Intrusion Detection Systems

Intrusion Detection Systems (IDS) are security frameworks designed to monitor and analyze network or system activities for malicious activities or policy violations. An IDS works by inspecting traffic patterns, logs, and system behaviors to identify potential security breaches, unauthorized access attempts, or other types of malicious activity. Once a threat is detected, the system can generate alerts for administrators, allowing them to respond appropriately to mitigate risks.There are generally two types of Intrusion Detection Systems: Network-based IDS (NIDS), which monitors traffic on a network to detect any suspicious activity, and Host-based IDS (HIDS), which focuses on monitoring individual devices or hosts for signs of intrusion. IDS can utilize various detection methods, including signature-based detection, which relies on known attack patterns, and anomaly-based detection, which identifies deviations from normal traffic patterns or behaviors.Overall, IDS plays a critical role in maintaining cybersecurity by providing real-time monitoring, alerts, and investigative capabilities to help organizations identify and respond to security threats effectively.
