note:
- It appears that the event id 5712 event never occurs. |
made num_id a dictionary instead of a list. Keys of dictionary: Years Values of dictionary: List of numbers for each year
Deleted relationship ID. No need to add relationship since ossemDM.py script will add relationship id after the PR is merged :D
|
We need to remove 5712 from the RPC file and create another one to also cover enpodint/host RPC ETW events. SilkETW would be easy to use for a basic scenario. |
- updated schema for both events - I need to validate if user and process context of event 5712 could be used to generate new relationships: user called RPC method, process called rpc method - I need to validate schema for dce_rpc event and potential change in behavior to: rpc method called from ip or port - I need to validate attack mapping section
