[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.
Sentinel incident playbook - get alert entities
Hi! My main task is to get all alerts (alerts, not incidents) from sentinel (analytics rules and Defender XDR) to external case management. For different reasons we need to do this on alert level. Alert trigger by design works perfectly, but this does not trigger on Defender alerts on Sentinel, only analytic rules. When using Sentinel incident trigger, then i'm not able to extract entities related to alerts, only incident releated entities. Final output is sent with HTTP post to our external system using logic app. Any ideas how to get in logic app all alerts with their entities?
Behavior Analytics, investigation Priority
Hello, Regarding the field investigation Priority in the Behavior Analytics table, what would be the value that Microsoft considers to be high/critical to look into the user's account? By analyzing the logs i would say, 7 or higher, if someone could tell me, and thank you in advance.Update 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.
Fetching alerts from Sentinel using logic apps
Hello everyone, I have a requirement to archive alerts from sentinel. To do that I need to do the following: Retrieve the alerts from Sentinel Send the data to an external file share As a solution, I decided to proceed with using logic apps where I will be running a script to automate this process. My questions are the following: -> Which API endpoints in sentinel are relevant to retrieve alerts or to run kql queries to get the needed data. -> I know that I will need some sort of permissions to interact with the API endpoint. What type of service account inside azure should I create and what permissions should I provision to it ? -> Is there any existing examples of logic apps interacting with ms sentinel ? That would be helpful for me as I am new to Azure. Any help is much appreciated !
Can we deploy Bicep through Sentinel repo
Hi there, Im new here, but 😅.... 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 😋 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 🙃 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. 😎 Thanks, mal_sec
Working around the "Analytics rule start time" for mass deploying using Workspace Manager
Hi! What are some of your thoughts/experiences of working around the "The Analytics rule start time must be between 10 minutes and 30 days from now" for mass deploying using Workspace Manager? Lets say I have 100 Analytic rules that I want to deploy to current customer using Workspace manager. This goes fine, but when a new customer arrives 1 month later, I have to redo the start time of all the Analytic rules that hasn't been changed in the last month. Doing this manually is just not an option. What I can see as a possible solution, is to use Repositories at the same time, where I would use a script to mass update the start time for all rules I need. Then sync back to Analytic rules and deploy again to new customer.Sentinel 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?AITM Attack - Canary URL
Hello. I am trying to work through the configuration in this article; https://ironpeak.be/blog/azure-detecting-aitm-attacks/ I created the following logic app; The generated URL has been added to a CSS file and uploaded as outlined in that article, and the branding changes are active. When someone logs in to something like the Azure portal the logic app is triggered, but the condition is always "false". If I look at the output the "Referer" is exactly as it should be for the condition to be true; Any help where I am going wrong would be greatly appreciated.
