Why is it important for incident responders to be aware of abnormal behaviors on devices?

Understanding abnormal behaviors on devices is crucial for incident responders primarily because these anomalies often signify potential unauthorized access or other security incidents. When a device exhibits unusual patterns, such as unexpected high network traffic, unauthorized software installations, or changes in operating performance, it can be an early indicator of a cyber threat, such as a malware infection or an active breach.

By recognizing and investigating these abnormal behaviors promptly, incident responders can take necessary actions to mitigate risks, protect sensitive data, and prevent further damage. The ability to distinguish between normal and abnormal behavior allows responders to develop a more proactive approach to cybersecurity, reinforcing the organization's defenses against potential attacks.

While other options may touch on important aspects of device management—such as performance, maintenance, and application management—none relate directly to the immediate security implications that abnormal behaviors could signify. This emphasizes the need for vigilance and awareness in identifying potential threats through observed device behavior.
