IDS
(Intrusion Detection System)
Security software that watches systems or network traffic and alerts on suspicious activity
What's it for?
Watches for suspicious activity and warns people when something may be trying to break in.
For example…
Network IDS alerts when a server starts scanning internal ports it never touched before
An IDS notices repeated connection attempts across unusual ports and raises an alert for the security team to investigate.
Think of it like…
Burglar alarm that rings — it tells you something is wrong; it does not bolt the door shut by itself
