Seeing Fig. 1, it is the application scenarios schematic diagram that application the embodiment of the present application updates URL storehouse.

Fig. 1 shows the group-network construction of typical commercial network (such as enterprise network).Wherein, user is eventually End is connected by safety equipment between outer net far-end server, and described safety equipment can be fire wall etc. Network Security Device, it addition, except PC (Personal Computer, individual as user terminal example Computer) outward, user terminal can also include that mobile phone, panel computer etc. have the equipment of network access functions. Safety equipment can carry out specification to the internet behavior of user terminal, and the most typical internet behavior is exactly Web access, this is the main business that major part safety equipment need to carry out safety service process.Safety equipment Maintain the URL storehouse of self, this URL storehouse is that safety equipment carry out the master of safe handling for web access Will foundation.In general URL storehouse can include URL white list, naturally it is also possible to include that URL is white simultaneously List and URL blacklist.URL white list represents that Web page pointed by which URL address is permissible Accessing, URL blacklist then represents that Web page pointed by which URL address is prohibited from access.

Owing to conventional safety apparatus URL storehouse often relies on the storehouse of third part purchase, it can only meet some and lead to Demand, but there is self individual demand in major part enterprise, it cannot meet in time.Namely Saying, for enterprise, URL storehouse renewal rate on individual demand is slowly, it is impossible to adapt to net The quick growth of number of pages, causes the URL address insufficient of storage in safety equipment URL storehouse, to such an extent as to works as Also can be blocked during the believable webpage of user terminal access Partial security.

For solving prior art problem, the application provides a kind of method updating URL storehouse and the device of correspondence. With reference to shown in Fig. 1, the method is applied on a security device.Safety equipment are mating less than webpage to be visited In the case of URL address, redirected by URL address and guide user terminal to submit described webpage to be visited to URL address is to management equipment, the method being carried out by artificial or Automatic Program auditing, thus is set by safety The standby examination result according to the URL address of the webpage to be visited of management equipment return updates URL storehouse.Typically For, management equipment is positioned in Intranet, and during such user terminal access management equipment, it accesses and is typically not Affined, such as the access for Intranet can be without safety equipment, even if in other words through also can Because being positioned at, URL white list is cleared.Certainly management equipment is likely to be positioned on the Internet, now may be used Management equipment to be added to website trusty, such as the URL of Web service will be provided on management equipment Address joins in safety equipment URL white list.

A kind of URL storehouse update method and the device that there is provided the application below in conjunction with the accompanying drawings illustrate.

See Fig. 2, for an embodiment flow chart of a kind of URL of the application storehouse update method, this embodiment It is described from safety equipment side, comprises the following steps:

Step 201: receive the HTTP request message that user terminal sends, described HTTP to far-end server Request message comprises the URL address of webpage to be visited.

Concrete, when Web page (also can be called for short " webpage ") on one the Internet of user terminal access, Can to provide this Web service far-end server send HTTP (Hypertext Transfer Protocol, HTTP) request message.Before described HTTP request message arrives far-end server, can be first Arrive safety equipment, and these safety equipment are usually located at the exit of enterprise network.Described HTTP request report With the URL address of user terminal webpage to be visited in literary composition.In general, HTTP request message is by asking Row, request header, null and request data 4 part composition, wherein, the URL of described webpage to be visited Address is present in the request row of HTTP request message.

Step 202: search the URL ground mated with the URL address of described webpage to be visited in URL storehouse Location.

Concrete, the URL storehouse of described safety equipment is configured with URL white list or URL white list adds URL blacklist, in described URL white list, storage has the URL address allowing user terminal access, and institute Stating operation corresponding after the URL address of webpage to be visited matches the URL address in this URL white list is Allowing to let pass, in described URL blacklist, storage has the URL address forbidding user terminal access, and described The URL address of webpage to be visited matches operation corresponding behind the URL address in this URL blacklist for prohibiting Stop-pass mistake.The HTTP request message of the described URL address with described webpage to be visited arrives safety equipment After, safety equipment search in this URL storehouse the URL ground mated the URL address with described webpage to be visited Location, if finding the URL address of coupling in URL white list, the most described HTTP request message is put Walk to far-end server；If finding the URL address of coupling in URL blacklist, then forbid this HTTP Request message passes through, to block the user terminal access to described webpage to be visited.

Step 203: if not finding the URL address of coupling, then guide this user terminal access to be positioned at appointment URL on management equipment gathers the page, in order to user terminal gathers the page by net to be visited by this URL The URL address of page is submitted to and is examined.

Concrete, one of them example, when the situation only having URL white list in the URL storehouse of safety equipment Under, and URL white list is searched less than the URL address mated with the URL address of described webpage to be visited, Then determine the URL address not finding coupling.In another example, when in the URL storehouse of safety equipment both In the case of having URL white list to have again URL blacklist, and in URL white list and URL blacklist all When searching less than the URL address mated with the URL address of described webpage to be visited, the most just can determine whether not look into Find the URL address of coupling.Either which example, when not finding the URL address of coupling, institute The WEB page of the URL address sensing stating webpage to be visited is temporarily considered dangerous incredible webpage, Therefore user terminal cannot immediately access this URL address.

In this case, the safety equipment of the application are by returning one HTTP redirection report of user terminal Literary composition, guides user terminal access to be positioned at and specifies the URL on management equipment to gather the page, and described HTTP resets The URL address of the page is gathered with this URL of sensing, so that user terminal is assisted according to HTTP in message The redirection mechanism of view automatically accesses this URL and gathers the page, and user can be manually by described webpage to be visited URL address is committed to manage equipment side by this URL collection page and examines.Step 204: according to pipe The examination result of the URL address of the page to be visited that reason equipment returns updates URL storehouse.

Concrete, if the examination result of management equipment side is for passing through, safety equipment then add described net to be visited The URL address of page is to URL white list；If the examination result of management equipment side is not for pass through, if URL Storehouse does not has URL blacklist, then forbids that the URL address of described webpage to be visited is passed through；If URL storehouse In have URL blacklist, then the URL address of webpage to be visited is added in URL blacklist by safety equipment, Thus realize the renewal to described URL storehouse.

Application above-described embodiment, safety equipment do not find and the URL of described webpage to be visited in URL storehouse During the URL address that address is mated, by the redirection mechanism of http protocol, user terminal access is guided to refer to URL on fixed tube reason equipment gathers the page, and gathers the page by described webpage to be visited according to this URL URL address is submitted to and is examined, thus safety equipment are according to the URL of the webpage to be visited of management equipment return The examination result of address updates URL storehouse, updates URL storehouse with the requirements for access realized according to user terminal, Thus meet the individual demand of enterprise self.

One idiographic flow block diagram of the embodiment of the present application is as shown in Figure 3:

Step 301: during user terminal access webpage, can be able to send with webpage to be visited to far-end server The HTTP request message of URL address, wherein, before described HTTP request message arrives far-end server Safety equipment can be first passed through.

Step 302: mate with the URL address of described webpage to be visited in safety equipment lookup URL storehouse URL address.

Concrete, general enterprises is joined in the consideration of secure context, generally the URL storehouse in safety equipment Putting URL white list, URL white list represents that Web page pointed by which URL address can access. In another preferred scheme, URL white list and URL blacklist, wherein, URL can be configured simultaneously Blacklist then represents that Web page pointed by which URL address is prohibited from access, so that safety equipment are more Perfect.

In described URL white list, storage has the URL address allowing user terminal access, and matches and treat Action type corresponding after accessing the URL address of webpage, the action type in URL white list is clearance； Wherein, URL white list can be stored in URL storehouse by the way of list item, as shown in table 1, and URL The list item example of white list is as follows:

Table 1 URL white list

Same, in described URL blacklist, storage has the URL address forbidding user terminal access, and Operation corresponding after matching the URL address of webpage to be visited, the action type in URL blacklist is resistance Disconnected, described URL blacklist can also be stored in URL storehouse by the way of list item, as shown in table 2, The list item example of URL blacklist is as follows:

Table 2 URL blacklist

In a preferred example, except forbidding that this HTTP request message passes through, safety equipment are all right Sending HTTP redirection message to user terminal, this HTTP redirection message carries sensing to be forbidden simultaneously Access the URL address of the prompting page.Browser on user terminal can be certainly after receiving HTTP redirection message Dynamic redirecting access this forbids accessing the prompting page, user can obtain one from this content of pages and prohibit clearly Only access and in prompting, such as this page, may have the forbidden reason of access.In another preferred example, This forbids including on the access prompting page that the URL address of the URL collection page (is equivalent to a Shen Tell link), user clicks on this link, can enter into URL and gather the page.URL gathers the effect of the page Follow-up further describe.

Step 303: if safety equipment do not find the URL address of coupling, then generate HTTP redirection report Literary composition, wherein, gathers the URL address of the page with URL in described HTTP redirection message.

Concrete, described HTTP redirection message belongs to http response message, by responsive trip, response Head and response body three part composition, wherein, described response head includes location field, described In location field, storage has URL to gather the URL address of the page.

Step 304: safety equipment transmission HTTP redirection message is to user terminal, and described HTTP is heavy Orientation message gathers the URL address of the page with URL.

Step 305: user terminal, according to the URL address in HTTP redirection message, generates with this The HTTP request message of URL address.

Step 306: user terminal sends with this URL address HTTP request message to the management specified Equipment.

Step 307: management equipment gathers the page money of the page according to URL described in this URL address acquisition Source.

After user terminal receives described HTTP redirection message, according to the described URL wherein carried Gather the URL address of the page, generate the HTTP request message with this URL address, wherein, institute The web page resources stating the URL collection page is present in the management equipment specified, and management equipment obtains page resource By http response, this page resource is sent to user terminal afterwards, can be certainly on user terminal browser Dynamic this URL that assembles gathers the page, thus realizes automatically having access to URL and gather the target of the page.

An enterprises, major part employee may come to visit because of the business demand that department is unique Ask various webpage, have the URL address of quite a few webpage (especially increasing webpage newly) not to be recorded In URL storehouse, now whether this webpage meets enterprise security standard is unknown.For a user, its Do not let pass the most without reason the when of accessing these URL, caused potential potential safety hazard；The most it is not blocked And have influence on the experience of user.Now this access is not cleared, but is directed to the URL that management equipment provides Gather to come on the page, not only ensure that safety but also taken into account the experience of user.For another one angle, In traditional approach, user it may also be desirable to pick up the telephone or initiate from other positions an approval process and joins It is manager, the inconvenience brought to user.After using the scheme of the application, user can pass through safety The guiding of equipment is automatically related to manage equipment side and is realized the examination of the URL address to webpage to be visited.

Step 308: user terminal gathers the page according to this URL and submits the URL with described webpage to be visited to The access request of address is to manager.

Concrete, after user terminal access gathers the page to the URL specified on management equipment, according to this URL Gather the information of the page, submit the access request of the URL address with user terminal webpage to be visited to, So that manager examines the URL address of described webpage to be visited.In a preferred example, URL gathers The page can include URL address input field position, it is allowed to user inputs the URL address of the above-mentioned page to be visited, In addition URL gathers and can also include that priority, process limited, contact method etc. are one or more auxiliary on the page Help input field.These auxiliary input fields can help to manage equipment side and enter URL address timely and effectively Row examines.Assuming to use manual review, priority and process limited can allow manager to solve as soon as possible Those urgent web page access demands, it is possible in time examination result is informed by Email or other modes To user terminal.

Step 309: management equipment side examines the URL address of described webpage to be visited.

In the example of a manual review, manager can check described webpage to be visited by management equipment The web page contents of URL address, and evaluate whether this webpage is secure and trusted according to the web page contents of this webpage Webpage, the most then this webpage is the webpage that user terminal can access；If it is not, then this webpage is for using The webpage that family terminal cannot access, thus obtain examination result.In other examples, can use automatically The mode examined.

Step 310: management equipment returns the examination result of the URL address of described webpage to be visited and sets to safety Standby.

Step 311: safety equipment update URL according to the examination result of the URL address of described webpage to be visited Storehouse.

Concrete, when examination result be by time, the URL address of the safety equipment described webpage to be visited of interpolation To URL white list；When examination result is obstructed out-of-date, and safety equipment then add described webpage to be visited URL address is to URL blacklist, thus realizes updating URL storehouse.

There is above-described embodiment visible, when safety equipment do not find the URL of webpage to be visited with user terminal During the URL address of address coupling, be not the access directly blocking described user terminal, but generate with URL gathers the HTTP redirection message of the URL address of the page, so that user terminal is according to this URL ground Location accesses specifies the URL in management equipment to gather the page, submits the URL address with webpage to be visited to Access request to managing equipment side, the webpage described to be visited that therefore safety equipment then return according to manager The examination result of URL address updates URL storehouse, thus realizes the individual demand according to enterprise and update URL Storehouse.
