Cloud access security broker systems and methods with an in-memory data store
A method performed by a Cloud Access Security Broker (CASB) service includes scanning data stored in one of a cloud provider and a Software-as-a-Service (SaaS) application, wherein the data is for a user associated with a company of a plurality of companies; detecting an incident in a file or email in the data during the scanning; maintaining details of the incident in an in-memory data store, including a current snapshot of the file or email; and providing a notification to the tenant of the incident. The method can further include, subsequent to the incident and while the file or email is being updated, updating the details of the incident in the in-memory data store.

detecting an incident in a file or email in the data during the scanning;
maintaining details of the incident in an in-memory data store, including a current snapshot of the file or email; and
providing a notification to the tenant of the incident.
2. The method of claim 1 , wherein the steps further include:
subsequent to the incident and while the file or email is being updated, updating the details of the incident in the in-memory data store.
3. The method of claim 1 , wherein the incident is one of a Data Loss or Leakage Prevention (DLP) violation and malware.
4. The method of claim 1 , wherein the steps further include:
periodically storing records in the in-memory data store in a file for recovery.
5. The method of claim 1 , wherein the in-memory data store includes a multi-level hash for a record, for the incident.
6. The method of claim 5 , wherein the maintaining includes performing any of inserting, deleting, and updating the record, for the incident.
7. The method of claim 5 , wherein the multi-level hash include at least a hash based on the company and a hash based on an application name.
8. A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to implement a Cloud Access Security Broker (CASB) service, the CASB service comprising steps of:
scanning data stored in one of a cloud provider and a Software-as-a-Service (SaaS) application, wherein the data is for a user associated with a company of a plurality of companies;
detecting an incident in a file or email in the data during the scanning;
maintaining details of the incident in an in-memory data store, including a current snapshot of the file or email; and
providing a notification to the tenant of the incident.
9. The non-transitory computer-readable medium of claim 8 , wherein the steps further include:
subsequent to the incident and while the file or email is being updated, updating the details of the incident in the in-memory data store.
10. The non-transitory computer-readable medium of claim 8 , wherein the incident is one of a Data Loss or Leakage Prevention (DLP) violation and malware.
11. The non-transitory computer-readable medium of claim 8 , wherein the steps further include:
periodically storing records in the in-memory data store in a file for recovery.
12. The non-transitory computer-readable medium of claim 8 , wherein the in-memory data store includes a multi-level hash for a record, for the incident.
13. The non-transitory computer-readable medium of claim 12 , wherein the maintaining includes performing any of inserting, deleting, and updating the record, for the incident.
14. The non-transitory computer-readable medium of claim 12 , wherein the multi-level hash include at least a hash based on the company and a hash based on an application name.
15. A cloud-based system comprising:
a plurality of nodes communicatively coupled to one another, wherein the plurality of nodes include one or more processors configured to implement a Cloud Access Security Broker (CASB) service, where one or more nodes are configured to
scan data stored in one of a cloud provider and a Software-as-a-Service (SaaS) application, wherein the data is for a user associated with a company of a plurality of companies;
detect an incident in a file or email in the data during the scanning;
maintain details of the incident in an in-memory data store, including a current snapshot of the file or email; and
provide a notification to the tenant of the incident.
16. The cloud-based system of claim 15 , wherein one or more nodes are further configured to:
subsequent to the incident and while the file or email is being updated, update the details of the incident in the in-memory data store.
17. The cloud-based system of claim 15 , wherein the incident is one of a Data Loss or Leakage Prevention (DLP) violation and malware.
18. The cloud-based system of claim 15 , wherein one or more nodes are further configured to:
periodically storing records in the in-memory data store in a file for recovery.
19. The cloud-based system of claim 15 , wherein the in-memory data store includes a multi-level hash for a record, for the incident.
20. The cloud-based system of claim 19 , wherein the maintaining includes performing any of inserting, deleting, and updating the record, for the incident.
