A port scan is as it sounds - someone is using a tool or utility to scan
your IP to see what ports are listening and responding. This provides them
information on what ports and services you have running. They can then
tailor an attack to those specific ports. You can't really stop someone
from scanning your ports unless you have some software or hardware that does
intrusion detection.
With some intrusion detection hardware and software applications, it will
detect a port scan and temporarily or permanently block all traffic from
that source IP address. Of course if they are spoofing their source IP
address it won't be all that effective.
Hope that helps.
