1. A method for processing an event having a classification based on associated policy rules, the policy rules being conditioned on the classification, the method comprising the steps of:

  • providing a policy rules hash table including a plurality of policy rule entries, each policy rule entry being associated with a hash index;

    receiving the event;

    generating a hash index using a classification hash length based on the classification of the event, the classification having an associated length at least equal to the classification hash length;

    identifying a policy rule entry in the policy rules hash table that corresponds to the generated hash index;

    determining if a classification field length associated with the identified policy rule corresponds to the classification hash length; and

    executing the identified policy rule entry if the hash length associated with the identified policy rule corresponds to the classification hash length.
