Hi Paul - I am interested in knowing how you prevent intrusion with
your firewall when it is a known fact that post 9/11 companies that
develop such leave ports open for "Big Brother" as required. Remember
"Green Lantern", "Carnivore" and the like are roaming around and used
by various agencies. Even though a firewall reports that the ports are
blocked, they aren't.

Limiting surfing to only trusted sites does limit vulnerability, but
for the last couple of years, Google, Yahoo, Fbook, Youtube are
compromised by hackers installing "Antivirus 2009", "Antivirus 2010",
etc. viruses.

With a long list of sites improperly setting cookies, passwords and
usernames are easily compromised when a person visits other sites.
Most importantly,   how do you verify that the Internet Service
provider has not been compromised? Using SSL to pass passwords is
still not 100 percent safe as people may think because the real
problem lies in what and where the web site stores your information on
the server.

How do you thwart these possible and other  intrusion nodes?
