Unlocking the Door to Better Cybersecurity

摘要

In their perspective ("reflections on cybersecurity," 13 November 2009, p. 943), W. A. Wulf and A. K. Jones claim that the perimeter defense model does not work. I agree with them that a perimeter has limitations. However, just as a lock on a front door is useful even though it can be broken, perimeters provide good, albeit imperfect, protection.
