Which of the following is not a change type that Integrity Monitor watchlists observe?

Integrity Monitor in Tanium is designed to monitor changes to files and directories on endpoints. The changes it typically observes include modifications to the file content, permissions, and the creation of new files.

The correct answer, which is the type of change that Integrity Monitor does not specifically observe, is related to reading actions. When a file is read, its content is accessed but not altered, which means this action does not constitute a change that health checks or security assessments would focus on. Integrity Monitor is more concerned with activities that modify the state of the data, such as writing to a file or changing permissions, or creating new files, since these actions can impact system integrity and security.

Thus, while reading a file is an operation that happens frequently within a system, it does not affect the file's structure or permissions, making it outside the scope of what Integrity Monitor actively observes.
