Security Environments are:
• Support of 2048-bit encryption keys.

The certificate template used by your CA server may need modification to meet the
Collaboration Server requirements.
Certificate Requirements
Secure Mode
Table F-3 on page F-4 summarizes certificate requirements depending on the Skip certificate
validation for user logging session field.
Ultra Secure Mode
In Ultra Secure Mode, each Polycom device must have security certificates for the entire
Chain Of Trust.
The Collaboration Server must have:
• The public certificate of each server in the CA Chain or hierarchy that issued its
certificate.
For example: RootCA IntermediateCA SubCA
The public certificates of the chain that issued the administrator’s identity certificate. For
example: UserRootCA UserIntermediateCA UserSubCA
For more information seethe Ultra Secure Mode chapter, "Certificate Validation” on page 23-11
and "Certificate Revocation” on page 23-15.
Configure Certificate Management
Within a PKI environment, certificate revocation policies are used to ensure that certificates
are valid. Certificates can expire or be revoked for various reasons (RFC 5280).
The Collaboration Server enforces these certificate revocation policies through Certificate
Revocation Lists (CRLs). CRLs are required for each CA Chain in use by the Collaboration
Server. These CRL files must be kept current. For more information see the Ultra Secure Mode
chapter, "Certificate Configuration and Management” on page F-1 and "(PKI) Public Key
Infrastructure” on page 23-5.
Switching to Secure Mode
The following operations are required to switch the Collaboration Server to Secure Mode:
• Purchase and Install the SSL/TLS certificate
• Modify the Management Network settings
• Create/Modify the relevant System Flags
