Show lamp.Such as：It is normal that power lights can be shown as power work by green, and red display power work is abnormal.
In the present embodiment, network security monitoring device uses active and standby dual power supply.
Network security monitoring device uses active and standby dual power supply.Primary power cource is powered under normal circumstances, works as primary power cource
It when abnormal, is powered by stand-by power supply, to guarantee network security, monitoring device at any time being capable of normal operation work.
In the present embodiment, case front panel is equipped with operation and controls mouth and the electricity such as serial ports, management mouth, data port, USB port
The indicator lights such as source lamp, running indicator are equipped with 220V power interfaces and power switch after cabinet.
In the present embodiment, the serial ports is RS232 serial ports；The management mouth and the data port are RJ-45 mouthfuls；Institute
It is standard USB interface to state USB port mouth.
RS232 is PC machine and most widely used a kind of serial line interface in communication industry at present.RS232 is defined as one kind
Increase the single-ended standard of communication distance in low rate serial communication.RS232 takes uneven transmission mode, i.e., so-called single-ended logical
News.Its transmitting range is up to about 15 meters, flank speed 20kb/s.RS232 designs for point-to- point communication, driving
Device load is 3~7k Ω.So RS232 is suitble to the communication between local device.RS-232 serial rates.
RJ-45 is one kind of telecommunications outlet in wiring system (communicating exit) connector, and connector (is connect by plug
Head, crystal head) and socket (module) form, plug has 8 grooves and 8 contacts.RJ is the abbreviation of Registered Jack,
It means " socket of registration ".RJ is description public telecommunication network in FCC (Federal Communications Commission standard and regulations)
Interface, the RJ45 of computer network is being commonly called as 8 modular interfaces of standard.RJ45 is made of plug and socket, both
The connector of component composition is connected between conducting wire, to realize the electrical continuity of conducting wire.The core of RJ45 modules is module
Change jack.Gold-plated conducting wire or socket aperture can maintain to stablize and reliable electric appliance connection between modular socket shrapnel.Due to
Rubbing action between shrapnel and jack, electrical contact are further strengthened with the insertion of plug.Jack body design uses
Integral locking mechanism can generate maximum pull strength in this way when modular plug is inserted into outside the interface of plug and jack.
Wiring module in RJ45 modules connects twisted-pair feeder by " u "-shaped connecting groove, and locking spring plate can be in information outlets such as panels
RJ45 modules are fixed on device.RJ45 connector is often used a kind of anti-skidding plug boot, for the company's of protection plug, anti-slip and be convenient for
Plug.
USB (Universal Serial Bus), i.e. universal serial bus, it is an external bus standard, for advising
Model computer and external equipment are connected and communicate with.It is a kind of interface being widely used in the fields PC.
In the present embodiment, the hard disk is electronic hard disc.
In the present embodiment, the rack of network security monitoring device is 19 inch standard racks；It is arranged in the rack
Cabinet height is 2U.The rack and cabinet of above-mentioned dimensions are that a kind of most common dimensions in other embodiments can
To choose other sizes.
The length dimension of 19 inch standard racks is 19 inches, i.e. 482.6mm.The cabinet height being arranged in rack is 2U.
1U is 1.75 inches, i.e. 44.45mm, refers to highly just cabinet that panel height is 88.9mm for the cabinet of 2U.
Interface subcard 10, service processing board 12 are electrical connected by PCIe buses and backboard 11.
PCIe (PCI-express) is a kind of general bus specification, it is advocated and promoted by Intel, final
Purpose of design is gone out to solve data transmission in present-day systems to replace the bus transfer interface inside existing computer system
Existing bottleneck problem, and prepare for following peripheral product performance boost.The various equipment of previous computer system share
One bandwidth, using parallel interconnection, this leverages the performance of system entirety, while parallel signal is due to interfering with each other
Also the further promotion of speed in the future is seriously constrained.And PCIe then uses serial interconnection mode, in the form of point-to-point into
Row data transmission, each equipment can individually enjoy bandwidth, to substantially increase transmission rate, and be higher
Frequency upgrading creates condition.
Meanwhile PCIe, also there are many interface modes of friction speed, this includes 1X, 2X, 4X, 8X, 16X and higher speed
32X.The transmission rate of PCIe 1X patterns can reach 250MB/S, close to two times of original pci interface 133MB/S, greatly
The big data transmission capabilities for improving system bus.
This is applied to the network security monitoring device of LAN when in use, first connects 220V AC powers to network security
Monitoring device component is powered, and equipment enters init state, is read in Software Mirroring to SDRAM memory from hard disk, then
It jumps in mirror image and proceeds by initialization.After equipment start completion, into normal operating conditions.By interface subcard, by net
Network flow introduces equipment, and flow is first uploaded to service processing board by interface subcard, is handled by the software on service processing board single
Member analyzes network flow, extracts attack information that may be present, forms daily record, by managing mouth or data port,
Daily record is uploaded into log server.
User can be directed to network flow actual conditions, the various assistant analysis provided using equipment when using equipment
Mode, voluntarily configuration rule, is extracted for realizing attack detecting and sensitive information.Regular description language supports IP five-tuples (i.e.
Source IP address, source port, purpose IP address, destination interface and transport layer protocol), message protocol number, message content etc. can be directed to
Single message carries out detailed analysis, while regular description language also supports various forms of counting rates, has certain DDoS anti-
Imperial ability.
