Incident Missing Entities
Good morning! I would like to have some clarification on how entities work. Yesterday I found out that if I have 2 entities of the same type (In this particular case, two entities of the type Account), with the same identifier (originally, both share the identifier 'Name'), Sentinel appears to throw away one of them, or both in some instances, and when the alert generates an incident, the entities defined won't appear. I have switched out the identifier on both account types to something different, but until an incident gets triggered, I can't confirm if this will fix the original issue. So my questions are An analytic rule can or can't have two entities of the same type defined? If yes, that means that they need to have different identifiers. Is this a correct asumption? Some identifiers expect a certain type of value to be assigned, that means that eventually, I can ran out of identifiers for my entities or face the added complexity of dealing with types when returning values from my KQL query What could happen if I map an identifier to something that matches the type but not what that identifier represents? in this case, for Account, we have the identifier ObjectGuid. If I assign a value type string to it, that is not a guid, wouldn't that mess up something else in the background? Example, incident grouping If I move instead to use Sentinel Entities, which appear to be the 'general' option, I could only use one, since I only have 'entity' as available identifier, looping back to the problem of can have only one type of identifier for identity type. Thanks in advance
KQL: setting query time leads to problem in watchlist column projecting
Hello to the community! I have stumbled upon a very strange issue when using watchlists. I have a watchlist with 2 columns (userPrincipalName,allowedActivity) that I am then using to whitelist activities. Watchlist is imported using: let WhitelistedUsers = _GetWatchlist("testQuery") | project userPrincipalName, allowedActivity; Then I wanted to set it to a specific time frame to test it on given data set: set query_now = datetime("1/14/2022, 1:45:46.556 PM"); Problem is that when setting my query for a specific time, I get the following error from the watchlist: 'project' operator: Failed to resolve scalar expression named 'userPrincipalName'. Commenting the set query_now solves the project problem (not my problem though). I tried to set the time before and after watchlist import but that does not solve the issue. I could not find any posts around the topic (quite a specific one), so anyone observed similar behaviors or has a possible explanation? I can probably work around the set query_now with other functions but I gotten used to it, and find this behavior extremely strange
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. ThxxUnified SecOps XDR
Hi, I am reaching out to community to seek understanding regarding Unified SecOps XDR portal for Multi-tenant Multi-workspace. Our organization already has a Azure lighthouse setup. My question is if M365 lighthouse license also required for the Multi-tenant Multi-workspace in unified SecOps XDR portal?
Zoom logs into Sentinel
Hi I am reaching out to community member because facing a hustle while integrating the Zoom with Sentinel. while following the document provided inside the Zoom data connector, deployed an App over the zoom extracted the required information, create function app on Azure and provided the account ID, client ID, Client secret everything but facing one error that the account has not audio conference plan function app is running successfully but in the invocation logs its showing this audio conference plan to make sure we have purchased the zoom audio conference plan but still its giving us the same error. If anyone has done this please please share your experience with us how did you integrate zoom with sentinel because from last two months we are struggle with it.
