2. vCloud Cell Design Examples : 2.2 Secure Certificates : 2.2.1 Background
   
2.2.1 Background
Security is a critical component of a successful vCloud deployment. Before you can install and run VMware vCloud Director you must implement certificates and key management for secure access and authentication to the vCloud Director server. The following example shows how to implement security features designed to safeguard data, keep out intruders, and allow access to legitimate users.
Using the SSL/TLS protocol in the vCloud environment provides secure communication between the end-tenant (client) and vCloud Director cell (server). Providing secure communication requires:
*Confidentiality and privacy of communication.
*Message integrity and hashing.
*Authentication.
