  Introduction Firewall  A computerfirewall is a router or other communications device which filters access to a protected network.  Firewall is also a program that screens all incoming traffic and protects the network from unwelcome intruders. Proxy Server  Proxy Server is a computer program that acts as an intermediary between a web browser and a web server. To give users rapid access to popular web destinations.  Internet Service Providers use proxy servers as "holding bins" to store frequently requested pages, rather than going out and fetching them repeatedly from the Net

  Body • A proxyfirewall is considered the most secure form of firewall because it prevents networks from directly contacting other systems. It has its own Internet Protocol (IP) address, which means an external network connection cannot receive packets directly from the network. • A proxy firewall works by providing a single point that enables organizations to assess the threat level of application protocols and implement attack detection, error detection, and validity checks. It uses tactics like deep packet inspection (DPI) and proxy-based architecture to analyze application traffic and discover advanced threats.

  Conclusion • A firewallnot only reduces the risks to the internal network, it can provide enhanced privacy to not allowing services such as finger and the Domain Name Service. In addition, a firewall can be used log access to and from the internal network, and to keep statistics about network usage. As the Internet becomes more a part of business, firewalls are becoming an important ingredient of an overall network security policy. • A proxy server is an intermediary between end users and the internet that offers benefits such as: Improving security. Providing anonymity. Improving browsing speed. Allowing for control over internet usage
