Virtual Appliance Security

Correct Answer: Regularly update the virtual appliance software

Regularly updating the virtual appliance software ensures the latest security patches and features are included, reducing vulnerabilities. Disabling network monitoring would decrease security. Decreasing the number of virtual appliances would not necessarily increase security. Ignoring patches or updates leaves the appliance exposed to vulnerabilities. Exposing the virtual appliance directly to the internet would increase the risk of attacks. Granting root access to all users increases the risk of unauthorized access.

Correct Answer: Proper network segmentation

Proper network segmentation helps increase security by creating segregated zones that separate different types of network traffic. Lowering firewall security settings would make the network less secure. Enabling unrestricted internet access freely allows any incoming and outgoing traffic without proper security checks. Disabling virtualization support would hinder the deployment of virtual appliances. Installing the appliance on guest virtual machines can lead to additional security vulnerabilities. Ignoring resource isolation would allow potential cross-contamination of resources.

Correct Answer: Implement a virtual switch with security features

A virtual switch with security features helps maintain secure traffic flow in the virtual environment. Disabling hypervisor security settings would result in lesser security. Using weak passwords makes VMs more vulnerable. Disabling IPS would decrease network security. Allowing direct connection to external networks exposes the VM to potential attacks. Sharing the host operating system with VMs opens up potential vulnerabilities.
