Entropy computation in NetBackup
NetBackup 10.3 and later clients compute an additional risk signal in-line, called entropy. It improves the quality of detected anomalies. Entropy is a measure of randomness of file contents. Threat vectors that encrypt files tend to abruptly change the entropy. The entropy metric will be used with the anomaly detection in Veritas Alta View to help you detect such potential malicious activity. When this indicates anomaly activities, it is recommended to check the system for potential malicious actors and not to use those images as a recovery point if suspicious activities are found.
