5. The apparatus of claim 1 , wherein the indication that the instance of the application is attempting to initiate the TCP connection includes a trace associated with a source of an instruction causing the instance of the application to attempt to initiate the TCP connection.

6. The apparatus of claim 1 , wherein the application is a first application, the processor is configured to initiate the instance of the first application within the sandbox environment based on the sandbox environment recognizing the first application,

the processor is configured to exclude an instance of a second application from executing with the sandbox environment based on the sandbox environment not recognizing the second application.

7. The apparatus of claim 1 , wherein the set of indications of allowed behavior specific to the application is defined and associated with the application prior to initiating the instance of the application within the sandbox environment.

8. The apparatus of claim 1 , wherein the TCP connection is a first TCP connection, the processor configured to receive, from the monitor associated with the sandbox environment, an indication that the instance of the application is attempting to initiate a second TCP connection different from the first TCP connection, the processor configured to allow the instance of the application to initiate the second TCP connection based on an indication of initiating the second TCP connection being within the set of indications of allowed behavior specific to the application.

9. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the instructions comprising code to cause the processor to:

receive a set of indications of allowed behavior specific to an application;

initiate an instance of the application within a sandbox environment;

receive, from a monitor associated with the sandbox environment, an indication that the instance of the application is attempting to initiate a network connection; and

terminate the instance of the application based on an indication of initiating the network connection not being within the set of indications of allowed behavior specific to the application.

10. The non-transitory processor-readable medium of claim 9 , wherein the network connection is a first network connection, the code further comprising code to cause the processor to:

receive, from the monitor associated with the sandbox environment, an indication that the instance of the application is attempting to initiate a second network connection different from the first network connection; and

allow the instance of the application to initiate the second network connection based on an indication of initiating the second network connection being within the set of indications of allowed behavior specific to the application.

11. The non-transitory processor-readable medium of claim 9 , wherein the application is a first application, the code to cause the processor to initiate includes code to cause the processor to initiate the instance of the first application within the sandbox environment based on an instruction from an instance of a second application to initiate the instance of the first application, the set of indications of allowed behavior specific to the first application being based on a set of indications of allowed behavior specific to the second application.

12. The non-transitory processor-readable medium of claim 9 , wherein the network connection is a Transmission Control Protocol (TCP) connection.

13. The non-transitory processor-readable medium of claim 9 , further comprising code to cause the processor to:

define and store a signature for the application using a cryptographic hash value of a file associated with the application in response to classifying the attempting to initiate the network connection as an anomalous behavior for the application.

14. The non-transitory processor-readable medium of claim 9 , wherein the application is a first application, the code to cause the processor to initiate includes code to cause the processor to initiate the instance of the first application within the sandbox environment based on the sandbox environment recognizing the first application,

the code further comprising code to cause the processor to exclude an instance of a second application from executing within the sandbox environment based on the sandbox environment not recognizing the second application.

15. The non-transitory processor-readable medium of claim 9 , wherein the indication that the instance of the application is attempting to initiate the network connection includes a trace associated with a source of an instruction causing the instance of the application to attempt to initiate the network connection.

16. A method, comprising:

receiving, at a processor, a set of indications of allowed behavior specific to a first application;

receiving, at the processor a set of indications of allowed behavior specific to a second application different from the first application;

initiating, using the processor, an instance of the first application and an instance of the second application within a sandbox environment;

receiving, from a monitor associated with the sandbox environment, an indication that the instance of the first application is attempting to initiate a network connection;

terminating, using the processor, the instance of the first application based on an indication of initiating the network connection not being within the set of indications of allowed behavior specific to the first application;

receiving, from the monitor associated with the sandbox environment, an indication that the instance of the second application is attempting to initiate the network connection; and

allowing the instance of the second application to initiate the network connection based on an indication of initiating the network connection being within the set of indications of allowed behavior specific to the second application.

17. The method of claim 16 , wherein the network connection is a Transmission Control Protocol (TCP) connection.

18. The method of claim 16 , further comprising:

defining and storing a signature for the first application using a cryptographic hash value of a file associated with the first application in response to classifying the first application attempting to initiate the network connection as an anomalous behavior for the first application.
