Network Security
1. Traffic Interception & MitM
Network security centers on protecting data in transit. In a Man-in-the-Middle (MitM) attack, an adversary positions themselves between your device and the destination server (like a public Wi-Fi router), intercepting or altering your requests.
Common MitM attacks use ARP Spoofing to link the attacker's MAC address to the local gateway's IP address, forcing local traffic to route through the attacker's device before hitting the internet.
2. Defense and Encryption Tunnels
• HTTPS (TLS): Encrypts the payload between the browser and the web server. Eavesdroppers on the network only see encrypted garbage text, blocking data theft.
• Virtual Private Networks (VPNs): Creates an encrypted tunnel for all your system traffic to a remote gateway, hiding your traffic patterns and destinations from local ISP/network snoops.
• WPA3: The latest Wi-Fi security standard offering stronger cryptographic protection for wireless logins.
