Web and video conference call security:



In addition to the same security features as in an audio conference call be sure that your Web and video conferences have the following conference call security features in place:



*End-to-end encryption of the data link. Most use Secure Sockets Layer (SSL) and 128-bit AES encryption to protect your data stream from snoopers.



*Secure control over desktop sharing when sharing your keyboard and mouse during collaboration.



By using the security features built into most conference call solutions and practicing some basic security precautions you can keep your meetings and vital data safe from competitors and hackers.
