Whitehats are mostly losing. Network administrator that has no sense of
security are losing. Are all network open to something? Yep, but you can
reduce your risk if you try. No network is safe from hackers 100% and no
hacker is safe from the law 100%. We all take our chances - sometimes on
both sides...

Glenn:
Not to take issue with the performance of encryption, but what good is
performance when it's all spent processing spam, malware, trojans,
spyware and all the other cr*p that downloads.
Even things like spybot, zone alarm etc. do not  prevent any of the junk
that gets loaded thru mail and port 80, plus any other vulnerabilities
that continually open up.

I would gladly take performance hits for reliability and the end of
endless spam, vuls, and spyware that constantly attach to  my clients as
well as myself.  

Anyone in the real world knows how impossible it is to totally lock down
a large commercial network.  To do business you need to open at least
one window to the hellish nightmare of the internet.  Plus router,
firewall, switch, modem, atm endless list of vulnerable systems... It is
a never ending battle, and for the most part the white Hats are losing.
So what is the alternative?

Go to a totally secure network computing system like the military?

It seems we may have no choice.

Encryption is one scheme that gives access control. It is one of the
more expensive alternatives out there for this, and people using it
often get the key management wrong and vitiate their entire efforts
while sweeping the problems under the rug.

When I invented the cryptodisk back in the late 70s I noticed the first
version (using a DES algorithm) would allow the processor either to be
doing useful work, or encrypting/decrypting disk. I therefore added a
much weaker but faster algorithm as an alternative (for more benign
environments) that at least permitted both.

Machines today are much more capable, but overdone encryption is still
capable of eating serious amounts of their performance.

M$ should just bite the bullet and re-write windows with security in
mind, give it a true process scheduler, multi-user
with windows as a client server processes.  Build in 256 bit encryption
and secure communications between processes and external communication
with no unencrypted traffic.  That would shut down a lot of these
mindless security leaks.  All mail should be encrypted and
point-to-point, with the mail servers only able to re-direct and
broadcast mail with authentication.   Maybe we could slow a lot of  the
hacking down  and spam.  But again until the market place demands it M$,
Linux and everybody else it's business as usual.

Keeps us employed I guess.
