Embodiment Construction

[0030] Figure 2 depicts a block diagram of a logging device according to an exemplary, non-limiting embodiment of the present invention. The log device shown in FIG. 2 includes: a firewall module 21 and a storage device 22 . The two modules are connected by one or more Gigabit Ethernet connectors. For simplicity and clarity, only one Gigabit Ethernet connector is shown in Figure 2 . In addition, the logging device may further include a display unit (as shown in FIG. 5 and described in more detail below). The display unit may be provided in a panel of the logging device. Alternatively, the logging device can be connected to a monitor for displaying the data to the user. This logging device with logging and analysis functions can be integrated with switches, gateways or routers.

[0031] As shown in FIG. 2 , incoming data, data flowing in from the Internet (Internet) 20 , encounters a firewall 21 . Firewall 21 may be provided on a separate circuit board or be provided on a ...

Abstract

A logging device, system and a method for managing network packets. The logging device includes a traffic capturing device receiving the network packets and filtering the network packets by selecting some of the network packets based on a predefined criteria. The logging device also includes a storage device storing the selected network packets and an analyzing component organizing the stored network packets in accordance with a user specified parameters. The traffic capturing component, the storage component, and the analyzing component are integrated in a single physical device providing a user with an ability to monitor real-time network traffic on the fly. The traffic capturing component selects the network packets for storage based on source and destination addresses of the network packets, based on a protocol of the network packets, based on a port designated, and based on whether a particular traffic session matches a predetermined signature.

Description

technical field [0001] The invention relates to a method, system and device for network flow log recording and analysis. Background technique [0002] Due to regulations, many companies require storage of network traffic for a certain period of time. For example, US 404 certification and the Insurance Portability and Accountability Act (HIPPA) require companies to preserve network traffic for five to seven years. Typically, companies follow government regulations and hire a service provider that uses network packet sniffer technology to collect network traffic. These flows are then stored in designated locations. Once the data is stored, various analysis devices classify the data, archive and mine the desired information from the data. Analyze these data packets one by one to extract the required information. [0003] On the technical side, network traffic conditions, data exchanges between clients and servers and between clients and clients can be seen in a device calle...
