Preventing Data Leakage to a Public Cloud

Public sector organisations across the world are looking to embrace cloud services with the objective of reducing overall IT spend through use of shared services.

Within the UK public sector, cloud technology is considered "good" for Impact Level1 0 (IL0) and IL1 level data (80% of data), but not suitable for the higher impact levels (20% of data). To facilitate adoption of the cloud, the risk that higher impact level data may leak needs to be managed.

Nexor, experts in connecting, transforming and protecting sensitive information in cyberspace, has developed a proof-of-concept to show how its solutions that have been tried and tested in cross domain environments can be suitably adapted to meet the needs of the cloud.

The proof-of-concept shows how a content-filtering proxy can intercept typical web application data, in this case Microsoft SharePoint data, and make a release decision. The concept applies equally well to other cloud applications and platforms.
