Intruder systems typically provide a range of services to help secure a network, such as:

• Monitoring:
  

  The system constantly monitors the network for any unusual activity that may indicate an attempted intrusion.

• Alerting:
  

  When an intrusion attempt is detected, the system sends an alert to network administrators, security personnel or other designated parties.

• Reporting:
  

  Intruder systems can generate detailed reports on intrusion attempts and other security-related events, providing insight into the nature and severity of threats.

• Blocking:
  

  Some systems can be configured to automatically block access from suspicious IP addresses or other sources.

• Analysis:
  

  Advanced intrusion detection systems can analyze network traffic and user behavior to detect patterns and anomalies that may indicate a security breach.

• Forensics:
  

  Intruder systems can also collect and store data on intrusion attempts for use in forensic investigations and legal proceedings.
