What Is an Intrusion Detection System (IDS/IPS)? How Attack Detection Works
How does attack detection work? We explain the difference between IDS and IPS, signature vs anomaly detection, network vs endpoint approaches, the false positive problem, and how modern organizations catch attacks.
What Is an Intrusion Detection System (IDS/IPS)? How Attack Detection Works
Quick answer: Attack detection is the process of noticing malicious activity against your network or systems. An IDS sees an attack and raises an alert, an IPS goes further and blocks the traffic. Detection works two ways, matching known attack signatures and catching anomalies that deviate from normal behavior. Effective detection pairs these with SOC monitoring and EDR.

IDS vs IPS
IDS alerts but lets traffic pass, IPS sits inline and drops the malicious packet, more protective but needs careful tuning.
Two methods
Signature based, fast but misses novel attacks. Anomaly based, catches new attacks like APTs but more false positives.
Network vs endpoint
NIDS watches traffic, EDR watches endpoint processes, combine both in a SIEM with a tiered SOC.
FAQ
IDS or IPS? Most modern tools combine both. I have a firewall, do I need this? Yes, different jobs. Who runs it? A team must watch alerts, else use managed security.
