Types of Firewall

1. Packet filter:

Packet filtering inspects each packet passing through the network and accepts or rejects it based on user-defined rules.

2. Circuit-level firewall: 

Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.

3. Application gateway: 

Applies security mechanisms to specific applications, such as FTP and Telnet servers.

4. Proxy server: 

Intercepts all messages entering and leaving the network acting as an intermediary between clients and servers. The proxy server hides the true network addresses
