1. A method for dynamically scaling a confidence level of a detected attack on a computer system, the detected attack being detected by an intrusion management system in a communication with the computer system, the method comprising: (a) assigning an initial confidence level to the detected attack; (b) detecting, in the communication, at least one scalar selected from the group consisting of (i) a first scalar indicating packet loss in the communication, (ii) a second scalar indicating whether the intrusion management system has observed the communication from a beginning of the communication, and (iii) a third scalar indicating whether the communication includes any information not understood by the instrusion management system; and (c) scaling the initial confidence level in accordance with the at least one scalar detected in step (b) to provide a scaled confidence level.
