Certified Incident Handler (CIH) Practice Ecam

What indicator helps users identify potential security incidents on their mobile devices?

1. Network traffic spikes

2. Abnormal behavior of the applications

3. Slow device response

4. Battery drainage

The correct answer is: Abnormal behavior of the applications

The indication of abnormal behavior of applications serves as a critical signal for users to identify potential security incidents on their mobile devices. When applications begin to behave in unexpected ways—such as crashing unexpectedly, exhibiting unusual permission requests, or sending unsolicited data—it raises red flags that might point to malicious activity or vulnerabilities within the device. This can include instances where malware has infiltrated an app, or where a legitimate application has been compromised. Recognizing these anomalies is essential for users as it can prompt them to investigate further, potentially leading to the detection of malware, data breaches, or other security threats. Mobile devices are commonly targeted due to the sensitive information they contain, and recognizing abnormal application behavior can be a proactive measure in safeguarding against these threats. In contrast, while network traffic spikes, slow device response, and battery drainage can be indicative of performance issues or potential security problems, they are not as directly linked to the identification of security incidents as abnormal application behavior. For instance, a network spike may not always indicate a security breach—there could be legitimate reasons for increased traffic. Similarly, slow responses and battery issues can result from numerous factors, including software updates or hardware problems, rather than security threats directly. Thus, monitoring application behavior serves as a more immediate and clear
