Use Case: Search & Security For Dropbox With Sap Hana & SearchYourCloud
This document outlines how the SearchYourCloud Enterprise Search and Security application, together with SAP HANA, is being used to secure and provide a fast, reliable full-text & near-natural-language search for the Dropbox for Business Cloud storage.
Dropbox for Business is the Dropbox Cloud storage and synchronization service specifically architected for the business marketplace to keep all of a user’s content in sync across multiple web-connected devices.
SAP HANA is an in-memory, column-oriented, relational database and business application service system created by SAP to deliver on-demand mission critical data.
The client is an organization that designs and delivers disruptive technology that positions hospitals to maximize savings from supplies and services through automated, Web-based sourcing applications.
To simplify the task of sharing, editing, and managing the gigabytes of information that are required to fulfill the service goals of the health industry, the client relies on Dropbox to maintain accessibility and version control for their corporate documents.
While Dropbox provides access controls and storage for the documents, its search and document-level encryption are not yet up to enterprise standards.
Within the client, both security and accessibility have become an issue as their document store becomes larger and larger. The ability to find a document instantly with a single search is vital to delivering the quality of service to which they aspire and on which their customers insist.
In addition to this accessibility, document security is paramount. Over the past year the health industry has come under attack, both from hackers gaining access to private and confidential information and from a press and public backlash about data being stored in such a way that the hackers were able to access and read the information.
Although used within the organization’s traditional firewalls, Mobile Device management (MDM) software was not viewed as a suitable solution for the security of cloud-based file stores, as these applications can only protect documents that are either on a mobile device or currently stored behind the corporate firewall. The documents themselves are still at risk while at rest in the cloud store and in transit from the cloud store to the user’s device.
SearchYourCloud server, with SAP HANA, running on a user’s desktop, mobile device and, within Microsoft Office, the SearchYourCloud application suite. By implementing the SearchYourCloud desktop and mobile suite of applications, we were able to maintain the complete Dropbox functionality, while at the same time making sure that all files and data stored within the file systems and databases are secured with AES 256 encryption levels, using keys that are owned and accessible only by the client.
This has enabled document-level encryption on all files, providing a completely secure at-rest and in-transit security layer, complementing the existing firewalls and MDM solutions that are already in place. In addition to the document-level security, we have also implemented our ciphered index. This enables users to have a full-text search across their content, while preventing hackers from gaining any knowledge about the content through its META data. The ciphered index is an instant-access index. When a user creates or saves a file, it is accessible to the search engine and available for a user to see within search results immediately. This unique functionality provides users with a superior search and security experience.
The complexities and overhead of searching encrypted data and having an instant-access index can be onerous. To make sure that there is no impact on operational speed or a lag in providing to the user the requested results or files, the SearchYourCloud Server is running on HCP. This enables the software to run at its optimum. The In-Memory database that HANA provides serves back the requests instantly, while other benefits of the HCP platform enable the SearchYourCloud software to respond to requests in a fast and expedient manner.
