firewall code
|
|
|
|
n. 1. The code you put in a system (say, a telephone switch) to make sure
|
|
that the users can't do any damage. Since users always want to be able to do
|
|
everything but never want to suffer for any mistakes, the construction of a
|
|
firewall is a question not only of defensive coding but also of interface
|
|
presentation, so that users don't even get curious about those corners of a
|
|
system where they can burn themselves. 2. Any sanity check inserted to catch
|
|
a can't happen error. Wise programmers often change code to fix a bug twice:
|
|
once to fix the bug, and once to insert a firewall which would have arrested
|
|
the bug before it did quite as much damage.
