About the tag/JavaScript change detection function

Recently, web tampering has involved the addition of malicious script or changing link tags rather than tampering with the visible content.
GRED WebCheck is equipped with a “script change detection engine” that analyzes and detects changes in JavaScript using its unique algorithm, and “link tag change detection engine” that detects changes in src and href attributes of specific tags within the HTML.
An emailed alert titled “Detection of changes to tags or JavaScript” is sent whenever the “script change detection engine” or “link tag change detection engine” detects such changes.
Clicking the URL included in the email or on the yellow “!” icon on the calendar of the management console displays a detailed report (detected URL, detected source code).
