Hello there,

 

We want to apply IPS signature MS.OWA.Brute.Force (ID 39292) on a Microsoft Outlook Web App 2019 server but according to the documentation it is not supported.

 

Is it known when this signature will get support for Microsoft Outlook Web App 2019 server?

Today I received response from the Fortinet IPS team:

 

We've gathered new traffic for Exchange server 2019 and determined that the same signature can be used to stop similar brute force attacks. We have updated the FortiGuard encyclopedia to correctly reflect that the signature supports newer versions of the Exchange server and this updated entry should be released soon. Thank you for bringing this to our attention.
