Precautions

The default approval template takes effect if you do not set approval processes for tickets that are used to change the sensitivity levels of sensitive columns under the Approval Rule Validation checkpoint. In the Switch Approval Template dialog box, you can change the approval process of the default approval template.

Basic configuration items

Checkpoints

When you submit a ticket to change the sensitivity levels of sensitive columns, DMS checks whether the ticket conforms to rules that are specified under the checkpoints. Approval Rule Validation: When you submit a sensitive column change ticket to change the sensitivity levels of sensitive columns, DMS checks whether the ticket conforms to rules that are specified under the Approval Rule Validation checkpoint. You can use the default rules that are provided in the templates of security rules, or create a custom rule. For more information about how to create rules, see Create a rule.

Factors and actions

• Factors
  A factor is a predefined variable in DMS. You can use factors to obtain the context to be validated by security rules. The context includes SQL statement categories and the number of rows to be affected. A factor name consists of the prefix @fac. and the display name of the factor. Each module of the Security Rules tab provides different factors for different checkpoints. The following table describes the factors that are provided for the checkpoints in the Sensitive Column Change module.

  Factor

  Description

  @fac.column_level_change_type

Valid values: upper: Change the sensitivity level to a higher level, including the following 3 cases: Change the sensitivity level from internal to sensitive.

Change the sensitivity level from sensitive to confidential. sensitive_to_inner: Change the sensitivity level from sensitive to internal. confidential_to_sensitive: Change the sensitivity level from confidential to sensitive. confidential_to_inner: Change the sensitivity level from confidential to internal.

• Actions
  An action in a security rule is an operation that DMS performs when the IF condition in the rule is met. For example, DMS can forbid the submission of a ticket, select an approval process, approve a ticket, or reject a ticket. An action in a security rule shows the purpose of the security rule. An action name consists of the prefix @act. and the display name of the action. Each module of the Security Rules tab provides different actions for different checkpoints. The following table describes the actions that are provided for the checkpoints in the Sensitive Column Change module.

  Action	Description
  @act.forbid_submit_order	Forbids a ticket from being submitted. The statement is in the following format: @act.forbid_submit_order 'Reasons for forbidding the ticket from being submitted'.
