Which action should be taken to secure virtual host machines effectively?

1. Only access hosts through a secure management interface

2. Allow unrestricted physical access to the host console

3. Share access credentials among team members

4. Disable network segmentation

The correct answer is: Only access hosts through a secure management interface

To secure virtual host machines effectively, accessing hosts through a secure management interface is crucial. This approach significantly mitigates risks associated with unauthorized access and potential breaches. A secure management interface encrypts communication, ensuring that sensitive commands and data are protected from interception or eavesdropping during remote management sessions. Using a secure management interface allows for the implementation of strong authentication methods, ensuring that only authorized personnel have access. This is essential in a virtualized environment where multiple virtual machines may be running on a single physical host, thereby increasing the attack surface. In contrast, allowing unrestricted physical access to the host console poses significant security risks, as it could enable unauthorized individuals to compromise the host and its virtual machines. Sharing access credentials among team members undermines accountability and increases the risk of credential leaks, making management and oversight difficult. Disabling network segmentation can expose virtual hosts to a wider array of threats, as it removes crucial barriers that protect different segments of the network from each other. Thus, accessing hosts through a secure management interface is a foundational practice in maintaining the security and integrity of virtualized environments.
