20090126011APPLICATION SECURITY MODEL - Performing security sensitive operations with an application security model. Security agnostic code is executed. The security agnostic code is identified as not having authorization to perform a security sensitive operation. Executing the security agnostic code includes calling code identified as security safe critical code. In response to the security agnostic code calling the security safe critical code, the security safe critical code is executed. The security safe critical code includes functionality for performing validity checks. Executing the security safe critical code includes performing an validity check for the security agnostic code. When the security agnostic code passes the validity check, code identified as security critical code is called. In response to the security safe critical code calling the security critical code, the security critical code is executed. The security critical code is authorized to perform the security sensitive operation.05-14-2009
20090328134LICENSING PROTECTED CONTENT TO APPLICATION SETS - The present invention extends to methods, systems, and computer program products for licensing protected content to application sets. Embodiments of the invention permit a local machine to increase its participation in authorizing access to protected content. For example, an operating system within an appropriate computing environment is permitted to determine if an application is authorized to access protected content. Thus, the application is relieved from having to store a publishing license. Further, authorization decisions are partially distributed, easing the resource burden on a protection server. Accordingly, embodiments of the invention can facilitate more robust and efficient authorization decisions when access to protected content is requested.12-31-2009
20100180126SECURE REMOTE PASSWORD VALIDATION - A method, system and apparatus for secure password validation can include a local authentication process configured for coupling both to local authentication data and to a remote authentication process. The system also can include a comparator disposed in the local authentication process and programmed to detect an extended password string in the local authentication data. Finally, the system can include a remote authentication handler disposed in the local authentication process and programmed to outsource password validation to the remote authentication process responsive to the comparator detecting an extended password string retrieved for a supplied user identifier. Preferably, the remote authentication handler can be a remote procedure call to the remote authentication process.07-15-2010

20080244736MODEL-BASED ACCESS CONTROL - Access control as it relates to policies or permissions is provided based on a created model. A security policy is abstracted and can be independent of a mechanism used to protect resources. An asbstract model of a potential user, user role and/or resource is created without associating a specific individual and/or resource with a model. These abstract user models and abstract resource models can be used across applications or within disparate applications. The abstracted security policies can be selectively applied to the model. Specific users and/or resources can be associated with one or more abstract user model or abstract resource model. The models can be nested to provide configurations for larger systems.10-02-2008
20080282315Host control of partial trust accessibility - Various technologies and techniques are disclosed for providing host control of partial trust accessibility. A framework allows libraries to be identified as partial trust callers allowed to indicate that the libraries are allowed to be called from partially trusted code by default. The framework allows libraries to be identified as partial trust callers enabled to indicate the libraries could be called from partially trusted code, but not by default. A hosting application is notified that a particular library has been loaded. If the particular library has been identified as partial trust callers allowed, then a determination is received from the hosting application on whether to remove or keep partial trust accessibility for the particular library. If the particular library has been identified as partial trust callers enabled, then a determination is received from the hosting application on whether or not to enable partial trust accessibility for the particular library.11-13-2008
20080301780ACCESS CONTROL NEGATION USING NEGATIVE GROUPS - The subject disclosure pertains to systems and methods that facilitate managing groups entities for access control. A negative group is defined using a base group, where the negative group associated with a base group includes any entities not included in the base group. Negative groups can be implemented using certificates rather than explicit lists of negative group members. A certificate can provide evidence of membership in the negative group and can be presented for evaluation to obtain access to resources. Subtraction groups can also be used to manage access to resources. A subtraction group can be defined as the members of a first group, excluding any members of a second group.12-04-2008
20080307486ENTITY BASED ACCESS MANAGEMENT - The subject disclosure pertains to systems and methods that facilitate entity-based for access management. Typically, access to one or more resources is managed based upon identifiers assigned to entities. Groups of identifiers can be assigned to access rights. An authority component can manage an exclusion group that excludes an entity, regardless of the identifier utilized by the entity. Access control components can utilize exclusion groups in access policies to define access rights to a resource.12-11-2008
20080313712TRANSFORMATION OF SEQUENTIAL ACCESS CONTROL LISTS UTILIZING CERTIFICATES - The subject disclosure pertains to systems and methods that facilitate managing access control utilizing certificates. The systems and methods described herein are directed to mapping an access policy as expressed in an access control list to a set of certificates. The set of certificates can be used to grant access to resources in the manner described by the ACL. The certificates can be distributed to entities for use in obtaining access to resources. Entities can present certificates to resources as evidence of their right to access the resources. The access logic of the sequential ACL can be transformed or mapped to a set of order independent certificates. In particular, each entry, position of the entry in the list and any preceding entries can be analyzed. The analysis can be used to generate order independent certificates that provide access in accordance with the access policy communicated in the ACL.12-18-2008
20100023767API for Diffie-Hellman secret agreement - Various technologies and techniques are disclosed for implementing a Diffie-Hellman secret agreement. An application programming interface is provided that is operable to allow a first computer to generate a Diffie-Hellman secret agreement for communicating securely with a second computer over an insecure channel. A get public key operation is performed upon receiving a request to perform the get public key operation. The get public key operation gets a public key of the first computer. A retrieval operation is performed upon receiving a request to perform the retrieval operation. The retrieval operation retrieves the Diffie-Hellman secret agreement upon supplying a public key of the second computer.01-28-2010
20100293608EVIDENCE-BASED DYNAMIC SCORING TO LIMIT GUESSES IN KNOWLEDGE-BASED AUTHENTICATION - Techniques to provide evidence-based dynamic scoring to limit guesses in knowledge based authentication are disclosed herein. In some aspects, an authenticator may receive an input from a user in response to a presentation of a personal question that enables user access to a restricted resource. The authenticator may determine that the input is not equivalent to a stored value, and thus is an incorrect input. The authenticator may then determine whether the input is similar to a previous input received from the user. A score may be assigned to the input. When the input is determined to be similar to the previous input, the score may be reduced. Another request for an input may be transmitted by the authenticator when a sum of the score and any previous scores of the session is less than a threshold.11-18-2010
