<p>
Specifies whether log file integrity validation is enabled. The default is false.
</p>
<note>
<p>
When you disable log file integrity validation, the chain of digest files is broken after one hour. CloudTrail
does not create digest files for log files that were delivered during a period in which log file integrity
validation was disabled. For example, if you enable log file integrity validation at noon on January 1, disable
it at noon on January 2, and re-enable it at noon on January 10, digest files will not be created for the log
files delivered from noon on January 2 to noon on January 10. The same applies whenever you stop CloudTrail
logging or delete a trail.
