Guarding the Castle Keep: Teaching with the Fortress Metaphor
- D. Frincke and M. Bishop, “Guarding the Castle Keep: Teaching with the Fortress Metaphor,” IEEE Security & Privacy Magazine 2(3) pp. 69–72 (May 2004).
AbstractThe computer security field is replete with metaphors—the original and most commonly used metaphor is the computer (or network) as a fortress, the walls of which must be guarded against potential breaches. This metaphor is useful, but like all metaphors, it is not precise. Understanding the differences, between the metaphor of a fortress and the realities of securing a system is crucial to students understanding the subtleties of computer security. We discuss the fortress metaphor as a pedagogical tool, both how it succeeds and how it fails to aid student understanding.
