Q. When the User ID and Password are passed from the desktop to the server, is HTTP Authentication, NT LAN Manager (NTLM) v2, or Kerberos used?
A. Cisco MeetingPlace Web is setup with Internet Information Services (IIS) to use Web Authentication (HTTP Authentication). It can also be setup with IIS to use Windows Integrated Authentication.
According to Microsoft’s article, Windows Integrated Authentication uses Kerberos version 5 and NTLM authentication. The actual protocol it uses depends on the client OS platform and the client browser support of the protocol.
Many customers use the “Integrated NT Authentication” method. It, however, requires additional work from MeetingPlace Professional Services to create a custom start page (to remove the domain name) and to resolve case and length issues (for user names).
In all cases, the password is encrypted (shown as a hash in the IIS log), but the User ID is not. The encryption used with Web Authentication, however, is a well-known encryption algorithm and can be easily cracked. For true security, it is best to deploy Secure Socket Layer (SSL).
Q. Is the traffic from Cisco MeetingPlace Desktop Sharing encrypted? If so, what protocol is used?
A. You can install a Secure Socket Layer (SSL) certificate and conduct conferencing through the HTTPS protocol, to encrypt Cisco MeetingPlace Web Conferencing. The same SSL encryption also applies to the Cisco MeetingPlace Web Login interface.
Note: All Cisco MeetingPlace Web Conferencing packets are sent over the same channel: direct (1627), HTTP, or HTTPS. If HTTPS is not used, the packets are not encrypted.
