Cipher is an algorithm for encrypting and decrypting data.
During the SSL handshake between client and server, the
cipher level is negotiated. A low cipher level should only be
used for systems that do not transmit any important
information.
High: This currently means cipher suites with key
lengths larger than 128 bits, and some with 128-bit
keys.
Medium: This currently means cipher suites using 128-
bit encryption.
Low: This currently means cipher suites using 64- or
56-bit encryption algorithms but excluding export cipher
suites.
Select how the server-client authentication should be handled:
Mutual Authentication: MTLS is used by
Microsoft
®
Office Communications Server 2007 Server
roles and by Microsoft
®
Exchange 2007 UM role to
communicate with each other. In this mode, both peers
need to authenticate each other and both client and
server exchange certificates.
For connecting to Microsoft
®
Office Communications
Server 2007 R2 Mediation Server via TLS, use Standard
TLS authentication mode. For connecting to
Microsoft
®
Lync Server or Exchange 2007 UM role via
TLS, use MTLS authentication mode.
Standard TLS Authentication: This is the normal
authentication mode, in which the client asks the server
for authentication to ensure a secure connection to the
correct server.
No Authentication: In this mode, neither the server
nor the client needs to prove its authentication.
The default setting is Standard TLS Authentication.
If enabled, the expiration date of the peer certificate is verified.
If the certificate is expired, an informational message is
displayed and the call is aborted.
