Hello, everyone!
Guys, we have a publication of OWA Exchange 2010.
We are having many attempts to brute force and consequently blocking users accounts.
If we block port 443 to close OWA we stop other Exchange services, such as autodiscover... etc.
Is there anything we can do to stop these sonicwall-level attacks?
Has anyone been through this?
The model is an NSA 2600 - firmware 6.5.4.5-53n
