File redirection technology based virtualized security desktop

Abstract

The invention discloses a file redirection technology based virtualized security desktop. Validity in using the security desktop is guaranteed through a login control module; operation behavior results of users can be reliably protected by an encrypted virtual storage file system; the operation behavior results of the users in the virtualized security desktop are 'internally' redirected to the encrypted virtual storage file system through a user operation middle layer and the whole redirection process is encrypted and monitored under a communication encryption module and a black and white list control module. The virtualized security desktop system is 'totally separated' from an original desktop, operations of adhering, copying, shifting and the like of the files cannot be performed between the virtualized security desktop system and the original desktop; the files on an original desktop system are mapped to the same catalog on the virtualized desktop; results (files, register lists, temporary cache and the like) generated from operation of the users in the virtualized desktop are encrypted for redirection treatment, and all the operations in the virtualized desktop are guaranteed to be safe, reliable and controllable.

Description

technical field [0001] The invention belongs to host security in the field of information security, and relates to virtualization technology based on file redirection technology, communication encryption technology, host login control technology, etc., to realize login control of virtual desktop, system files, user files, registration Data operations such as tables and files are redirected to prevent internal data leakage and achieve desktop environment security. Background technique [0002] Since Microsoft announced that it will officially stop technical support, system and patch updates for Windows XP on April 8, 2014, according to the report of the market research company Net Applicationd, among the 1.4 billion Windows PCs worldwide in July 2013 (Microsoft data ) 37.2% of personal computers are still using the window XP operating system, and among them, China ranks 72.1%. It can be seen that domestic industry users and individual users are particularly dependent on wind...

Problems solved by technology

[0004] For such a situation, the usual strategy is to directly upgrade to other systems. However, large and medium-sized enterprises, military forces, and agencies, etc., rely heavily on software infrastructure, operating system upgrades are complex, uncertain, and return on investment. Consider that the implementation of a large-scale upgrade will generally be delayed by about 5 years, and the data in the computer will face multiple security risks during this period

[0005] At present, although many information security-related companies at home and abroad have done in-depth research on host data security and released various security protection systems, this protection system is mainly based on processes and functions. Restricting operational behaviors (such as printing and burning) can alleviate these hidden dangers to a certain extent, but it cannot fundamentally solve the hidden dangers of data leakage faced by the host (such as leaking incidents and Yanzhaomen incidents that have occurred in recent years)
