An interesting read about computer security:

Computer security, as it’s done today by most practitioners, is fundamentally a con. It’s a con the same way that most diet foods and “lose weight fast” schemes are a con: they cost a lot and they only work if you do something sensible that would have worked REGARDLESS of whether you were following the rules of the diet.

The author lists “simple” ideas to keep in mind regarding network security, including Production Systems 101:

10 SET IT UP
20 MAKE IT WORK
30 IF WORKING THEN
40      DON'T F- WITH IT
50 ENDIF
60 IF NOT WORKING
70      FIX IT
80      GOTO 20
90 ENDIF

it's that BASIC (ok, that was a bad one...)

Some of his ideas (including the one above) can be applied to software development.
