Abstract: Some embodiments provide a system for lossless packet monitoring in a virtualized. The system, using a virtual tap, intercepts packets from a data compute node operating on a host machine, between the data compute node (DCN) and a managed forwarding element on the host. As part of the lossless packet mirroring, the virtual tap forwards data files related to the mirrored packets to a traffic monitoring. The traffic monitoring application stores the data received from the virtual tap and is capable of performing analytics on the stored data. In some embodiments, the system also includes a central controller that communicates with the other elements of the system to manage the traffic monitoring.

Abstract: An anti-alteration system for Web contents is described. A public-web-server computer stores safe web files encrypted from the original web contents, including static files (such as html, text, jpg, gif, wav, mp3, asp, exe, etc.) and dynamic files (such as php, perl, java script, etc.). An original-Web-server computer stores the original web content and connects to the public-web-server computer through a protected access port such as a firewall. When a website visitor's request is received, the public web server checks the safe web file, and if the safe Web file has not been altered, the web server sends back the web content decrypted from the safe web file. A recovery module is used for encrypting the web content to the safe web file on the original web server computer.
