What risk is associated with live VM migration lacking proper authentication?

The association of the risk with live VM migration lacking proper authentication lies in the potential for unauthorized actions that can significantly compromise the integrity and security of the virtual environment. When live VM migration occurs without robust authentication protocols, it becomes susceptible to exploitation by an attacker.

An attacker can exploit this vulnerability to migrate virtual machines to their own malicious infrastructure or to a victim's machine without authorization. This unauthorized migration allows the attacker to gain access to sensitive data, deployed applications, and overall control of the virtual machine. Therefore, the integrity and confidentiality of the information contained in the VM can be severely compromised.

This scenario underscores the importance of implementing strong authentication mechanisms during virtual machine operations, especially migrations, to prevent malicious actors from executing unauthorized actions that could lead to data breaches or service disruptions.
