This chapter includes:

Key Management Interoperability Protocol (KMIP)
In this release, Caché can be a client to an enterprise key management server and use the Key Management Interoperability Protocol (KMIP) to store and retrieve keys on the server. These keys can be used to encrypt data at rest, such as databases and journal files. KMIP, an OASIS standard, gives you the power of centralized key management.
Microsoft Volume Shadow Copy (VSS) Integration
This release introduces Cache and Ensemble integration with Microsoft's Volume Shadow Copy Service (VSS) framework. This integration allows any backup product which supports VSS integration to identify databases and the volumes they reside on and seamlessly quiesce Cache and Ensemble instances when performing a backup of the system. The copies of the databases included in a VSS shadow are physically, although not logically with regards to transactions, consistent and therefore may be restored individually. To ensure the transaction integrity of these restored databases, one should also replay journal files accordingly.
Support for Microsoft Integrated Windows Authentication for HTTP Connections
This new enhancement allows %Net.HttpRequest to use windows based authentication over HTTP 1.1 to establish a connection to a secure server. Users can provide credentials or, if no credentials are provided, the system will try to authenticate using the current logged in context. Client may initiate a connection to the server with an "Authorization" header or try to establish a connection without that header and process the 401 status code with its associated with WWW-Authenticate header and then respond with the appropriate authentication mechanism. The supported authentication schemes are Negotiate (Kerberos & NTLM), NTLM, and Basic.
SSH Enhancements
Establishing SSH connections for Caché and Ensemble uses a new SSH library with multiple enhancements to functionality and performance.
