Intrusion detection is the process of monitoring and analyzing computer systems and networks for signs of unauthorized access or malicious activity.
Intrusion detection is a critical aspect of cybersecurity for IoT systems, which are increasingly connected and vulnerable to cyber attacks. Intrusion detection involves the use of specialized security controls and technologies, such as network-based intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS), to monitor and analyze the traffic and activity of devices and networks for signs of unauthorized access or malicious activity.IoT-specific intrusion detection techniques may include anomaly detection, which looks for unusual patterns of behavior that could indicate a security breach, and threat intelligence, which uses information about known cyber threats to identify potential attacks in real time. Intrusion detection also involves the development and implementation of security policies and procedures, such as incident response plans and disaster recovery plans, to ensure the confidentiality, integrity, and availability of information in the event of a cyber attack.Effective intrusion detection is essential to protecting IoT systems against cyber threats, which can compromise sensitive data, disrupt operations, and even pose risks to human safety. With the increasing adoption of IoT devices in critical infrastructure, healthcare, and other industries, the need for robust intrusion detection capabilities will only continue to grow.
