Write short note on proxy firewall.

A proxy firewall is like a bouncer for your computer network, making sure only the right applications get in and out. It’s super secure because it doesn’t let information directly pass through. Instead, it acts like a middleman: when your computer wants to connect to something, it talks to the proxy, and the proxy then starts a new connection to the outside world.

This “middleman” setup stops direct connections and makes it tough for sneaky intruders to figure out where your network is located. It’s like keeping the entrance to a secret club hidden. The proxy firewall doesn’t just give internet access; it’s mainly there to keep your network safe. It filters, caches, logs, and controls requests, acting like a security guard to keep out bad stuff like intruders and viruses. So, it’s not just letting anyone stroll into your network party – it’s keeping things under control!
