The Security Castle
Think of network security like protecting a castle. Firewalls are the walls and gates - controlling who enters. Encryption is writing messages in secret code - even if intercepted, they can't be read. Access control is like guards checking IDs at doors. Penetration testing is hiring friendly spies to find weaknesses before enemies do. Backups are your treasure copies stored elsewhere. Defence in depth - multiple layers of protection!
