“sealed In a
of the ocean.” That’s the oft-quoted description of
what it takes to make a computer reasonably secure.
obviously, in the Internet age or any other, such a
machine would be fairly useless as well.
We live in interesting times. That computer on
your desktop embodies the contradiction that faces
a security engineer in the 21st century. It must be
kept safe; and a lot of time, effort, and money is spent
attempting to do exactly that. firewalls are built to
separate that machine from the Internet. Security
audits tell us what programs must be deleted and what
permissions changed so that the machine cannot be
compromised. Virus checkers test all new software
loaded on the machine for malicious content.
