Defender console - Disabled Connected to a custom indicator & Connected to a unsanctionned
Updated - November 2024 I have found a way to disabling these annoying alerts. Look for the solution above. Issue: I want to know how I can disable these two following alerts : Disabled Connected to a custom indicator Connected to an unsanctioned blocked app Those alerts type needs to be enabled or disabled on demand, like the other alerts types. Why's that : Description of the workload : When we block(Unsanctioned) an application through Defender for Cloud apps. It creates automatically the indicators to Defender XDR. When someone for example click or go the URL related to the application, the following alerts will be triggered. When an indicator is automatically created through that, it checks the box to generate alert when the indicator is triggered. We would like to automatically uncheck the box or disable to alerts describing. Possible to disable the custom alert in setting ? No. Why ? Explanation : You cannot suppress "custom detection". But, they are categorized as "Informational" and you can suppress severity alert type. Solutions : IMPORTANT: Make sure to create a transform rule to not ingest this alerts in Sentinel. That could increased the Resolved incident ingestion and false your SOC optimization reports. The rule is automatically close only the “Informational” alerts with the specified titles. Other Informational alerts with different titles will not be affected. In the Defender XDR setting->Alert tuning->Create this rule: Here's an example: Rule Analysis From the updated rule configuration screenshot, it appears that you’ve set up a filter in the AND condition to only automatically close Informational alerts that do not match specific alert titles (e.g., “Malware was detected in an email message,” “unwanted software,” “malware,” “trojan”). This approach should ensure that the rule closes all Informational alerts except those that contain these specified titles. Here’s a breakdown of how it’s working: 1. Severity Filtering: By setting Alert severity to Informational, only Informational alerts are considered. 2. Title Exclusion: Adding Not equals conditions for each title you want to exclude prevents this rule from affecting those specific alerts. So, any Informational alert with a title that does not match the specified exclusions will be automatically closed. This setup should effectively allow you to close all unwanted Informational alerts while retaining visibility on any malware or security-related Informational alerts that require further review. Regards,Microsoft Azure and Microsoft 365 Security - my defense in depth strategy!
Dear Microsoft Azure and Microsoft 365 security friends, Who is interested in my (small) company? We don't have anything to protect and we don't have any money. Besides, we have a firewall. Furthermore, Mr. Wechsler, you are a bit paranoid with your security thinking. These are the first sentences I always hear when it comes to IT (Cloud) security. But the attacker is also interested in a small company and that is to use their system as a bot. It's not always about money and data. What about the reputation a company has to lose? It takes years to build a good reputation but only one event to damage the reputation. What about the employees, the trust in the company? Do you want to put this at risk as a company, I don't think so! Yes! Extended protection mechanisms always cost extra, I am absolutely aware of that. But I also pay monthly for car insurance and accident and health insurance. I'm grateful every day when I don't need the insurance. That's exactly how it should feel when it comes to IT (cloud) security. Let's start with my IT/Cloud security strategy. I am absolutely aware that this list is not exhaustive. There are so many components to consider, plus every infrastructure/company is always different. I'll try to give you a little help here. We start with Microsoft 365, as a first additional measure, use all policies that start with "Anti-". You can find all the information in the Microsoft 365 Security Center. https://security.microsoft.com/threatpolicy The next step is to use the policies that start with "Safe". You can also find this information in the Microsoft 365 Security Center. Multi factor authentication is a key element to further protect your identities/users. You can set this up per user or with a Conditional Access Policy (my preferred way). Azure Active Directory helps you integrate this protection. https://portal.azure.com If you are subject to a regulatory agency, the Microsoft 365 Compliance Center can help. Here you can set up data loss prevention policies, audits, eDiscovery and much more. https://compliance.microsoft.com/homepage In this day and age of bring your own device and work from home, it's a good idea to include the Endpoint Manager. With it you have the possibility to manage endpoints (Mobile Device Management - MDM) and applications (Mobile Application Management - MAM). https://endpoint.microsoft.com/ Get visibility into your cloud apps using sophisticated analytics to identify and protect against cyberthreats, detect Shadow IT, and control how your data travels. https://portal.cloudappsecurity.com/ The Cloudapp Security Portal provides you with the best possible support. Here you can allow or sanction cloud app, configure anti-ransomware policies, data loss prevention policies and much more. Do you want to know how your Windows Active Directory is doing? Then Microsoft Defender for Identity will help you. With this tool you can transfer the local information to the cloud. With an interface to the CloudApp Security Portal. https://yourtenant.atp.azure.com/timeline No person should always work with elevated rights. Only work with elevated rights when it is really necessary. This is where Azure Privileged Identity Management (PIM) comes in. With this tool you can configure the access as you need it for your needs. https://portal.azure.com With Azure Identity Protection do you have a tool that allows organizations to accomplish three key tasks: 1. Automate the detection and remediation of identity-based risks. 2. Investigate risks using data in the portal. 3. Export risk detection data to third-party utilities for further analysis. https://portal.azure.com Just in time access for administrators, this is also possible for virtual machines with Just in time VM Access. In Microsoft Defender for Cloud you can configure this feature (and much more). Microsoft Sentinel helps you keep track of the health of your organization. A SIEM (Security Information and Event Management) and SOAR (Security Orchestration Automation and Response) tool that should not be missing from your portfolio. The tool offers many connectors (98 at the moment) so that you can connect the most diverse portals to Sentinel. There is still so much to show, I wasn't talking about Role Based Access Control (RBAC) now or Network Security Group (NSG), etc. I know some of you are thinking, hey there is a lot more. I am aware of that. My goal is to give you some positive signals on how you can integrate additional security into your organization. Thank you for taking the time to read this article. Kind regards, Tom Wechsler
Custom data collection in MDE - what is default?
So you just announced the preview of "Custom data collection in Microsoft Defender for Endpoint (Preview)" which lets me ingest custom data to sentinel. Is there also an overview of what is default and what I can add? e.g. we want to examine repeating disconnects from AzureVPN clients (yes, it's most likely just Microsoft's fault, as the app ratings show 'everyone' is having them) How do I know which data I can add to DeviceCustomNetworkEvents which isnt already in DeviceNetworkEvents?
Suggestion: Centralize Microsoft Defender XDR Role Management into Microsoft Entra ID
Microsoft Entra ID has evolved into a strong, centralized identity and access management solution. Likewise, the Defender XDR portal (formerly Microsoft 365 Defender) provides a unified experience for security monitoring, investigation, and response across endpoints, email, identities, and more. These tools are critical to modern SecOps. However, managing access across them is still more complex than it needs to be. Key challenges: Dual RBAC confusion: Defender for Endpoint uses its own RBAC system, separate from Entra ID. This leads to misunderstandings — for example, assigning a user the Security Reader role in Entra ID might not grant expected access in Defender once Defender RBAC is enabled. Hidden roles: Roles like Defender for Endpoint Administrator aren’t visible in the Entra portal, making centralized management harder. Access risks: Enabling Defender RBAC can revoke access for some users unless they’re added manually to MDE role groups — often without clear warning. Admin overhead: Managing permissions separately in Entra and Defender adds duplication, friction, and potential for misconfiguration. Suggestions Let’s build on the strength of Microsoft Entra ID by moving all Defender role assignments into Entra, where identity and access is already managed securely and consistently. Goal: Use only Entra ID roles to manage access to the Defender XDR portal — eliminating the need for custom RBAC roles or portal-based configurations in MDE, MDO, or MDI. Benefits of this change: Centralized, consistent access management across Microsoft security solutions Simplified admin experience with reduced configuration errors Better alignment with Zero Trust and least-privilege principles Clear, discoverable roles for Security and SOC teams Seamless experience during role onboarding/offboarding Suggested new Entra built-in roles for Defender XDR: Defender Endpoint Security Administrator Defender Email Security Administrator Defender Cloud Security Administrator SOC L1 Analyst (read-only) SOC L2 Analyst (response) SOC L3 Analyst (hunting) Defender XDR Administrator / Engineer Vulnerability Analyst Microsoft has done a fantastic job modernizing Entra and unifying security visibility in Defender XDR — and this would be a great next step forward. #MicrosoftEntraID #MicrosoftDefenderXDR #SecurityOperations #IAM #RBAC #CloudSecurity #ZeroTrust #MicrosoftSecurity #SecOps #SOCWhere and how is AI used in Defender XDR?
Hi everyone, i was searching for an overview of where and AI is used in Defender XDR. Do you have a quick oversight of this? That would be great. Also how this data is used for training and decisions. I know it is used in Attack disruption and Copilot for Security ( ;) ) - but i need a complete list. BR Stephan
Support for LDAPS Auth events in XDR IdentityLogonEvents table?
We have a requirement to implement LDAPS auth for an appliance against AD DCs in a legacy environment. The DCs are running Defender for Identity. While testing, using LDAP, I can trace login events in the IdentityLoginEvents table, however when switching to LDAPS, I can't see any related events logged here. Interactive logins using LDAPS are working successfully, as expected, and appear in the Windows event log as EventID:4776 on the DC (but don't appear in the defender portal). It was then that I discovered that this expected behaviour according to the list of supported logon types listed here. https://learn.microsoft.com/en-us/defender-xdr/advanced-hunting-identitylogonevents-table I'm puzzled that XDR would support a cleartext legacy authentication method like LDAP, but would not support the more secure LDAPS protocol. Is there any rationale for this, or intention to introduce support ?SessionID in IdentityLogonEvents?
Hi, The SessionId information is not available in IdentityLogonEvents. The SessionID data can only be found in the XDR table AADSignInEventsBeta. According to the documentation of that table "All sign-in schema information will eventually move to the IdentityLogonEvents table". I cannot find the SessionID in Sentinel anywhere else than in CloudAppEvents. Is this expected? How are we supposed to investigate stolen sessions without the sessionId information in Sentinel?Unable to create an evaluation XDR environment
Following the below article to create and get access to Microsoft Defender XDR, I have procured the necessary licenses and also enabled all the other Defender workloads with the needed unified permission settings. I have also done the necessary configurations in Sentinel as well to get the XDR experience but not able to do so! If anybody has been able to successfully create an evaluation environment or have access to Defender XDR, kindly help me out here! https://learn.microsoft.com/en-us/microsoft-365/security/defender/eval-create-eval-environment?view=o365-worldwideWhat is the best approach to protected Azure Hosted VM?
Hi Community, One of our customer has Azure VM machines hosted platform and there is no on-prem dependency. They would like to understand what are the capabilities of Microsoft Sentinel over M365 Defender while protecting the VMs from threats. Questions: 1. What is recommended for the Azure Windows VM hosted environment? 2. What are the additional values if we recommend M365 Sentinel over M365 Defender? Any pointers would be of great help. Thanks in advance!
