IDS( Intrusion Detection System)

Learning Outcome

Let's Recall Firewall Basics

A Firewall is a security system that controls incoming and outgoing network traffic.

A large bank hired Faisal as the security guard at the main entrance of its headquarters.

His job was simple: check everyone coming in and block suspicious people.
In cybersecurity, Faisal represents the firewall.

Most threats were stopped at the gate.

But one day, a hacker managed to get inside the bank’s network using stolen login credentials that looked completely valid.

To Faisal, the hacker looked like a normal employee, so he passed through without raising suspicion.

Now the danger was already inside the building.

Luckily, the bank had another layer of security.

CCTV cameras were installed across every hallway, vault room, and server area.

Imran carefully watched for suspicious behavior patterns

All the camera feeds were connected to a smart monitoring room where a security analyst named IDS Imran worked day and night.
