Virtual Network Adapter

Virtual Network Adapter definition

Virtual network adapters work like physical network interfaces but in a digital way. It provides network connectivity for various software applications and virtual machines. Virtual network adapters operate in a simulation manner. In terms of cybersecurity, these operations are crucial because they can create isolated and secure network environments within virtual systems.

Common virtual network adapter types:

  • Bridged adapter: This virtual adapter uses the host computer’s network adapter to connect virtual machines to a network. That way, a virtual machine appears as the host in the same local network and allows direct interaction between other network devices.
  • NAT adapter (Network Address Translation): NAT adapters operate using the host’s IP address and permit VMs to access external networks, such as the internet, through the host’s machine’s network interface.
  • Internal network adapter: This type is used to create an isolated network that is only accessible by virtual machines within the same host system or network. It’s beneficial to create secure environments for testing and development purposes.
  • Host-only adapter: A host-only adapter creates a network for virtual machines and hosts only. That way, it forbids access to other external networks.
