Intrångsspårare

Intrångsspårare, often translated as "intruder tracker" or "intrusion detector," refers to systems or software designed to detect and report unauthorized access or activities within a computer network or system. These systems are a crucial component of cybersecurity, aiming to identify malicious actors, malware, or policy violations.

The primary function of an intrångsspårare is to monitor network traffic, system logs, and user behavior for patterns indicative of a security breach. This can include anomalies such as unusual login attempts, unexpected data transfers, or the execution of unauthorized commands. When suspicious activity is detected, the system typically generates alerts for security personnel, providing them with information to investigate and respond to the potential threat.

Intrångsspårare can be categorized into network-based intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). NIDS monitor network traffic flowing across a network segment, while HIDS focus on monitoring individual computers or servers for malicious activity. Modern intrångsspårare often employ a combination of signature-based detection, which looks for known attack patterns, and anomaly-based detection, which identifies deviations from normal behavior. The effectiveness of an intrångsspårare relies on its ability to accurately distinguish between legitimate and malicious activities, minimizing false positives while effectively identifying genuine threats.
