My Sonicwall keep alerting me to port scans, I know they happen all the time but why be alerted if there isn't anything to do about it.
So I ask is there anything to do about it?
Example:
02/28/2012 11:05:04.512 - Alert - Intrusion Prevention - Possible port scan detected - 96.6.82.110, 443, X1, a96-6-82-110.deploy.akamaitechnologies.com - 192.168.0.2, 14037, X1 - TCP scanned port list, 61605, 64862, 61230, 38184, 65130

deploy.akamaitechnologies.com seems like I should know where this is coming from but I'm prety sure I don't have anything port scanning my network I setup.
The IP's change so I can't block or alert the ISP.
Thoughts?
