[Dshield] port access

You might be confusing incoming v. outgoing. For web, you need to connect
outgoing to port 80, but that's on the remote server.

For incoming ports, very few need to be open by default.

If you want (IMO) the best protection without having to worry about the O/S
that you are running, I would recommend using a NAT router. Assuming you
have cable or DSL, the router would do most of the port blocking for you.
Then you don't have to worry so much about the port blocking.

Hope this helps,

Horray for people who use Win NT!!  But what about
the rest of us??
All efforts to find out how to manage port access
in Windows 98 have been fruitless.
Maybe its impossible.
The few scraps of info that are available 
contradict one another.
I hear that no one needs port 80 open unless they
are running a server, at the same time I can't get
on the internet unless ports 80 and 53 are open.

Another sobering experience for a novice is to 
block ports in Zone Alarm and watch them running
wide open in CommView.

Wandering aimlessly in search of security in a sea
of useless gibberish.
                         Sincerely;  Mel.

Just thought I would share this with everyone on this list, maybe it will
come in handy for some of you. We found this neat little tool called Active
Ports. Here is the description off their website:

Active Ports - easy to use tool for Windows NT/2000/XP that enables you to
monitor all open TCP and UDP ports on the local computer. Active Ports maps
ports to the owning application so you can watch which process has opened
which port. It also displays a local and remote IP address for each
connection and allows you to terminate the owning process. Active Ports can
help you to detect Trojans and other malicious programs.
