7.4.6RDP encryption
RDP features data stream encryption, which is based on the RC4 symmetric cipher (with keys up to 128bit). The RC4 keys are being replaced in regular intervals (every 4096 packets).
RDP provides three different authentication methods:
1.Historically, RDP4 authentication was used, with which the RDP client does not perform any checks in order to verify the identity of the server it connects to. Since user credentials can be obtained using a man in the middle (MITM) attack, RDP4 authentication is insecure and should generally not be used.
2.RDP5.1 authentication employs a server certificate for which the client possesses the public key. This way it is guaranteed that the server possess the correspond- ing private key. However, as this
3.RDP5.2 authentication is based on TLS 1.0 with
While VirtualBox supports all of the above, only RDP5.2 authentication should be used in environments where security is a concern. As the client that connects to the server determines what type of encryption will be used, with rdesktop, the Linux RDP viewer, use the

The following command enables multiple connection mode:
VBoxManage modifyvm VMNAME
If the guest uses multiple monitors then multiple connection mode must be active in order to use them at the same time (see chapter 9.7, Multiple monitors for the guest, page 143).
