Securely managing network connections

1. A method comprising:

receiving one or more messages from a plurality of computing devices connected through a network, the one or more messages indicating actual connections among the plurality of computing devices;

comparing, by one or more processors, the actual connections to a list of expected connections indicated by a connections master file that comprises connection information for the plurality of computing devices;

responsive to detecting one or more differences between the list of expected connections and the actual connections, providing a notification indicating the one or more differences to a log file or a notification area of a user interface; and

responsive to a determination that one of the actual connections between two computing devices of the plurality of computing devices is an unauthorized connection, pushing a configuration file to each of the two computing devices to delete a rule corresponding to the unauthorized connection.

2. The method of claim 1 , wherein the actual connections are determined from configuration files included in each of the plurality of computing devices.

3. The method of claim 1 , wherein each expected connection in the list defines a first computing device of the plurality of computing devices and a second computing device of the plurality of computing devices between which the expected connection exists.

4. The method of claim 1 , wherein each of the actual connections among the plurality of computing devices comprises a protocol, a port number, a port number range, or a security group.

5. The method of claim 1 , wherein each detected difference indicates an unauthorized connection or an inaccuracy of the master connection file.

6. The method of claim 1 , further comprising determining, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether the list of expected connections is inaccurate.

7. The method of claim 6 , further comprising, responsive to a determination that the list of expected connections is inaccurate, updating the connections master file.

8. The method of claim 1 , further comprising determining, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether one or more of the actual connections are unauthorized.

9. A system comprising:

a memory comprising instructions; and

one or more processors operatively coupled to the memory to execute the instructions, wherein the instructions cause the one or more processors to:

receive one or more messages from a plurality of computing devices connected through a network, the one or more messages indicating actual connections among the plurality of computing devices;

compare, by the one or more processors, the actual connections to a list of expected connections indicated by a connections master file that comprises connection information for the plurality of computing devices;

responsive to a detection of one or more differences between the list of expected connections and the actual connections, provide a notification indicating the one or more differences to a log file or a notification area of a user interface; and

responsive to a determination that one of the actual connections between two computing devices of the plurality of computing devices is an unauthorized connection, push a configuration file to each of the two computing devices to delete a rule corresponding to the unauthorized connection.

10. The system of claim 9 , wherein the actual connections are determined from configuration files included in each of the plurality of computing devices.

11. The system of claim 9 , wherein each expected connection in the list defines a first computing device of the plurality of computing devices and a second computing device of the plurality of computing devices between which the expected connection exists.

12. The system of claim 9 , wherein each of the actual connections among the plurality of computing devices comprises a protocol, a port number, a port number range, or a security group.

13. The system of claim 9 , wherein each detected difference indicates an unauthorized connection or an inaccuracy of the master connection file.

14. The system of claim 9 , wherein the one or more processors are further to:

determine, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether the list of expected connections is inaccurate.

15. The system of claim 14 , wherein the one or more processors are further to, responsive to a determination that the list of expected connections is inaccurate, update the connections master file.

16. The system of claim 9 , wherein the one or more processors are further to determine, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether one or more of the actual connections are unauthorized.

17. A non-transitory computer readable medium having instructions stored thereon which, when executed by one or more processors, cause the one or more processors to:

receive one or more messages from a plurality of computing devices connected through a network, the one or more messages indicating actual connections among the plurality of computing devices;

compare the actual connections to a list of expected connections indicated by a connections master file that comprises connection information for the plurality of computing devices;

responsive to a detection of one or more differences between the list of expected connections and the actual connections, provide a notification indicating the one or more differences to a log file or a notification area of a user interface; and

responsive to a determination that one of the actual connections between two computing devices of the plurality of computing devices is an unauthorized connection, push a configuration file to each of the two computing devices to delete a rule corresponding to the unauthorized connection.

18. The non-transitory computer readable medium of claim 17 , wherein the actual connections are determined from configuration files included in each of the plurality of computing devices.

19. The non-transitory computer readable medium of claim 17 , wherein each expected connection in the list defines a first computing device of the plurality of computing devices and a second computing device of the plurality of computing devices between which the expected connection exists.

20. The non-transitory computer readable medium of claim 17 , wherein each of the actual connections among the plurality of computing devices comprises a protocol, a port number, a port number range, or a security group.

21. The non-transitory computer readable medium of claim 17 , wherein each detected difference indicates an unauthorized connection or an inaccuracy of the master connection file.

22. The non-transitory computer readable medium of claim 17 , wherein the one or more processors are further to determine, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether the list of expected connections is inaccurate.

23. The non-transitory computer readable medium of claim 22 , wherein the one or more processors are further to, responsive to a determination that the list of expected connections is inaccurate, update the connections master file.

24. The non-transitory computer readable medium of claim 17 , wherein the one or more processors are further to determine, based on one or more detected differences between the list of expected connections and the actual connections among the plurality of computing devices, whether one or more of the actual connections are unauthorized.
