Which of the following guidelines helps detect and prevent insider threats?

The choice indicating that all of the listed options are correct reflects a comprehensive approach to detecting and preventing insider threats. Each method plays an essential role in a holistic security strategy.

Using encryption methods for sensitive information is vital as it protects data confidentiality. Even if an insider attempts to access or misuse sensitive information, encryption ensures that they cannot easily read or exploit the data without proper authorization, thereby mitigating risk.

Monitoring admin activities is crucial for identifying unusual behavior that could indicate insider threats. Administrators often have elevated privileges, making them prime candidates for potential abuse. By closely watching their actions, organizations can detect anomalies that may signify malicious intent or policy violations.

Implementing non-repudiation techniques adds an extra layer of security by ensuring that actions taken within the system can be traced back to the individual accountable. This discourages malicious behavior, as individuals would recognize that their activities are being logged and reviewed, increasing the probability of detection.

In summary, a multi-faceted approach incorporating encryption, monitoring of administrative activities, and non-repudiation techniques collectively strengthens defenses against insider threats. Each method enhances security measures, making the choice reflecting all options the most accurate one.
