VeriSign is to provide security and authentication for the cloud-based Windows Azure platform.

The security giant said that Microsoft would be using its Secure Sockets Layer (SSL) certificates, and Code Signing Certificates, to create a layer of security for its Azure platform of cloud based services and applications.

Doug Hauger, general manager of Windows Azure at Microsoft, said: "With VeriSign SSL and Code Signing Certificates, VeriSign is providing proven safeguards that help ensure a trusted experience on the Windows Azure platform."

VeriSign's security tools will be use to protect services and applications delivered over the cloud. Currently Azure comprises a mixture of services including an operating system and developer and deployment tools. Microsoft said that by adopting it firms could reduce their costs and system complexity.
