Firewall and Proxy server

Question 1

What does Firewall do?

Answer 1

• It examines the traffic coming in and out of the network
• And ensures the traffic meets a certain criteria
• If traffic does not meet the criteria, it will block the traffic and warns the user of a possible security issue
• Firewall also can add undesirable IP addresses onto a blacklist so it cannot be accessed

Question 2

What does Proxy server do?

Answer 2

A proxy acts as an intermediary between the user’s computer and a web server so it prevents direct access to the webserver. It filters traffic and will block requests to certain websites if needed. It can prevent hacking and DDOS of the web server.
