Background technology
Along with network application is more and more; Also when the river rises the boat goes up for the demand of bandwidth; Proposed challenge for thus the actual solution of software and hardware of security audit, how at any sacrifice in performance not or the security audit of paying realization enterprise application on the basis of less performance cost for becoming emphasis of design.
The technology of depth detection mainly is that the technology of application state detection fire compartment wall is closed with the technology of application layer traffic-the identification mutually; Identify the various application on the network efficiently; And through thereby the detection of using flow data is realized other security audit of network application level; Flow control, the security strategy of enterprise-level application is implemented, the functional requirement of high reliability etc.The practical solution of depth detection technology runs into the challenge of many realizations, such as the encryption of application program, tunneling technique.
It is more and more wide in range that the security gateway series products is used, and expands to UTM, IPS, online flow analysis watch-dog, online flow management apparatus, web Access Management Access equipment or the like from the fire compartment wall of classics.These use existing powerful abundant message analysis and flow analysis function; Also need transmit processing efficiently to flow through this equipment; General character from the security gateway series products; Though their application scenarioss are different, all need powerful CPU disposal ability and come to guarantee simultaneously analytical work and forwarding work, and the restriction of CPU disposal ability often make forwarding work tie up the required resource of analytical work; The product application developer expensive energy on the balance choice problem of performance and function of having to, network performance problems even become the restriction function further to enrich perfect bottleneck.
Look back typical security gateway application software and realize having following 'bottleneck' restrictions network performance and promote based on the X86 system:
(1) bus;
(2) interrupt;
(3) message conversion and checking treatment;
(4) routing table, status table;
(5) traffic classification algorithm;
(6) traffic sampling, statistics and scheduling.
To these problems; Technology such as ASIC chip, network processing unit, polycaryon processor occur in succession; And from the solution more or less of different aspect different angles the problems referred to above; Yet, to compare with very fast lifting, the abundant very fast demand growth speed of business function of network performance, these frameworks are not popularized fast; To still there being no small leap distance the application product of maturation, this distance has restricted above-mentioned proprietary hardware structure popular and universal in the security gateway field from outstanding chip ability.
Summary of the invention
The present invention adopts intelligent ten thousand Broadcom multi-core platforms; Subpackage and assembling with packet; The identification of basic agreement and application protocol is handled, and compression, decompression are encrypted; The shunting of functions such as deciphering is handled by the multi-core platform of intelligent network adapter; And the processing of the audit operations flow process PCI-EXPRESS bus through high bandwidth is diverted to X86 CPU platform processes, such solution integration system resource in the short period of time satisfies user's bandwidth control, the functional requirement of basic security strategy control of using etc.
In order to achieve the above object, the present invention has designed a kind of superelevation broadband network method for auditing safely based on the intelligent network adapter multi-core platform, it is characterized in that adopting following steps:
A. dispose the intelligent network adapter multi-core platform: comprise DPI engine configuration, the setting of filtration set of keywords, application protocol configuration, encrypting and decrypting setting, compression algorithm configuration;
B. the intelligent network adapter multi-core platform receives and handles original message: through PCI allocation-EXPRESS bus transfer; The intelligent network adapter multi-core platform is handled the primitive network data message, and the application data after will handling is via the CPU platform of PCI-EXPRESS bus transfer to X86;
C. the depth detection of application data and audit: application data carries out auditing after the depth detection, the BPM interface configurations of the CPU platform through X86;
D. the subsequent treatment after auditing: the auditing result according to application data is carried out subsequent treatment.
In step C, the depth detection of said application data mainly comprises pattern feature identification, user behavior analysis, dynamic application identification.
In step C, the audit of said application data mainly comprises flow control, security control.
In step D, described subsequent treatment mainly comprises the transmission alert message, and restriction or blocking-up data flow generate statistical report form.
The present invention adopts the intelligent network adapter multi-core platform, for multiple business fields such as network security, flow monitoring, business diagnosis, signaling detection provide effective speeding scheme, can be applied in the superelevation bandwidth of 100G; Adopt the mode of shunting operation flow simultaneously, application strategy safety, good reliability adopt the depth detection technology simultaneously, thereby realize the functional requirement to the security strategy enforcement of other security audit of network application level, flow control, enterprise-level application etc.
