Security

« Customer Support | Main | System Requirements »

According to VoiceCafe documentation the security level enabled on all VoiceCafe products is very high and it includes: "…a cryptographically strong 1024 bit RC4 symmetric stream cipher in conjunction with an authenticated Diffie-Hellman key agreement Station-to-Station (STS) protocol. (RC4 is a very widely used cipher that has been employed by other industry leaders such as Oracle, Microsoft and IBM Lotus.)

Further security is provided by the addition of a new technique called "stateful key rotation," which is unique to the VoiceCafé product. This robust security protocol requires a session key to be communicated by a STS key exchange upon entry into a session. From that point on, unique 1024 bit symmetric keys are computed by combining key-primers with the session key using the mathematically secure one-way function MD5. These keys are used to encrypt every piece of data broadcast over the wire, including multicast messages.

VoiceCafé Web conferencing systems also use an authentication mechanism which employs RADIUS at its core coupled with another confidential security technique unique to VoiceCafé: A cascading series of bi-directional challenges and responses between each of the system components verifies the integrity of each part of the system before it is permitted to connect to a session."

Three levels of access security are available on the OfficeMaster:

The SUPER MODERATOR/ADMINISTRATOR - LEVEL 3
This security level provides for full Moderator access plus access to the Super Moderator page
In which you can add or delete new moderators.

MODERATOR ACCESS > LEVEL 2 - Enables all Moderator features EXCEPT the ability to ADD or DELETE new Moderators.

GUEST ACCESS > LEVEL 1 - For password protected Client entry pages.

The VoiceCafe OfficeMaster, like all other VoiceCafe products (except for MyCom), can provide full password protection of each virtual meeting room.
