Final answer:
The statement about Intrusion Detection Systems (IDS) preventing unauthorized entry is false. (The given statement is false)
Step-by-step explanation:
The statement 'Intrusion Detection Systems (IDS) prevent unauthorized entry' is false. IDS are designed to detect and alert potential security breaches, not to directly prevent them. These systems monitor network or system activities for malicious activities or policy violations and send an alert to a management station. While IDS do play an essential role in the security infrastructure, it is the task of other components, like Intrusion Prevention Systems (IPS) and firewalls, to actively block unauthorized access.
It's important to differentiate between intrusion detection and intrusion prevention. Intrusion Detection Systems identify and log potential threats and alert system administrators, while Intrusion Prevention Systems actively work to block these threats.
In the context of preventing the introduction of invasive species, technologies similar to IDS, such as trained sniffer dogs and X-ray equipment, are used at ports of entry to detect potential invaders. Again, the objective of these technologies is detection rather than prevention, with enforcement and penalties serving as the principal deterrent against the introduction of non-native species.
