a memory to store a first list of connections among a plurality of networked resources; and
one or more processors operatively coupled to the memory, the one or more processors to:
detect, by one or more processors, one or more differences between the first list of connections and a second list of connections of a first networked resource of the plurality of networked resources, wherein the first list of connections is indicative of respective configurations of the plurality of networked resources, the respective configurations comprising communication permissions among the plurality of networked resources, and wherein the second list of connections indicates communication permissions at the first networked resource; and
update, by the one or more processors, the second list of connections based on the one or more differences to align the second list of connections with the first list of connections.
12. The system of claim 11 , wherein the first list of connections comprises a list of desired connections among the plurality of networked resources.
13. The system of claim 12 , wherein each desired connection in the list of desired connections defines two network resources between which the desired connection exists.
14. The system of claim 11 , wherein the second list of connections indicates existing connections between the first networked resource and the plurality of networked resources.
15. The system of claim 11 , wherein to update the second list of connections the one or more processors are to:
add or remove one or more connections to the first list of connections based on one or more differences between the second list of connections and the first list of connections.
16. The system of claim 11 , wherein the one or more processors are further to:
obtain, for each of one or more of the plurality of networked resources, a connection indication file indicating one or more actual connections maintained by the networked resource.
17. The system of claim 11 , wherein the one or more processors are further to: provide a notification of the one or more differences between the first list of connections and the second list of connections.
18. The system of claim 17 , wherein each of the one or more differences indicates an unauthorized connection or an inaccuracy of the second list of connections.
19. The system of claim 11 , wherein to detect the one or more differences between the first list of connections and the second list of connections of the first networked resource, the one or more processors are to:
determine whether a particular desired connection of the first list of connections has a matching actual connection among the second list of connections of the first networked resource.
20. The system of claim 11 , wherein each connection in the first list of connections among the plurality of networked resources comprises a protocol, a port number, a port number range, or a security group.
21. 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:
store a master connection file comprising a first list of connections indicative of respective configurations of a plurality of networked resources, the respective configurations comprising communication permissions among the plurality of networked resources;
detect, by the one or more processors, one or more differences between the master connection file and a first connection indication file of a first networked resource and a second connection indication file of a second networked resource, wherein the first connection indication file comprises a second list of connections maintained between the first networked resource and the plurality of networked resources and the second connection indication file comprises a third list of connections maintained among the second networked resource and the plurality of networked resources, the second and third lists of connections comprising communication permissions; and
update, by the one or more processors, the first and second connection indication files based on the one or more differences between the master connection file and the first and second connection indication files to align the second list of connections and the third list of connections with the first list of connections.
