I have a dedicated server and last week server has been hacked. I changed all of paswords to strongly and Change RDP Scope to my ip addresses.
When i enter the Event Viewer Security tab it is showing Too many Audit failure i show below.

You can see every 4-10 seconds my audit log is adding new audit failure. Is that hacking attempt or anything else? And if it is a hacking attempt how can i prevent this?
