Description
Technical Field
The invention discloses a business portrayal and anomaly monitoring system and method based on multidimensional data, and belongs to the technical field of data anomaly monitoring.
Background
With the development of network technology, network services are increasingly abundant and various, and network traffic data are increasingly complex. The traditional network management mode can not meet the requirements of rapid and accurate identification and intelligent management of network service behavior characteristics.
The existing network technologies mainly have several types:
(1) Network device management techniques. And managing and monitoring the network equipment through network traffic and SNMP network management protocol to acquire data such as state, performance and the like of the network equipment.
(2) Network security analysis techniques. And comparing the network traffic data with a virus library or an attack library by acquiring the network traffic data, so as to acquire whether the network traffic data is an attack behavior or a virus transmission behavior or not, and then blocking.
(3) Server agent software monitoring techniques. And acquiring the service running state, service flow delay and other contents on the server through the server installation agent. Or network management software is connected with network equipment through SNMP protocol to check port state of the network equipment and condition of internal LAN link connected with the switch.
To sum up, the prior art has the technical problem that can't be solved:
(1) The data dimension is single: the prior art mainly focuses on single dimension of network traffic, such as traffic size, transmission speed, etc., while ignoring data of other dimensions, such as source IP, target IP, ports, etc., so that comprehensive and accurate analysis of user behaviors is limited.
(2) The accuracy of the data conclusion is not enough: the prior art only analyzes a small amount of or single data indexes, the indexes can only reflect the current data at a certain time point, and the false alarm rate of the analysis result is higher due to the interference of other factors of the network data.
(3) The service and the service operation index cannot be determined: the existing network management technology and network security analysis technology only use a small amount or single data analysis result for network management or security attack detection, and cannot identify different information services and service behaviors.
(4) The full chain state of service access cannot be identified: the existing server agent technology only reflects the service operation condition of the server end and fails to reflect the actual service operation condition of the client end. Aiming at the network management software technology, the network condition reaction of the local area network is limited, and the operation condition of the service cannot be truly reflected. And the prior art cannot accurately reflect the situation that the service from the client to the server runs the full chain and the nodes on the chain.
(5) Lack of active analog user access technology: the prior art lacks active simulation capability for user behaviors, and can not predict and simulate the user behaviors, so that a network administrator can not know the actual use state of a user, and can not discover and solve the network problem in advance.
(6) Cannot be monitored and pre-warned in real time: the prior art cannot monitor network traffic in real time and send out early warning, so that an administrator cannot discover and process network problems in time, and network faults or service interruption can be caused.
Thus, the prior art pairs: the service image is obtained through the multidimensional data, and the service requirements of anomaly monitoring are continuously displayed, so that how to track the whole service access process from the user side by taking the service access process as a view angle, and the real feedback of the perception of the service operation condition by the user side becomes the technical problem to be solved urgently in the technical field.
