Which of the following is an advantage of using machine learning in intrusion detection?

Using machine learning in intrusion detection significantly enhances the effectiveness and efficiency of threat detection processes, particularly by reducing the time needed to detect unknown threats. Traditional signature-based intrusion detection systems often rely on pre-defined patterns or known threats. This means they can lag in identifying new, previously unseen attacks, as they depend heavily on historical data.

In contrast, machine learning algorithms are designed to identify patterns and anomalies within large datasets. By learning from existing data, these algorithms can adapt and recognize new attack vectors that do not match known signatures. This ability to detect anomalies or deviations from normal behavior enables quicker identification of potential threats, allowing organizations to respond proactively before any significant damage can occur. Such rapid detection is critical in a cybersecurity landscape that is constantly evolving, where threats can emerge without prior indication or documentation. Thus, the advantage lies in the system's proficiency in adapting to new and unknown threats, mitigating risk effectively.
