We have recently upgraded from a PIX 515e to an ASA 5510 and am having problems with SYN attacks to 2 web servers on our DMZ which we did not have previously with the 515e.
Currently scanning attacks reads 121 and SYN attacks is saying 92

Is there anything we can do? the basic security is set.
Does anything in the ACL need changing to prevent this?


Thanks,

You can limit embryonic connections, which is usually what's done to combat syn attacks.  See http://www.cisco.com/en/US/products/ps6120/products_tech_note09186a00809763ea.shtml
