Methods and systems for managing security in a network

Methods, systems and computer readable mediums storing computer executable programs for managing security in a network are disclosed. A plurality of security policies associated with a plurality of network data anomalies are provided at a network management system. Each one of the plurality of security policies defines a network data anomaly specific mitigation response for each one of the plurality of network data anomalies. A first network data anomaly is detected at the network management system. A determination is made at the network management system regarding whether a first one of the plurality of security policies defines a first network data anomaly specific mitigation response to the first network data anomaly. A first mitigation command is issued from the network management system to at least one network system to implement the first network data anomaly specific mitigation response for a pre-defined period of time in accordance with the first security policy based on the determination.
