As yet, apps under Gnome under Linux have few exploitable weaknesses
*if* the OS and apps are kept up to date - with due respect to security
reports (CERT, SANS, vuln etc.) The standard firewall that is included
with all (?) Linux versions is effective and safe, a separate utility
makes the firewall logs easy to read (html-formatted output).

I could previously use Linux for everything to do with my Internet
banking, except confirming a money transaction, which demanded Internet
Explorer 6 for implementing non-revocable actions. Getting onto the
Internet under Windows XP always scares the heck out of me; I complained
to my bank and was never so pleased as when I learned that there was  an
alternative for Unix/Linux users.

One thing that still amazes me, is that people who buy PCs blithely go
ahead and install their new XP-based computer with DSL connections and
all, without extra software and without being aware of the consequences.
No-one seems to warn them; not the computer salesman, their ISP nor
anyone else. Reading my firewall logs, every day as I do, is proof of
