I just want to get an idea if we are\were targeted and report up to management as this issue progresses. So, with two AZs, each PA instance handles In this case, we will start hunting with unsampled or non-aggregated network connection logs from any network sensor logs. A data filtering log will show the source and destination IP addresses and network protocol port number, the Application-ID used, user name if User-ID is available for the traffic match, the file name and a time-stamp of when the data pattern match occurred. The logic of the detection involves various stages starting from loading raw logs to doing various data transformation and finally alerting the results based on globally configured threshold values. Even if you follow traditional approaches such as matching with IOCs, application or service profiling, various type of visualizations , due to the sheer scale of the data ,results from such techniques are not often directly actionable for analysts and need further ways to hunt for malicious traffic. Optionally, users can configure Authentication rules to Log Authentication Timeouts. Details 1. How do you do source address contains 10.20.30?
