how to hide sensitive Information on Ticket History

[Servicenow_12]

There could be times where some sensitive data could be inadvertently added to an issue in a text format, on a comment, description, or other forms (Fields, etc). For security reasons and due to this information needs to be removed/ Hidden.
Although the user can remove the text, the information will still be present on the history tab of the issue.
Since the history tab can't be disabled, Kindly help me with a way  to remove data from the history to hide the sensitive information

Hi @Harish KM ,

I have created one ACL on "sys_history_set" with restricting access for one of the role on Incident table. however, It made the only "History List " unavailable for the user who have that role , but ,the  "History Calender " is still available.

Please help me on how could i make the "History Calender " is unavailable for a particular role

Hi the only way to hide calendar is to remove the role from system property.

Read the below docs

Hi,

Is this a business requirement?

Because even admins can see the history details of the record.

Hi @Ankur Bawiskar ,

Yes, History should not be available for a specific role on a specific table record
