A method comprising: a host system identifying anti-pass back enabled access controllers in a facility supported by the host system; the host system identifying anti-pass back enabled card readers supported by the anti-pass back enabled access controllers; the host system identifying a respective form of anti-pass back feature used by each of the anti-pass back enabled access controllers, wherein the respective form is one of GLOBAL, SITE, and AREA; the host system identifying valid card transactions occurring on each of the anti-pass back enabled card readers within a predetermined time period; the host system determining a total number of anti-pass back status messages generated by the host system in connection with the host system monitoring the facility over the predetermined time period by totaling a respective number of the anti-pass back messages generated by the host system for each of the anti-pass back enabled controllers in response to the valid card transactions occurring during the predetermined time period, wherein the respective number of the anti-pass back status messages generated by the host system for each of the anti-pass back controllers in response to the valid card transactions occurring during the predetermined time period is calculated using GLOBAL based anti-pass back calculations for the anti-pass back enabled access controllers identified as GLOBAL, SITE based anti-pass back calculations for the anti-pass back enabled access controllers identified as SITE, and AREA based anti-pass back calculations for the anti-pass back enabled access controllers identified as AREA; the host system comparing the total number of the anti-pass back status messages generated by the host system with a baseline threshold value; when the total number of the anti-pass back status messages generated by the host system is less than or equal to the baseline threshold, the host system determining that enabling the anti-pass back feature in the facility will be successful; and when the total number of the anti-pass back status messages generated by the host system is greater than the baseline threshold, the host system determining that enabling the anti-pass back feature in the facility will fail. a host system identifying anti-pass back enabled access controllers in a facility supported by the host system; the host system identifying anti-pass back enabled card readers supported by the anti-pass back enabled access controllers; the host system identifying a respective form of anti-pass back feature used by each of the anti-pass back enabled access controllers, wherein the respective form is one of GLOBAL, SITE, and AREA; the host system identifying valid card transactions occurring on each of the anti-pass back enabled card readers within a predetermined time period; the host system determining a total number of anti-pass back status messages generated by the host system in connection with the host system monitoring the facility over the predetermined time period by totaling a respective number of the anti-pass back messages generated by the host system for each of the anti-pass back enabled controllers in response to the valid card transactions occurring during the predetermined time period, wherein the respective number of the anti-pass back status messages generated by the host system for each of the anti-pass back controllers in response to the valid card transactions occurring during the predetermined time period is calculated using GLOBAL based anti-pass back calculations for the anti-pass back enabled access controllers identified as GLOBAL, SITE based anti-pass back calculations for the anti-pass back enabled access controllers identified as SITE, and AREA based anti-pass back calculations for the anti-pass back enabled access controllers identified as AREA; the host system comparing the total number of the anti-pass back status messages generated by the host system with a baseline threshold value; when the total number of the anti-pass back status messages generated by the host system is less than or equal to the baseline threshold, the host system determining that enabling the anti-pass back feature in the facility will be successful; and when the total number of the anti-pass back status messages generated by the host system is greater than the baseline threshold, the host system determining that enabling the anti-pass back feature in the facility will fail.
