Cisco Cisco Unified Contact Center Enterprise 9.0(1) Folheto

The CTI OS (C++/COM toolkit) and CAD agent desktops both support TLS encryption to the server. 
This encryption protects agent login and CTI data from snooping. A mutual authentication mechanism 
was implemented for the CTI OS server and client to agree on a cipher suite used for authentication, key 
exchange, and stream encryption. The Cipher suite used is as follows:

Protocol: SSLv3 

Key exchange: DH 

Authentication: RSA

Encryption: AES (128)

Message digest algorithm: SHA1

 shows the encryption implementation's use of X.509 certificates on the agent desktops as well 

as on the servers. The implementation supports the integration with a Public Key Infrastructure (PKI) 
for the most secure deployment. By default, the application will install and rely on a self-signed 
certificate authority (CA) used to sign client and server requests. However, Cisco supports integrating 
with a third-party CA. This is the preferred method due to the increased security provided by a corporate 
managed CA or external authority such as Verisign.
