🌐 Ever wondered how a firewall protects your network. 🤔
Firewalls act as gatekeepers, monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. They ensure that only legitimate traffic passes through, safeguarding your data and network integrity.
🔍 Here’s a breakdown:
🔸 The client requests access to a server (e.g., webpage, database).
🔸 The request traverses the network.
🔸 The firewall intercepts the request, applying rigorous filtering rules.
🔸 Packets not meeting criteria are dropped, while approved ones proceed.
🔸 If checks are passed, the request is sent to the server.
🔸 The server processes and responds.
🔸 The response passes back through the firewall before reaching the client.
With various filtering mechanisms (application layer filtering, packet filtering, stateful inspection), firewalls are vital for a robust cybersecurity posture.
