Abstract: The present disclosure provides a method and a device for realizing remote login. The method includes: a terminal server responding to a login request to an internal system from an end user, and recording and saving login information of the end user for logging in to the internal system; and the terminal server judging and analyzing the way the end user logs in to the internal system according to the login information and pre-configured rule, and allowing the end user to log in to and access the internal system if the analyzed result matches the pre-configured rule. The method and device allows for implementations of the SSO authentication and user bind authentication on the aspect of the data flow in the terminal server, simplifies the process of logging in to and accessing the internal system, and improves the information security of the system.

Abstract: The present invention relates to a method, apparatus and system for accessing remote files, wherein the method for accessing remote files comprising the following steps: obtaining download operation information for downloading a file in an operational system server; redirecting the download operation to a file server with safety space; saving a real copy of the downloaded file in the safety space and enumerating a corresponding virtual copy in the safety space. In the present invention, local file operations are redirected to the network file operations of network file storage system by redirecting the download operation on the file in the operational system server to the file server instead of being saved in the local user terminal to realize the “Not to local” effect for the key file. Even when it is power-off and then restarted, the data will not be saved in the local user terminal to achieve an effect close to “physical-like isolation”, which solves the safety problems of the offline key file much better.

Abstract: A method for detecting and defending against a CC attack is disclosed, which comprises the following steps of: recording the number of times m of requests for a webpage and the number of times n of related requests for the webpage within a preset time interval if a user's request of accessing the webpage is a dynamic webpage request; and determining that the webpage is subjected to a CC attack if a value (m?n)/m is greater than or equal to a preset threshold. A corresponding apparatus is further disclosed. The method and the apparatus for detecting and defending against a CC attack of the present disclosure can accurately detect and defend against the CC attack.

Abstract: A method and a device for network traffic control comprising the following steps: detecting actual downlink traffic of a network device; calculating an error e between the actual downlink traffic and predetermined downlink traffic; performing a calculation on the error to obtain PID output according to a PID control formula; calculating scaling of upstream traffic according to the calculated PID output and the downlink traffic; and regulating an upstream traffic threshold according to the scaling. The upstream traffic is increased or reduced in accordance with the actual downlink traffic be means of the correlated regulation and dynamic control of the upstream traffic and the downlink traffic of the network device. As such, traffic control is realized in those applications (e.g. UDP traffic such as P2P streaming media) which themselves lack the traffic control mechanism, and it is possible to make the best of network bandwidth as well.
