Abstract

Controlling access to secure resources of a data processing system is provided. An input-to-output mapping of an application installed on the data processing system is generated that determines whether a secure resource in the data processing system is shared with an external entity associated with the application and under what specified conditions. It is determined whether the specified conditions exist during runtime of the application. In response to determining that the specified conditions do not exist during runtime of the application, sharing of the secure resource of the data processing system with the external entity associated with the application is prevented. In response to determining that the specified conditions do exist during runtime of the application, sharing of the secure resource of the data processing system with the external entity associated with the application is allowed.

a bus system;

a storage device connected to the bus system, wherein the storage device stores computer readable program code; and

a processor unit connected to the bus system, wherein the processor unit executes the computer readable program code to generate an input-to-output mapping of an application installed on the data processing system that determines whether a secure resource in the data processing system is shared with an external entity associated with the application and under what specified conditions;

determine whether the specified conditions exist during runtime of the application;

prevent sharing of the secure resource of the data processing system with the external entity associated with the application in response to determining that the specified conditions do not exist during runtime of the application; and

allow sharing of the secure resource of the data processing system with the external entity associated with the application in response to determining that the specified conditions do exist during runtime of the application.

2. The data processing system of claim 1, wherein the processor further executes the computer readable program code to monitor a number of accesses sharing the secure resource of the data processing system with the external entity associated with the application;

determine whether the number of accesses sharing the secure resource of the data processing system exceeded an access control threshold value corresponding to the secure resource;

detect whether the specified conditions exist during runtime of the application in response to determining that the number of accesses sharing the secure resource of the data processing system does not exceed the access control threshold value corresponding to the secure resource; and

terminate the sharing of the secure resource of the data processing system with the external entity associated with the application in response to determining that the number of accesses sharing the secure resource of the data processing system does exceed the access control threshold value corresponding to the secure resource.

3. The data processing system of claim 1, wherein the processor further executes the computer readable program code to receive a chunk specification that specifies a set of code chunks within the application, each particular code chunk in the set of code chunks is associated with a particular set of one or more secure resources of the data processing system that the particular code chunk has access to and a particular external entity that the particular code chunk has been granted permission to communicate with;

receive a set of context-aware security policies that is associated with the application and defines particular conditions under which permission to access secure resources of the data processing system are granted; and

split the application into the set of code chunks based on at least one of the chunk specification and the set of context-aware security policies.

4. The data processing system of claim 3, wherein the processor further executes the computer readable program code to remove direct application programming interface calls by the application to the secure resources of the data processing system;

and require the set of code chunks within the application accessing the secure resources of the data processing system to utilize a set of custom information flow control application programming interfaces located in an information flow control module of the data processing system to enforce the set of context-aware security policies.

5. The data processing system of claim 3, wherein the processor further executes the computer readable program code to generate a manifest file associated with the application that specifies each requested communication between each code chunk in the set of code chunks within the application and a respective external entity that a particular code chunk communicates with and also specifies a particular secure resource that is shared with the respective external entity based on the chunk specification.

6. The data processing system of claim 5, wherein the processor further executes the computer readable program code to verify that selections in the manifest file granting permission to a set of requested external entity communications complies with the set of context-aware security policies;

and display a notification of non-compliant selections in the manifest file granting permission to the set of requested external entity communications.

7. The data processing system of claim 1, wherein the processor further executes the computer readable program code to generate a mapping between a set of context-aware security policies that grant permission to access secure resources of the data processing system and a set of custom information flow control application programming interfaces required to call the secure resources.

8. The data processing system of claim 1, wherein the specified conditions include at least one of a current geographic location of the data processing system, an identity of the external entity associated with the application, and an access control threshold value associated with the secure resource.
