Description of the drawings
The attached drawing for constituting the part of the present invention is used to provide further understanding of the present invention, schematic reality of the invention
Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings：
Fig. 1 is the flow chart of the method according to the present invention for preventing scanning authority；
Fig. 2 is the module map of the system according to the present invention for preventing scanning authority.
Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.It needs
Illustrate, in the absence of conflict, the features in the embodiments and the embodiments of the present application mutually can be combined arbitrarily.
The present invention provides a kind of methods preventing scanning authority, as shown in Figure 1, this method includes：
Step 101, after node server receives client for the request of the authority of a domain name, judge that domain name is
It is no to be present in the white list or blacklist to prestore；
Step 102, if judging, domain name is not present in the white list to prestore or blacklist, is sentenced based on default judgment rule
The disconnected request is normal behaviour, scanning behavior or unknown behavior, if normal behaviour or unknown behavior, is then sent to client
The default privilege file being generated in advance then is refused to ask if scanning behavior.
Here default judgment rule is stored in advance on node server, can be issued by central server
It arrives, can also issue to obtain by other servers, header information feature and corresponding normal behaviour or is swept in request message
The attribute of behavior is retouched, can judge that the header information in the request message is still swept for normal behaviour according to the header information feature
Retouch behavior.
It should be noted that here when judging the request for unknown behavior, default privilege file still is sent to client,
It is in order to ensure the response speed to client, in order to avoid due to directly refusing or influencing to service without response for a long time.
In step 101, if judging, domain name is present in the white list, is generated in advance to client transmission
Default privilege file；If judging, domain name is present in the blacklist, refuses the request.
When node server is run, white and black list can be loaded into the memory of server, to improve response speed.
If domain name in white list, returns to default privilege file, which is adopted by node server based on service conditions
It is generated according to known condition with certain strategy, the phase of the prior art can be referred to inside the Pass about generating for default privilege file
Hold, details are not described herein.If domain name in blacklist, refuses the request, such as returns to the initial data of source station response
(4XX, 5XX conditional code).
Step 101 further include upon receiving the request, and judging domain name whether there is in the white name
It is executed before the single or described blacklist：Judge whether there is the authority on the node server, by the power if having
Limit file is sent to the client, if not having, inquires whether the source station of domain name has the authority, if so, then
Obtain the authority from the source station and be sent to the client, if not having, judge domain name whether there is in
In the white list or blacklist that prestore.
Node server judges locally whether have the authority after receiving client to the request of authority
Caching go back to source station if not if any client is then transmitted directly to and pull the authority.If there is the authority in source station
Then directly give, if without if can corresponding 4XX, 5XX conditional code, and judge that the domain name whether there is in white name by node server
In list or blacklist.
Here, it if there are such cache file on node server, turns out and the request of the domain name was verified
For normal behaviour, therefore can directly transmit.In addition, if source station there are this authority, is considered as the presence of this website
The business of access right file, and be to carry out certain precautionary measures.Given this upper 2 points, can judge the domain name it
Preceding elder generation locally carries out judging and first attempt to obtain authority from source station in node server.
In a step 102, if judging the request for unknown behavior, the default privilege is being sent to the client
After file, the request relevant information is sent to central server；The central server is based on the request relevant information
Judge the request for normal behaviour, scanning behavior.
If node server judges the request for unknown behavior, i.e., it can not determine that the request is normal behaviour or scan line
Then to need to make a concrete analysis of the request by central server, to judge that the request still scans behavior as normal behaviour.
What central server was sent based on node server here is judged with the relevant information of the request.These request relevant informations
It may, for example, be request message.By the judgement of the step, which can be determined as to normal behaviour or scanning behavior,
To supplement new content for behavior judgment rule, and the unknown associated domain name of behavior is added into blacklist or white list
In.
Further, central server judges the request for normal behaviour, scan line based on the request relevant information
It is to include：
The header information of the request is obtained based on the request relevant information；
The request is judged for normal behaviour based on the header information or scans behavior, if being judged as normal behaviour,
The corresponding domain name of request is added in white list, if being judged as scanning behavior, the corresponding domain name of request is added
In blacklist；
The white list and the blacklist are issued to node server.
Here behavioural analysis operation is realized that data analysis system can be located at central server by data analysis system
On, can also be on other servers as described above.When data analysis system is located on other servers,
Then relevant information will be asked to be sent to data analysis system by central server to analyze, then be divided from data by central server
Analysis system obtains analysis and obtains as a result, updating black and white lists in addition, and carry out updated black and white lists to each node server
Issue.
The monitoring software of central server can monitor special interface, data of the Asynchronous Reception from the whole network node server.
In addition, central server determines black and white lists data and unknown domain name, the domain name for having determined as black and white lists is added to black
In white list, and newer black and white lists are synchronized and are issued to each node server, when locally judging so as to each node server
It uses.
Therefore, the effect of central server is as follows：
(1) by the data summarization of distributed type assemblies, so that data analysis system is further analyzed；
(2) by internal information pipeline, black and white lists is issued to grade of each node server second, the whole network Fast synchronization is solved and asks
Topic；
(3) the analysis data result of data analysis system, such as black and white lists are obtained, behavior judgment rule is scanned, by it
It is issued to the node server of the whole network.
The analytic process of the data analysis system is described below in detail：
(a) after data analysis system receives the header information of the request, website known to Baidu, 360 etc. is established for should
The security sweep task of the corresponding domain name of request, to obtain the head feature of such scan task, and by the head
Feature is added in header information property data base.
(b) the unknown domain name data and safe business men scanning behavioral data that central server is sent are received, because being above
The security sweep task of website known to Baidu, 360 etc. is established, but there is likely to be the scanning of unknown or obscure business men, examples
Such as Topsec, deeply convinced, it is therefore desirable to the scanning behavioral data of other safe business mens, the i.e. head feature of scan task are obtained,
And these head features are added in header information property data base.
(c) message data will be made requests on to arrange, unknown domain name data and scan data will be excluded by screening washer
The header information judged is cannot act as, such as：Host (domain name of request), client-ip (client ip) etc.；Exclusion has been acknowledged
Know the head of rule, is such as judged, referer by referer (header information for indicating request source):Xxx.swf is indicated
The request comes from swf players website, such as http://www.cutv.com/demo/live_test.swf.
(d) it is left above-mentioned after exclusion cannot act as the header information judged and have been acknowledged the head for knowing rule
Information by contrast device, i.e., with the header information Characteristic Contrast in header information property data base, judge the request be scanning
Behavior or normal behaviour, and correspondingly the corresponding domain name of the request is added in blacklist or white list.
(e) updated blacklist and white list and header information property data base are exported.
This method further includes being executed before step 102：Generate the default privilege file.
It is described below in detail according to a particular embodiment of the invention, which includes the following steps：
Step 1, node server receive the request of the authority for a domain name www.123.com, judge local
Whether the caching of the authority is had, if so, being then sent directly to send out the client of request, if it is not, inquiry source
Whether have the authority, obtain the authority from source station if source station has and be sent to client, if source station does not have if standing
There is 4XX, 5XX conditional code then received from source station, and executes next step.
Step 2, by domain namewww.123.comIt is compared, judges with the white and black list of node server storage
The domain name whether there is in white list or blacklist, if being present in white list, returns and is generated in advance according to known condition
Default privilege file 4XX, 5XX conditional code for being received from source station is returned to, if being not present in white if being present in blacklist
In list and blacklist, then next step is executed.
Step 3, it is normal that the default rule of conduct stored according to node server, which judges that this is directed to the request of authority,
Behavior, scanning behavior or unknown behavior, if normal behaviour, then to client transmission default privilege file, and by the domain name
It is added in white list and updated white list is synchronized to central server, then will be updated white by central server
List is issued to each node server；If scanning behavior, then 4XX, 5XX conditional code received from source station is returned to, by the domain name
It is added in blacklist and updated blacklist is synchronized to central server, then will be updated black by central server
Name single pass-through internal information pipeline is issued to each node server；If unknown behavior, then default privilege file is equally returned to, and
Execute next step.
Step 4 will be sent to central server with the relevant information of the request.
Step 5, central server extracts the header information of the request from the request relevant information, by header information
Compared with the head feature database of the known scanning behavior of storage pair, if the head that the header information is with one scan line
Feature is consistent, it is determined that the request is scanning behavior, which is added in blacklist, if inconsistent, it is determined that
The request is normal behaviour, which is added in white list, and is believed the head in the request message of the unknown behavior
Breath is added in head feature database.
Updated white and black list and head feature database are passed through inside by step 6, central server
Information conduit is issued to each node server.
