In the conventional method for safely accessing the webpage, BHO intercepts and blocks the access of a user, inquires an internet security server for security authentication, determines whether to release the blockage according to the inquiry result of the internet security server, and prolongs the time for the user to access the webpage. In the embodiment of the present invention, in order to reduce the time for a user to access a web page, the time (authentication time) from security authentication to the return of a security authentication result to an internet security server and the time (access time) from sending an HTTP request to the internet server to the return of an access web page to the internet security server are counted, and after analyzing and summarizing the time, the following are found: the authentication time is less than the access time, that is, if the user does not block the access of the user when accessing the webpage, before receiving the access webpage information returned by the internet server, the security authentication result of the internet security server to the webpage is received, and at this time, whether the access webpage information is returned to the user is determined according to the security authentication result. Therefore, the time for waiting the security authentication of the internet security server can be effectively reduced, and the time for the user to safely access the webpage is reduced.
Socket functions of the network layer are used for creating sockets capable of performing network communication, and can be applied to various types of browsers, and application programs call Socket functions to monitor requests, send requests to the internet or respond to network requests through Socket interfaces. In the embodiment of the invention, based on a Socket function, a Hook (Hook) network layer Socket function is provided, an HTTP request initiated to an internet server by a browser is intercepted through the Hook network layer Socket function, URL information of a webpage accessed by the user in the browser is automatically identified, and security authentication is initiated to an internet security server while the HTTP request is initiated to the internet server by the browser. When the webpage data information returns to the user mode network layer, whether the webpage data information is intercepted or not is determined according to a safety authentication result returned by the internet safety server, if the webpage which the user requests to access is judged to be harmful, the webpage data information returned by the webpage is intercepted at the network layer, and the user is prompted.
Fig. 1 is a flowchart illustrating a method for accessing a web page according to an embodiment of the present invention. Referring to fig. 1, the process includes:
step 101, receiving a request sent by a user, acquiring webpage information carried in the request, sending the webpage information to an internet security server, and forwarding the request to an internet server mapped by the webpage information;
in this step, the request may be an HTTP request, and the web page information may be web page URL information.
When a user accesses a webpage, an HTTP request for accessing the webpage is generated on the upper layer of the browser, and URL information of the webpage to be accessed is carried.
In the embodiment of the invention, a Socket Hook layer of a Socket function of a Hook network layer applicable to various browsers is arranged and used for carrying out security monitoring on the internet accessed by a user, acquiring corresponding URL information after intercepting an HTTP request initiated to an internet server by the user through an upper layer of the browser, sending the acquired URL information to the internet security server for security authentication, sending the HTTP request to the internet server without any processing, namely, not blocking the HTTP request from being sent to the internet server, and forwarding the HTTP request to the internet server without blocking through the browser network layer. Meanwhile, the Socket function can be compatible with browsers in other formats, so that the application range is expanded.
And 102, receiving webpage data information returned by the Internet server, carrying out safety processing on the webpage data information according to a safety authentication result of the webpage returned by the Internet safety server, and outputting the webpage data information to a user for browsing.
In this step, as described above, the time (authentication time) from the time when the security authentication is performed to the internet security server to the time when the internet security server returns the security authentication result is shorter than the time (access time) from the time when the HTTP request is sent to the internet server to the time when the internet server returns the access web page, so that the SocketHook layer has received the security authentication result of the internet security server on the web page before receiving the web page data information returned by the internet server, and at this time, according to the security authentication result of the web page, it is determined whether to return the web page data information to the user: if the security authentication result is that the security authentication is passed, returning webpage data information to the user for browsing, if the security authentication result is that the security authentication is not passed, blocking the webpage data information to output to the user, returning security prompt information to the user to prompt the user that the webpage accessed by the user has security risks, if the user determines to browse the webpage according to the security prompt information, triggering to output a forced browsing request to the SocketHook layer, after receiving the forced browsing request, releasing the blocking of the webpage data information to the user, outputting the webpage data information to the user for browsing, and if the user determines not to browse the webpage according to the security prompt information, directly discarding the webpage data information by the SocketHook layer.
In practical application, there may be a situation that a small amount of authentication time is longer than access time, and after receiving webpage data information returned by the internet server, it is queried that the internet security server has not returned the security authentication result of the webpage, a timer may be started, and before the timer expires, if the security authentication result of the webpage is received, security processing is performed on the webpage data information according to the security authentication result of the webpage, and if the security authentication result of the webpage is not received, the webpage data information is processed according to a preset policy, for example, the webpage data information is directly output to a user.

step 201, a user sends an HTTP request to a SocketHook layer through an upper layer of a browser;
step 202, the SocketHook layer receives the HTTP request, acquires URL information carried in the HTTP request, and sends the URL information to the Internet security server;
in the step, through a Hook network layer Socket function, an HTTP request initiated by a browser to an internet server is intercepted, corresponding URL information is obtained, the intercepted URL information initiates a security authentication request to an internet security server, and the content of the security authentication request comprises URL information of a webpage accessed by the browser.
Step 203, the socket hook layer outputs the received HTTP request to a browser network layer, and forwards the HTTP request to an Internet server through the browser network layer;
it should be noted that step 202 and step 203 are not in sequence, and both steps are performed simultaneously, that is, when the corresponding URL information is obtained, the HTTP request initiated by the browser to the internet server is not blocked.
Step 204, receiving and storing security authentication result information returned by the internet security server;
in this step, the security authentication result includes that the security authentication passes or the security authentication fails.
Step 205, receiving webpage data information returned by the internet server through the browser network layer, querying stored security authentication result information of the webpage, and performing security processing on the webpage data information;
in the step, after receiving the returned webpage data information, the SocketHook layer inquires whether the safety authentication result information of the webpage is stored, and if the safety authentication result information of the webpage is not stored, a timer is started, namely a preset timing time is waited; if the webpage data information is stored or the safety authentication result information of the webpage is received before the timer times out, carrying out safety processing on the webpage data information according to the safety authentication result information; and if the safety certification result information of the webpage is not received when the timer times out, processing according to a preset strategy.
And step 206, carrying the webpage data information subjected to the security processing in the HTTP request response, and outputting the webpage data information to the upper layer of the browser for the user to browse.
In the step, if the safety certification result information of the webpage is that the safety certification is passed, the webpage accessed by the user is safe, and webpage data information returned by the internet server is output to the user; if the security authentication result information of the webpage is that the security authentication fails, the webpage accessed by the user is harmful, blocking webpage data information blocked by a Socket function is intercepted, the user is prompted, if the user determines to browse the webpage according to the prompt information, the Socket hook layer releases the blocking of the webpage data information output to the user, and if the user determines not to browse the webpage, the Socket hook layer directly discards the webpage data information.
Therefore, according to the method for accessing the webpage, the URL information in the HTTP request is intercepted while the user sends the HTTP request to the Internet server, and the security authentication is synchronously performed on the Internet security server, so that the HTTP request is not required to be sent to the Internet server after the security authentication result is obtained, the time required by waiting for the Internet security server to perform the security authentication is effectively reduced, the time for the user to safely access the webpage is reduced, and the user experience is improved; furthermore, by setting a Socket hook layer, a Socket function which can be supported by each browser is utilized to perform URL information interception, webpage data information security monitoring and blocking, so that the security access of all browsers is supported, and the performance of a user for accessing the webpage is not influenced.
