Why firewall messages are sometimes so vague

A

AndyHancock

After much web searching, it seems that anyone who has used older
firewalls (e.g Kerio, Sygate) will have been annoyed by messages like
"Generic Host Process for Win32 Services from your computer wants to
connect to some.changing.ip.address", or some outgoing ping (icmp).
The remote destination ip address often resolves to Microsoft or some
large content provider. The application that is doing this is always
nondescriptly described as svchost or tcpip kernel driver. Possible
causes are Windows update checker, Symantec, or possibly McAfee. I
know that Kerio will specify the full path of the executable trying to
connect out in some cases, so I'm not sure this information is so
elusive for these messages. Avast and Diskeeper connections to
outside are certainly reported more specifically than the above. From
the aforementioned web searching, such details are not elusive to
Kerio users. This makes it impossible to maintain a decent set of
firewall rules. I've already disabled automatic windows updates, got
rid of symantec, and such messages continue to occur, though less
often.

How do the more experienced maintainers of home firewalls deal with
this lack of detail in tightening up their firewall rules? I have,
and use, Spybot S&D. I'm hoping that there is a general appraoch that
doesn't entail that a user spend much less than 50% of his or her
computer time dealing with the security aspects. Currently, the
figure is well in excess of 50%, which really raises the question of
whether it is reasonable to convert to Luddite-ism.

Thanks!

Easy-- don't use personal firewalls that nag you all the time. If you're
following basic safe computing practices (keep your software updated,
anti-malware programs updated, and don't run as admin), then the firewall
built in to Windows is all that you need. A firewall's job is to watch your
network port and block inbound traffic that you didn't ask for. It's not the
job of a firewall to try to watch every single outbound connection. Indeed,
smart malware knows how to avoid these kinds of firewalls anyway. I've
written extensively about this in the past see

Yes, I was thinking that a builtin firewall would be handy because it
would recognize all the things that are legit. And won't bug the
user. However, I'm using Windows 2000. As far as I know, I need a
third party firewall.

Correct, Windows 2000 doesn't have a built-in firewall. But, you know, you
really should switch to at least Windows XP and be sure to install service
pack 3 on it when it becomes available on 29 April. If your hardware
supports it, go to Vista. Windows 2000 is really too old to be safe these
days.

It takes alot of resources. This machine runs at several hundred MHz,
has several hundred MB RAM, and the hard disk runs at some
forty-something hundred RPM. It's also missing some of the standard
peripheral interface taken for granted these days. Of course, if I
ever get another machine, XP it shall be, but with luck, it won't
happen soon.
