Discover the definition of the term Nids (Network-Based Intrusion Detection System) presented by Les Assises de la Cybersécurité.

NIDS (NETWORK-BASED INTRUSION DETECTION SYSTEM)

A network intrusion detection system observes traffic on a branch of the network (usually from a strategic position) in order to detect attempted attacks, either from signatures (for known attacks) or by identifying abnormal behavior. The family of intrusion detection systems (IDS) thus includes NIDS on the network and HIDS (for Host-based intrusion detection system) on workstations.

The police also observe traffic in search of abnormal behavior. But we dissociate ourselves from any joke about chicken NIDS on the road.
