These following three things have been in my mind for some time now.  Are
they still effective or are they not?

1. TEMPEST Hacking
2. Encryption, Traditional
3. Closed-Source Software

TEMPEST is the use of signal emissions from electronics to be able to see
computer screens at a distance by reconstructing those emissions to
reconstruct the images on the screen

TRADITIONAL ENCRYPTION is public and symmetric encryption methods, one using
a shared key and the other using a secret key.  With the advent of the first
comercially produced quantum computer from IBM this past year do we have to
reconsider our use of traditional cryptographic methods?

CLOSED-SOURCE SOFTWARE is non-peer-reviewed software that trys to implement
security by the us of obscurity.  Its true that its difficult to
reverse-engineer software, but it certainly can be done with an interactive
disassembler.

So ... effective or pooched?  What's the word?
