Which of the following suggested usage of cyber defense system is correct:

The selection that all the given options are correct reflects an accurate understanding of the roles and uses of various cyber defense systems.

Encryption is indeed a fundamental security measure employed to safeguard sensitive information, ensuring that data is unreadable without the correct decryption key. This technique is essential for protecting data at rest and in transit, thus preserving the confidentiality and integrity of sensitive information.

Host-based Intrusion Detection Systems (HIDDS) are specifically designed to monitor the activities on individual machines or systems. They analyze system calls, file access patterns, and other such activities to identify potential security breaches or malicious activities, enhancing the security of each host.

Similarly, Network-based Intrusion Detection Systems (NIDDS) monitor traffic on a network to detect suspicious patterns or anomalies. These systems protect the entire organizational network by analyzing data packets and traffic flows, helping to identify and respond to threats at the network level.

Since each statement accurately describes a key aspect of cyber defense systems, choosing the option that includes all these points is the best answer. Each component plays a critical role in reinforcing an organization’s overall security posture.
