Firewalls
In the computing domain, a firewall is considered as a network security system, which on the basis of predetermined security rules, controls the incoming as well as outgoing network traffic. A firewall generally acts as a barrier between the internal network, which is secure and the external network like the internet, which is assumed to be not secure.
In general terms, there are two types of firewalls:
1) Network Firewalls
2) Host based Firewalls
Host based Firewalls are installed on the node or a specific desktop computer, for its protection and is generally used in conjunction with a network firewall. The network firewalls are installed at the perimeter of the network, which needs the protection.
VPN (Virtual Private Network)
A VPN (Virtual Private Network) generally extends a Private Network to the public network area. A VPN can let users, send as well as receive data across the public networks or the shared networks, emulating the condition of direct connection between the computer devices and the private network. It is evident that the applications running on VPN benefits from the security, functionality and management of the private network.
The VPN systems are classified as follows:
- Protocols which are utilized to tunnel the traffic.

- Topology of connections like “network to network” or “site to site”
- Levels of Security provided
- Number of simultaneous connections
