The present invention discloses a distributed network security system. At least one probe unit is distributed in links before at least one end-node within a network, the probe units are adapted to provide a plurality of network securities and/or management means for the network and a plurality of management units couples to the network, the plurality of management units are adapted to manage the probe units, wherein the plurality of management units includes a central master unit and a plurality of boss units. The plurality of network and management measures can be directly applied to specific end-nodes, such as communication policing, content filtering and monitoring. These probe units are configured through a central master unit and each of the probe units may have different configurations according to the demand of network administrators. Information collected by the probe units are transferred back to the central master unit and/or boss units for further analysis to provide network administrators valuable information that supports to manage the network. Additionally, one or more management units with lower priority than the central master unit are adapted to manage a predetermined group of the probe units such that a plurality of different groups of probe units are possible to coexist and managed in the network.
