Threat Detection is like having a security system for computer networks and systems. It's about finding and stopping harmful activities before they cause damage to an organization's digital assets. Think of it as having digital security guards who constantly monitor for suspicious behavior, unauthorized access, or potential cyber attacks. This includes watching network traffic, checking system activities, and identifying unusual patterns that might indicate a security problem. Companies use various tools and methods for threat detection, similar to how a home security system uses different sensors and cameras to protect a house.
