Overview of Security

Cisco Unity Express provides the infrastructure for configuring and managing security certificates.

You can obtain these certificates using either of the following methods:

• Generate self-signed certificates using the RSA encryption algorithm with a modulus size from 512

to 1024.

Note For self-signed certificates, certain clients display a warning message and require

subscribers to accept the certificate.

• Obtain the certificates from the Certificate Authority (CA). Import these certificates from the

Cisco

Unity Express console or upload them from an FTP or HTTP server.

The certificates use either the Distinguished Encoding Rules (DER) or Privacy Enhanced Mail (PEM)

encoding formats.

Any feature which requires certificates to establish a secure connection can use this infrastructure.

Note This configuration and infrastructure apply only to Cisco Unity Express devices. For other

devices, see their respective device documentation.
