When it comes to excluding legitimate behaviours from BIOC rules, as far as I can see, there are 3 options:
What is the recommended way and differences between these methods?
I'm not saying this is the "recommended" way for excluding legitimate behaviors, but what I have done so far.
When an alert is created, and verifying that it is legitimate, I add it as an alert exclusion.
The thought being that the alert exclusion would be a smaller print versus excluding the whole BIOC rule.
Hope that helps,
Hi @Balaraju both rule (alert) exceptions and alert exclusions exist in Cortex XDR.
When you exclude an alert, the alert will still be triggered by the agent and sent to XDR tenant. However, it will not be stitched into an incident. Here the action is performed by the XDR tenant. The alerts will appear in the Alerts table.
On the other hand, an alert exception will cause the alert not to be triggered by the agent. The action is performed by the agent.
