Abstract:
1. An apparatus comprising: an event handling device to receive network traffic and to forward the network traffic towards a destination endpoint when the network traffic conforms to one or more rules in an access list, wherein the one or more rules comprise at least one main rule configured to reference one or more extended rules that further define one or more attributes of the at least one main rule, and wherein the event handling device is configured to generate one or more log entries responsive to an application of one or more of the main rule and at least one of the extended rules to the network traffic when determining whether to allow the network traffic to pass towards the destination endpoint; an event log, communicatively coupled to the event handling device, wherein the event log is configured to store the one or more log entries generated by the event handling device; and a value generator to generate a first unique hash value of one specific extended rule which prompted the event handling device to generate a corresponding log entry, generate a second unique hash value of one specific main rule in the access list from which the specific extended rule was derived and append the first and second hash values to the one or more log entries.
