Abstract: Systems and methods for increasing layer 2 visibility of layer 3 network devices so as to facilitate implementation of device-oriented policy actions by layer 3 network devices are provided. According to one embodiment, unique physical addresses of one or more host devices are retrieved by a dynamic host configuration protocol (DHCP) agent that is operatively coupled with a DHCP server. The physical addresses are mapped to corresponding Internet Protocol (IP) addresses assigned by the DHCP server to the one or more host devices. The mapping is relayed directly or indirectly to a network security device. Network traffic management/security policies are defined within the network security device corresponding to at least one of the unique physical addresses.

Abstract: Systems and methods for automated learning of externally defined network assets by a network security device are provided. According to one embodiment, updated information for a network asset associated with a private network is received by a network security device from an external asset management device associated with the private network. The updated information includes a change in a definition or an attribute of the network asset. The existence of a current definition and attribute information for the network asset is determined by the network security device. The current definition and attribute information is dynamically updated based on the updated information by the network security system within a run-time representation of security policy rules within a kernel of a network security operating system without disrupting on-going application of one or more security policy rules defined for the network asset to network traffic directed to or originated by the network asset.

Abstract: Methods and systems for extracting, processing, displaying, and analyzing events that are associated with one or more threats are provided. According to one embodiment, threat information, including information from one or more of firewall logs and historical threat logs, is maintained in a database. Information regarding threat filtering parameters is received. Information regarding threats matching the threat filtering parameters are extracted from the database and is presented in a form of an interactive historical graph. Responsive to receiving from an administrator an indication regarding a selected subset of time in which to zoom into for further details, a list of threats within the selected subset is presented in tabular form.

According to one embodiment, threat information, including information from one or more of firewall logs and historical threat logs, is maintained in a database. Information regarding threat filtering parameters, including one or more of types of threats to be extracted from the database, parameters of the threats, network-level details of the threats, a time interval of detection of the threats and source-destination details of the threats, is received. Information regarding threats matching the threat filtering parameters are extracted from the database and is presented in a form of an interactive historical graph. Responsive to receiving from a user an indication regarding a selected subset of time in which to zoom into for further details, a list of threats within the selected subset is presented in tabular form.
