At the gate, the guard checks: β€’ Who you are β€’ Where you’re coming from β€’ Which flat you’re visiting β€’ Whether your name is on the list If everything matches rules β†’ you enter. If not β†’ you’re stopped. Firewall is that guard. Every incoming and outgoing packet is inspected against predefined rules. No emotion. Just matching conditions. βš™οΈ π—§π—˜π—–π—›π—‘π—œπ—–π—”π—Ÿ 𝗕π—₯π—˜π—”π—žπ——π—’π—ͺ𝗑 A firewall evaluates packets based on: β€’ Source IP β€’ Destination IP β€’ Source Port β€’ Destination Port β€’ Protocol (TCP/UDP/ICMP) β€’ Connection state There are main types: 1️⃣ Packet Filtering Firewall (Stateless) Checks packet headers only. Rule example: Allow TCP from 192.168.1.0/24 to port 80 Block everything else. It doesn’t remember previous packets. Fast. Basic. 2️⃣ Stateful Firewall Keeps track of active connections. It knows: β€’ This packet is part of an existing TCP session β€’ SYN β†’ SYN-ACK β†’ ACK sequence It maintains a connection table. Smarter. Safer. 3️⃣ Application-Level Firewall (L7) Inspects packet payload. Can block: β€’ Suspicious HTTP patterns β€’ SQL injection attempts β€’ Malicious content More powerful. More CPU heavy. πŸš€ π—¦π—¬π—¦π—§π—˜π—  π—Ÿπ—˜π—©π—˜π—Ÿ π—œπ—‘π—¦π—œπ—šπ—›π—§ Firewalls work using: Rule evaluation from top to bottom. First match wins. Poorly ordered rules: β€’ Increase latency β€’ Create accidental vulnerabilities β€’ Block legitimate traffic Also: Stateful firewalls consume memory to track sessions. At scale, connection tracking becomes expensive. Security always trades off with performance. 🎯 π—œπ—‘π—§π—˜π—₯π—©π—œπ—˜π—ͺ π—™π—Ÿπ—˜π—« Firewalls enforce security policies by evaluating packet headers and, in advanced cases, payload data against rule sets, optionally maintaining connection state for session-aware filtering.

Passwordless login in Linux uses SSH key pairs for secure authentication. A private key stays on your system, while the public key is added to the server. This eliminates password transmission and enables strong, cryptographic access control. Proper key management, passphrases, permissions, and rotation, is essential. #linux #software #computerscience #programming #cybersecurity
