Hi I want to create a playbook to automatically revoke session user when incident with specifics title or gravity is created. But after some test the playbook is'nt run autimacally, it work when I run it manually. I did'nt find what I do wrong. See the image and the code bellow.

Logic app - Escaped Characters and Formatting Problems in KQL Run query and list results V2 action
I’m building a Logic App to detect sign-ins from suspicious IP addresses. The logic includes: Retrieving IPs from incident entities in Microsoft Sentinel. Enriching each IP using an external API. Filtering malicious IPs based on their score and risk level. Storing those IPs in an array variable (MaliciousIPs). Creating a dynamic KQL query to check if any of the malicious IPs were used in sign-ins, using the in~ operator. Problem: When I use a Select and Join action to build the list of IPs (e.g., "ip1", "ip2"), the Logic App automatically escapes the quotes. As a result, the KQL query is built like this: IPAddress in~ ([{"body":"{\"\":\"\\\"X.X.X.X\\\"\"}"}]) Instead of the expected format: IPAddress in~ ("X.X.X.X", "another.ip") This causes a parsing error when the Run Query and List Results V2 action is executed against Log Analytics. ------------------------ Here's the For Each action loop who contain the following issue: Dynamic compose to formulate the KQL query in a concat, since it's containing the dynamic value above : concat('SigninLogs | where TimeGenerated > ago(3d) | where UserPrincipalName == \"',variables('CurrentUPN'),'\" | where IPAddress in~ (',outputs('Join_MaliciousIPs_KQL'),') | project TimeGenerated, IPAddress, DeviceDetail, AppDisplayName, Status') The Current UPN is working as expected, using the same format in a Initialize/Set variable above (Array/String(for IP's)). The rest of the loop : Note: Even if i have a "failed to retrieve" error on the picture don't bother with that, it's just about the dynamic value about the Subscription, I've entered it manually, it's working fine. What I’ve tried: Using concat('\"', item()?['ip'], '\"') inside Select (causes extra escaping). Removing quotes and relying on Logic App formatting (resulted in object wrapping). Flattening the array using a secondary Select to extract only values. Using Compose to debug outputs. Despite these attempts, the query string is always malformed due to extra escaping or nested JSON structure. I would like to know if someone has encountered or have the solution to this annoying problem ? Best regards
How to exclude IPs & accounts from Analytic Rule, with Watchlist?
We are trying to filter out some false positives from a Analytic rule called "Service accounts performing RemotePS". Using automation rules still gives a lot of false mail notifications we don't want so we would like to try using a watchlist with the serviceaccounts and IP combination we want to exclude. Anyone knows where and what syntax we would need to exlude the items on the specific Watchlist? Query: let InteractiveTypes = pack_array( // Declare Interactive logon type names 'Interactive', 'CachedInteractive', 'Unlock', 'RemoteInteractive', 'CachedRemoteInteractive', 'CachedUnlock' ); let WhitelistedCmdlets = pack_array( // List of whitelisted commands that don't provide a lot of value 'prompt', 'Out-Default', 'out-lineoutput', 'format-default', 'Set-StrictMode', 'TabExpansion2' ); let WhitelistedAccounts = pack_array('FakeWhitelistedAccount'); // List of accounts that are known to perform this activity in the environment and can be ignored DeviceLogonEvents // Get all logon events... | where AccountName !in~ (WhitelistedAccounts) // ...where it is not a whitelisted account... | where ActionType == "LogonSuccess" // ...and the logon was successful... | where AccountName !contains "$" // ...and not a machine logon. | where AccountName !has "winrm va_" // WinRM will have pseudo account names that match this if there is an explicit permission for an admin to run the cmdlet, so assume it is good. | extend IsInteractive=(LogonType in (InteractiveTypes)) // Determine if the logon is interactive (True=1,False=0)... | summarize HasInteractiveLogon=max(IsInteractive) // ...then bucket and get the maximum interactive value (0 or 1)... by AccountName // ... by the AccountNames | where HasInteractiveLogon == 0 // ...and filter out all accounts that had an interactive logon. // At this point, we have a list of accounts that we believe to be service accounts // Now we need to find RemotePS sessions that were spawned by those accounts // Note that we look at all powershell cmdlets executed to form a 29-day baseline to evaluate the data on today | join kind=rightsemi ( // Start by dropping the account name and only tracking the...

Researching a rule template "FailedLogonToAzurePortal"
Hello, I have the template rule "FailedLogonToAzurePortal"(https://github.com/Azure/Azure-Sentinel/blob/master/Detections/SigninLogs/FailedLogonToAzurePortal.yaml) and there is a column of data that I don't understand. The column is "FailedLogonCount" and it was showing inconclusive data because it was showing more data than it was... Here is an example: The issue states that 38 login failures have been detected, but if I investigate in the non-interactive login logs I only see one failure which matches the error code type "50173" but this only shows me one failure, I don't understand where the remaining 37 failures come from... Can you help me?, I am a beginner in KQL and I don't think I understand the context of the alert. Regards.
Scheduled Analytics Rule not triggering...
Hello, I am trying to trigger the following KQL query in a custom scheduled Analytics Rule... It is to identify ANY Global Administrator and verify if they have committed any activity (Sign-in) over the last 24 hours. Simple testing is to get a Global Administrator to sign in within the last 24 hours. Now the query triggers and returns records when run in the Logs pane... What I have noticed is that when activated in a custom-scheduled Analytics Rule, it fails to return records! Now the time range set for the analytics rule (query frequency & lookback duration) aligns properly with the query logic or any log ingestion delay. Query scheduling Run query every: 1 day Lookup data from the last: 1 day The funny thing is, when testing the KQL query in the Analytics Rule and Set rule logic/View query results, if the FIRST ATTEMPT returns no results (in the simulation), after repeatedly testing (clicking the test link), it DOES return records! Why is there a time-lag? How can I ensure the query triggers correctly, returning records accordingly, and related Incidents? This is the KQL query... let PrivilgedRoles = dynamic(["Global Administrator"]); let PrivilegedIdentities = IdentityInfo | summarize arg_max(TimeGenerated, *) by AccountObjectId | mv-expand AssignedRoles | where AssignedRoles in~ (PrivilgedRoles) | extend lc_AccountUPN = tolower(AccountUPN) | summarize AssignedRoles=make_set(AssignedRoles) by AccountObjectId, AccountSID, lc_AccountUPN, AccountDisplayName, JobTitle, Department; SigninLogs | where TimeGenerated > ago (1d) | extend lc_UserPrincipalName = tolower(UserPrincipalName) | join kind=inner PrivilegedIdentities on $left.lc_UserPrincipalName == $right.lc_AccountUPN | project TimeGenerated, AccountDisplayName, AccountObjectId, lc_AccountUPN, lc_UserPrincipalName, AppDisplayName, ResultType, ResultDescription, IPAddress, LocationDetailsHow to Filter Logs by User Parameter in Sentinel Workbook KQL?
Hi everyone, I am trying to create a Sentinel Workbook with a dropdown parameter to filter logs based on a selected username. The goal is to dynamically toggle between users and see logs related to each user, including total data downloaded, accessed repositories, and timestamps. Here’s what I have so far: Syslog | extend grpc_method_ = tostring(parse_json(SyslogMessage).["grpc.method"]) | extend grpc_request_glProjectPath_ = tostring(parse_json(SyslogMessage).["grpc.request.glProjectPath"]) | extend username_ = tostring(parse_json(SyslogMessage).username) | extend user_id_ = tostring(parse_json(SyslogMessage).user_id) | where isnotempty(username_) | where trim(" ", username_) == trim(" ", '{{UserParam}}') | extend remote_ip_ = tostring(parse_json(SyslogMessage).remote_ip) | extend response_bytes_ = tostring(parse_json(SyslogMessage).response_bytes) | where Facility == "Local" | where ProcessName <> "ldsclient" | where isnotempty(response_bytes_) //| project TimeGenerated, username_, UserParam, grpc_method_, grpc_request_glProjectPath_, remote_ip_, response_bytes_ I set up a dropdown parameter called userParam, which pulls distinct usernames from the logs using this query: Syslog | extend username_ = tostring(parse_json(SyslogMessage).username) | where isnotempty(username_) | summarize count() by username_ | distinct username_ However, when I select a user from the dropdown, the main query fails. It seems the parameter is not being recognized correctly in the query. How can I properly reference a dropdown parameter in a Sentinel Workbook KQL query? Is there a better way to filter logs dynamically based on a selected user? Any help is highly appreciated!
How to remove string quotes and other things from the parsed syslog message
Hello Sentinel Community, We are ingesting Azure database for Postgresql logs into the log analytical workspace and tried to retrieve the values from the Postgresql log Message coulumn. However, we are getting the values in double quotes and comma from the retrieved values. Below is the sample Pstgresql Message log: Message: 2025-01-22 09:53:35 UTC-6790c01f.259e-FATAL: no pg_hba.conf entry for host "10.150.48.4", user "email address removed for privacy reasons", database "prodxxxx0424", no encryption We used below KQL query and parse kind (mentione below) to get the values of host, user, and database but we got the values like below with double quotes and comma. How to get the values without double quotes. AzureDiagnostics | where Category == "PostgreSQLLogs" | where errorLevel_s == "FATAL" | where Message contains "no pg_hba.conf entry" | parse kind=relaxed Message with * "host" Source_IP "user" UserName "database" DatabaseName Received Values: Thanks, Yugandhar.Cannot access aka.ms/lademo
Hello team, I am Nikolas. I am learning KQL for Microsoft Sentinel. As far as I know, we can access the aka.ms/lademo for demo data. However I cannot access the demo. I tried using VPN, access page from many other devices with different IP address different account. But it does not work. Can you help to confirm if this link is still accessible. I can access the resource last week, but not this week. I am looking forward to hearing from you.
Sentinel query KQL with variables
Hello! I need to use variables as parameters of functions in Sentinel Logs. I have: let t = "Syslog"; let name = "my-Sentinel"; let id = "abc123"; Well, if do this, it works fine: table("Syslog") table(t) workspace("my-Sentinel").table("Syslog") workspace("my-Sentinel").Syslog But i need to work this: worskpace(name).table(t) or let x=strcat("workspace('", name, "')"); let y=strcat("table('", t, "')"); x.y In general seems that the function workspace() doesent work with a variable as parameter, but the function table() if alone it works: workspace("my-Sentinel") -> YES workspace(n) -> NO table("Syslog") -> OK table(t) -> OK Any idea how to make it works? In particulary to do this: workspace(name).table(t) Thanks!!!
