Network security monitoring (NSM) is essentially like having a really, really observant security guard constantly patrolling your digital property. Instead of a guard dog barking at intruders, NSM uses tools and techniques to continuously observe network traffic, looking for anything that seems out of place, suspicious, or downright malicious. Think of it as a detective work, but instead of fingerprints and clues left at a physical crime scene, the detectives are poring over packets of data whizzing across your network.
The goal of NSM isnt just to prevent attacks, although thats a nice bonus. Its more about gaining visibility into whats actually happening on your network. Its about understanding the normal flow of traffic, whats expected, and then identifying anything that deviates from that norm. Maybe someone is trying to access a server they shouldnt, perhaps a file is being exfiltrated to an unknown location, or maybe theres a suspicious pattern of requests that could indicate a botnet infection. NSM helps you uncover these activities before they cause serious damage.
