Building data security in a networked computing environment
View Patent ↗In general, embodiments of the present invention provide an approach for providing a multi-tenant/customer partition group separator and securer in a shared cloud infrastructure (e.g., as an extension to DB2®, Label-Based Access Control (LBAC), and/or an independent tool). Among other things, embodiments of the present invention provide cloud administrators with an easy to use customizable, configurable security constraint builder/tool with a built-in multi-tenant/customer enabled security model. Moreover, embodiments of the present invention enable cloud administrators to set up, configure, and manage tenants/customers and their private shards with their own security constraints. The output of this tool greatly eases the time to create an invisible (e.g., software) wall of separation for multiple tenants/customers in a shared cloud infrastructure.
