We have our devices onboarded to Defender for Endpoint, and want to program Firewall Policy and Firewall Rules Policy using Defender Onboarding. We know that we can onboard devices to Intune and use Intune MDM to program rules. But, we don't want a full blown MDM setup or license for just firewall programming. Is there a deployment scenario where we can do firewall programming just using defender machines. Any help is really appreciated.Solved258Views0likes1CommentUnable to add Endpoints and Vulnerability management in XDR Permissions

I am getting incidents for DFE, and this is being sent to my SOAR platform for analysis, but when I pivot back using client-sync, I cannot see DFE incidents. I have gone into Settings > XDR > Workload settings, and can only see the below There does not appear to be the option to grant the roles I have provided for my SOAR user the ability to see Endpoint and Vulnerability management. Really scratching my head here. Help?250Views0likes3CommentsHow to Connect MS Secure Scores to Power Query?
The Microsoft 365 Defender Portal (https://security.microsoft.com/) has a 'Secure Score' page, which contains the following: An overall secure score which is then broken down by Identity, Data, Device, and Application secure scores. I would like to be able to pull these four scores into a Power BI report; however, I have had some difficulty in putting together a solution. This data seems like it could be found in the Microsoft Graph API, but https://learn.microsoft.com/en-us/power-query/connecting-to-graph. I've tried other Defender APIs, but they all seem either outdated or out of scope for what I'm trying to pull. Can anyone advise? Thanks for reading.2.7KViews0likes2CommentsAutomatic attack disruption: Enhanced containment for critical assets and shadow IT
Staying ahead of attackers is tough, as they constantly evolve and use advanced techniques like AI to exploit vulnerabilities. Protecting high-value assets is even harder, as these are prime targets. Security teams must constantly adapt to outpace attackers, balancing proactive measures with the need for speed and innovation. This is why Microsoft Defender XDR developed automatic attack disruption, a built-in self-defense capability that contains in-progress attacks to prevent further lateral movement & damage to an organization. We’re thrilled to introduce new, extended capabilities in automatic attack disruption, designed to further stop attackers and restrict them from moving laterally across the network by leveraging compromised devices. Specifically, within Microsoft Defender for Endpoint which disrupt ransomware on its own. With this expansion, we now offer: Granular containment of critical assets – Helping ensure essential infrastructure remains operational while blocking attacker activity. Containment of IP addresses linked to undiscovered devices – Helping to prevent attackers from exploiting shadow IT and unmanaged endpoints. Granular Containment of Critical Assets Critical assets—such as Domain Controllers, DNS, and DHCP servers—are prime targets for adversaries. These systems serve as strategic footholds for attackers to establish persistence, escalate privileges, and compromise further resources. However, containing these devices has traditionally been challenging, as full isolation could disrupt business operations. With this new capability, Defender for Endpoint applies intelligent, device role-based, granular containment to limit only specific network functionalities and interfaces used for malicious activity, while keeping essential functions running. This means: Attackers lose their ability to move laterally and escalate their attack. Key network functions are preserved, ensuring business continuity. Compromised critical assets remain operational while being protected. Containing IP addresses of undiscovered devices Shadow IT and unmanaged devices present a hidden security risk. Often unmonitored, these devices become easy targets for attackers to exploit for lateral movement. With the new IP address containment capability, Defender for Endpoint can now identify and incriminate malicious IP addresses linked to unmanaged or undiscovered devices and automatically contain those IPs, preventing attackers from getting their foot in the door through vulnerable, unmanaged devices before spreading to other non-compromised devices. Configuring IP containment Excluding assets from automatic attack disruption is not recommended as it can reduce the effectiveness of protecting your environment from sophisticated, high-impact attacks. If there is still a need to exclude an IP subnet or multiple IP addresses, this can be done within the Microsoft Defender XDR portal as follows: Under Automated responses, select Devices. In the IPs tab, select Exclude IP to exclude an IP address. In the flyout pane, enter the IP address/IP range/IP subnet you want to exclude. You can add multiple IP addresses and IP subnets by separating them with a comma. For full configuration options see the Defender XDR documentation. While security is undeniably challenging, security analysts should feel empowered by their tools to effectively combat against attacks. With continuous innovation and the ability to adapt to the latest threats, they can stay resilient and confident in their ability to protect valuable assets. The ever-evolving landscape of cybersecurity is demanding, but with the right resources, analysts are well-equipped to tackle it head-on.

I am trying to create some custom asset management rules based on filters like logged on username, user criticality, and user groups. No matter what I try no assets show up. Even if I use the format azuread\<username>, no assets are returned by the filter. Are these filters incompatible with Entra ID? Do they only work with on-premise AD?169Views0likes4CommentsWhat’s new in Microsoft Defender XDR at Secure 2025
Protecting your organization against cybersecurity threats is more challenging than ever before. As part of our 2025 Microsoft Secure cybersecurity conference announcements, we’re sharing new product features that spotlight our AI-first, end-to-end security innovations designed to help - including autonomous AI agents in the Security Operations Center (SOC), as well as automatic detection and response capabilities. We also share information on how you can expand your protection by bringing data security and collaboration tools closer to the SOC. Read on to learn more about how these capabilities can help your organization stay ahead of today’s advanced threat actors. Expanding AI-Driven Capabilities for Smarter SOC Operations Introducing Microsoft Security Copilot’s Phishing Triage Agent Today, we are excited to introduce Security Copilot agents, a major step in bringing AI-driven automation to Microsoft Security solutions. As part of this, we’re unveiling our newest innovation in Microsoft Defender: the Phishing Triage Agent. Acting as a force multiplier for SOC analysts, it streamlines the triage of user-submitted phishing incidents by autonomously identifying and resolving false positives, typically cleaning out over 95% of submissions. This allows teams to focus on the remaining incidents – those that pose the most critical threats. Phishing submissions are among the highest-volume alerts that security teams handle daily, and our data shows that at least 9 in 10 reported emails turn out to be harmless bulk mail or spam. As a result, security teams must sift through hundreds of these incidents weekly, often spending up to 30 minutes per case determining whether it represents a real threat. This manual triage effort not only adds operational strain but also delays the response to actual phishing attacks, potentially impacting protection levels. The Phishing Triage Agent transforms this process by leveraging advanced LLM-driven analysis to conduct sophisticated assessments –such as examining the semantic content of emails– to autonomously determine whether an incident is a genuine phishing attempt or a false alarm. By intelligently cutting through the noise, the agent alleviates the burden on SOC teams, allowing them to focus on high-priority threats. Figure 1. A phishing incident triaged by the Security Copilot Phishing Triage Agent To help analysts gain trust in its decision-making, the agent provides natural language explanations for its classifications, along with a visual representation of its reasoning process. This transparency enables security teams to understand why an incident was classified in a certain way, making it easier to validate verdicts. Analysts can also provide feedback in plain language, allowing the agent to learn from these interactions, refine its accuracy, and adapt to the organization’s unique threat landscape. Over time, this continuous feedback loop fine-tunes the agent’s behavior, aligning it more closely with organizational nuances and reducing the need for manual verification. The Security Copilot Phishing Triage Agent is designed to transform SOC operations with autonomous, AI-driven capabilities. As phishing threats grow increasingly sophisticated and SOC analysts face mounting demands, this agent alleviates the burden of repetitive tasks, allowing teams to shift their focus to proactive security measures that strengthen the organization’s overall defense. Security Copilot Enriched Incident Summaries and Suggested Prompts Security Copilot Incident Summaries in Microsoft Defender now feature key enrichments, including related threat intelligence and asset risk –enhancements driven by customer feedback. Additionally, we are introducing suggested prompts following incident summaries, giving analysts quick access to common follow-up questions for deeper context on devices, users, threat intelligence, and more. This marks a step towards a more interactive experience, moving beyond predefined inputs to a more dynamic, conversational workflow. Read more about Microsoft Security Copilot agent announcements here. New protection across Microsoft Defender XDR workloads To strengthen core protection across Microsoft Defender XDR workloads, we're introducing new capabilities while building upon existing integrations for enhanced protection. This ensures a more comprehensive and seamless defense against evolving threats. Introducing collaboration security for Microsoft Teams Email remains a prevalent entry point for attackers. But the fast adoption of collaboration tools like Microsoft Teams has opened new attack surfaces for cybercriminals. Our advancements within Defender for Office 365 allow organizations to continue to protect users in Microsoft Teams against phishing and other emerging cyberthreats with inline protection against malicious URLs, safe attachments, brand impersonation protection, and more. And to ensure seamless investigation and response at the incident level, everything is centralized across our SOC workflows in the unified security operations platform. Read the announcement here. Introducing Microsoft Purview Data Security Investigations for the SOC Understanding the extent of the data that has been impacted to better prioritize incidents has been a challenge for security teams. As data remains the main target for attackers it’s critical to dismantle silos between security and data security teams to enhance response times. At Microsoft, we’ve made significant investments in bringing SOC and data security teams closer together by integrating Microsoft Defender XDR and Microsoft Purview. We are continuing to build upon the rich set of capabilities and today, we are excited to announce that Microsoft Purview Data Security Investigations (DSI) can be initiated from the incident graph in Defender XDR. Ensuring robust data security within the SOC has always been important, as it helps protect sensitive information from breaches and unauthorized access. Data Security Investigations significantly accelerates the process of analyzing incident related data such as emails, files, and messages. With AI-powered deep content analysis, DSI reveals the key security and sensitive data risks. This integration allows analysts to further analyze the data involved in the incident, learn which data is at risk of compromise, and take action to respond and mitigate the incident faster, to keep the organization’s data protected. Read the announcement here. Figure 2. An incident that shows the ability to launch a data security investigation. OAuth app insights are now available in Exposure Management In recent years, we’ve witnessed a substantial surge in attackers exploiting OAuth applications to gain access to critical data in business applications like Microsoft Teams, SharePoint, and Outlook. To address this threat, Microsoft Defender for Cloud Apps is now integrating OAuth apps and their connections into Microsoft Security Exposure Management, enhancing both attack path and attack surface map experiences. Additionally, we are introducing a unified application inventory to consolidate all app interactions into a single location. This will address the following use cases: Visualize and remediate attack paths that attackers could potentially exploit using high-privilege OAuth apps to access M365 SaaS applications or sensitive Azure resources. Investigate OAuth applications and their connections to the broader ecosystem in Attack Surface Map and Advanced Hunting. Explore OAuth application characteristics and actionable insights to reduce risk from our new unified application inventory. Figure 3. An attack path infused with OAuth app insights Read the latest announcement here AI & TI are critical for effective detection & response To effectively combat emerging threats, AI has become critical in enabling faster detection and response. By combining this with the latest threat analytics, security teams can quickly pinpoint emerging risks and respond in real-time, providing organizations with proactive protection against sophisticated attacks. Disrupt more attacks with automatic attack disruption In this era of multi-stage, multi-domain attacks, the SOC need solutions that enable both speed and scale when responding to threats. That’s where automatic attack disruption comes in—a self-defense capability that dynamically pivots to anticipate and block an attacker’s next move using multi-domain signals, the latest TI, and AI models. We’ve made significant advancements in attack disruption, such as threat intelligence-based disruption announced at Ignite, expansion to OAuth apps, and more. Today, we are thrilled to share our next innovation in attack disruption—the ability to disrupt more attacks through a self-learning architecture that enables much earlier and much broader disruption. At its core, this technology monitors a vast array of signals, ranging from raw telemetry data to alerts and incidents across Extended Detection and Response (XDR) and Security Information and Event Management (SIEM) systems. This extensive range of data sources provides an unparalleled view of your security environment, helping to ensure potential threats do not go unnoticed. What sets this innovation apart is its ability learn from historical events and previously seen attack types to identify and disrupt new attacks. By recognizing similar patterns across data and stitching them together into a contextual sequence, it processes information through machine learning models and enables disruption to stop the attack much earlier in the attack sequence, stopping significantly more attacks in volume and variety. Comprehensive Threat Analytics are now available across all Threat Intelligence reports Organizations can now leverage the full suite of Threat Analytics features (related incidents, impacted assets, endpoints exposure, recommended actions) on all Microsoft Threat Intelligence reports. Previously only available for a limited set of threats, these features are now available for all threats Microsoft has published in Microsoft Defender Threat Intelligence (MDTI), offering comprehensive insights and actionable intelligence to help you ensure your security measures are robust and responsive. Some of these key features include: IOCs with historical hunting: Access IOCs after expiration to investigate past threats and aid in remediation and proactive hunting. MITRE TTPs: Build detections based on threat techniques, going beyond IOCs to block and alert on specific tactics. Targeted Industries: Filter threats by industry, aligning security efforts with sector-specific challenges.

Hello eveyone, We have configured Defender to detect viruses, and our goal is that if one of our assets downloads or encounters a virus, it is automatically hidden or removed. Based on the documentation regarding the automation levels in Automated Investigation and Remediation capabilities, we have set it to "Full - remediate threats automatically." While this works correctly on Windows devices, we have noticed that on Linux devices, the defender still detect the virus but it was not prevented. I was wondering if anyone has encountered this issue and, if so, how it was resolved? Additionally, as I am new to the Defender platform, I wanted to ask if could this issue potentially be resolved through specific Linux policies or functionalities? Best regards Mathiew66Views1like0Comments
