You can filter headers that might contain authentication credentials or other sensitive information. The phrase "Header redacted for security" is saved instead. To specify headers to be filtered, create a system property `glide.atf.rest.log.header_blacklist` with a comma-separated list of header names to be filtered. For information on adding properties, see [Add a system property](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/t_AddAPropertyUsingSysPropsList.md). **Parent Topic:**[Administering REST test step configurations](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/automated-test-framework-atf/atf-administer-rest.md)
