Latest days I have recieved some short (1sec.) port scanns.

What can  be the purpouse of these, besides just being irritateing  ???

Can such short scanns be of any trouble?

I have what I bealieve is one of the best soft firewalls. Is it possible to
rais security without a hardware firewall?

If your machine and a compormise the scan was looking for that could come
right through the PW, it could be trouble. If you don't have that, then it's
no trouble. However, the O/S and the PFW solution does use the machine's
resouces to stop it and your machine could be doing other things for you
instead of that.

If you're using Win 2k or  XP you can use IPsec to supplement the personal
FW/packet filter.

On the other hand, I don't trust anything that runs with the O/S that can be
attacked like the O/S can be attacked,  taken down, circumvented or defeated
as a first line of defense.

A $20 NAT router is a good first line of defense and sits in front of the
machine and fends off scans, attacks and background noise that never reach
the machine where the O/S and PFW solution have to deal with it.
