Answer :
Final answer:
A sudden increase in network traffic is a potential insider threat indicator among the options provided, suggesting possible unauthorized data transfer. On the other hand, practices like strong password policies, regular updates, and data backups are protective measures. Monitoring and training regarding human factors in cybersecurity can help mitigate risks.
Explanation:
The potential insider threat indicator from the options provided is a sudden increase in network traffic. This can be a sign that someone inside the organization is transferring large amounts of data, possibly for malicious reasons such as a data breach or espionage. Other indicators include unexpected changes in employee behavior, unauthorized access, or attempts to access sensitive information. Strong password policies, frequent software updates, and regular data backups are, in contrast, standard security practices designed to protect against cyberattacks, rather than indicators of them.
It's essential for organizations to monitor for insider threat indicators through behavioral analysis and data trend monitoring. The impact of human factors on security operations can't be overstated as shown by the study on decision accuracy within an information security center which revealed that cognitive strain could lead to mistakes in threat detection. Thus, maintaining vigilance and providing ample decision-making support is critical in preventing and mitigating cybersecurity risks.
