Access anomaly notification in a storage network
A processing system operates by: detecting an access anomaly associated with an access request from a requestor for a set of encoded data slices, the access anomaly having an unfavorable access pattern, wherein the set of encoded data slices is dispersed storage error encoded and stored in at least one storage unit of the storage network; denying the access request in response to detecting the access anomaly; generating, based on the unfavorable access pattern, an anomaly detection indicator identifying the requestor; and sending the anomaly detection indicator to other devices of the storage network.
1. A method for execution by a computing device that includes a processor, the method comprising:
detecting an access anomaly associated with an access request from a requestor for a set of encoded data slices, the access anomaly having an unfavorable access pattern, wherein the set of encoded data slices is dispersed storage error encoded and stored in at least one storage unit of a storage network;
denying the access request in response to detecting the access anomaly;
generating, based on the unfavorable access pattern, an anomaly detection indicator identifying the requestor; and
sending the anomaly detection indicator to other devices of the storage network.
2. The method of claim 1 , wherein the method further comprises:
initiating a secondary authentication process with the requestor;
receiving a secondary authentication response from the requestor; and
processing the access request when the secondary authentication response is favorable.
3. The method of claim 1 , wherein the method further comprises:
storing the access request in a local memory; and
associating the access request with at least one other access request, wherein the at least one other access request includes a request for the set of encoded data slices.
4. The method of claim 3 , wherein processing the access request includes:
extracting the at least one other access request associated with the access request; and
processing the access request and the at least one other access request in a sequence in accordance with a request type of the access request.
5. The method of claim 4 , wherein the access request and the at least one other access request include a write request, a commit request, and a finalize request of a three-phase storage process.
6. The method of claim 1 , wherein the access request is received via a dispersed storage and task (DST) processing unit that received the access request from the requestor.
7. The method of claim 1 , wherein detecting the unfavorable access pattern corresponds to one of a plurality of anomaly types.
8. The method of claim 1 , wherein detecting the access anomaly includes receiving a second anomaly detection indicator from another storage unit.
9. The method of claim 1 , wherein the anomaly detection indicator includes the access request.
10. The method of claim 1 , wherein another storage unit receives another access request associated with the requestor corresponding to the access request and queues the another access request in response to receiving the anomaly detection indicator.
11. A processing system of a storage network comprises:
at least one processor;
a memory that stores operational instructions that, when executed by the at least one processor, cause the processing system to perform operations that include:
detecting an access anomaly associated with an access request from a requestor for a set of encoded data slices, the access anomaly having an unfavorable access pattern, wherein the set of encoded data slices is dispersed storage error encoded and stored in at least one storage unit of the storage network;
denying the access request in response to detecting the access anomaly;
generating, based on the unfavorable access pattern, an anomaly detection indicator identifying the requestor; and
sending the anomaly detection indicator to other devices of the storage network.
12. The processing system of claim 11 , wherein the operations further include:
initiating a secondary authentication process with the requestor;
receiving a secondary authentication response from the requestor; and
processing the access request when the secondary authentication response is favorable.
13. The processing system of claim 11 , wherein the operations further include:
storing the access request in a local memory; and
associating the access request with at least one other access request, wherein the at least one other access request includes a request for the set of encoded data slices.
14. The processing system of claim 13 , wherein processing the access request includes:
extracting the at least one other access request associated with the access request; and
processing the access request and the at least one other access request in a sequence in accordance with a request type of the access request.
15. The processing system of claim 14 , wherein the access request and the at least one other access request include a write request, a commit request, and a finalize request of a three-phase storage process.
16. The processing system of claim 11 , wherein the access request is received via a dispersed storage and task (DST) processing unit that received the access request from the requestor.
17. The processing system of claim 11 , wherein detecting the unfavorable access pattern corresponds to one of a plurality of anomaly types.
18. The processing system of claim 11 , wherein detecting the access anomaly includes receiving a second anomaly detection indicator from another storage unit.
19. The processing system of claim 11 , wherein the anomaly detection indicator includes the access request.
20. The processing system of claim 11 , wherein another storage unit receives another access request associated with the requestor corresponding to the access request and queues the another access request in response to receiving the anomaly detection indicator.
