Which method is commonly used to detect network intrusions in marine environments?

Intrusion Detection Systems (IDS) are specifically designed to monitor network traffic for suspicious activities and potential breaches. In marine environments, where systems are crucial for safety and operational integrity, IDS can analyze incoming and outgoing traffic to identify anomalies that may indicate an intrusion attempt. This method is essential for detecting unauthorized access or misuse of network resources, allowing for timely responses to potential cybersecurity threats.

While firewall systems play a role in filtering traffic to prevent unauthorized access, they do not actively monitor for intrusions in the same way that an IDS does. Physical inspections, although important for ensuring the operational integrity of equipment, do not address the cybersecurity aspects of network monitoring. Regular network speed tests, while helpful for assessing performance, do not provide insights into network security or the detection of intrusions. Thus, the use of an Intrusion Detection System is the most effective and relevant method for detecting network intrusions in marine environments.
