A method for providing authorized remote access to a computing environment provided by a virtual machine, includes the step of requesting, by a client machine, access to a resource. A collection agent gathers information about the client machine. A policy engine receives the gathered information. The policy engine makes an access control decision based on the received information. A computing environment already associated with the user is identified in response to the received information, the identified computing environment provided by a virtual machine. A broker server establishes, responsive to the access control decision, a connection between the client machine and the identified computing environment.

For enhanced access control, a client includes a token in each read or write command sent to a block storage device. The block storage device evaluates the token to determine whether or not read or write access is permitted at a specified logical block address. For example, the token is included in the logical block address field of a SCSI read or write command. The client may compute the token as a function of the logical block address of a data block to be accessed, or a metadata server may include the token in each block address of each extent reported to the client in response to a metadata request. For enhanced security, the token also is a function of a client identifier, a logical unit number, and access rights of the client to a particular extent of file system data blocks.

Embodiments of the present disclosure provide a method and system for implicitly authenticating a user to access controlled resources. The system receives a request to access the controlled resources. The system then determines a user behavior score based on a user behavior model, and recent contextual data about the user. The user behavior score facilitates identifying a level of consistency between one or more recent user events and a past user behavior pattern. The recent contextual data, which comprise a plurality of data streams, are collected from one or more user devices without prompting the user to perform an action explicitly associated with authentication. The plurality of data streams provide basis for determining the user behavior score, but a data stream alone provides insufficient basis for the determination of the user behavior score. The system also provides the user behavior score to an access controller of the controlled resource.
