What is difference between firewall and proxy

Start by defining each term individually. A firewall is primarily a security system that filters incoming and outgoing network traffic based on an organization's previously established security policies. Its main purpose is to establish a barrier between an internal network and incoming threats from external sources. On the other hand, a proxy server acts as a gateway between users and the internet. It provides indirect network services to a client, often processing user requests by forwarding them to the destination server. After defining, emphasize on their key functionalities and differences, such as a firewall's focus on blocking harmful traffic and a proxy's role in content filtering and providing anonymity. Make your explanation clear and concise, ensuring a solid understanding of both concepts and their distinct roles in network security and management.
