Abstract

A method for managing a plurality of messages associated with an online messaging system is provided. The method may include receiving a message from a messaging source. The method may also include determining whether the messaging source associated with the received message is trusted. The method may further include tagging the received message or storing the received message, wherein the tagging and the storing is based on the determination that the messaging source is not trusted. The method may additionally include validating the received message.

Claims

1. A method for managing a plurality of messages associated with an online messaging system, the method comprising:

receiving a message from a messaging source;

determining whether the messaging source associated with the received message is trusted;

tagging the received message or storing the received message, wherein the tagging and the storing is based on the determination that the messaging source is not trusted; and

validating the received message.

2. The method of claim 1, wherein the messaging source comprises at least one of a network connection, an application, and an input queue.

3. The method of claim 1, wherein determining whether the messaging source associated with the received message is trusted comprises determining whether an attribute associated with the received message has been set to flag the received message as being sent from an untrusted source.

4. The method of claim 3, wherein the setting of the attribute associated with the received message is either manually set by an administrator or automatically set according to a plurality of predetermined criteria identifying a plurality of untrusted sources.

5. The method of claim 1, wherein the tagging of the received message comprises storing a taint flag in a field in a header associated with an application messaging payload for a plurality of data associated with the received message or storing a taint flag in a plurality of metadata associated with the received message.

6. The method of claim 1, wherein storing the received message comprises storing the received message in a data store or a repository.

7. The method of claim 1, wherein validating the received message further comprises:

determining whether it is possible to sanitize or to verify the received message is safe;

determining whether to maintain or unset the tagging of the received message based on the determination that is possible to sanitize or to verify the received message is safe; and

sending the received message back into the online messaging system based on the determination that is possible to sanitize or to verify the received message is safe.

8. A computer system for managing a plurality of messages associated with an online messaging system, the computer system comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising;

receiving a message from a messaging source;

determining whether the messaging source associated with the received message is trusted;

tagging the received message or storing the received message, wherein the tagging and the storing is based on the determination that the messaging source is not trusted; and

validating the received message.

9. The computer system of claim 8, wherein the messaging source comprises at least one of a network connection, an application, and an input queue.

10. The computer system of claim 8, wherein determining whether the messaging source associated with the received message is trusted comprises determining whether an attribute associated with the received message has been set to flag the received message as being sent from an untrusted source.

11. The computer system of claim 10, wherein the setting of the attribute associated with the received message is either manually set by an administrator or automatically set according to a plurality of predetermined criteria identifying a plurality of untrusted sources.

12. The computer system of claim 8, wherein the tagging of the received message comprises storing a taint flag in a field in a header associated with an application messaging payload for a plurality of data associated with the received message or storing a taint flag in a plurality of metadata associated with the received message.

13. The computer system of claim 8, wherein storing the received message comprises storing the received message in a data store or a repository.

14. The computer system of claim 8, wherein validating the received message further comprises:

determining whether it is possible to sanitize or to verify the received message is safe;

determining whether to maintain or unset the tagging of the received message based on the determination that is possible to sanitize or to verify the received message is safe; and

sending the received message back into the online messaging system based on the determination that is possible to sanitize or to verify the received message is safe.

15. A computer program product for managing a plurality of messages associated with an online messaging system, the computer program product comprising:

one or more computer-readable storage devices and program instructions stored on at least one of the one or more tangible storage devices, the program instructions executable by a processor, the program instructions comprising;

program instructions to receiving a message from a messaging source;

program instructions to determine whether the messaging source associated with the received message is trusted;

program instructions to tag the received message or storing the received message, wherein the tagging and the storing is based on the determination that the messaging source is not trusted; and

program instructions to validate the received message.

16. The computer program product of claim 15, wherein the messaging source comprises at least one of a network connection, an application, and an input queue.

17. The computer program product of claim 15, wherein determining whether the messaging source associated with the received message is trusted comprises determining whether an attribute associated with the received message has been set to flag the received message as being sent from an untrusted source.

18. The computer program product of claim 17, wherein the setting of the attribute associated with the received message is either manually set by an administrator or automatically set according to a plurality of predetermined criteria identifying a plurality of untrusted sources.

19. The computer program product of claim 15, wherein the tagging of the received message comprises storing a taint flag in a field in a header associated with an application messaging payload for a plurality of data associated with the received message or storing a taint flag in a plurality of metadata associated with the received message.

20. The computer program product of claim 15, wherein storing the received message comprises storing the received message in a data store or a repository.
