Threat Intelligence and SIEM (e.g., Microsoft Sentinel) integrations to gauge exploit likelihood. By correlating vulnerabilities with known threats, you refine prioritization even further. Step 3: Establish Automated Remediation Playbooks Objectives: Accelerate response times to high-priority vulnerabilities. Reduce manual effort and human error in remediation tasks. Operational Workflow: Design Actionable Playbooks: Identify common vulnerabilities, like open ports or unencrypted storage, and create predefined remediation actions. Work closely with DevOps and Cloud Security teams to standardize these processes. Real-Time Remediation Triggers: Configure Defender CSPM’s workflow automation so that when a high-priority vulnerability is detected, a remediation playbook automatically runs. This could mean instantly closing an exposed port or applying a missing security policy. Continuous Improvement: Review remediation effectiveness monthly. Adjust playbooks based on feedback, evolving threats, and changes in your cloud configurations, ensuring they remain relevant and effective. Step 4: Integrate with SIEM and XDR for Comprehensive Risk Management Objectives: Achieve centralized visibility and incident correlation. Enhance detection and response capabilities by combining CSPM insights with real-time threat data. Streamline end-to-end threat management by leveraging CSPM findings into Microsoft Extended Detection and Response (XDR) workflows. Operational Workflow: SIEM Integration: Connect Defender CSPM to your SIEM (e.g., Microsoft Sentinel) for centralized monitoring. Assign a Security Orchestration Team to configure continuous data export and ensure seamless integration. Correlate Vulnerabilities with Threats: Develop custom SIEM rules to link CSPM-detected vulnerabilities with active threat events. This correlation helps you identify which vulnerabilities are being targeted and prioritize them accordingly. Automated Incident Response: Combine SIEM-powered analytics with automated remediation playbooks. If an active attack focuses on a known vulnerability, your SIEM can trigger an incident response workflow—isolating resources or patching systems—in real-time. XDR for Threat Detection and Response: Leverage MDC Integration with Microsoft XDR to enhance the end-to-end detection, investigation, and response lifecycle. Read more about the integration here – Microsoft XDR and Microsoft Defender for Cloud, and watch this YouTube video. Measuring Success: Key Performance Indicators Assessing the impact of your proactive risk identification strategy involves tracking KPIs that reflect improved security maturity: Incident Response Time & MTTR: Shorter response times and mean times to repair indicate improved readiness and efficiency. Reduced Exposure: Fewer publicly exposed vulnerabilities mean attackers have fewer entry points. Remediation Rate: A higher remediation rate signals that your operational processes effectively address identified issues. Compliance Metrics: Improved compliance audit outcomes show that security initiatives and controls are meeting regulatory standards. Conclusion Proactive risk identification and prioritization are the bedrock of a robust, scalable, and future-proof cloud security strategy. By combining Defender CSPM’s continuous scanning, contextual risk scoring, and automated remediation capabilities with a structured operational framework, your organization can swiftly tackle critical vulnerabilities, optimize resource allocation, and strengthen its overall security posture.

Elevate Your Container Posture: From Agentless Discovery to Risk Prioritization
As Kubernetes (K8s) continue to power modern containerized applications, the complexity of managing and securing these environments grows exponentially. The challenges in monitoring K8s environments stem not only from their dynamic nature but also from their unique structure—each K8s cluster operates as its own ecosystem, complete with its own control plane for authorization, networking, and resource management. This makes it fundamentally different from traditional cloud environments, where security practitioners often have established expertise and tools for managing the cloud control plane. The specialized nature of Kubernetes (K8s) environments limits the visibility and control available to many security teams, resulting in blind spots that increase the risk of misconfigurations, compliance gaps, and potential attack paths gaining comprehensive visibility into the posture state of K8s workloads is essential for addressing these gaps and ensuring a secure, resilient infrastructure. Key benefits By further expanding agentless container posture approach, Defender for Cloud delivers the following key benefits: Enhanced risk management: improved prioritization through additional security insights, networking information, K8s RBAC, and image evaluation status, ensuring more critical issues can addressed first. Proactive security posture: gain comprehensive insights and prevent lateral movement within Kubernetes clusters, helping to identify and mitigate threats before they cause harm. Comprehensive compliance and governance: achieve full transparency into software usage and Kubernetes RBAC configurations to meet compliance requirements and adhere to industry standards. Release features overview: Enhanced K8s workload modeling To ensure customers can better focus on security findings, and avoid reviewing stale information, Defender for Cloud now models K8s workloads in the security graph based on their configuration (K8s specification) rather than runtime assets. This improvement avoids refresh-rate discrepancies, providing a more accurate and streamlined view of your K8s workloads, with single security findings for all identical containers within the same workload. New Security Insights for Containers and Pods Security teams that use the security explorer to proactively identify security risks in their multicloud environments, now get even better visibility with additional security insights for containers and pods, including privileged containers, sensitive mounts, and more. For example, security practitioners can use the security explorer to find all containers vulnerable to remote code execution, which are also exposed to the internet and uses sensitive host mounts, to eliminate the misconfigurations and vulnerabilities before a potential attacker abuse them to attack the container remotely and break-out into the host through the sensitive host mount. Extended K8s Networking Information To enable customers to query the security graph based on additional characters of K8s networking and better understand exposure details for K8s workloads, Defender for Cloud now offers extended data collection for both K8s ingresses and services. This feature also includes new properties such as service port and service selectors. The following figure shows all new networking criteria that customers can now use to query for K8s networking configuration: The following figure show detailed exposure information on a K8s workload exposed to the internet: Enhanced image discovery Customers can now gain complete visibility to all images used in customer environments using the security explorer, including images from all supported registries, and any image running in K8s, regardless of whether the image is scanned for vulnerabilities, with extended information per image. Here are a few examples for important use cases that customers can detect and respond to action on through a single query in the security explorer: Detect usage of images from unmonitored registries: Figure 4: images deployed directly from an unscanned docker registry Check the presence of specific image in the environment Figure 5: search for an image with a specific digest Trace all images not evaluated for vulnerabilities Figure 6: all images not assessed for vulnerabilities K8s RBAC in the security graph The addition of K8s RBAC into the security graph serves two main purposes: Security practitioners gain easy visibility into K8s service accounts, their permissions, and their bindings with K8s workloads, without prior expertise, and hunt for service accounts that do not meet security best practices. In the following example, a service account that has full cluster permissions: Figure 7: example of service account cluster admin permissions on cluster level The security graph contextual analysis uses the K8s RBAC to identify lateral movement internally within K8s, from K8s to other cloud resources and from the cloud to K8s. The following example shows an attack path starting from a container exposed to the internet with a vulnerability that can be remotely exploited. It also has access to a managed identity allowing the attacker to move all the way to a critical storage account: Figure 8: attack path from a vulnerable exposed container to a critical storage account Comprehensive Software Inventory for Containers A detailed software inventory is now available for all container images and containers scanned for vulnerabilities, serving security practitioners and compliance teams in many ways: Full visibility to all software packages used in container images and containers: Figure 9: Full software list for images and containers Query specific software usage across all environments, making it easier to identify risks or ensure compliance. A common example of this use case includes a vulnerable software version with a zero-day vulnerability. For example, following the OpenSSL zero-day vulnerability publication, a security admin can use the following queries to find all instances of container images within the organization using OpenSSL version 3.0, even before a CVE was published: Figure 10: search for a specific vulnerable open ssl version Critical Asset Protection for K8s Critical asset protection has been enhanced to cover additional container use cases: Defender for cloud customers can now define rules to mark workloads as critical based on their namespace and K8s labels. The following figure shows how customers can define rules that would automatically tag critical workloads based on their K8s labels: Figure 11: customer defined rules for asset criticality based on K8s labels Predefined rules allow K8s clusters to be flagged as critical, ensuring prioritized focus during risk assessments. Example for one of the predefined rules that automatically tags K8s clusters as critical: Figure 12: Example for predefined K8s cluster criticality rules As with other asset protection features in Defender for Cloud, these updates seamlessly integrate into the risk prioritization, attack path analysis, and security explorer workflows. The following example shows a critical attack path where the attack target is critical K8s cluster: Figure 13: Critical attack path where the target is a critical K8s cluster K8s CIS benchmark Customers that would like to audit their K8s clusters for regulatory compliance using K8s CIS or enforce security controls that are part of the K8s CIS standard, now benefit from updated K8s CIS standards with broader security controls, with K8s CIS 1.5.0 for AKS, and EKS and K8s CIS 1.6.0 for GKE. To start using the new standards and controls, enable the desired K8s CIS standard through regulatory compliance dashboard, or via security policies: Figure 14: Enabling K8s CIS 1.6.0 for GKE Compliance status can then be monitored via the regulatory compliance dashboard for the relevant K8s CIS standard: Figure 15: Viewing K8s CIS 1.5.0 compliance status Get Started Today To start leveraging these new features in Microsoft Defender for Cloud, ensure either Defender for Container or Defender CSPM is enabled in your cloud environments.

Generative AI applications have rapidly transformed industries, from marketing and content creation to personalized customer experiences. These applications, powered by sophisticated models, bring unprecedented capabilities—but also unique security challenges. As developers build generative AI systems, they increasingly rely on containers and APIs to streamline deployment, scale effectively, and ensure consistent performance. However, the very tools that facilitate agile development also introduce new security risks. Containers, essential for packaging AI models and their dependencies, are susceptible to misconfigurations and can expose entire systems to attacks if not properly secured. APIs, which allow seamless integration of AI functionalities into various platforms, can be compromised if they lack robust access controls or encryption. As generative AI becomes more integrated into critical business processes, security admins are challenged with continuously hardening the security posture of the foundation for AI application. Ensuring core workloads, like containers and APIs, are protected is vital to safeguard sensitive data of any application. And when introducing generative AI, remediating vulnerabilities and misconfigurations efficiently, ensures a strong security posture to maintain the integrity of AI models and trust in their outputs. New cloud security posture innovations in Microsoft Defender Cloud Security Posture Management (CSPM) help security teams modernize how they proactively protect their cloud-native applications in a unified experience from code to runtime. API security posture management is now natively available in Defender CSPM We're excited to announce that API security posture management is now natively integrated into Defender CSPM and available in public preview at no additional cost. This integration provides comprehensive visibility, proactive API risk analysis, and security best practice recommendations for Azure API Management APIs. Security teams can use these insights to identify unauthenticated, inactive, dormant, or externally exposed APIs, along and receive risk-based security recommendations to prioritize and implement API security best practices. Additionally, security teams can now assess their API exposure risks within the context of their overall application by mapping APIs to their backend compute hosts and visualizing the topology powered by cloud security explorer. This mapping now enables end-to-end API-led attack path analysis, helping security teams proactively identify and triage lateral movement and data exfiltration risks. We’ve also enhanced API security posture capabilities by expanding sensitive data discovery beyond request and response payloads to now include API URLs, path, query parameters, and the sources of data exposure in APIs. This allows security teams to track and mitigate sensitive data exposure across cloud applications efficiently. In addition, the new support for API revisions enables automatic onboarding of all APIs, including tagged revisions, security insights assessments, and multi-regional gateway support for Azure API Management premium customers. Enhanced container security posture across the development lifecycle While containers offer flexibility and ease of deployment, they also introduce unique security challenges that need proactive management at every stage to prevent vulnerabilities from becoming exploited threats. That’s why we’re excited to share new container security and compliance posture capabilities in Defender CSPM, expanding current risk visibility across the development lifecycle: It's crucial to validate the security of container images during the build phase and block the build if vulnerabilities are found, helping security teams prevent issues at the source. To support this, we’re thrilled to share container image vulnerability scanning for any CI/CD pipeline is now in public preview. The expanded capability offers a command-line interface (CLI) tool that allows seamless CI/CD integration and enables users to perform container image vulnerability scanning during the build stage, providing visibility into vulnerabilities at build. After integrating their CI/CD pipelines, organizations can use the cloud security explorer to view container images pushed by their pipelines. Once the container image is built, scanned for vulnerabilities, it is pushed to a container registry until ready to be deployed to runtime environments. Organizations rely on cloud and third-party registries to pull container images, making these registries potential gateways for vulnerabilities to enter their environment. To minimize this, container image vulnerability scanning is now available for third-party private registries, starting with Docker Hub and JFrog Artifactory. The scan results are immediately available to both the security teams and developers to expedite patches or image updates before the container image is pushed to production. In addition to container security posture capabilities, security admins can also strengthen the compliance posture of Kubernetes across clouds. Now in public preview, security teams can leverage multicloud regulatory compliance assessments with support for CIS Kubernetes Benchmarks for Amazon Elastic Kubernetes Service (EKS), Azure Kubernetes Service, and Google Kubernetes Engine (GKE). AI security posture management (AI-SPM) is now generally available Discover vulnerability and misconfiguration of generative AI apps using Azure OpenAI Service, Azure Machine Learning, and Amazon Bedrock to reduce risks associated with AI-related artifacts, components, and connectors built into the apps and provide recommended actions to proactively improve security posture with Defender CSPM. New enhancements in GA include: Expanded support of Amazon Bedrock provides deeper discovery of AWS AI technologies, new recommendations, and attack paths. Additional support for AWS such as Amazon OpenSearch (service domains and service collections), Amazon Bedrock Agents, and Amazon Bedrock Knowledge Bases. New AI grounding data insights provides resource context to its use as a grounding source within an AI application. Grounding is the invisible line between organizational data and AI applications. Ensuring the right data is used – and correctly configured in the application – for grounding can reduce hallucinations, prevent sensitive data loss, and reduce the risk of grounding data poisoning and malicious outputs. Customers can use the cloud security explorer to query multicloud data used for AI grounding. New ‘used for AI grounding’ risk factor in recommendations and attack paths can also help security teams prioritize risks to datastores. Thousands of organizations are already reaping the benefits of AI-SPM in Defender CSPM, like Mia Labs, an innovative startup that is securely delivering customer service through their AI assistant with the help of Defender for Cloud. “Defender for Cloud shows us how to design our processes with optimal security and monitor where jailbreak attempts may have originated.” Marwan Kodeih, Chief Product Officer, Mia Labs, Inc. New innovations to find and fix issues in code with new DevOps security innovations Addressing risks at runtime is only part of the picture. Remediating risks in the Continuous Integration/Continuous Deployment (CI/CD) pipeline is equally critical, as vulnerabilities introduced in development can persist into production, where they become much harder—and costlier—to fix. Insecure DevOps practices, like using untrusted images or failing to scan for vulnerabilities, can inadvertently introduce risks before deployment even begins. New innovations include: Agentless code scanning, now in public preview, empowers security teams to quickly gain visibility into their Azure DevOps repositories and initiate an agentless scan of their code immediately after onboarding to Defender CSPM. The results are provided as recommendations for exposed Infrastructure-as-Code misconfigurations and code vulnerabilities. End-to-end secrets mapping, now in public preview, helps customers understand how a leaked credential in code impacts deployed resources in runtime. It provides deeper risk insights by tracing exposed secrets back to code repositories where it originated, with both secret validation and mapping to accessible resources. Defender CSPM now highlights which secrets could cause the most damage to systems and data if compromised. Additional CSPM enhancements [General Availability] Critical asset protection: Enables security admins to prioritize remediation efforts with the ability to identify their ‘crown jewels’ by defining critical asset rules in Microsoft Security Exposure Management and applying them to their cloud workloads in Defender for Cloud. As a result, the risk levels of recommendations and attack paths consider the resource criticality tags, streamlining prioritization above other un-tagged resources. In addition to the General Availability release, we are also extending support for tagging Kubernetes and non-human identity resources. [Public Preview] Simplified API security testing integration: Integrating API security testing results into Defender for Cloud is now easier than ever. Security teams can now seamlessly integrate results from supported API security testing providers into Defender for Cloud without needing a GitHub Advanced Security license.
