A Citrix Engineer needs to implement Application Firewall to prevent the following tampering and vulnerabilities:
-If web server does NOT send a field to the user, the check should NOT allow the user to add that field and return data in the field.
-If a field is a read-only or hidden field, the check verifies that data has NOT changed.
-If a field is a list box or radio button field, the check verifies that data in the response corresponds to one of the values in that field.
Which security check can the engineer enable to meet this requirement?
