Categorizing Security

There is an immense literature on the analysis and categorization of security. Part of the reason for this is that, in most security systems, the "weakest link in the chain" is the most important. The situation is asymmetric since the 'defender' must cover all points of attack while the attacker need only identify a single weak point upon which to concentrate.

Famous quotes containing the word security:

    “It is hard for those who have never known persecution,
    And who have never known a Christian,
    To believe these tales of Christian persecution.
    It is hard for those who live near a Bank
    To doubt the security of their money.”
    —T.S. (Thomas Stearns)
