Does firewall encrypt data?
The firewall already has to accept all traffic so it makes sense to use an encrypted gateway anyway. If a machine is in one of these trusted locations, the traffic is unencrypted, so it no need to be configured in any other way but to use or benefit from the encryption.

What is difference between cloud and data center?
In a data center, data is most often stored on the premises of your organization. Some data centers may be in locations not owned by your organization—in this case, your data center is colocated, but not in the cloud. The cloud is completely off premises and your data is accessible from anywhere via the internet.
What is firewall with example?
Firewalls guard traffic at a computer's entry point, called ports, which is where information is exchanged with external devices. For example, “Source address 172.18. 1.1 is allowed to reach destination 172.18. 2.1 over port 22." Think of IP addresses as houses, and port numbers as rooms within the house.
What is a firewall explain any two types of firewall?
Stateless firewalls only analyze each packet individually, whereas stateful firewalls — the more secure option — take previously inspected packets into consideration. Proxy firewalls, also known as application-level firewalls, filter network traffic at the application layer of the OSI network model.
