This view organizes attack patterns hierarchically based on mechanisms that are frequently employed when exploiting a vulnerability. The categories that are members of this view represent the different techniques used to attack a system. They do not, however, represent the consequences or goals of the attacks. There exists the potential for some attack patterns to align with more than one category depending on one’s perspective. To counter this, emphasis was placed such that attack patterns as presented within each category use a technique not sometimes, but without exception.
