Among the indicators of insider threats, which is the most common?

• A. No Changes in Network Usage Patterns
• B. No Temporal Changes in Revenue
• C. Multiple Failed Login Attempts
• D. All the above

Answer: (C)

Multiple failed login attempts are a significant indicator of insider threats because they can suggest an employee is attempting to access systems or information to which they should not have access. This behavior may point to malicious intent, such as attempting to gain unauthorized entry to sensitive data. It reflects a proactive effort by the insider to compromise security measures in place, often preceding a more serious breach. While a lack of changes in network usage patterns could also signify unusual behavior, it is less direct in indicating malicious intent compared to failed login attempts. Similarly, no temporal changes in revenue, while potentially relevant in a financial context, does not specifically pinpoint insider threats. It may result from various external factors unrelated to insider activities. Thus, multiple failed login attempts stand out as a more immediate and recognizable symptom that raises red flags in assessing the potential for insider threats.
