💡 WHAT THIS TEACHES: PERIMETER PACKET FILTERING & PROTOCOL SECURITY
Firewalls and Intrusion Prevention Systems (IPS) evaluate packet headers and state tables in microseconds. Ports like 23 (Telnet) transmit passwords in unencrypted plaintext, whereas 443 (HTTPS) encapsulates data in TLS sessions. High-volume SYN packets without corresponding ACKs indicate SYN Flood DoS attacks, while malformed SQL/Script fragments targeting web servers must be caught by deep packet inspection (DPI) before reaching production databases.
