b. A firewall appliance that runs on a LAN
c. A firewall that runs in an endpoint virtual machine
d. A firewall that blocks only incoming traffic

Answer 1

A virtual firewall is a firewall that runs in the cloud. It operates within a virtualized infrastructure, providing protection to virtual machines, applications, and data. It offers flexibility, scalability, and cost-effectiveness compared to traditional hardware firewalls.

Step-by-step explanation:

A virtual firewall is a firewall that runs in the cloud. It is a network security solution that is implemented in a virtual environment. Instead of using physical hardware, a virtual firewall operates within a virtualized infrastructure, providing protection to virtual machines, applications, and data.

One example of a virtual firewall is the Cisco ASAv (Adaptive Security Virtual Appliance), which runs in a virtualized environment and can be deployed in a cloud-based infrastructure. It offers the same functionalities as a physical firewall, such as filtering incoming and outgoing traffic, monitoring network activity, and enforcing security policies.

Virtual firewalls provide flexibility, scalability, and cost-effectiveness compared to traditional hardware firewalls. They can be easily deployed, managed, and scaled up or down as needed. Additionally, they offer advanced features like intrusion detection and prevention, VPN support, and traffic encryption.
