Lyrics

[Verse 1]
Digital castles need their moats and walls
Network segments split the data halls
Like apartment buildings floor by floor
Each subnet gets its own front door
Traffic flows through designated lanes
While administrators hold the reins

[Chorus]
Firewalls filter, segments separate
Monitor traffic before it's too late
Block the bad, allow the good
Network security understood
Gates and guards at every turn
These are the lessons you must learn

[Verse 2]
Packet inspection reads each frame
Checking source and destination name
Rules and policies decide the fate
Which connections can communicate
DMZ creates a buffer zone
Where public servers stand alone

[Chorus]
Firewalls filter, segments separate
Monitor traffic before it's too late
Block the bad, allow the good
Network security understood
Gates and guards at every turn
These are the lessons you must learn

[Bridge]
VLANs divide without new wire
Honeypots catch the digital liar
IDS watches every byte
IPS blocks attacks on sight
Logs record the who and when
Security's your truest friend

[Verse 3]
Zero trust assumes the worst case
Every user proves their rightful place
Encryption scrambles data streams
Like secret codes in childhood dreams
Network boundaries drawn with care
Keeping dangers from your digital lair

[Chorus]
Firewalls filter, segments separate
Monitor traffic before it's too late
Block the bad, allow the good
Network security understood
Gates and guards at every turn
These are the lessons you must learn

[Outro]
Build your fortress bit by bit
Every layer helps you win
Network security's your shield
In this digital battlefield
