Hi all, I'm afraid I don't concur with this definition. Here's a (rather vague) flaw example that may help clarify what I mean. Think about an error of omission where an API is exposed with no A&A protection whatsoever. This API may have been designed not to have been exposed originally, but somehow became exposed only over time.
How do you find errors of omission with a static analysis tool? This is only one of salzer and schroeder's principles in action. What of the other 9? gem P.s. Five points to whoever names the principle in question. P.p.s.

I think I've also heard "a bug is small", a flaw is big", but that definition is awfully squishy. If the difference between a bug and a flaw is indeed one of intent, then I don't think it's a useful distinction. Intent rarely brings with it other dependable characteristics. I've also heard "bugs are things that a static analysis tool can find", but I don't think that really captures it either. For example, it's easy for a static analysis tool to point out that the following Java statement implies that the program is using weak cryptography: SecretKey key = KeyGenerator.getInstance("DES").generateKey(); Brian _______________________________________________ Secure Coding mailing list (SC-L) SC-L@securecoding.org List information, subscriptions, etc - http://krvw.com/mailman/listinfo/sc-l List charter available at - http://www.securecoding.org/list/charter.php ---------------------------------------------------------------------------- This electronic message transmission contains information that may be confidential or privileged.
