Description
Technical field
The present invention relates to network security to monitor field, is based especially on the APT monitoring defence methods of big data analysis.
Background technology
Under the overall background of global network level of informatization high speed development, possesses disguised, permeability and targetedly high
Level continuation threatens（APT, advanced persistent threat）The prestige to caused by all kinds of high-grade information safety systems
Coerce getting worse, for specific objective organized APT attack it is increasing country, enterprise network information system and
Data safety faces a severe challenge.For example, China Great Wall network in 2008 suffers from the attack infiltration of U.S. Department of Defense's network hacker,
It is implanted back door and steals information；" the shake net " of 2010.
By preparation for many years and latent, successful attack is located at the industrial control system in physical isolation Intranet, sluggish
The nuclear programme of Iran；" the night dragon action " of 2011 has stolen the extremely sensitive internal text of multiple transnational energy giant companies
Part；The supervirus " flame " of 2012 successfully obtains the substantial amounts of confidential information in Middle East various countries.As can be seen that APT attacks are
Through all kinds of key message infrastructure securities are caused with grave danger, it is very urgent to carry out the work of APT attack defendings.APT is attacked
Hit in defense work, attack detecting be security protection and reinforce premise and foundation, and in APT attack defendings it is most difficult
Part, therefore detection technique has turned into the study hotspot in current APT attack defendings field.However, from the point of view of typical case,
APT attacks have extremely strong hidden ability and specific aim, and traditional detection device is felt simply helpless mostly in face of APT attacks.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide the APT analyzed based on big data to monitor defender
Method, the defence attacked APT in monitored area is realized, effectively prevents APT attack.
The purpose of the present invention is achieved through the following technical solutions：A kind of APT monitorings based on big data analysis are anti-
Imperial method, comprises the following steps：
S1 carries out network hierarchy division to collecting zone：Collecting zone is divided into Back ground Information network and important information system；
S2 collects the data of each collecting zone：Receipt in collecting zone is collected including data on flows and database
Protocol data；
The information being collected into make a distinction by feature by S3；
S4 is clustered the information being collected into, and realizes the dynamic sensing to security incident, and note abnormalities rule, pre- so as to produce
Alert information；
S5 is presented to analysis result.
Further limit, it is described network hierarchy division is carried out to collecting zone to be specifically divided into Back ground Information network and important
Information system.
Further limit, described Back ground Information network is the network of individual consumer.
Further limit, described important information system is in the webmaster of concentration network of medical treatment, bank, electric power and property
The heart.
Further limit, the data of the described each collecting zone of collection include step in detail below：
Collector is installed in collecting zone by S21；
S22 completes host log all in collecting zone using main frame probe；
S23 utilizes the mail in network probe completion one's respective area, social platform data on flows, database manipulation data, long-range control
Data processed and networks congestion control data；
S24 detects the plant maintenance information of collecting zone using collector, and realizes collecting zone and front end data acquisition platform
Communication.
Further limit, it is described by the information being collected into carry out by feature make a distinction including：
Establish mail features storehouse and the e-mail messages being collected into are subjected to feature extraction, especially to including link in text and with attached
The mail of part carries out depth analysis；
Establish the social platform information that social platform feature database is collected into and carry out feature extraction to information in station with link
Hold and carry out depth analysis；
Behavioural characteristic storehouse is established from individual Internet Access behavioral data analysis inside under fire organization, identifies possible spear type
Phishing attack, spoof attack.
Establish intranet data stream feature database and carry out data flow white list modeling.
Further limit, it is described by the information being collected into carry out cluster make to belong to same category of individual between distance use up
May it is small, and it is different classes of on individual between distance it is as big as possible.
Further limit, it is described that analysis result is presented, to generate all kinds of forms and analysis report.
The beneficial effects of the invention are as follows：Present invention employs the splicing of the packet of session-oriented, application program network service
Session legitimacy detection, to network service process carry out filtering block have information flow detection with alarm, operating process supervision with
Audit, data convert are with recovering the multiple functions such as support.Lifted, had obvious to improving domestic the overall of evidence obtaining product technology
Impetus.
Brief description of the drawings
Fig. 1 is the inventive method flow chart.
Embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
As shown in figure 1, the APT based on big data analysis monitors defence method, comprise the following steps：
S1 carries out network hierarchy division to collecting zone：Collecting zone is divided into Back ground Information network and important information system；
The described network hierarchy division that carried out to collecting zone is specifically divided into Back ground Information network and important information system.
Described Back ground Information network is the network of individual consumer.
Described important information system is the network management center of the concentration network of medical treatment, bank, electric power and property.
S2 collects the data of each collecting zone, and the receipt in collecting zone is collected including data on flows and data
The protocol data in storehouse, it is specially：
Collector is installed in collecting zone by S21；
S22 completes host log all in collecting zone using main frame probe；
