An apparatus in one embodiment comprises a plurality of host devices configured to support execution of applications on behalf of one or more tenants of cloud infrastructure. The apparatus further comprises a secure data proxy implemented utilizing at least one of the host devices. The secure data proxy comprises non-persistent storage configured to store data required for execution of at least one of the applications. The data is obtained by the secure data proxy from persistent storage in a storage system external to the cloud infrastructure. The secure data proxy is configured to perform cryptographic operations in conjunction with transfer of the data between the persistent storage of the external storage system and the non-persistent storage of the secure data proxy. The secure data proxy may be further configured to perform deduplication operations in conjunction with transfer of the data between the persistent storage and the non-persistent storage.

Secure data proxy for cloud computing environments

Disclosed is a method of supporting security policies and security levels associated with processes and applications. A security level is associated with a process independent of a user executing the process. When secure data is to be accessed, the security level of the process is evaluated to determine whether data access is to be granted. Optionally, the security level of a user of the process is also evaluated prior to providing data access.

Method and system for securing data

A method is disclosed for executing a secure virtual machine stored in encrypted form in IaaS cloud such as Microsoft Azure or Amazon Web Services. A first execution environment comprising a key access protocol for accessing a cipher key is initiated. The first execution environment executes the secure virtual machine by accessing a secret for use in deciphering the encrypted form of the secure virtual machine and providing same to allow the secure virtual machine to be executed.

Method and system for secure instantiation of an operation system within the cloud

In one example, a proxy server acts as a gateway to a website and modifies the traffic between a web browser on a user device and the website server, as necessary to request protection by providing step-up authentication and/or transaction verification. The proxy server blocks transactions when protection is required but has not occurred (either because the authentication was not proper or due to the detection of another problem). Associated methods and systems are also provided.

Online secure transaction verification system proxy server and method

A method for providing authentication of a user of a recipient unit when the recipient unit is off-line includes storing one or a plurality of one-time challenge-reply sets based on an on-line communication with a sender unit. In one example, each of the one-time challenge-reply sets includes at least a one-time challenge-reply pair for use in off-line authentication of the user for a particular resource available through the recipient unit. When the user is offline, the method includes selecting at least one of the plurality of stored one-time challenge-reply sets for off-line authentication of the user for the particular resource available through the recipient unit. The one-time challenge-reply sets may be associated with an article.

Offline methods for authentication in a client/server authentication system

A method for providing authentication of a user of a recipient unit when the recipient unit is off-line includes storing one or a plurality of challenge-reply sets associated with an article based on an on-line communication with a sender unit. Each of the challenge-reply sets includes at least a challenge-reply pair for use in off-line authentication of the user for a particular resource available through the recipient unit. When the user is offline, the method includes selecting at least one of the plurality of stored challenge-reply sets for off-line authentication of the user for the particular resource available through the recipient unit.

A system and method employs a password rule data provider that provides password generation rule data to a notification device, such as visual display device or audible output device. A password data evaluator, such as a per character password data evaluator, continuously evaluates password character data as its being entered and compares each character to the password generation rule data. A dynamic status data generator dynamically generates password rule status data, such as visual indication of which rule has been met or which rule has not been met as password data is being entered.
