Final answer:
Intrusion detection systems (IDS) not only detect malicious software behavior, but they can also identify unauthorized access attempts and suspicious network traffic patterns.
Step-by-step explanation:
Intrusion detection systems (IDS) are designed to detect and respond to any unauthorized and malicious activity on a network. While their main purpose is to detect and prevent cyber attacks, IDS are not limited to detecting only malicious software behavior.
IDS can also identify and alert on other security breaches, such as unauthorized access attempts or suspicious network traffic patterns. For example, an IDS may detect a user attempting to access a restricted file or a sudden increase in outgoing network traffic, which could indicate a distributed denial-of-service (DDoS) attack.
In summary, while IDS are primarily focused on identifying and preventing malicious activities, they can also be configured to monitor and respond to other security breaches on a network.
