Hi,
I am new to ISA as our company only had the system installed a few
months ago. Everything seemed to be okay, but we have started getting
the following alert, on a fairly regular basis.
"ISA Server detected an Internet Protocol (IP) half-scan attack from IP
address 64.xx.x.xxx".
Does this mean our system has been compromised?
I have scanned for viruses, but found none. I have checked and double
checked the packet filters and they also seem fine.
Any advice you can give would be greatly appreciated.
Thanks
Kevin
