System and method for allowing executing application in compartment that allow access to resources
View Patent ↗A method of producing a compartment specification for an application, the method comprising executing the application; determining resource requests made by the executing application; and recording the resource requests in the compartment specification.
1. A method of producing a compartment specification for an application, comprising:
executing the application;
determining a resource request made by the executing application, wherein determining the resource request comprises defining wrapper functions that are called when the executing application makes the resource request, wherein the wrapper functions are to call associated system functions that handle the resource request, and wherein the wrapper functions are provided in a wrapper library; and
recording a permission corresponding to the resource request in the compartment specification for the application, wherein the compartment specification contains a list of resources that the application is permitted to access.
2. A method as claimed in claim 1 , wherein determining the resource request further comprises trapping the resource request made by the executing application.
3. A method as claimed in claim 1 , wherein executing the application comprises executing the application in a compartment that allows access to at least all resources required by the application.
4. A method as claimed in claim 3 , wherein the compartment allows access to all resources.
5. A method as claimed in claim 1 , comprising executing the application in a compartment according to the compartment specification such that requests made by the application for resources that are not listed in the compartment specification are unsuccessful.
6. A non-transitory computer readable medium storing machine readable instructions, which when executed by a processor perform a method for producing a compartment specification for an application, the machine readable instructions comprising code to:
execute the application;
determine a resource request made by the executing application, wherein the code to determine the resource request comprises code to define wrapper functions that are called when the executing application makes the resource request, wherein the wrapper functions are to call associated system functions that handle the resource request, and wherein the wrapper functions are provided in a wrapper library; and
record a permission corresponding to the resource request in the compartment specification for the application, wherein the compartment specification contains a list of resources that the application is permitted to access.
7. The non-transitory computer readable medium as claimed in claim 6 , wherein the code to determine the resource request further comprises code to trap the resource request made by the executing application.
8. The non-transitory computer readable medium as claimed in claim 6 , wherein the code to execute the application comprises code to execute the application in a compartment that allows access to at least all resources required by the application.
9. The non-transitory computer readable medium as claimed in claim 8 , wherein the compartment allows access to all resources.
10. The non-transitory computer readable medium as claimed in claim 6 , further comprising code to execute the application in a compartment according to the compartment specification such that requests made by the application for resources that are not listed in the compartment specification are unsuccessful.
11. A computer system to produce a compartment specification for an application, comprising:
a memory storing machine readable instructions, which when executed are to:
execute the application;
determine a resource request made by the executing application, wherein the machine readable instructions to determine the resource request comprises machine readable instructions to define wrapper functions that are called when the executing application makes the resource request, wherein the wrapper functions are to call associated system functions that handle the resource request, and wherein the wrapper functions are provided in a wrapper library; and
record a permission corresponding to the resource request in the compartment specification for the application, wherein the compartment specification contains a list of resources that the application is permitted to access; and
a processor to execute the machine readable instructions stored in the memory.
