The intrusion detection system (IDS) is a security technology designed to monitor network and system activities for malicious actions or policy violations. It analyzes traffic patterns, identifies suspicious activities, and generates alerts for administrators to investigate potential security incidents.
Intrusion detection system refers to a hardware or software application that automatically monitors events occurring in a computer system or network, analyzing them for signs of security breaches, unauthorized access, or abnormal behavior that could indicate an attack.
In cyber security, intrusion refers to any unauthorized access or attempt to access a computer system, network, or data. This can involve exploiting vulnerabilities to gain control over systems, steal sensitive information, or disrupt normal operations. Intrusion detection aims to identify and respond to these malicious activities.
