Hi all, I'm string to ingest IOCs from Google Threat Intelligence into Sentinel. I follow the guide at gtidocs.virutotal.com/docs/gti4sentinel-guide API KEY is correct. PS: I'm using standard free public API (created in Viru Total) Managed Identitity has been configured using the correct role. When I run the Logic APP, I received an HTTP error 403 "code": "ForbiddenError", "message": "You are not authorized to perform the requested operation" What's the problem ?? Regards, HA23Views0likes0CommentsIssue when ingesting Defender XDR table in Sentinel
Hello, We are migrating our on-premises SIEM solution to Microsoft Sentinel since we have E5 licences for all our users. The integration between Defender XDR and Sentinel convinced us to make the move. We have a limited budget for Sentinel, and we found out that the Auxiliary/Data Lake feature is sufficient for verbose log sources such as network logs. We would like to retain Defender XDR data for more than 30 days (the default retention period). We implemented the solution described in this blog post: https://jeffreyappel.nl/how-to-store-defender-xdr-data-for-years-in-sentinel-data-lake-without-expensive-ingestion-cost/ However, we are facing an issue with 2 tables: DeviceImageLoadEvents and DeviceFileCertificateInfo. The table forwarded by Defender to Sentinel are empty like this row: We created a support ticket but so far, we haven't received any solution. If anyone has experienced this issue, we would appreciate your feedback. Lucas38Views0likes0CommentsModernize security operations to secure agentic AIβMicrosoft Sentinel at Ignite 2025

Several data connectors downloaded via Content Hub has ARM deployment templates which is default OOB experience. If we need to customize we could however I wanted to ask community how do you go about addressing some of the infrastructure issues where these connectors deploy storage accounts with insecure configurations like infrastructure key requirement, vnet intergration, cmk, front door etc... Storage and Function Apps. It appears default configuration basically provisions all required services to get streams going but posture configuration seems to be dismissing security standards around hardening these services.34Views0likes0CommentsSingle Rule for No logs receiving (Global + Per-device Thresholds)
Hi everyone, I currently maintain one Analytics rule per table to detect when logs stop coming in. Some tables receive data from multiple sources, each with a different expected interval (for example, some sources send every 10 minutes, others every 30 minutes). In other SIEM platforms thereβs usually: A global threshold (e.g., 60 minutes) for all sources. Optional per-device/per-table thresholds that override the global value. Is there a recommended way to implement one global rule that uses a default threshold but allows per-source overrides when a particular device or log table has a different expected frequency? Also, if there are other approaches you use to manage βlogs not receivedβ detection, Iβd love to hear your suggestions as well. This is a sample of my current rule let threshold = 1h; AzureActivity | summarize LastHeartBeat = max(TimeGenerated) | where LastHeartBeat < ago(threshold)36Views1like0CommentsSecurity in Hybrid & Multi-Cloud Environments
Just completed a project on securing hybrid and multi-cloud environments. I explored the challenges of managing security across Azure, AWS, GCP, and on-prem, and how tools like Microsoft Sentinel help bring centralized visibility. Security isnβt one-and-done β itβs a continuous process of monitoring, automation, and enforcing least privilege.2Views0likes0CommentsMulti-trigger Playbooks & Renamed Triggers
Hello Sentinel enthusiasts, In some cases, deploying a playbook with multiple triggers is a much easier solution than having 9 playbooks which do the same thing. In the specific example I'm going for I have developed a playbook which requires the user to change their password within a certain amount of time. We want to have the ability to have three triggers for the playbook - incident, entity and http (for external orchestration platforms) - then we also want to have the option for it to be instant, or within a configurable number of days/hours (1day, 7days). In this situation the native way would be to have 9 playbooks in total - seems like a big amount for a simple action. I attempted to initially develop these playbooks with all three triggers in a base template which is deployed using bicep - success. But what do you know, at first, I could only see the playbook in the automation playbook list saying "Sentinel Action" but I couldn't trigger it from an actual incident or entity. Turns out this was because I had given the trigger a different display name than the default. This specific case seems a bit odd to me because the underlying data is the same, nonetheless - not a huge issue, change the display name to the default and voila. My next surprise was when I realised that the Sentinel UI will only pick up the first trigger to run a playbook. i.e. if I define an entity trigger first then an incident trigger, I cannot see it appear to trigger for an incident and vice versa. So, I set on a mission and was able to create a chromium extension which will modify the resource response - to duplicate a playbook once for every trigger it has (only in the azure portal PWA) and what do I know - everything works perfectly as if it was fully supported. It would be great if these UI bugs could be fixed as they seem pretty trivial and don't seem to require a major change, considering it is solely a frontend bug - especially if I can create an extension which resolves the issue. Obviously, this is not an ideal scenario in production. Garnering some support to have this rectified would be great and it would also be cool to hear people's opinions on this ~Seb61Views0likes0CommentsS1 Data Connector malfunctioning?
I am utilizing the S1 codeless data connector available in the content hub. It would seem that only a few tables are actually populating with data now. Threats and Alerts are no longer being captured. Is anyone else experiencing this? Any work arounds available? Any suggestions would be much appreciated!46Views0likes0CommentsCCP ProofPoint and Zscaler
Hi, I have ProofPoint and Zscaler Data Connector which appear to show as Deprecated. Logs are still flowing via native Azure Function uninterrupted. Per PP - CCP is suggested approach to replace Zscaler - No replacement method but I assume this will also require CCP Has anyone created CCP for these and successfully deployed these solutions?54Views0likes0CommentsRetrieving MailAddress from Entity for Logic App
I'm trying to put together a logic app that will reset a users password and also send them an email notifying them why their password was reset. The logic app triggers off a sentinel incident. The users email address I need to send to is from the Entities properties of the Sentinel incident. How can I extract the users email address? Its in the "MailAddress" property of each Entity. I believe Im going to have to parse it out of the JSON result but need some guidance if that is the case. Appreciate any help.62Views0likes0CommentsLog Analytics Workspace - ThreatIntelIndicators
Morning! I have been working on migrating some of our tenant analytic rules to use the new TI ThreatIntelIndicators table. However, I noticed the following: When querying against the new table, I get these values in a tenant log workspace When I do the same query in another tenant logs workspace, I get this result back If I expand the query to grab last 7 days, I get results back but they are wildly different from what I see from one tenant to another. I can find big and small discrepancies in the logs I see. I still can't find the connector on the connectors page (When I filter them out by data type). I can see the one that is being used for the soon to be decommissioned table. As far as I understand, the connector is not going to be changed per se, just how we access the logs from any given log analytics workspace. I'm expecting to see the same values across my log workspaces since it comes from the same connector, and provided by MS, or is this ingestion of TI logs tenant scope and each one has different settings? I couldn't find something that tells me this in the docs. Or is this part of the rollout problems we are expecting to see? Thanks!135Views0likes0CommentsUnknown Behaviour Involving GroupsService in OfficeActivity
I have spotted a few hundred events with the following KQL query in my environment. This is the result of one of the entries. It looks like a regular legitimate behaviour by Microsoft but I don't seem to find any documentation about it. Can anyone share the insight of it? Thank you!37Views0likes0CommentsAMPLS Restrictions Preventing Outbound API Calls in Logic Apps β Any Workarounds?
Hi everyone, Iβm encountering an issue where Azure Monitor Private Link Scope (AMPLS) restrictions are preventing Azure Logic Apps from making any outbound API calls, even to Microsoft-owned outbound IP addresses. One specific problem is that when running KQL queries inside a Logic App, the Azure Monitor connector fails because it attempts to access Microsoft outbound IPs, which are blocked by AMPLS restrictions. Since this is happening within Logic Apps itself, I donβt have direct control over these outbound calls. Has anyone found a workaround to allow Logic Apps to function correctly while keeping AMPLS in place? Would Private Endpoints, VNET Integration, or any other configuration help resolve this? Any insights or solutions would be greatly appreciated!42Views0likes0CommentsJuniper SRX 340 logs not read by rsyslog
I have configured Juniper SRX 340 Junos logs to be forwarded to a centralized syslog server before reaching Microsoft Sentinel. I can see the Juniper logs on the syslog server while doing a TCPDUMP but, the same logs are not ready by rsyslog. The same syslog server is also receiving the logs from Cisco ASA. The rsyslog is able to read the ASA logs with no issues and further forward them to Sentinel through AMA agent. I don't have any filters applied in rsyslog.conf file and I'm capturing everything (*.*) all syslog facility and severity to a log file but, still the Juniper logs are not recognized by rsyslog. Please help on resolving this issue90Views0likes0CommentsBug in stand-alone MS Sentinel MITRE tactics
I setup a new Analytic rule where I had selected multiple tactics/techniques combinations. When I create an incident from that rule, only one of the tactics/techniques actually show up in the stand-alone MS Sentinel UI as well as in the SecurityIncident table. It isn't even the first one I selected; it is the last one. I did double check the Analytic rule and all the tactics/techniques are selected. If I look at the incident using the MS Sentinel REST API, it does show that all the tactics/techniques are there as well as if I look in the M365 portal (I have my MS Sentinel instance linked). Heck, even the Graph Query will show them all (after expanding the incident to show the alerts as well). Has anyone noticed this recently? Is it a bug or another new "feature"?98Views0likes0CommentsCan we deploy Bicep through Sentinel repo
Hi there, Im new here, but π .... With the problem statement being "Deploying and managing sentinel infrastructure through git repository. I had looked into Sentinel Repository feature which is still in Preview. With added limitations of not being able to deploy watchlists or custom log analytical functions ( custom parsers ). There is also a limitation of deploying only ARM content My guess would be that the product folks at msft are working on this π My hypothesized (just started the rnd, as of writing this) options would be to Fully go above and beyond with Bicep; Create bicep deployment files for both the rules as well as their dependencies like LAW functions, watchlists and the whole nine yards. Need to write pipelines for the deployment. The CI/CD would also need extra work to implement Hit that sweet spot; Deploy the currently supported resources using sentinel repo and write a pipeline to deploy the watchlists using Bicep. But not sure if this will be relevant to solutions to clients. When the whole shtick is that we are updating now so we dont have to later. Go back to the dark ages: Stick to the currently supported sentinel content through ARM & repo. And deploy the watchlists and dependencies using GUI π I will soon confirm the first two methods, but may take some time. As you know, I may or may not be new to sentinel...or devops.. But wanted to kick off the conversation, to see how close to being utterly wrong I am. π Thanks, mal_sec83Views1like0CommentsWhy maximum supported DataFlow count is 10 in DCR?
Is there any technical reason why a DCR can support maximum 10 dataflows? There are already 10 ASim tables. If we want to combine standard tables with ASim tables in one DCR, that is currently not possible. It makes the process complicated. Also is that the same reason why designated ASim table count is currently 10? :)58Views0likes0CommentsUsing Playbook_ARM_Template_Generator
