Claim:
1. A data processing method comprising: using a security gateway, filtering application level data units by routing network traffic through a plurality of scanning modules in a sequence; using a scanner history tracker, computing a block rate for each module by tracking, over a period, which units are received by each module in a set of scanning modules and not forwarded toward a destination specified in those units; using a scanner driver, automatically re-ordering the sequence in which units are scanned by the scanning modules based on the block rate to preserve bandwidth of the security gateway by dynamically placing a module with a highest ratio of block rate to run-time cost before other modules in the set of scanning modules such that a most effective scanning module blocks data units before scanning is wasted on those data units by other modules; wherein the data processing method is performed by one or more computing devices.
