What is a SOC?

The Security Operations Center, told as a story about a castle's guard room.

???

A castle has too many doors and windows.One person can't watch them all.

24day and night

A SOC is the castle's guard room.Every door and window is on a screen. Someone is watching at night and on weekends too.

Watch for red hat!— your watchtower friend

Notes from the watchtower go on the wall.The watchtower friend (CTI) says who's coming. The guard room sees who's here now.

Too many bells wear the guards out.A hundred cat alarms, and the real burglar walks right in.

In one breath

SOC = the guard room that watches every door day and night and runs when a bell rings.

Security Operations Center: people, screens and rules in one room. The hard part isn't spotting burglars — it's throwing out the cats fast.
