[DevOps] dps.sentinel.azure.com no longer responds
Hello, Ive been using Repository connections in sentinel to a central DevOps for almost two years now. Today i got my first automated email on error for a webhook related to my last commit from the central repo to my Sentinel intances. Its a webhook that is automticly created in connections that are made the last year (the once from 2 years ago dont have this webhook automaticly created). The hook is found in devops -> service hooks -> webhooks "run state change" for each connected sentinel However, after todays run (which was successfull, all content deployed) this hook generates alerts. It says it cant reach: (EU in my case) eu.prod.dps.sentinel.azure.com full url: https://eu.prod.dps.sentinel.azure.com/webhooks/ado/workspaces/[REDACTED]/sourceControls/[REDACTED] So, what happened to this domain? why is it no longer responding and when was it going offline? I THINK this is the hook that sets the status under Sentinel -> Repositories in the GUI. this success status in screenshoot is from 2025/02/06, no new success has been registered in the receiving Sentinel instance. For the Sentinel that is 2 year old and dont have a hook in my DevOps that last deployment status says "Unknown" - so im fairly sure thats what the webhook is doing. So a second question would be, how can i set up a new webhook ? (it want ID and password of the "Azure Sentinel Content Deployment App" - i will never know that password....) so i cant manually add ieather (if the URL ever comes back online or if a new one exists?). please let me know.
Issue while deploying Sentienl Rules
I know that when deleting a Sentinel rule, you need to wait a specific amount of time before it can be redeployed. However, in this tenant, we've been waiting for almost a month and are still getting the same deployment error ('was recently deleted. You need to allow some time before re-using the same ID. Please try again later. Click here for details'). I still want to use the same ID ect. Does anyone have any idea or similar issue why it's still not possible after waiting for about a month?
Trend Micro Vision One Connector Not working
Hi All, Before I get nuked in the comments to raise an issue on the Sentinel Repo. Here me out 😇 Around a month ago, the logs stopped ingesting. A quick snoop around revealed the reason. But I'm not sure if I should raise an issue, or try to fix the issue, risking voiding any future support I can get, since the connector and the app that comes with it are market solutions. Function app was not running due to a dependency issue. Spotted this on the diagnostic logs, under the "exceptions" table. "module named _cffi_backend not found" a python package google tells me, thats used to interact with C code. So logically, I need to find the requirement.txt and make sure the dependency is there. Also make sure the python version on the runtime and Azure matches, The logs were initially flowing as usual . I had completed integrating Trend Micro using Azure Functions based connector around 7 months ago. Worked like a toyota helix until now. So once again, would like to know the community's thoughts on it. ThxxUpdate content package Metadata
Hello Sentinel community and Microsoft. Ive been working on a script where i use this command: https://learn.microsoft.com/en-us/rest/api/securityinsights/content-package/install?view=rest-securityinsights-2024-09-01&tabs=HTTP Ive managed to successfully create everything from retrieving whats installed, uninstalling, reinstalling and lastly updating (updating needed to be "list, delete, install" however :'), there was no flag for "update available"). However, now to my issue. As this work like a charm through powershell, the metadata and hyperlinking is not being deployed - at all. So i have my 40 content packages successfully installed through the REST-api, but then i have to visit the content hub in sentinel in the GUI, filter for "installed" and mark them all, then press "install". When i do this the metadata and hyperlinking is created. (Its most noticeable that the analytic rules for the content hubs are not available under analytic rules -> Rule templates after installing through the rest api). But once you press install button in the GUI, they appear. So i looked in to the request that is made when pressing the button. It uses another API version, fine, i can add that to my script. But it also uses 2 variables that are not documented and encrypted-data. they are called c and t: Im also located in EU and it makes a request to SentinelUS. im OK with that, also as mentioned, another API version (2020-06-01) while the REST APi to install content packages above has 2024-09-01. NP. But i can not simulate this last request as the variables are encrypted and not available through the install rest api. They are also not possible to simulate. it ONLY works in the GUI when pressing install. Lastly i get another API version back when it successfully ran through install in GUI, so in total its 3 api versions. Here is my code snippet i tried (it is basically a mimic of the post request in the network tab of the browser then pressing "install" on the package in content hub, after i successfully installed it through the official rest api). function Refresh-WorkspaceMetadata { param ( [Parameter(Mandatory = $true)] [string]$SubscriptionId, [Parameter(Mandatory = $true)] [string]$ResourceGroup, [Parameter(Mandatory = $true)] [string]$WorkspaceName, [Parameter(Mandatory = $true)] [string]$AccessToken ) # Use the API version from the portal sample $apiVeri = "?api-version=" $RefreshapiVersion = "2020-06-01" # Build the batch endpoint URL with the query string on the batch URI $batchUri = "https://management.azure.com/\$batch$apiVeri$RefreshapiVersion" # Construct a relative URL for the workspace resource. # Append dummy t and c parameters to mimic the portal's request. $workspaceUrl = "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroup/providers/Microsoft.OperationalInsights/workspaces/$WorkspaceName$apiVeri$RefreshapiVersion&t=123456789&c=dummy" # Create a batch payload with several GET requests $requests = @() for ($i = 0; $i -lt 5; $i++) { $requests += @{ httpMethod = "GET" name = [guid]::NewGuid().ToString() requestHeaderDetails = @{ commandName = "Microsoft_Azure_SentinelUS.ContenthubWorkspaceClient/get" } url = $workspaceUrl } } $body = @{ requests = $requests } | ConvertTo-Json -Depth 5 try { $response = Invoke-RestMethod -Uri $batchUri -Method Post -Headers @{ "Authorization" = "Bearer $AccessToken" "Content-Type" = "application/json" } -Body $body Write-Host "[+] Workspace metadata refresh triggered successfully." -ForegroundColor Green } catch { Write-Host "[!] Failed to trigger workspace metadata refresh. Error: $_" -ForegroundColor Red } } Refresh-WorkspaceMetadata -SubscriptionId $subscriptionId -ResourceGroup $resourceGroup -WorkspaceName $workspaceName -AccessToken $accessToken (note: i have variables higher up in my script for subscriptionid, resourcegroup, workspacename and token etc). Ive tried with and without mimicing the T and C variable. none works. So for me, currently, installing content hub packages for sentinel is always: Install through script to get all 40 packages Visit webpage, filter for 'Installed', mark them and press 'Install' You now have all metadata and hyperlinking available to you in your Sentinel (such as hunting rules, analytic rules, workbooks, playbooks -templates). Anyone else manage to get around this or is it "GUI" gated ? Greatly appreciated.
Microsoft Defender Vulnerability Management Data in Sentinel
Anyone know when Microsoft Defender Vulnerability Management data will be available in Microsoft Defender XDR connector in Sentinel? If it won't be available soon, what is the best way to collect Vulnerability Management data to Sentinel? ThanksSentinel Solution Deployment via GitHub
Over the past couple years I have been working exclusively with LogRhythm and while I have deployed Sentinel a few times in the past, I have never attempted to do so using GitHub Actions. I seem to be relatively close to getting it deployed but have been struggling for the last couple days and have been unable to find (or overlooked) documentation to guide me in the right direction, so I thought I'd reach out to find out if anyone can help me out. Goals Central management of Sentinel across multiple tenants using Lighthouse Content such as Analytic Rules, Hunting Queries, Playbooks, Workbooks.. must be centrally managed across each tenant. I will have limited access to tenants and need a simple templated deployment process to handle the majority of the Sentinel deployment in tenants, ideally, I will provide the client with a deployment template and once deployed, it will have the the same content as the central management tenant. I have not yet decided whether to use Workspace manager, however, I will need to protect intellectual property so this will likely be a requirement (MSSP) I have been trying out the GitHub deployment and have mostly been running into issues with the solution deployment since the ARM Templates I have been creating don't seem to work. I get "Failed to check valid resource type." errors followed by "The file contains resources for content that was not selected for deployment. Please add content type to connection if you want this file to be deployed." warnings for most content. I have been able to get some working, specifically the Analytic Rules and Playbooks, and have not spent time on the Hunting Queries or Workbooks yet since I have rather been focused on the Solutions and while I make a bit of progress each day, I still feel like I am missing something simple, most likely related to the deployment script which Sentinel generates when connected to GitHub? Perhaps I am not deploying the required resources in the correct order? Now I am in the very early stages of planning and may very well not need to deploy solutions via GitHub if using the workspace manager (still to be verified), but it is killing me because I have not been able to figure it out in the last couple days! Does anyone know of a document that explains the process for those of us that don't spend a considerable amount of time using GitHub/DevOps?
AMA on client devices
We have followed the guidance outlined below to get AMA installed and working on a few test client devices and they are sending logs to the Event table in our Sentinel workspace. https://learn.microsoft.com/en-us/azure/azure-monitor/agents/azure-monitor-agent-windows-client The problem we face is with the Windows Security Events via AMA connector. Is there a supported way to get client devices to populate security events into the SecurityEvent table? I see the events in the 'Event' table but not the SecurityEvent table. It seems like the Sentinel security events connector only sees DCR's that are created in Sentinel, it does not see the DCR's that are created outside of Sentinel. Is that a bug or by design? Any guidance is appreciated, we have had data in SecurityEvent from client devices via MMA for a few years and expected to be able to continue to ingest them properly via AMA.Defender XDR connector
I'm confused about what I am seeing for installed connectors in Sentinel. Within "Data connectors" I have the Microsoft Defender XDR connector and it is enabled. The description is; "Microsoft Defender XDR is a unified, natively integrated, pre- and post-breach enterprise defense suite that protects endpoint, identity, email, and applications and helps you detect, prevent, investigate, and automatically respond to sophisticated threats" If I go to "Content hub" and search for "Status: Installed" I don't see that connector. If I change the filter to "Status: Not installed" and search for Microsoft Defender XDR I see this solution; Based on the difference in number of Analytic rules and Queries associated with the two solutions they are not the same. Can someone shed some light on this? Does one supersede the other? And why when I search for installed solutions does the one I have installed not show up? Thanks
