Default threat ID correlation for action

Not applicable

Hi all,

I was searching for a while and could not find the answer to this question.

By default, does a Palo Alto block every instance a threat ID (that is enabled) is seen or does it wait until 1 threat ID hits 5 times in 1 minute (for example).

I would think it would be the former, but was searching for confirmation.

Thanks

Hello Craig,

If threat ID has default action RESET than it will stop in first instance. So, it depends on default action of threat.

There is a different case in Vulnerability. Lets say there is a vuln. for bruteforce. And Palo Alto conclude it bruteforce if there are more than 60 attempts in 1 minutes. So in these type of scenarios we check the hits.

Best thing is to understand threat details, firewall will behave case to case bases.

Hardik,

Let's take HTTP Unauthorized Brute-force Attack (40031) for example and it's set to the default action of allow. You are saying, there would have to be 60 attempts within 1 minute before an alert would be created?

Do you have a link to these figures?

Hi Craig,

You are right about the behavior, certain number of attempts within 1 minute can trigger vulnerability 40031. And it will only generate a Threat log, because default action is Alert, not Reset.

Hello craigmueller,

Here is the link you are looking for :

Hope that helps!

Thank you for the link.

Are there separate lists for each group of signatures? Like 40022 or 40008.

Hi Craig,

There may not be, but why do you need it?

I was looking for more information on the threat IDs and what triggers the alerts.

Hi Craig,

Normally PAN doesnt disclose that information unless asked by specific customer for specific ID.

ok, thanks everyone for the information
