Our T1 was saturated today and we were being attacked. I checked the logs of our ASA and saw hundreds of the below.
How do we prevent something like this? Our firewall is doing the job, do we have to get the ISP involved?
SL_COMCAST_ASA %ASA-3-710003: TCP access denied by ACL from 116**.167.139/2083 to outside:75.***.11.191/23
